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 Proven Ways to Quickly Lower Your Cortisol Levels

Chronic stress is killer. 

It broke me down over the years and led me to deep depression.

Getting a handle on it has been critical to my recovery. 

But it took me a while to figure out what works.

And I’d rather not see other people struggle and frantically look for solutions.

So I’ve gathered some of my favourite ways to quickly lower levels of cortisol, your body’s main stress hormone.

But before we get to them, let’s quickly discuss cortisol and how chronically high levels of cortisol can negatively affect your brain and mental health. 

How Stress and Cortisol Affect Your Brain

Cortisol is known as the “stress hormone”.

It’s a naturally-occurring steroid hormone that’s produced by your adrenal glands and released when you’re under physical or mental stress. Essentially, it triggers our fight-or-flight response in stressful situations.

But it’s also absolutely necessary for our health, as it plays a key role in many different bodily processes. 

Cortisol levels are generally highest in the morning and lowest at night. But problems can arise when they are elevated for prolonged periods of time (134). 

Chronically high cortisol levels can:

• Change the size, structure and functioning of your brain;

• Shrink and kill brain cells;

• Cause premature aging in the brain;

• Contribute to memory loss and lack of concentration;

• Slow down our ability to grow new brain cells; and

• Increase inflammation in the brain (135-140).

Watch this TED-Ed video, “How Stress and Cortisol Affect Your Brain,” to learn more: 

Chronic stress and high levels of cortisol also increase activity in the amygdala, the fear centre of the brain. This can create a vicious cycle in which the brain is more likely be get stuck in a constant state of fight-or-flight.

When I did neurofeedback, my practitioner discovered my amygdala was overactive. She trained it back down to normal levels, and my chronic anxiety dissipated.

Anxiety isn’t the only mental condition linked to an abnormal stress response. Here are some others:

• Major depressive disorder;

• Bipolar disorder;

• Borderline personality disorder;

• Insomnia;

• ADHD;

• Anorexia;

• Bulimia;

• Alcoholism; and

• Dementia and cognitive impairment (135-150).

Luckily, there are a number of ways to manage and overcome chronic stress, lower cortisol levels, reverse damage done to the brain, and improve your sense of wellbeing. 

This article includes the best foods, nutrients, herbs and supplements that reduce cortisol; as well as the best lifestyle habits, therapies and practices that reduce cortisol.

Let’s go through them.  

The Best Foods, Nutrients, Herbs and Supplements To Naturally Lower Cortisol Levels

1. Eat Dark Chocolate

Most people know that dark chocolate is rich in multiple antioxidants, such as flavonols and polyphenols, which reduce oxidative stress.

But it also reduces cortisol. 

This may explain why people love to eat chocolate and experience relaxation when they do. 

Dark chocolate can protect your brain by boosting BDNF, your brain’s growth hormone. 

You should always try to get raw dark chocolate with the least amount of sugar.

2. Drink Tea

Several different types of tea have beneficial effects on cortisol levels. 

Green tea has been shown to inhibit the synthesis of cortisol (18). 

And a study found that individuals who drank 4 cups of black tea daily for six weeks had lower cortisol levels in comparison to others who didn’t drink black tea (2). 

Researchers couldn’t confirm what caused this reduction in cortisol, but they suspected it had something to do with the high content of theanine, an amino acid found in both black and green tea.

A follow-up study published this year confirmed that theanine can reduce cortisol (13).

Theanine produces a calming effect on the brain by crossing the blood-brain barrier and increasing the production of both GABA and dopamine in the brain (12). 

I personally can’t drink most teas because they tend to contain mycotoxins (mold toxins) and I’m very sensitive to them after living in a moldy home.

If you’ve lived in a moldy home or have found out that you’re genetically susceptible to mycotoxins, you can supplement with straight theanine like I do. 

This supplement includes theanine. 

And if you do decide to drink black tea, you can lower cortisol even more by getting decaffeinated black tea.

Lastly, chamomile tea is another type of tea that can decrease cortisol. It’s been used for centuries as a sleep aid. It contains flavonoids, essential oils, coumarin and other compounds that can help you relax.

Several studies show it can block the precursor hormone of cortisol and improve sleep quality (14, 15). 

This anti-anxiety supplement includes theanine, along with a number of other natural compounds that have helped me manage my stress and anxiety over the years.

3. Eat Extra Virgin Olive Oil

Olive oil has numerous health benefits, particularly because of its strong anti-inflammatory effects.

It also contains a compound called oleuropein, which can reduce cortisol levels (37). 

