The 28 Best Natural Supplements Proven to Reduce Anxiety and Stress

Research shows that most people prefer to take over-the-counter natural remedies to treat their anxiety instead of medication.

Perhaps you’re struggling with generalized anxiety, social anxiety, panic attacks, post-traumatic stress, OCD or a phobia…

The good news is that there are many natural supplements that can bring you relief and ease your chronic stress and anxiety.

And they are safe and don’t cause adverse side effects like anti-anxiety medicine.

This article lists the best natural supplements that are proven to reduce anxiety and stress.

These solutions are evidence-based and backed by research.

They have worked for me and for many other people.

It starts off with my top 10 personal favourites.

And then offers 18 other great options.

My Top 10 Favourite Supplements to Reduce Anxiety and Stress

1. Theanine

Theanine is a unique amino acid found in tea. It has a number of mental health benefits.

It’s known to produce a calming effect on the brain by crossing the blood-brain barrier and increasing the production of GABA, serotonin and dopamine in the brain. Unlike prescription anti-anxiety medication, it does not cause sedation and drowsiness (72-75).

Researchers have found that theanine supplements significantly reduce stress and anxiety, lower heart rate, and increase mental relaxation (77-81, 83).

Studies have also shown that theanine increases alpha brain waves and deactivates the sympathetic “fight or flight” nervous system (76, 82).

And animal research shows that it reduces “circulating biomarkers of stress” in rats (84-85).

I often take theanine alongside my morning coffee. It improves my mood, helps me focus and cancels out the jitters of caffeine. It’s sort of like meditation in a pill.

This anti-anxiety supplement contains theanine, along with several natural compounds that have helped me manage my anxiety over the years.

2. Magnesium

Magnesium is a vital mineral that participates in more than 300 biochemical reactions in your body.

It’s absolutely essential for the proper functioning of your nervous system and optimal neurotransmitter activity.

Nine different studies have found that magnesium supplements can reduce anxiety in humans and improve anxiety-related disorders (96-100).

And they start reducing anxiety quickly, often within one week (101).

Plenty of researchers have also found that magnesium has a relaxing effect in animals by calming the hypothalamic-pituitary adrenal (HPA) axis and activating GABA receptors. These are the same receptors activated by anti-anxiety medication (102-107).

Magnesium is included in this supplement.

3. Ashwagandha

Ashwagandha (Withania sominifera) is a popular Indian herb that has been used for more than 3000 years. It’s sometimes called the “Indian Ginseng”.

It’s known as an “adaptogen”, which is a compound that balances the body and restores normal bodily functioning after chronic stress.

A systematic review concluded that ashwagandha significantly reduces symptoms of stress and anxiety and is likely useful in the treatment of anxiety disorders (11).

In fact, two studies found that ashwagandha worked better than medication and psychotherapy at treating and reducing anxiety (12, 17, 19).

And other researchers have found that it reduces anxiety, decreases perceived stress, and improves the quality of life of people with anxiety disorders (13-16, 18).

Animal research also shows that ashwagandha causes anti-anxiety effects, reduces OCD-like behaviour and improves stress tolerance in rats (20-25).

So it’s a pretty amazing herb for anxiety!

But how does it work?

By increasing serotonin and GABA in the brain, and lowering cortisol levels by 25 per cent (26-29).

Ashwagandha is one of the herbs I took to help myself get off psychiatric medications.

That’s why it’s included in the Optimal Calm supplement.

4. Zinc

Zinc is an essential mineral for mental health, especially if you have chronic anxiety.

Like magnesium, it plays a key role in neurotransmission and nervous system functioning.

Researchers have found that zinc supplements can reduce symptoms of anxiety in both humans and animals (123-125).

I created and take the Optimal Zinc supplement to make sure my zinc levels are optimal.

I previously wrote about the link between zinc and anxiety in this post.

Zinc can also stimulate your vagus nerve, which reduces anxiety.

5. Bacopa

Bacopa is an adaptogenic herb.

It’s commonly used to improve cognition and memory, but it’s also very good at reducing anxiety.

Researchers have found that bacopa supplements reduce stress, anxiety and cortisol levels in humans (89-91, 94).

In fact, one of the ways bacopa improves cognition is by simply reducing anxiety (95).

So if you have anxiety, and it negatively impacts your thinking, bacopa is a good choice.

Animal studies also show that bacopa reduces the biochemical effects of acute and chronic anxiety in rats. It does this by significantly increasing serotonin and dopamine levels and significantly reducing stress hormone levels (92-93).

I took a bacopa supplement for a while. I found that it made me really relaxed and sleepy. I eventually stopped taking it because it made me too sleepy. But if you have very severe anxiety, it can be very helpful.

6. Probiotics

Probiotics have also been shown to reduce anxiety.

One study found that a probiotic supplement containing Lactobacillus Rhamnosus significantly reduced anxiety and stress in humans (46).

And animal research shows that Lactobacillus Rhamnosus reduces stress and anxiety-like behaviour in mice (47-48).

Bifidobacterium Longum is another probiotic that can reduce anxiety.

Individuals that took it for 30 days experienced less anxiety and psychological distress, and also had lower cortisol levels (49).

Bifidobacterium Longum also reduces anxiety-like behaviour in animals by stimulating the vagus nerve (50-51).

Both Bifidobacterium Longum and Lactobacillus Rhamnosus are included in the Optimal Biotics supplement.

And this older article includes 5 ways to increase your good gut bacteria.

7. Inositol

Inositol is a naturally-occurring molecule found in nearly all plants and animals. It plays a key role in various biological processes.

The brain has the highest concentration of inositol, where it plays an important role making neurotransmitters.

Inositol can be found in many foods, particularly fruit, especially cantaloupe and oranges.

But you need to supplement with it to reduce anxiety.

Researchers have found that taking an inositol supplement every day can significantly reduce anxiety in both adults and children. This includes a reduction in panic attacks and fewer symptoms of agoraphobia and obsessive-compulsive disorder (64-67).

In fact, research suggests that it’s as effective as an SSRI antidepressant in the treatment of anxiety and panic disorder (62).

And one study shows that it can reduce anxiety in people struggling with bulimia or binge eating (63).

Lots of animal research also shows that inositol reduces anxiety-like behaviour in rats (68-71).

It’s important to point out that the research suggests that you need to take high doses (12 to 18 grams daily) if you want to experience the anxiety-reducing benefits of inositol.

I took high doses of inositol powder when weening off psychiatric medication.

Check out my full post about inositol to learn more about the benefits.

Fun fact: Inositol is a white powder, so actors snort inositol instead of actual cocaine in television and movie scenes.

8. Valerian

Valerian (Valeriana officinalis) is an herb, and the root of the herb has traditionally been used to treat insomnia.

But it also can reduce anxiety.

Research shows that valerian root extract significantly reduces stress and anxiety (235-236).

Animal studies have also found that it reduces psychological stress and anxiety in rats and mice (259-265).

And in one study, Valerian demonstrated some anti-obsessive and anti-compulsive effects and therefore may help treat obsessive-compulsive disorder (234).

Scientists have collected a massive amount of research demonstrating that the compounds in Valerian naturally reduce stress and anxiety by:

• Partially activating serotonin receptors

• Maintaining serotonin levels

• Reducing stress hormone levels

• Binding to GABA receptors in the amygdala, a brain region associated with fear and anxiety

• Increasing GABA levels

• Inhibiting the breakdown of GABA in the brain (247-268).

As a result of this, it creates a calming effect similar to anti-anxiety drugs like Xanax and Valium.

This is why Valerian is often called “Nature’s Valium”.

Valerian is one of the first herbal remedies I took years ago to manage my anxiety at night and improve my sleep. It’s included in this anti-anxiety supplement.

Valerian supplements include the roots and stems of the plant.

But you can also take it as a tea or tincture if you want.

9. Cannabidiol (CBD)

Cannabidiol (CBD) is one of the active cannabinoids found in marijuana.

Unlike tetrahydrocannabinol (THC), CBD isn’t psychoactive and doesn’t make you “high”.

But it can help treat a number of diseases because it reduces inflammation.

Research has found that CBD oil significantly reduces anxiety in both healthy individuals and patients with social anxiety disorder (3-4).

It also significantly reduces anxiety, distress and discomfort caused by public speaking (5).

Researchers also think it can help people with panic disorder, obsessive-compulsive disorder and post-traumatic stress disorder (2).

This is because studies show that CBD activates serotonin receptors in the brain, increases GABA levels, lowers activity in the amygdala, and increases activity in the prefrontal cortex (6-10).

I used to take this CBD oil and highly recommend it. It significantly reduces my stress, makes me sleepy and knocks me out before bed.

Some people report that marijuana makes them anxious.

When I’ve smoked it in the past, it often made me anxious.

This is possibly because most marijuana has high levels of THC and lower levels of CBD.

Taking extra CBD may help.

One study found that CBD blocks the anxiety caused by THC (1).

10. Kava

Kava is a plant located in the western Pacific.

The root of the plant is used medicinally to treat anxiety and sleep disorders because it causes relaxation without impairing cognitive performance. Some people say it feels like drinking alcohol.