I add it to my salads and sometimes even take a tablespoon of it straight.

Be careful though. A lot of cheap extra virgin olive oil in grocery stores are not actually “extra virgin.”

Investigations have found that there is a lot of fraud within the olive oil industry and many so-called extra virgin olive oils contains other cheaper, refined vegetable oils, such as soybean, corn and canola. 

This is discussed more in the book Extra Virginity: The Sublime and Scandalous World of Olive Oil. 

4. Take Cortisol-Reducing Nutrients and Herbs

There are a number of nutrients, vitamins, minerals and adaptogenic herbs that have been shown to reduce stress and cortisol levels. 

I’ll go over some of my favourites here.

Phosphatidylserine is probably the best option for reducing stress hormone levels. 

Phosphatidylserine is a fat-soluble amino acid compound that plays a key role in optimal cognitive function. High amounts of phosphatidylserine can be found within the brain, and supplementation has been shown to improve attention and memory, especially in the elderly (114-116). 

“…consumption of phosphatidylserine may reduce the risk of dementia and cognitive dysfunction in the elderly.”

— Food and Drug Administration

On top of all this, phosphatidylserine powerfully lowers cortisol (117-119). 

People who supplement with phosphatidylserine have been shown to have lower average levels of cortisol (120).

I take phosphatidylserine every day. It's part of the Optimal Calm supplement. 

Ashwagandha is another great cortisol-reducing supplement. It’s a popular Indian herb commonly used to prevent anxiety. Its anti-anxiety effect is synergistic with alcohol.

Its stress-reducing effects are likely because it lowers cortisol levels. 

Multiple studies have concluded that it is a potent stress reliever that can reduce cortisol by anywhere from 14 to 32% (121-123). 

Ashwagandha is included in this supplement.

Another adaptogenic herb that can lower cortisol is rhodiola. 

I’ve discussed rhodiola before. It can really help with symptoms of depression. 

Research has found that it may be doing this by significantly reducing stress hormone levels in the body (124-126). 

Lastly, a number of minerals have been shown to reduce cortisol, including zinc, magnesium and selenium (96, 97, 127-133).

That’s why I take and recommend a multi-mineral supplement every day. 

Overall, ashwagandha, rhodiola, phosphatidylserine and minerals are my favourite ways to keep stress levels low, but there are plenty of other supplements that have been shown to positively affect cortisol levels, including:

• Omega-3 Fatty Acids (93, 94)

• N-Acetyl-Cysteine (95)

• Ginseng (98, 99)

• Tribulus (100)

• Bacopa (101)

• Schisandra (102, 103)

• Ginkgo Biloba (104)

• St. John’s Wort (105)

• Lemon Balm (106)

• Holy Basil (107)

5. Consume Enough Food, Protein and Water

Eating enough protein and calories, and drinking enough clean, filtered water is also critical to keeping stress hormone levels low.  

Studies show that severely restricting calories elevates cortisol levels (108, 109). 

Restricting protein and depriving yourself of the amino acid leucine can also stimulate the stress response and increase stress hormones (110). 

That’s why I eat plenty of food each day and supplement with creatine and BCAA protein powder throughout the day when I don’t have access to a source of high-quality protein. 

Lastly, make sure you stay hydrated and drink plenty of water.

Properly-hydrated runners have noticeably lower cortisol levels than dehydrated runners (81).

I use a high-quality filtration system to filter my water so that it’s as pure as possible.

6. Consume More Omega-3s and Less Omega-6s

As I’ve discussed before, omega-3s are dietary fats that are needed for the proper functioning of your brain and nervous system. They improve learning and memory, and protect against psychiatric disorders including depression, mild cognitive impairment, dementia and Alzheimer's disease (4-7). 

Researchers have also found that when individuals supplement with omega-3 fatty acids, there is a significant reduction in the release of cortisol (1, 10).

Omega-3 fatty acids also significantly reduce stress hormones in animals (3). 

Krill oil is my favourite source of omega-3 fatty acids.

I also eat wild salmon and grass-fed beef on a regular basis. 

On the other hand, consuming too many omega-6 fatty acids have been linked to increased inflammation and cortisol levels (8, 9, 11).

So make sure to avoid refined vegetable oils such as soybean, corn, safflower, sunflower, and canola oil.

7. Get Enough Antioxidants

Not only do antioxidants counteract oxidative stress within the body; they can also help reduce cortisol (19, 25). 

Most of the research has been done in athletes, but supplementation with antioxidants – such as berry powders, greens powders, vitamin C, glutathione and CoQ10 – leads to fairly significant reductions in cortisol and other measures of stress (20-23). 

Dark berries in particular contain antochyanins, which have been shown to lower cortisol (24). 

Acai berries are my favourite, as they are loaded with antochyanins and vitamin C.

Regarding vitamin C, the research is mixed on whether it can consistently lower cortisol levels.

However, in my experience, high doses of vitamin C definitely reduce stress.

One study found that a high dose of vitamin C decreases anxiety and improves mood (29). 

After exercise, it’s also been shown to rapidly reduce cortisol (26, 27). 

And multiple other studies have found that both vitamin C and vitamin E reduce cortisol and anxiety (30-32). 

It’s also well known that chronic stress and high cortisol can deplete vitamin C and other antioxidant enzymes (28). 

In addition to getting vitamin C from fruits and vegetables, I take at least 500 mg of supplemental Vitamin C every day. I’ve experimented with taking up to 10 grams daily (2 gram doses throughout the day) and it helped me manage stress, but it’s not necessary unless you find it really helps you. 

Vitamin C and Vitamin E are both included in this supplement, along with several other antioxidant nutrients.

8. Take Curcumin

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

Curcumin is one of my favourite compounds for the brain and mental health.

Thousands of high-quality scientific studies have been published, showing that curcumin has anti-inflammatory and antioxidant effects and can increase BDNF, your brain’s growth hormone. 

Research shows that curcumin inhibits the increase in cortisol caused by stress (33, 34). 

And animal studies have found that curcumin may reverse elevated cortisol levels after chronic stress (35, 36). 

Unfortunately, curcumin is very inefficient at absorbing into the bloodstream and reaching the brain (54, 55).

Luckily, science and technology has been able to concentrate significant amounts of curcumin into supplement form and increase its bioavailability. 

I get my curcumin from the Optimal Energy supplement.

Since curcumin is a fat soluble, I take it every day with a fatty meal.

9. Eat Prebiotic Foods

Prebiotics are substances in food that humans can't digest, so they pass through our gastrointestinal tract and promote the growth of many different strains of good bacteria in our lower bowel.

They are essentially food for the probiotics in our intestines.

Dr. Phil Burnet, a neurobiologist at Oxford University, published a paper in 2015 showing that people who ingested prebiotics have lower levels of cortisol.

The people who ingested prebiotics also focused more on positive feedback and less on negative stimuli.

Dr. Burnet said the results were very similar to when people take anti-depressants and anti-anxiety medication, but without the side effects (87).

That’s why I eat prebiotic-rich foods regularly, including sweet potatoes, carrots, onions, asparagus and squash. These foods are included in my free grocery shopping guide for optimal brain health. 

Resistant starch is one of the most potent ways to boost your prebiotic intake. A convenient way to incorporate more of it into your diet is by using and eating potato starch. Other high-quality resistant starches include banana flour, plantain flour and waxy maize. Cooked and cooled white rice and potatoes also contain some resistant starch. 

I previously discussed prebiotics and resistant starch here.

I also created and take Optimal Biotics, which is a premium probiotic supplement that reduces stress and support my mental health. 

10. Limit Alcohol and Caffeine

Excess consumption of alcohol and caffeine have been shown to increase stress hormones, so their consumption should be limited. 

Coffee is definitely good for brain health. There is a lot of research showing it is very healthy and can be protective against dementia. 

However, it can also disrupt sleep and make people anxious. I used to not be able to handle any coffee at all. But now that I'm healthy, I can handle it just fine. I drink one cup of high-quality coffee most mornings.

But if you’re struggling with high cortisol and chronic stress, I wouldn’t recommend high doses of caffeine.

It’s been shown to directly stimulate the adrenal cortex, release cortisol into the bloodstream and increase stress hormone levels (74-76).

One study found that caffeine increased cortisol by 30% in just one hour, and regular consumption can double your cortisol levels (88, 89). 

So limit it as much as possible.

An alternative solution is to consume the whole coffee fruit, instead of drinking coffee.

The coffee fruit doesn’t contain caffeine, but it does contains several healthy compounds not found in coffee beans themselves.

Scientists have discovered that ingesting whole coffee fruit concentrate significantly increases brain function. Coffee fruit concentrate can be found in the Optimal Brain supplement. 

Lastly, excess alcohol consumption over an extended period of time has also been shown to raise cortisol levels. Having a couple drinks here and there likely isn’t a problem though, and you can protect yourself from it by following these steps (90, 91). 

Certain types of alcohol are better to drink than others.