A meta-analysis concluded that kava can significantly reduce anxiety without very many side effects (30).

And numerous human studies show that kava can reduce all sorts of anxious symptoms, including tension, agitation, restlessness and phobias (32-34).

Researchers have compared a bunch of different herbal anti-anxiety remedies, and they found that kava is one of the most potent and effective options (35-36).

In fact, they think that kava should be a first-line treatment for anxiety because it’s so powerful and safe and works just as well as anti-anxiety medication (31, 37-38).

Studies even show that kava works similarly to benzodiazepines like Xanax by activating and strengthening GABA receptors in the brain (39-45).

I personally don’t take kava anymore because I get a weird reaction from it and I was able to confirm that I’m allergic to the plant.

But it works very well for many people, so that's why I'm including it in my top 10. 

Other Effective Anxiety-Reducing Supplements

11. Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that your body cannot produce itself, and they are absolutely necessary for the normal functioning of your brain and nervous system.

Numerous studies show that supplementing with omega-3 fatty acids significantly lowers inflammation and progressively reduces symptoms and feelings of anxiety (108-114).

Researchers have also found that supplementing with omega-3 fatty acids inhibits activation of the hypothalamic-pituitary adrenal (HPA) axis, which is involved in anxiety (108).

I recommend supplementing with krill oil, a special kind of fish oil that contains the essential omega-3 fatty acids.

I feel more anxious when I stop taking it. I actually notice the difference.

You can read more about the importance of omega-3 fatty acids here.

12. Chamomile

Chamomile is a medicinal herb that has been traditionally used for its calming and anti-inflammatory properties.

It contains essential oils and flavonoids that can help you relax.

Researchers have found that oral supplementation of chamomile significantly reduces anxiety and stress in patients with generalized anxiety (54-58).

Animal studies show that chamomile contains substances that act on the same parts of the brain as anti-anxiety drugs (52-53).

Apigenin, one of the main flavonoids in chamomile, reduces anxiety without sedation by enhancing GABA communication (59-61).

13. Passion Flower

Passion Flower represents a family of plants known as Passiflora.

There are about 500 known species of Passion Flower.

One species, Passiflora incarnata, has been shown to reduce anxiety and stress.

In one study, researchers found that Passiflora incarnata extract reduced generalized anxiety as much as a benzodiazepine. But it didn’t cause side effects that are common with anti-anxiety medication, such as cognitive impairment (213).

Two other studies show that supplementing with Passion Flower significantly reduces anxiety before surgery (214-215).

Animal research has found that it increases GABA, a neurotransmitter that reduces stress and anxiety (216-217).

Passion Flower is one of the first herbal remedies I took years ago to manage my anxiety. It’s included in this anti-anxiety supplement.

14. Lemon Balm

Lemon balm (Melissa officinalis) is a lemon-scented herb and tea known to reduce inflammation, lower cortisol and increase GABA levels in the brain.

As a result, it has a sedative effect, calming the nerves and relaxing the body.

Research shows that lemon balm extract significantly reduces anxiety and stress in humans (146-149).

In one study, researchers gave Cyracos, a standardized lemon balm extract, to individuals with anxiety disorders, and it significantly reduced their anxiety. As much as 95% of the subjects responded to the treatment, and 70% of them achieved full remission (145).

Animal studies also show that it reduces stress and anxiety in rats by reducing stress hormones and increasing serotonin and GABA. The effects are comparable to anti-anxiety medication (150-155).

Lemon balm is included in this anti-anxiety supplement. 

15. Rhodiola

Rhodiola, also known as golden root or arctic root, is a Traditional Chinese and Scandinavian herb.

It’s one of the most popular adaptogens used to increase physical and mental stamina.

Research shows that rhodiola supplementation significantly reduces anxiety and stress symptoms (86),

In one study, individuals with generalized anxiety disorder supplemented with rhodiola, and it significantly reduced their symptoms of anxiety (88).

Improvements can be seen within just three days of treatment (87).

I take rhodiola as needed. I find that it improves my mood and energy, especially after stressful periods of pushing myself too hard.

Rhodiola has a number of brain and mental health benefits. I previously wrote about it here if you’re interested in learning more.

16. Ginkgo Biloba

Ginkgo Biloba is a plant that has been used in China for thousands of years to treat a number of health problems.

It’s one of the top-selling natural supplements in the world, and it’s even a prescription herb in Germany.

It’s most commonly used to improve brain health because it increases blood flow to the brain and improves memory and attention in both healthy and unhealthy individuals.

But researchers have also found that it reduces anxiety and stress.

Two studies show that supplementing with Ginkgo Biloba significantly reduces anxiety compared to placebo (115-116).

This occurs in both elderly individuals with cognitive decline and younger people with generalized anxiety disorder (115-116).

And in healthy individuals, it reduces cortisol release during a stressful event (119).

Animal studies also show that Ginkgo Biloba has anti-stress and anti-anxiety effects in both mice and rats, without producing benzodiazepine-like side effects (117-118, 120-122).

Ginkgo Biloba is included in the Optimal Brain supplement. 

17. Vitamin B6

Vitamin B6 is a key nutrient that supports your entire nervous system.

It accomplishes this by playing a key role in the production of calming neurotransmitters in your brain, including serotonin and GABA.

Studies have found that Vitamin B6 supplements can reduce anxiety (126-128).

When I took antidepressants and benzodiazepines for my chronic anxiety, multiple functional and integrative doctors suggested I supplement with Vitamin B6.

This is because these medications can actually further deplete Vitamin B6, increasing anxiety in the long run.

If you take a medication to manage your anxiety, or simply have anxiety and want to manage it better, I recommend supplementing with Vitamin B6.

Vitamin B6 is included in the Optimal Calm supplement.

18. Vitamin C

Vitamin C is another way to reduce your anxiety and stress.  

Researchers have found that Vitamin C supplements significantly reduce stress and anxiety in humans and animals by limiting cortisol levels (129-136).

As you probably know, Vitamin C is found in fruits and vegetables such as green peppers, citrus fruits, tomatoes, cauliflower, Brussels sprouts, broccoli, and cabbage.

In addition to getting Vitamin C from fruits and vegetables, I take at least 100 mg of supplemental Vitamin C every day.

But based on my research and experience, if you want to reduce your stress and anxiety, you may have to take large doses of Vitamin C.

Two studies show that supplementing with a high dose (at least 3 grams) of Vitamin C reduces cortisol, psychological stress and anxiety (137-138).

I experimented with taking up to 10 grams of Vitamin C daily, and it definitely reduced my stress and anxiety when coming off several psychiatric medications.

That’s why it’s included in Optimal Calm.

19. Curcumin

Curcumin is the most heavily researched compound within turmeric, the spice that gives curry its yellow colour.

Research shows that it can reduce anxiety in individuals with major depressive disorder (139-141).

One animal study found that it reduces anxious behavior in rats (142).

Curcumin is a good option is you struggle with chronic inflammation and both depression and anxiety.

In my experience, it doesn’t help as much if you only have anxiety.

But it’s still one of my favourite natural compounds for the brain and mental health.

20. Lion’s Mane Mushroom

Hericium Erinaceus – better known as lion’s mane mushroom – is an edible mushroom with numerous health benefits.

It’s another one of my favourite supplements for brain health because it reduces inflammation and has antioxidant effects.

One study found that it reduced anxiety in 30 women after 4 weeks of supplementation (143).

And an animal study showed that it reduces anxious behaviour in rats by increasing neurogenesis (144).

This lion’s mane mushroom supplement is the highest-quality that I could find. I spent a lot of time researching and looking into different sources because not all lion's mane supplements are high-quality and effective, and I settled on this one.

21. Holy Basil

Holy Basil (Ocimum sanctum) is an adaptogenic herb that supports the body’s stress response. 

It’s known to have calming and relaxing effects on the body and mind.

In one study, researchers found that OciBest, a whole plant extract of Holy Basil, significantly reduced symptoms of stress. It was 39 per cent more effective than placebo, and there were no adverse effects (156).

Another study showed that supplementing with Holy Basil significantly reduces stress and anxiety in people with generalized anxiety disorder (157).

It’s also been shown to reduce cortisol (158-159).

And there is plenty of animal research showing that Holy Basil reduces anxiety, stress and stress hormone levels in mice and rats. And the anti-anxiety and anti-stress effects are comparable to antidepressant drugs (160-164).

Holy Basil can be taken as a supplement, herbal tea, dried powder, or fresh leaf used in cooking.

22. Saffron

Saffron is a spice derived from the Crocus sativus plant.

It has a number of health benefits due to the medicinal compounds within it.

Safranal and Crocetin, two of the compounds within saffron, have been shown to stimulate GABA receptors and increase serotonin levels in the brain (165-166).

Because of this, researchers have found that supplementing with a saffron extract can reduce anxiety (167).

Several preclinical and clinical studies show that supplementing with saffron significantly reduces stress and anxiety in adults and youth without side effects (169-173).

And one study found that the aroma of saffron significantly reduces cortisol levels and symptoms of anxiety in women (168).