The Best Lifestyle Habits and Practices to Naturally Lower Cortisol Levels

11. Laugh

In the book The Anatomy of an Illness as Perceived by the Patient, Norman Cousins explains how he cured himself of ankylosing spondylitis by laughing along with Marx Brothers movies.

“I made the joyous discovery that ten minutes of genuine belly laughter had an anesthetic effect and would give me at least two hours of pain-free sleep. When the pain-killing effect of the laughter wore off, we would switch on the motion picture projector again and not infrequently, it would lead to another pain-free interval.”

— Norman Cousins

It sounds farfetched, but more and more research is showing that laughter has a powerful effect on our health. 

Researchers have found that laughing and having fun significantly reduces stress hormone levels (65, 66). 

In one study, laughter improved the short-term memory of older adults, and simply anticipating humour decreased their cortisol levels by nearly 50% (64). 

So, next time you’re stressed, try watching a funny TV show or YouTube video. 

12. Play with Animals

This is my cat named Puddy. He's annoying but he does reduce my cortisol levels.

Petting your own dog or another person’s dog has been shown to significantly decrease stress hormone levels and increase oxytocin, endorphins, and other healing hormones (71, 73). 

Researchers have also compared 20 minutes of quiet rest to 20 minutes of interaction with a dog, and they found that hanging out with dog contributed to a much more significant decrease in cortisol. This is often why therapy dogs show up on college campuses during exams (71). 

So you should try to hang out with animals as much as possible, and consider getting a house pet if you don’t have one. I have a cat named Puddy. 

Spending time in nature has also been shown to reduce cortisol levels. So you can kill two birds with one stone by taking your pet for a walk in the park (77). 

Hmm perhaps “kill two birds with one stone” wasn’t the best idiom to use in this section, but you get my point. 

13. Listen to Music and Dance

Music is actually healing and can have a calming effect on the brain. 

Numerous studies show that music can relax you, especially before a stressful event, by significantly lowering stress hormones. It can also reduce the spike in cortisol during the stressful situation (50-54). 

Music can be even more relaxing when combined with non-strenuous dancing.

Regular dancing has also been shown to greatly decrease cortisol levels (55). 

14. Practice Relaxation Techniques and Therapies

Not too surprisingly, simply taking time each day to relax can lower cortisol.  

My favourite relaxation technique is meditation. 

Countless studies show that meditating daily for just 15 minutes can significantly lower stress hormone levels and blunt cortisol spikes (38-43). 

I use the Muse headband to meditate. Similar to neurofeedback, it gives you real-time feedback on your brainwaves. I previously wrote about it here, and you can get it through the Muse website. 

Yoga has also been shown to lower cortisol. 

In one study, people with depression practiced yoga regularly for 3 months. By the end of the study, their cortisol levels dropped significantly and they experienced relief from their depression (44). 

Massage is another excellent option, as it’s been shown in many studies to significant decrease in cortisol and anxiety (45, 46). 

I get a massage every couple of months. 

Emotional Freedom Technique, or “tapping”, is another tool I use to manage stress. 

Tapping is based on ancient Chinese acupressure and modern psychology. You can learn how to practice it here. 

I know it seems hokey, but it works. 

It’s been shown to significantly decrease cortisol levels (47). 

The book The Tapping Solution: A Revolutionary System for Stress-Free Living goes in more depth about the practice. 

Lastly, deep breathing exercises can help you manage your stress hormone levels. 

Diaphragmatic breathing – consciously breathing from your diaphragm – has been shown to encourage the body’s natural relaxation response and reduce cortisol (48, 49). 

I use the EmWave2 device every day to reduce stress and make sure I’m breathing optimally. I wrote about it before here.

15. Exercise (But Not Too Much)

Exercise is definitely good for you. It can balance hormones and reduce stress by releasing endorphins. However, overtraining can actually backfire and increase stress hormone levels (112). 

That’s why I don’t really recommend chronic endurance exercise and prefer weightlifting and high-intensity sprinting over cardio. 

Research shows that prolonged aerobic exercise can increase cortisol levels, and marathon runners have higher levels of cortisol (111, 113). 

16. Get More Deep Sleep

This might be the most important step. 

Getting enough high-quality sleep is critical for your brain and mental health. 

My sleep used to be terrible and it was one of main factors that contributed to my poor mental health. And then my poor mental health would make my sleep worse. So it was a vicious cycle. 

Let me explain.

Normally, cortisol increases in the morning and then drops very low at night prior to bed. But if you have chronic stress and high cortisol, you can end up feeling wired and anxious at night, making it more difficult to sleep. 