Animal research also demonstrates that saffron reduced anxiety-like behaviours in mice (174).

23. Sceletium Tortuosum

Sceletium tortuosum is a plant commonly found in South Africa.

It’s a psychoactive herb but it doesn’t cause hallucinations or lead to addiction.

It often used before stressful events because research shows that it reduces anxiety and stress.

Researchers have found that it reduces anxiety and stress in humans by decreasing activity in the amygdala and inhibiting the reuptake of serotonin (175).

Animal studies have also shown that reduces anxiety and stress hormones (176-179).

Zembrin is the patented form of Sceletium tortuosum often found in supplements.

24. Lavender

Lavender is often used in soap and shampoo because it smells nice.

But it also has a number of health benefits.

Lots of research shows that lavender significantly increases calmness, relieves restlessness and nervousness, and reduces emotional distress in people with anxiety disorders – without causing any unwanted side effects (180-183).

One study found that Silexan, an oral lavender oil capsule, is just as effective at reducing generalized anxiety as lorazepam, a common benzodiazepine. And it didn’t cause side effects or addiction like the anti-anxiety medication (184).

Tons of other studies show that inhaling the scent of lavender oil significantly reduces anxiety before exams, surgery and dental procedures (185-190).

And in two studies of women with postpartum depression, inhalation of lavender oil significantly decreased their anxiety and stress (191-192).

Unlike a lot of other natural compounds, scientists actually understand how lavender works – it decreases heart rate, blood pressure, body temperature and sweating; and it increases heart-rate variability and alpha brain waves (193-198).

Animal research also shows that it reduces anxiety in rats by increasing GABA (199-204).

As a result of all this, it has a powerful sedative effect on the nervous system, decreases the fight-or-flight responses, and relaxes the body.

Lavender essential oil can be taken orally, inhaled or applied to your skin.

Silexan is an oral lavander oil capsule commonly used in studies.

25. 5-Hydroxytryptophan (5-HTP)

5-Hydroxytryptophan (5-HTP) is a naturally-occurring amino acid and the precursor to serotonin, a neurotransmitter that can reduce stress and anxiety.

It easily crosses the blood-brain barrier and effectively increases the synthesis of serotonin in the brain (205).

Research shows that supplementing with 5-HTP significantly reduces anxiety by increasing serotonin levels (206-208, 212).

One study found that people with panic disorder who take 5-HTP experience a reduction in panic and the fewer panic attacks (209).

Not only does 5-HTP reduce anxiety by increasing serotonin; it’s also been shown to promote relaxation by increasing GABA and BDNF levels (210-211).

5-HTP in supplement form is extracted from the plant Griffonia simplicifolia.

26. Black Seed Oil

Nigella sativa, more commonly known as Black Cumin Seed, has been used as a natural remedy for more than 2000 years.

It’s surprising more people haven’t heard of it because it’s actually one of the top-ranked evidence-based herbal medicines.

Researchers have found that black seed oil reduces inflammation and anxiety without side effects (218-219).

Studies also show that it significantly reduces anxiety-like behaviour in animals by increasing GABA and serotonin levels (220-224).

27. Skullcap

Skullcap refers to two separate medicinal herbs – American skullcap (Scutellaria lateriflora) and Chinese skullcap (Scutellaria baicallensis).

Both herbs have been shown to reduce anxiety and stress.

A double blind, placebo-controlled study demonstrated that American skullcap can reduce anxiety in adults (225).

Other research has found that Chinese skullcap can reduce anxiety and treat stress-related disorders by reducing stress hormones and enhancing GABA receptor activity (226-228).

28. Gotu Kola

Gotu Kola (Centella Asiatica) is an herb with antioxidant and anti-inflammatory properties.

It has been used for centuries in Ayurvedic and traditional Chinese medicine to alleviate symptoms of anxiety.

Researchers have found that Gotu Kola significantly reduces anxiety, stress and depression in individuals with generalized anxiety disorder (229).

In one study, people that supplemented with Gotu Kola were less likely to be anxious and easily startled (230).

Animal research shows that lowers anxiety-like behaviour in rats by increasing GABA levels (231-233).

It's important to point out that the Gotu Kola plant soaks up heavy metals from the soil. So you need to find a high-quality, organic source that doesn’t contain heavy metals.

Bringing It All Together: Taking Them in Combination Is Better Than Individually

It’s important to note that taking a combination of the above options will provide the greatest relief from anxiety.

They have a synergistic effect, meaning they work better when taken together.

Here are a bunch of proven combinations that you should consider if you want to powerfully reduce your anxiety and stress:

• Ashwagandha and Bacopa – In one study, researchers found that taking these herbs together worked significantly better than taking them alone (269).

• Bacopa and Omega-3 Fatty Acids – Since Bacopa is fat soluble, it’s said that it works better when it’s taken with a meal that contains fat. And research backs this up. One study found that bacopa and fish oil are more therapeutic together (270).

• Valerian and Lemon Balm – These two herbs are most often sold in combination with each other. And there’s good reasons why. Together, both of these plants significantly reduce anxiety, restlessness, concentration difficulties and impulsiveness in adults and children (272-273). Their both included in the Optimal Calm supplement.

• Chamomile and Lavender – One study showed that the aroma of both chamomile and lavender was more effective at reducing symptoms of anxiety and stress than either of them alone (271).

• L-Lysine and L-Arginine – These two amino acids aren’t even included in the list above because they aren’t effective at reducing anxiety and stress alone. But together, they have been shown to significantly reduce anxiety and decrease cortisol levels (274).

• A lozenge containing 4 different herbal preparations (lavender oil, extracts from hops, lemon balm and oat) has been shown to reduce anxiety, increase relaxation and increase alpha brain waves (275).

If you’re looking for an all-in-one supplement, this anti-anxiety supplement includes several of the natural compounds listed above all in one capsule.

20 Nutrient Deficiencies Proven to Cause Depression

Being depressed doesn’t mean you’re weak.

It’s not a defect in your personality. 

As I’m sure you know, it’s often caused by physiological changes in your body and brain.

So you need to think of it like any other illness. 

If you have a broken bone, you need to wear a cast to stabilize the bone while it heals. 

And if you have depression, you need to be kind to yourself, as you seek and address the underlying root causes. 

The good news is that you’re not powerless. 

I used to think that I’d be depressed forever.

That my depression was simply genetic, and I couldn’t do anything about it. 

In fact, I accepted that notion for a while.

I felt defeated and hopeless, and thought I'd feel that way for my entire life.

I told myself I’d simply have to rely on drugs to survive because that’s just “how I’m wired”. 

But then one day, I changed my mind and decided that I’d had enough. 

And I was actually going to get to the bottom of it instead of just accepting it.

I took action and searched far and wide for safer and healthier solutions to deal with my depression.

I came across a lot of different research and therapies.

I wasn’t sure if they would work, but then they did.

And I overcome my depression for good. 

One of my most important discoveries was that nutrient deficiencies can make your depression worse. 

And they could even be the root cause of it. 

It made so much sense.

But why hadn’t anyone ever brought it up?

I delved deeper into the scientific literature, and I found MANY nutrient deficiencies that can contribute to depression.

I started increasing my intake of them.

And I got better.

Much better.

This new post includes 20 nutrient deficiencies that could be making you feel depressed.

Read on to learn more. 

Vitamin Deficiencies That Can Cause Depression

1. Vitamin B12

“Lack of understanding of B12 is one of the greatest tragedies of modern medicine.”

— Dr. James Greenblatt, Integrative Psychiatrist

Having sufficient levels of Vitamin B12 is necessary for optimal brain and mental health.  

Unfortunately, a deficiency is very common, especially in older individuals and vegetarians and vegans.

And even if you eat meat and you’re young, you may still have a deficiency. 

Poor gut health and even psychiatric medications can cause a deficiency.

In fact, it’s estimated that almost 40% of Americans are deficient today.

Numerous studies have shown that having a deficiency in Vitamin B12 leads to symptoms of depression (16-22). 

And B12 levels tend to be significantly lower in people who are depressed (13). 

In one study, subjects with Vitamin B12 deficiency were 2 times as likely to be severely depressed as non-deficient subjects (15). 

Even a mild decrease in B12 levels is associated with mood disturbances (14). 

Luckily, there are steps you can take if you’re deficient. 

Vitamin B12 is found primarily in animal foods, and beef liver is an excellent source. I take beef liver capsules because I don’t like the taste of liver.

You may also want to supplement with Vitamin B12 because studies show that B12 supplementation significantly lowers homocysteine levels and reduces depressive symptoms (23-24). 

If you decide to supplement, avoid the semisynthetic version of B12 (cyanocobalamin) and instead take the methylated form (methylcobalamin or methyl-B12). 

Methyl-B12 is better absorbed and more biologically active.

2. Vitamin D (and Vitamin K2)

Vitamin D is a fat-soluble vitamin that your skin synthesizes when exposed to the sun.

Every tissue in your body has Vitamin D receptors, including the brain, so a deficiency can lead to costly physiological and psychological consequences, including depression.

Researchers have found a very strong link between Vitamin D deficiency and depression (27-28). 