Unfortunately, staying up late when your body expects to be asleep further increases your stress hormone levels even more. And lack of sleep and interrupted sleep have been shown to significantly increase cortisol throughout the next day and contribute to cognitive problems down the road (56-61, 63). 

So it’s clearly a vicious cycle where high cortisol causes sleep problems, and poor sleep increases stress.  

That’s why it’s so important go to bed at the same time every night and aim for at least 7 hours of sleep every night. Without doing that, you can end up with dysregulated daytime cortisol production.

And it’s not just the amount of sleep you get that’s important. It’s also the quality of sleep. In fact, the quality of your sleep is more important than the length of your sleep.

So I would try doing everything you can to maximize the quality of your sleep. 

I share my very best sleep tips with my clients through our Brain Recovery Accelerator Program. We have a free online workshop that talks about the program. You can register for the workshop here.

You could also take this sleep supplement, which contains magnesium and a number of other natural compounds that I’ve used over the years to improve sleep.

And if you don’t get enough sleep one night, try to take a nap sometime the next day. Daytime napping after a night of sleep loss has been shown to cause beneficial changes in cortisol levels (62).

17. Chew Aspartame-Free Gum

Next time you’re stressed, try chewing a piece of gum. 

It’s an easy way to lower your stress hormone levels. 

According to one study, chewing gum while under moderate stress reduces mental stress and decreases cortisol by 12 per cent. Previous studies have also shown that chewing can increase alertness, neural activity and blood flow to the brain (82). 

I prefer if the gum is aspartame-free.

18. Stand Tall

Changing your body language can have a powerful effect on your biology. 

Standing tall for just two minutes can lower your cortisol by 25 per cent, according to a famous study led by Harvard social psychologist Amy Cuddy (83). 

Cuddy’s research found that if you switch from low-power body language (arms crossed, hunched over, closed up, slumped shoulders, nervous) to high-power body language (opened up, tall, relaxed, confident), your hormones will change to match your new posture (84). 

So try your best to maintain high-power body language as much as possible as it can reduce stress hormones and increase confidence. You could even try holding a dominant pose for 2 minutes every day. You’ll likely find yourself feeling calmer and more mentally powerful.

And if you haven’t already, check out Amy Cuddy’s TED talk “Your Body Language Shapes Who You Are”.

I also recommend her book Presence: Bringing Your Boldest Self to Your Biggest Challenges.

19. Socialize

Social connectivity and positive social interactions also significantly reduce stress hormone levels.

Research shows that the more social support a person has, the lower their cortisol levels will be (67). 

This is likely because you release the hormone oxytocin during social contact and social bonding, and oxytocin has been proven to decrease anxiety and block increases in cortisol (68). 

One study states that “the combination of oxytocin and social support exhibited the lowest cortisol concentrations as well as increased calmness during stress” (69). 

Animal studies have also discovered that social isolation leads to higher cortisol and mental health problems (70). 

Make sure to check out my full article about oxytocin to learn more about this powerful neurotransmitter.

20. Other Cutting-Edge Therapies

Here are some other therapies that have been shown to reduce stress and cortisol:

• Bright Light Therapy (85, 86).

• Transcranial direct current stimulation (78)

• Transcranial magnetic stimulation (79, 80)

• Acupuncture (92)

Conclusion

It’s important to take control of your stress before it takes control over you.

Thankfully, there are so many ways to manage your stress and lower cortisol levels without having to resort to a prescription. 

Here’s a summary of everything we’ve gone over to reduce stress hormone levels:

• Eat wild salmon, grass-fed beef and krill oil, and avoid refined vegetable oils

• Drink black, green and chamomile tea, or supplement with theanine

• Eat dark chocolate :-)

• Get enough antioxidants, including vitamin C, vitamin E, glutathione and CoQ10

• Eat turmeric and/or supplement with curcumin

• Add extra virgin olive oil to meals

• Relax with meditation, the Muse headband, yoga, massage, tapping, deep breathing, and the EmWave2

• Listen to music and dance

• Sleep deeper

• Watch comedy and laugh

• Socialize

• Play with animals

• Chew aspartame-free gum

• Stand tall with powerful body language

• Limit alcohol and caffeine

• Eat prebiotic foods, including resistant starch

• Eat enough food and protein

• Drink enough filtered-water

• Exercise, but not too much

• Supplement with phosphatidylserine, ashwagandha, rhodiola and/or minerals

I remember when I first discovered all of these tools and strategies, it gave me so much hope that I could get better and overcome my depression and anxiety.

And I thankfully I did.

And you can too.