The lower your Vitamin D levels, the more symptoms of depression you are likely to have (35). 

Unfortunately, reports indicate that Vitamin D deficiency is widespread and a major health problem globally (25). 

Researchers estimate that 50 percent of the general population is at risk of Vitamin D deficiency (26). 

It’s best to get your Vitamin D by going outside and getting sunlight.

It’s especially important to make sure you get some sunlight in the morning to set your circadian rhythm. 

But most people still don’t get enough Vitamin D from the sun, especially during the winter.

That’s why I recommend taking a Vitamin D supplement. 

Research does show that taking a Vitamin D3 supplement is effective at reducing symptoms of depression and seasonal affective disorder (29-31). 

This is likely because Vitamin D increases the production of numerous neurotransmitters, including serotonin, dopamine, norepinephrine and epinephrine (32-34). 

It's important to test and monitor your Vitamin D levels before and after supplementing with it.

Lastly, if you decide to supplement with Vitamin D3, you should consider taking it with Vitamin K2. 

A recent study found that Vitamin K2 reduces depression in animals (36). 

And Vitamin K2 is known to improve brain function in humans (37-38). 

3. Vitamin B6

Having a deficiency in Vitamin B6 can also contribute to your depression.

It’s a key nutrient that supports your entire nervous system.

It can boost your mood because it plays a key role in the production of neurotransmitters in your brain, including serotonin and dopamine. It also lowers homocysteine. 

Research shows that people with depressive symptoms tend to have low levels of Vitamin B6 (85-87). 

A Vitamin B6 deficiency also contributes to chronic inflammation, which is one of the main underlying root causes of depression (88). 

Fortunately, consuming more Vitamin B6 can help. 

One study found that women that eat more foods containing Vitamin B6 have a lower risk of depression (89). 

Some of the best food sources of Vitamin B6 include potatoes, bananas and chicken. 

But supplementation is often necessary to see quick improvements. 

One study found that supplementing with Vitamin B6 can reduce depressive symptoms by lowering homocysteine levels (90). 

When I took antidepressants for depression, multiple functional and integrative doctors suggested I supplement with Vitamin B6.

This is because these medications can actually further deplete Vitamin B6, increasing depression in the long run. 

Vitamin B6 is included in the Optimal Zinc supplement.

4. Vitamin C

Having low levels of Vitamin C can also make you feel depressed.

Researchers have found that poor Vitamin C status is associated with increased symptoms of depression (105). 

Animal research also shows that a Vitamin C deficiency can lead to low levels of dopamine and serotonin in the brain, which causes mice to act depressed (106-107). 

As you probably know, Vitamin C can be found in foods such as peppers, citrus fruits, green leafy vegetables, broccoli, tomatoes, and berries. These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

In addition to getting Vitamin C from fruits and vegetables, I take at least 500 grams of this Vitamin C every day. 

I’ve experimented with taking up to 10 grams daily, and it definitely improved my mood and reduced my stress levels, especially when I was coming off antidepressants. 

Research backs this up, showing that supplementing with Vitamin C can actually improve mood in both unhealthy and healthy individuals (95, 102-103). 

Various other studies show that Vitamin C supplements reduce stress and anxiety and decrease the severity of depression (96-101, 104).

Studies even show that Vitamin C can increase the effectiveness of antidepressants (108-109). 

5. Folate

Folate (Vitamin B9) is an essential B vitamin that plays a key role in methylation, one of the most important processes in your body and brain for optimal energy and nervous system function.

Researchers have found that if you are depressed, you likely have lower levels of folate circulating in your blood, and people with low blood folate are at greater risk for developing depression (55-56). 

Good dietary sources of natural folate include: 

• Leafy greens

• Asparagus

• Broccoli

• Cauliflower

• Strawberries

• Avocado

• Beef liver

• Poultry

These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

However, eating folate-rich foods sometimes isn’t enough. In fact, many people do not get enough folate from food because cooking and food processing destroy natural folates (54).

And supplementation is often needed. 

In one study, patients with depression took methylfolate for 6 months, and they witnessed a significant improvement in their depressive symptoms (57). 

Researchers have even suggested that folate supplementation should be a first-line treatment for depression (58). 

Methylfolate can be effective at treating depression because it helps lower homocysteine levels, helps produce serotonin and dopamine, and stimulates serotonin receptors in the brain (59-62). 

6. Thiamine

Thiamine, also known as Vitamin B1, is an essential water-soluble nutrient that cannot be made by the body. 

It’s used in nearly every cell in the body and especially important for supporting energy levels.

It’s also required by nerve cells and other supporting cells in the nervous system (167). 

Research shows that lower levels of Vitamin B1 are associated with a higher prevalence of depressive symptoms (168).

Vitamin B1 deficiency is also known to lead to irritability and symptoms of depression (170). 

Some doctors and researchers believe that postpartum depression is sometimes simply a Vitamin B1 deficiency (169). 

Luckily, consuming more Vitamin B1 can help.

A randomized, double-blind clinical trial found that Vitamin B1 supplementation reduces symptoms of depression within 6 weeks (171). 

And another concluded that Vitamin B1 supplementation improves mood, reduces brain fog, and speeds up reaction time (172).

In fact, researchers have even found that subjects’ mood improves if the amount of Vitamin B1 in their blood increases, and that the opposite occurs if the amount of Vitamin B1 in their blood decreases (173). 

Healthy food sources of Vitamin B1 include green peas, beef liver, asparagus, pecans, spinach, sunflower seeds, macadamia nuts, oranges, cantaloupe and eggs. 

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

7. Riboflavin

Riboflavin, also known as Vitamin B2, plays a key role in energy metabolism throughout your entire body.  

As a result, a Vitamin B2 deficiency can affect the entire body, leading to low energy, weight gain, and depression.

In fact, lower levels of Vitamin B2 have been found in people with depression (91). 

Researchers have also found that Vitamin B2 consumption decreases risk of postpartum depression (92). 

Healthy food sources of Vitamin B2 include pastured eggs, leafy vegetables, beef liver, mushrooms, sunflower seeds, and almonds. 

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

If you’d like, you can also supplement with Vitamin B2.

Studies show that supplementing with Vitamin B2 helps lower homocysteine and reduces depressive symptoms (93-94). 

Vitamin B2 is included in the Optimal Zinc supplement. 

8. Inositol

Inositol is a naturally-occurring molecule found in nearly all plants and animals. It plays a key role in various biological processes.

The brain has the highest concentration of inositol, where it plays an important role making neurotransmitters (124). 

Inositol can be found in many foods, particularly fruit, especially cantaloupe and oranges (125). 

It used to be considered a B Vitamin, called Vitamin B8. But it currently is no longer considered an essential nutrient because your body can produce inositol from glucose (126). 

But I’m including it in this list anyway because individuals with depression have very low levels of inositol in their brains (127-129). 

And inositol supplementation has been shown to increase inositol levels and help treat depression (130, 132). 

It can also reduce symptoms of depression in women with premenstrual syndrome and premenstrual dysphoric disorder (131, 133). 

It’s even been shown to help patients who have discontinued their antidepressant medication (134). 

I took high doses of inositol powder when weening off psychiatric medication.

Check out my full post about inositol to learn more about the benefits. 

Fun fact: Inositol is also used as a stand-in for cocaine in television shows and movies. 

9. Coenzyme Q10

Coenzyme Q10 (CoQ10) is a coenzyme and antioxidant located primarily in the mitochondria. It has numerous known health benefits and plays a critical role in producing energy for the body.

CoQ10 is produced within the body, but it’s also found within food and can be supplied to the body through food or supplementation. It resembles a fat-soluble vitamin.

Meat and fish are the richest sources of dietary CoQ10, including beef, pork, chicken heart, and chicken liver. Nuts and some oils also contain some CoQ10 (110). 

Research shows that CoQ10 levels are reduced in people with depression and chronic fatigue (111). 

One study also found that CoQ10 regulates serotonin levels and depressive symptoms in fibromyalgia patients (117). 

CoQ10 supplementation has also been shown to improve fatigue and reduce depression symptom severity (112-114). 

It also displays antidepressant-like activity in animals (115-116). 

Mineral Deficiencies That Can Cause Depression

10. Magnesium

Magnesium is a vital mineral that participates in more than 300 biochemical reactions in your body.

Unfortunately, a lot of people are deficient in magnesium today.  

This is a shame because magnesium is absolutely essential for the proper functioning of your nervous system and optimal neurotransmitter activity. 

Research shows that low magnesium levels contribute and worsen many neuropsychiatric problems, including depression (42). 

In fact, researchers have found that people with depression have lower magnesium levels than healthy people (49). 

They’ve also found a significant association between very low magnesium intake and depression (43). 

On top of this, animal research shows that removing magnesium from their diet results in depressive-like symptoms (50). 

So if you’re struggling with depression, it’s very important to make sure you’re getting enough magnesium so that you don’t have a deficiency.

Luckily, there are a number of ways to do this. 

First, make sure you’re eating magnesium-rich foods on a regular basis, including:

• Spinach

• Chard

• Pumpkin seeds

• Almonds

• Avocado

• Dark chocolate

• Bananas

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

Epsom salt baths are another great way to increase your body’s intake of magnesium. 

I also highly recommend a high-quality supplement that includes magnesium.

Magnesium is included in this supplement.

A number of studies have concluded that magnesium supplementation can reduce depressive symptoms in humans – sometimes within 7 days (44-48). 

Since most people are deficient, magnesium is one of the three supplements that I think everyone should be taking.

11. Zinc

Zinc is an essential mineral for mental health.

Like magnesium, it plays a key role in neurotransmission and nervous system functioning.

Mounting evidence suggests a link between zinc deficiency and the development and severity of depression (66-68, 76).  

Depressed patients tend to have lower levels of zinc. And as their zinc levels drop, their depressive symptoms get worse (81-84). 

Unfortunately, it’s estimated that 2 billion people in the world are deficient in zinc, and several studies show that even subclinical deficiency of zinc impairs brain function in children and adults (63-65). 

So, if you struggle with depression, it’s quite possible that you’re deficient, and you’ll definitely want to optimize your zinc levels. 

Some of the best food sources of zinc include:

• Oysters

• Grass-fed beef

• Pumpkin seeds

• Cashews

• Mushrooms

• Spinach

These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

However, if you’re deficient like I was, I recommend taking a high-quality zinc supplement, at least for a short period of time. 

A meta-analysis and several studies have concluded that zinc supplementation has antidepressant effects and significantly reduces symptoms of depression. One way it improves mood is by significantly increasing BDNF levels (69-75, 77-80).

I created and take the Optimal Zinc supplement to make sure my zinc levels are optimal. 

Check out my previous post all about zinc if you’re interested in discovering more steps you can take to increase your zinc levels.

12. Iron

Iron is a trace mineral found in every living cell in our bodies.

It carries oxygen to all parts of your body, and low levels can leave you feeling tired, pale, irritable and foggy. 

Sounds like depression doesn’t it?

Several studies show that iron deficiency increases the risk of developing depression and increases the severity of depression (184-186, 188-190). 

Researchers have also conducted a meta-analysis and found that high iron intake reduces the chance of developing depression (183). 

In one study, iron supplementation resulted in a 25% improvement in depressive symptoms (187). 

Despite this, I don’t actually recommend supplementing with iron though because some research suggests that too much iron can cause health problems.

It’s definitely preferable to get your iron from food. 

I make sure I get enough iron simply by taking grass-fed beef liver capsules.

Beef liver is one of the best sources of iron, but I don’t like the taste, so I go with the capsules.

Other good sources of iron include:

• Spirulina

• Dark chocolate

• Spinach

• Sardines

• Pistachios

• Raisons

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

13. Selenium

Selenium is an essential trace mineral that is important for many bodily processes that affect your brain and mental health.

Researchers have found that depression is associated with low levels of selenium (191). 

But supplementing with selenium has been shown to significantly increase selenium levels and improve symptoms of depression (192). 

Other research shows that selenium intake is associated with a general elevation of mood (193). 

Brazil nuts are the richest dietary source of selenium, but it can also be found in wild-caught seafood, pastured chicken and eggs, and grass-fed meat.

I also make sure I’m not deficiency in selenium by supplementing with it.

Selenium is included in this supplement.

14. Manganese

Manganese is an important trace mineral for human health. It acts as a cofactor, helping many enzymes carry out their functions in the body.

Research shows that having low levels of manganese can contribute to the development of depression (135). 

One study found that depressed patients had significantly lower levels of “manganese superoxide dismutase”, which is a manganese-dependent enzyme (136). 

Researchers have also found that women with higher manganese intake had a lower prevalence of depressive symptoms (137). 

Hazelnuts and macadamia nuts contain high levels of manganese, while leafy green vegetables, tea, chocolate and some fruits contain moderate levels (139). 

However, it’s important to note that you shouldn’t consume too much manganese.

In excess, manganese is neurotoxic and can lead to manganism, a neurodegenerative disorder that causes dopaminergic neuronal death and symptoms similar to Parkinson's disease (138). 

So I definitely don’t recommend supplementing with large doses of manganese. 

The small amount of manganese in Optimal Antiox is fine though. It’s what I take. 

Fatty Acid Deficiencies That Can Cause Depression

15. Dihomo-Gamma-Linolenic Acid

Dihomo-Gamma-Linolenic Acid (DGLA) is an uncommon fatty acid.

It’s made in the body by the elongation of Gamma Linolenic Acid (GLA).

But small amounts can also be found in animal products (118). 

Last year, researchers found that people with depression are more likely to have low levels of DGLA levels (121). 

And increasing DGLA levels may lower the risk of developing depression (122). 

DGLA also has anti-inflammatory effects in the body (119). 

So it makes sense that levels would be low in depressed individuals because an increasing amount of evidence suggests that depression is a chronic inflammatory disease. 

DGLA can be increased by supplementing with dietary GLA (120). 

GLA can be found in Borage Oil, Evening Primrose Oil and Blackcurrant Seed Oil (123). 

16. Omega-3 Fatty Acids

Omega-3s fatty acids are the highest quality fats for the brain and increasing your intake of them is one of the most impactful actions you can take to fight depression.

Several studies have shown that depressive patients have lower levels of omega-3 fatty acids (1-3).

Researchers even conducted a meta-analysis of 14 studies, and they found that levels of omega-3 fatty acids were significantly lower in people with depression (4). 

They concluded that having a deficiency in omega-3 fatty acids is a “contributing factor to mood disorders” (5). 

It’s important to consume enough omega-3 fatty acids because they are essential fats that your body cannot produce itself.

Omega-3 fatty acids are found primarily in cold water fish, including:

• Salmon

• Black cod

• Sablefish

• Sardines

• Herring

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

Unfortunately, most people don't consume enough omega-3 fatty acids through their diet.

That’s why I recommend supplementing with krill oil, a special kind of fish oil that contains the essential omega-3 fatty acids. 

Plenty of research shows that omega-3 supplements are effective at treating clinical depression – just as effective as antidepressants drugs – because they lower inflammation in the brain (6-10). 

Amino Acid Deficiencies That Can Cause Depression

17. Carnitine

Carnitine is an amino acid found in nearly every cell of the body. It plays a vital role in the production of energy.

Researchers have found significantly lower levels of carnitine in patients with depression. And their low carnitine levels are associated with the severity of their depression (11-12, 174-175). 

Carnitine is mainly found in meat, fish and poultry.

But you can also supplement with it. 

I recommend Acetyl-L-Carnitine (ALCAR), an acetylated form of carnitine. It’s best supplemental form of carnitine. 

It’s often used as a natural brain booster because it increases alertness and provides support to brain cells.

But it’s also been shown to be very effective at quickly improving mood and treating depression (179-182). 

Six randomized clinical trials have demonstrated that ALCAR is better at treating depression than placebo (177). 

And two other studies found that ALCAR improved depressive symptoms in patients with chronic depression, and it was just as effective as antidepressant medications, but with less side effects (176, 178). 

ALCAR is included in the Optimal Brain supplement. 

Make sure you read this article to learn more about the remarkable benefits of ALCAR.

18. Glutamine

Glutamine is the most abundant amino acid in the body, suggesting that it’s very important.

It’s also one of the few amino acids that can directly cross the blood-brain barrier.

Glutamine is a conditionally essential amino acid, meaning the body can usually produce sufficient amounts of it. But sometimes the body uses up so much glutamine that it becomes necessary to obtain it from the diet or supplements, particularly during periods of illness, stress, inflammation and injuries (156-157). 

Researchers have found that depressed adults have reduced levels of glutamine (158). 

And glutamine deficiency has been shown to increase depressive-like behaviour in animals (159). 

But glutamine supplementation has “clear anti-depressive properties” and has been shown to improve mood (160-161). 

High levels of glutamine can be found in protein-rich foods such as beef, chicken, fish and eggs. Beets, cabbage, spinach, carrots, parsley, brussel sprouts, celery, kale and fermented foods like miso also contain some glutamine.

These foods are included in my Free Grocery Shopping Guide for Optimal Mental Health.

Glutamine is also available in supplement form. 

Glutamine was one of the main supplements that helped me heal my leaky gut, but I no longer need to take it regularly. 

19. Tryptophan

Tryptophan is an essential amino acid that cannot be produced by the body. It must be consumed through diet or by taking supplements. 

Some healthy foods that contain tryptophan include bananas, chicken, turkey and dark chocolate (140). 

Tryptophan helps produce the neurotransmitter serotonin. It’s converted to 5-hydroxytryptophan (5-HTP) in the brain, which then produces serotonin (141-142). 

Researchers have found that depressed patients have significantly lower levels of tryptophan in their blood than healthy control subjects (143-144). 

Studies also show that depressed patients have a decreased ratio of tryptophan to neutral amino acids in their blood. This suggests that tryptophan availability to the brain is likely reduced in depressed patients (145-146). 

Personally, supplementing with tryptophan never helped me. In fact, it always seemed to make me worse. It gave me asthma and acne and increased my depression.  

This is because depressed patients sometimes have problems creating serotonin from tryptophan. Instead, they create other metabolites from tryptophan, such as quinolinic acid, which can be toxic. For depressed patients like me, tryptophan supplementation won’t help, and may actually make their depression worse (150-151). 

However, some people do see their mood improve when they increase their intake of tryptophan. So it shouldn’t be completely disregarded. 

There are studies that show that consuming a high tryptophan diet and consuming additional dietary tryptophan can increase mood and lead to significantly less depressive symptoms (152-154). 

So supplementing with tryptophan is worth a shot if you’re struggling with depression and haven’t tried it yet. Just be aware of possible side effects. 

If you want, you can also try supplementing with 5-HTP instead of tryptophan. 5-HTP is the direct precursor to serotonin. 

5-HTP is included in this supplement. 

20. Glutathione

Glutathione is a small peptide made up of 3 important amino acids – glutamic acid, cysteine and glycine – each of which have several important roles in the human body.

Glutathione is found in the food supply and within the human body, where it acts as an antioxidant. It is used by every cell in the body.

It’s technically not an “essential nutrient” because the body can create it.

However, it’s still very important, and a glutathione deficiency leads to increased susceptibility to oxidative stress, which is thought to be involved in a number of diseases, including depression.

Studies show that patients with depression have significantly lower levels of glutathione. And the lower a person’s glutathione levels, the more depressed they are likely to be (162-164). 

Some practitioners and researchers have found that increasing glutathione intake and levels can successfully treat depression (165). 

Glutathione is also able to prevent behavioural depression in animals (166). 

It’s important to note that standard glutathione supplements are not very effective at increasing glutathione levels because they are not well absorbed by the body.

N-acetyl-cysteine (NAC) is a tried-and-true way of increasing glutathione levels because it’s the direct precursor to glutathione. 

Garlic, asparagus, and cruciferous vegetables, such as broccoli and kale, can also help boost glutathione levels, but NAC supplements are more powerful. 

Other supplements that have been shown to help increase and maintain optimal glutathione levels include Selenium, Alpha Lipoic Acid, and S-adenosyl-methionine (Sam-E).

How to Protect Your Brain from Blue Light

Overcoming brain and mental health issues isn't just about nutrition and supplementation. 

It's also about light.

Chronic exposure to artificial blue light is a risk factor that is often overlooked. 

This post talks about how you should be striving to reduce your blue light exposure as much as possible throughout the entire day (unless it’s naturally coming from the sun). 

We're getting way too much blue light nowadays, and it’s taking a toll on your brain and mental health. 

And if you’re interested in learning more about light, I recommend the book Light: Medicine of the Future by Dr. Jacob Liberman. 

What Is Blue Light?

Light is part of the electromagnetic spectrum. 

Our eyes can only see light that falls within a small range of the electromagnetic spectrum, called "visible light". The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum. 

Visible light corresponds to a wavelength range of approximately 400 to 700 nanometers (nm). Each visible wavelength is represented by a colour. Blue light is defined as having a wavelength between 450 and 495 nm. This short wavelength means that blue light is a type of high-energy visible light (25). 

Blue light is emitted from energy-efficient fluorescent and LED bulbs, and electronics such as computers, smartphones, tablets, and televisions. Obviously, these indoor man-made sources of blue light are on the rise, and we’re being exposed to more blue light in our environments than ever before (26). 

Why Artificial Blue Light Is Bad for Your Brain and Mental Health

I’ve been learning more and more that it’s best to limit your exposure to artificial blue light all day long, and not just at night. 

It’s important to note that there’s a big difference between artificial blue light and natural blue light from the sun. 

During the day, exposure to full-spectrum sunlight – which naturally contains some blue light –is actually beneficial and necessary for resetting your circadian rhythm.

The blue light from the sun is also balanced with other colours of light, such as red, green, infrared, and ultraviolet light.

But our devices and artificial lights have five times the amount of blue light than you would get from the sun. 

In the past, our ancestors would have been exposed to blue light from the sun only, and they weren’t exposed to blue light at night. 

But today, we shield ourselves from full-spectrum natural sunlight, and live indoors with excess artificial blue lighting all day long. 

And this is having brain and mental health consequences.

What The Experts Are Saying

An increasing number of researchers, doctors and health organizations are speaking out about this. 

Dr. Jack Kruse, MD, a neurosurgeon and author of the book Epi-Paleo Rx, and speaks passionately about the risks of blue light. He argues that attending to your light environment is more important than food. 

Dr. Alexander Wunsch, another physician and researcher in the field of photobiology, explains that artificial LED lights have an excess of blue light, and not enough red light, and this creates reactive oxygen species (19):

“We don’t have this kind of light quality in nature. This has consequences. The stress has consequences in the retina; it has consequences in our endocrine system.”

— Dr. Alexander Wunsch

Even the American Medical Association is speaking out about this issue.  Last June, they released guidelines on how to reduce the harmful human and environmental effects of high-intensity LED lighting.

They point out that the energy-efficient LED lighting adversely suppresses melatonin at night, has a “five times greater impact” on sleep rhythms than conventional lighting, and widespread implementation of this lighting will lead to sleep problems and other conditions related to poor sleep.

“Despite the energy efficiency benefits, some LED lights are harmful.”

— Dr. Maya A. Babu, AMA Board Member

There is lots of research to support these claims and concerns. 

Researchers have discovered photoreceptors (light-sensitive cells) in our eyes that track the amount of blue light we're exposed to throughout the day. These photoreceptors communicate with areas of your brain that affect your mood, emotions and circadian rhythm (20-22). 

It’s also well-established that blue light at night sends a signal to your body that it’s daytime, which increases the amount of time it takes to fall asleep and reduces the quality of your sleep. It does this by significantly suppressing the production of melatonin, your body’s sleep hormone (27-34).

Melatonin is also an antioxidant that protects your brain and increases mitochondrial function. So chronically low melatonin can lead to lower mental energy and neurodegeneration (35-37). 

In my experience, if your circadian rhythm is thrown off and you’re not sleeping well, it's very hard to be completely healthy and emotionally balanced.

Studies show that exposure to blue light at night is significantly associated with depression (23). 

Other research has found that “higher nighttime light intensity” leads to lower melatonin levels, which contributes to depression and cognitive impairment (24). 

But luckily there are ways to protect yourself.

Let’s get into what you can do to shield yourself from the negative effects of artificial blue light. 

1. Use Software That Blocks Blue Light

Installing software that prevents blue light from being emitted from your technology is another cheap and straightforward action you can take to protect yourself from excess blue light.

My number one recommendation is to install the program Iris on your computer. You can download it here. 

Iris automatically alters the colour temperature of your screen as the day goes on, removing the blue wavelengths after sunset.

The standard setting only removes blue light in the evening, but you can change the settings so that it blocks out blue light all day long. That’s what I do now. 

Iris takes care of your computer, but what about your phone? 

Last year, Apple released Night Shift with its iOS 9.3 update to reduce the amount of blue light emitted from the iPhone. You can learn how to activate this on your iPhone here. I have Night Shift turned on all throughout the day. 

You can also install Twilight if you have an Android device.

2. Wear Blue-Light-Blocking Glasses

It's becoming increasing clear that one of the simplest and least expensive ways to support your brain, promote healthy sleep, and lower your risk of chronic mental disease, is to wear blue-light-blocking glasses not just at night, but anytime you are exposed to artificial lighting.

I own multiple pairs of blue-light-blocking glasses myself.  

Research shows that wearing blue-light-blocking glasses improves sleep quality and mood (1). 

Other studies show that wearing blue-light-blocking glasses in a bright room or while using blue-lit technology maintains normal melatonin levels at night (2-4). 

Researchers have also found dramatic improvements in insomnia and mood in about half of bipolar patients who wore blue-blocking glasses (5). 

People with bipolar disorder who wore blue-blocking glasses from 6 p.m. to 8 a.m. for seven days had significant improvements in symptoms of mania compared to those who wore clear glasses. These benefits kicked in after just 3 days (6-7). 

I used to work on a computer in an office with lots of artificial fluorescent lighting shining down on me. 

At that time, I would wear these Gunnar computer glasses. These glasses have a light-yellow tint and are somewhat stylish. They significantly reduced the amount of blue light that I was exposed to throughout the day, which reduced fatigue and eye strain. 

They are like the opposite of sunglasses - I wore them inside when I was exposed to artificial blue light, and took them off when I went outside.

Gunnar Optiks has a wide-range of computer and gaming glasses to choose from through Amazon. 

If you work under blue light all day, it’s also a good idea to wear long sleeves because your skin also absorbs the blue light. Shielding it from your eyes is the priority though.

At home in the evening, I wear these orange-tinted Uvex glasses as soon as it’s dark outside. They eliminate all blue light, but aren’t stylish at all, so you’re better off wearing them inside and not out in public.

I also just ordered these red glasses, as they block out both blue and green light. Green light has been shown to stunt the release of melatonin, but not nearly as much as blue light. If you don’t have blue-blocking glasses yet, get the red ones. 

You can also get BluTech prescription lenses for the daytime but I haven’t done that for myself yet.

3. Increase Your Exposure to Red and Infrared Light

“Blue light causes reactive oxygen species in your tissue, and this stress needs to be balanced with near-infrared light that is not present in LEDs.”

— Dr. Alexander Wunsch

If you’re exposed to too much blue light, you need to make up for it later by exposing yourself to more red light.

One of the reasons red and infrared light supports brain and mental health is because it combats the effects of blue light. 

Ideally, we would simply be exposed to the sunlight throughout the day, which has a healthy balance of both blue and red light.

But unfortunately, we live in the modern world, and it’s not possible to live outside all day like our ancestors, even though our bodies still expect us to. 

I work in an office environment with lots of blue light, and no red and infrared light.

So to balance out my excess blue light exposure during the day, I use a number of different LED devices and bulbs in the evening that emit red and infrared light. 

As I’ve discussed before, I use this device on my head and thyroid. It has LEDs that emit red and infrared light. 

But what I haven’t mentioned before is that I also have this infrared bulb shining in my bedroom and this red bulb in my bathroom. I use them to light up my apartment, particularly at night.

Infrared saunas are another excellent way to expose yourself to infrared light. Check out my post about the benefits here. 

“Penetrating red light is possibly the fundamental anti-stress factor for all organisms. Old observations such as Warburg’s, that visible light can restore the activity of respiratory pigments, showed without doubt that visible light is biochemically active. By the 1960s, several studies had been published showing the inhibition of respiratory enzymes by blue light, and their activation by red light. The problem to be explained is why the science culture simply couldn’t accept crucial facts of that sort.”

— Dr. Raymond Peat

I find that doing all of this increases my energy and mood.

This may all seem strange but it works, and there is plenty of evidence to support it. 

In fact, red light therapy has been around for over 100 years. In 1910, Dr. John Kellogg published a book, titled Light Therapeutics, in which he recommended light therapy for a number of different diseases, including chronic fatigue.

Research shows that high-intensity blue light is bad for your mitochondria, while red light enhances mitochondrial function (15-18). 

I even found a study that clearly shows that red LED light protects animals from fake artificial blue light (14). 

And here is a spreadsheet that compiles a lot of the research showing that red and infrared light can help treat many different diseases, including depression, anxiety, traumatic brain injury, stroke, Parkinson's disease, Alzheimer's disease, multiple sclerosis, hypothyroidism, acne and chronic pain. 

Overall, blue light triggers oxidative stress in your cells, while red light repairs and regenerates your cells. Blue light is the equivalent to eating junk food, while red light is like eating healthy food. Staring at your smartphone all day and night is like eating McDonalds, while shining red light on yourself is like eating more vegetables. If you eat too much junk food, you might make up for it later by eating healthier and exercising. But with blue light, you need to make up for it by absorbing more red light. That’s what I do, and I hope it helps you too. 

4. Sleep in a pitch black room

Making sure your bedroom is as dark as possible while you sleep is another step you can take.  

Light can penetrate your eyelids, so simply closing your eyes is not enough. 

Even small amounts of light can reduce your melatonin production and disrupt your circadian rhythm. Exposure to room light during sleep has been shown to suppress melatonin by more than 50 percent (8). 

I completely black out my room with black-out curtains.

Another option is to wear a sleep mask. 

However, it’s important to note that your skin also has photreceptors and can sense light in your environment (9-11). 

So it’s optimal to just black out your entire room with curtains, especially if you have LED streetlights outside your house. 

Electronics should also be unplugged so that your room is completely dark. 

If you do these things, you’ll notice a profound difference in your sleep and brain and mental health.

5. Vitamin E and N-Acetyl-Cysteine (NAC)

Vitamin E and N-Acetyl-Cysteine (NAC) are two nutrients with antioxidant effects. 

One study found that NAC protects against the cellular damage induced by blue LED light (38). 

Perhaps this is one of the reasons NAC helps people who struggle with mental illness. 

Another study found that a combination of vitamin E and NAC significantly reduced blue-light-induced levels of reactive oxygen species (39). 

Both NAC and Vitamin E are included in the Optimal Antiox supplement.

6. Lutein and Zeaxanthin

Lutein and zeaxanthin are two more antioxidants that are found in your eye that may be able to protect you from the detrimental effects of blue light.  

Both zeaxanthin and lutein cannot be made by your body, so you must get them from food or supplements. They are found in green leafy vegetables, orange and yellow-coloured fruits and vegetables, and egg yolks. 

Together, these antioxidants can reduce free radicals before they cause damage and help your body better handle excess blue light. Researchers have found that they “absorb a broader spectrum of high-energy blue light, which offers greater protection of retinal tissue” (12, 13). 

You can also take them together as a supplement. 

Conclusion

Nutrition is important. But it's not the be all and end all.

Light is just as important.

Overall, you should aim to limit your exposure to blue light, both during the day and evening. 

Humans evolved getting a full spectrum of light throughout the day, not overwhelming amounts of artificial blue. 

Excessive blue light from LEDs and electronic screens can contribute to illness by triggering an overproduction of reactive oxygen species and decreasing your body’s production of melatonin.

But with the above modifications, you can significantly reduce the amount of blue light that enters your eyes and affects your brain and mental health.

How to Improve Your Brain Function with An Oxygen Concentrator

“Insufficient oxygen means insufficient biological energy that can result in anything from mild fatigue to life threatening disease. The link between insufficient oxygen and disease has now been firmly established.”

— Dr. W. Spencer Way, Journal of the American Association of Physicians

Oxygen is absolutely essential for life, and your brain depends it more than any other part of your body.

Your brain weighs about 2% of your body weight.

But it consumes about 20% of the oxygen you breathe.

Your brain cells need to get enough oxygen to produce energy and function optimally.

If they don’t, they can start to deteriorate, leading to poor memory and concentration, low mood, lack of energy and drive. 

I personally use oxygen therapy with an oxygen concentrator to support and optimize my brain function. 

This post discusses oxygen therapy, the benefits, how I use it, and how it could help you. 

It’s a great way to boost cognitive function, memory and energy.

Read on to learn more. 

Types of Oxygen Therapy

Oxygen therapy is the use of supplemental oxygen to treat a variety of medical conditions.

Air is typically 21% oxygen by volume, but oxygen therapy increases the amount.

Hyperbaric oxygen therapy (HBOT) is the most well-known type of oxygen therapy, and it allows patients to inhale 100% pure oxygen in a total body chamber.

HBOT is often used by professional athletes for recovery and performance.

But it’s expensive and not available to most people. 

Luckily, it’s not the only option available to you. 

Normobaric oxygen therapy (NBOT) is much less expensive, and it’s easily accessible and non-invasive. I personally use NBOT at home. 

Similar to HBOT, NBOT brings a higher percentage of oxygen into the body and can bring major benefits to your brain and cognition.

Researchers have found that both normobaric and hyperbaric oxygen therapy increase the amount of oxygen that is delivered to the blood and brain (1-2). 

With normobaric therapy, oxygen can be delivered via an oxygen concentrator. 

An oxygen concentrator is a machine that separates oxygen from room air, and then delivers the concentrated oxygen through a nasal cannula or mask.

I use this oxygen concentrator.

Make sure you read the “My Experience” section below where I discuss how to use it. .

Why You Might Need Oxygen Therapy and How It Works

Hypoxia is a condition in which the body or a region of the body is deprived of adequate oxygen supply.

If this happens to you, you can end up with mitochondria dysfunction and poor brain function. 

But how do you know?

You can use an oxygen saturation monitor to measure and monitor your blood oxygenation levels. I use this monitor. It’s the best and most accurate oxygen saturation monitor that is often used by medical professionals, and freely available to the public.

Your blood oxygen saturation levels (SpO2) should measure 99-100% if you want to feel optimal.  

There are a number of reasons why your body and brain might not be getting enough oxygen:

• Sedentary lifestyle and lack of exercise

• Shallow breathing – Most people today don’t breathe well and are shallow breathers.

• Chronic stress – Stress and anxiety can also affect your breathing. If you're stressed and anxious, you end up taking more shallow breaths. Your sympathetic “fight or flight” nervous system is chronically active, and this reduces the amount of oxygen that reaches your brain.

• Abnormal blood pressure – Both high and low blood pressure can be problematic and may suggest that blood is not optimally flowing to your brain. If blood flow to your brain is poor, oxygen levels in your brain will also be suboptimal.

Normobaric oxygen therapy can help you if you’re struggling with any of these problems.

It can also help if you’re recovering from a concussion or brain injury or some sort of toxic exposure (e.g. mold). 

Neuroplasticity and neurogenesis require oxygen, and increasing the delivery of oxygen to the body and brain supports the healing process of damaged tissue.

Normobaric oxygen therapy has been shown to work by increasing brain blood flow, reducing permeability of the blood-brain barrier, and it may even have cholinergic properties (3-8). 

Researchers have concluded that the “neuroprotective role of normobaric oxygen therapy is extremely promising” (9). 

They have also found that it can lead to a number of positive cognitive outcomes, which I'll explore below. 

1. Normobaric Oxygen Therapy Improves Memory and Recall

In their book Advances in Natural Medicines, Nutraceuticals, and Neurocognition, Dr. Andrew Scholey and Dr. Con Stough state that normobaric oxygen therapy is an effective memory enhancer: 

“Research has shown that oxygen administration leads to improved long-term memory compared to a control group of normal air-breathing.”

Several clinical studies also show that concentrated oxygen significantly enhances memory formation and recall in adults (10-11, 16-17). 

In one study, inhalation of oxygen immediately prior to learning a word list resulted in a significant increase in the average number of words recalled 10 minutes later (14). 

In other studies, subjects who received oxygen remembered shopping lists and faces better than subjects that didn’t receive oxygen (12-13, 18). 

Researchers have also found significant positive correlations between changes in oxygen saturation and memory performance (15). 

2. Normobaric Oxygen Therapy Improves Cognitive Performance

Research shows that concentrated oxygen significantly enhances cognitive performance (19-20, 29). 

And it doesn’t just improve cognitive function in the elderly; it also enhances cognitive processing in young adults (21-23). 

In one study, students that inhaled oxygen while playing a computer game performed much better compared to students who didn’t inhale any additional oxygen (26). 

In two other studies, researchers found that the inhalation of 30% oxygen improved cognitive functioning and performance by activating several brain areas (24-25). 

“Oxygen administration appears to facilitate cognition most effectively for tasks with a higher cognitive load.”

— Advances in Natural Medicines, Nutraceuticals, and Neurocognition

They concluded that breathing a higher concentration of oxygen increases blood oxygen levels in the brain, which then supports cognition (24-25). 

And other researchers have found significant correlations between blood oxygen levels and cognitive performance (27-28). 

3. Normobaric Oxygen Therapy Enhances Accuracy

Several studies have found that normobaric oxygen therapy can also increase your accuracy when doing tasks. 

Two studies found that 30% and 40% oxygen administration significantly enhanced accuracy rates compared to 21% oxygen (normal air). It did this by increasing oxygen levels in the blood, which then stimulated activity in the brain (31-32). 

As the difficulty of the task increased, the difference in the accuracy rate between 40% and 21% oxygen administration also increased (33-34). 

And researchers found a positive correlation between task performance and oxygen levels in the brain (33-34). 

Other research has found that 30% oxygen administration enhances accuracy rates during verbal tasks by activating specific areas of the brain (35-36). 

4. Normobaric Oxygen Therapy Reduces Reaction Time

People who receive normobaric oxygen therapy also have faster reaction times (37-38). 

In one study, participants performed visual matching tasks under 43% oxygen or 21% oxygen (normal air).

Researchers reported a significant decrease in reaction time in the presence of 43% oxygen (39).

The researchers hypothesized that normobaric oxygen therapy increases oxygen levels in the blood, which then leads to more available oxygen in the brain (39). 

Another follow-up study confirmed that response time decreases during normobaric oxygen therapy due to the increase in blood oxygen levels (40). 

Normobaric oxygen therapy has even been shown to reduce reaction time in children with attention deficit hyperactivity disorder (ADHD) (41). 

5. Normobaric Oxygen Therapy Increases Energy

“Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake.”

All cells within your body need oxygen, particularly your brain cells.

They require a lot of oxygen to produce energy. 

In fact, your energy levels depend on how much oxygen you have and how well your mitochondria utilize it.

If your brain doesn’t get enough oxygen, it simply won’t function properly, and you’ll end up feeling tired. 

But normobaric oxygen therapy can increase energy.

Research shows that it "decreases fatigue and reduces feelings of sleepiness" (51). 

6. Normobaric Oxygen Therapy Improves Neurological Function After Stroke

Researchers say that normobaric oxygen therapy is a promising therapy for stroke patients. 

It’s been shown to reduce brain swelling and blood-brain barrier permeability and increase brain blood flow after stroke (42-43). 

One study found that normobaric oxygen therapy significantly improved neurological functions in patients with acute ischemic stroke (44). 

Other researchers have found that normobaric oxygen therapy increases oxygen supply to damaged tissues and improves outcomes after stroke, in both animals and humans (45-46). 

As a non-pharmaceutical and non-invasive treatment, normobaric oxygen therapy is “worthy of notice” (47). 

7. Oxygen Therapy May Help Reverse Brain Damage After Traumatic Brain Injury

Researchers found that a combination of normobaric and hyperbaric oxygen therapy reversed brain damage in 2-year-old girl who nearly drowned in a swimming pool.

She received normobaric oxygen treatment (twice daily for 45 minutes by nasal cannula), and doctors witnessed significant improvements in her neurological function (48-49). 

Normobaric oxygen therapy alone improved the girl’s neurological function before she started hyperbaric oxygen therapy (48-49). 

She eventually made a full recovery with both types of oxygen therapy. 

Researchers have also said that the “neuroprotective role of normobaric oxygen therapy is extremely promising” for traumatic brain injury (50). 

I’ve also seen multiple studies with rats and mice showing that normobaric oxygen therapy reduces brain swelling and brain damage.

8. Other Possible Benefits (with Less Research Behind Them)

• Increases attention and vigilance – Oxygen administration significantly improved performance on several measures of attention and vigilance (52).

• Reduces inflammation – Oxygen levels play a critical role in determining the severity of the inflammatory response and ultimately the effectiveness of anti-inflammatory drugs (53-54).

• Improves hand-eye coordination (55).

• Increases positive sense of wellbeing (56).

My Experience with Normobaric Oxygen Therapy

“If you use oxygen for 20 minutes, muscles become loosened, headaches and stress seem to disappear, there is a renewed energy and a feeling of relaxation.”

— Dr. Richard de Andrea

 

I was first introduced to oxygen therapy through an integrative doctor I know.

At the end of each appointment with him, I would use his oxygen concentrator for about 15-20 minutes. He used this oxygen concentrator. 

I eventually decided to buy my own oxygen concentrator and now regularly use it at home. 

There is a dial for adjusting the flow of oxygen and the port is located on the upper right of the machine.

I bought this oxygen concentrator. I'll discuss how it has helped me below.

The oxygen from the concentrator is supplied through an nasal canula. It’s completely non-invasive and painless, and it’s become one of my favourite tools for supporting my brain.

I use it for about 20 to 30 minutes, a few times each week. I often do this while exercising on this indoor stationary bike. Sometimes I use it without exercising on the bike. 

I also use it for about 3 to 5 minutes as needed, usually when doing work. 

During a session, I use this oxygen saturation monitor to measure my blood oxygenation levels. 

Your blood oxygen saturation levels (SpO2) should measure 99-100%. I see mine increase and max out while using the concentrator. 

My oxygen concentrator delivers up to 5 litres of oxygen per minute. I usually set mine somewhere between 3 and 5 litres per minute. 

But I would recommend starting lower and working your way up. 

Similar to low-level laser/light therapy, oxygen therapy is somewhat experimental. You need to find the right “dosage” for yourself.

Benefits and What I’ve Noticed

I've had good results with concentrated oxygen therapy and it has surprisingly increased the quality of my life. 

One of the main things I notice is that it feels like it puts energy back into my body every time I use it.

One of my clients uses it whenever she gets brain fog, and it clears it up. Another client uses it when she gets a headache and the headache disappears within 10 minutes.

It also does an incredible job of getting rid of hangovers. They essentially go away if you use the concentrator the morning after drinking. You just immediately feel like a completely new person.

Here are some other benefits I’ve experienced:

• Increased energy and alertness

• Improved mood

• Increased cognitive function

• Improved memory and enhanced ability to work through difficult tasks

• More mental motivation, endurance and productivity if used during tasks

Keep in mind that this is my personal experience (and the experiences of a couple of clients). There really is no guarantee that you’ll experience the same results, but it’s worth a try if you’re sick and other therapies aren’t improving your brain function. 

Combining Oxygen Therapy with Other Therapies

I also combine oxygen therapy with other therapies and supplements for their synergistic effects. 

Researchers have found that combining normobaric oxygen therapy with the following therapies leads to better results (57-59):

• Exercise – Exercise with oxygen therapy (EWOT) is typically done with a full mask. But I simply use a nasal canula. My integrative doctor recommended AGAINST wearing a full mask when doing EWOT. I use this indoor stationary bike.

• Low-level laser/light therapy (LLLT)– I find I get even more positive effects if I combine oxygen therapy with low-level laser/light therapy (LLLT). My doctor combines the two as well. You can read more about LLLT here.

• Methylene blue – Normobaric oxygen therapy and methylene blue work better together at improving outcomes after stroke than either alone. I sometimes take methylene blue, particularly if I'm sleep deprived or within a high-EMF area.

• N-Acetyl-Cysteine (NAC) – Normobaric oxygen therapy has been shown to extend the neuroprotective effects of n-acetyl-cysteine (NAC). I take 250 mg of NAC daily.

• Melatonin – Melatonin and oxygen therapy work better together at supporting brain health than either alone. Sometimes I use my oxygen concentrator at night before bed, along with melatonin supplementation and/or blue blocking glasses that naturally increase my body’s production and release of melatonin.
