Now for a more detailed look at these supplements:

Andrew Huberman Sleep Cocktail

Andrew hopes that most people are able to fall asleep without assistance.

However, for those who can’t, he’s quick to point out there’s a middle ground between doing nothing, and taking sleeping medication. The latter of which can come with nasty side effects and sometimes addiction.

The sleep cocktail that Andrew says has been amazing for his sleep are:

  • Magnesium Threonate – 140mg
  • L-Theanine – 100-300mg
  • Apigenin – 50mg

All 3 taken ~60 minutes before bed.

Then, if he really needs sleep, 3-4 times per week he also uses:

  • 2g of Glycine
  • 100mg of GABA

It’s worth noting that for many people, even just the addition of magnesium and/or theanine may have a positive effect on their sleep.

After the audio clip we discuss all these sleep supplements in more detail.

^ A clip from Episode 28 of Andrew’s podcast

Magnesium L-Threonate

Magnesium is very important to the human body, and is involved in over 600 enzymatic reactions1Magnesium in man: implications for health and disease – Bindels et al. | 2015 | Physiological Reviews.

Specific to sleep, magnesium supplementation can activate the parasympathetic nervous system2Long-term HRV analysis shows stress reduction by magnesium intake – Nolden et al. | RCT, n=100 | 2016 | MMW – Fortschritte der Medizin, which is responsible for, among other things, slowing the heart and relaxing the muscles – producing a calming effect.

For those who aren’t getting adequate amounts of magnesium from their diets, which is approximately 48% of Americans3Perspective: The Case for an Evidence-Based Reference Interval for Serum Magnesium: The Time Has Come | Costello et al. | 2016 | Advances in Nutrition, supplementing it can have a noticeable affect on sleep.

Andrew personally preferences Threonate, but notes that Glycinate (also known as Bisglycinate) appears to work well too – as both can cross the blood-brain barrier.

In terms of suggested dosage for magnesium Andrew mentions:

  • 100-200mg in this YouTube video
  • 200-400 in this interview
  • Then in the tweet below he says 140mg

^ Image source

My interpretation is that the dose is dependent upon the form of Magnesium. If it’s Magnesium Threonate, then less is suggested (~140 mg), whereas with bisglycinate, the standard dose is slightly higher (200 mg or more).

For context, the Recommended Dietary Allowance (RDA) of Magnesium is around 420 mg per day for men and 320 mg for women, according to the NIH.

Examples of reputable brands of L-Threonate include:

ProductServingsPriceCost per 144mg
DoubleWood – L-Threonate25x 144mg$25 with coupon$1.01
Momentous – L-Threonate30x 144mg$42 with coupon$1.41

Magnesium Threonate is typically more expensive than other magnesium sources due to it being patented and sold as “Magtein” – more info.

Andrew’s Dose: ~140mg of Threonate

Magnesium glycinate is a good alternative that is noticeably more affordable. Reputable brands include:

ProductCapsulesPriceCost per 100mg
Pure Encapsulations – Magnesium Glycinate90x 120mg$23$0.21
Double Wood – Magnesium Glycinate180x 60mg$17 with coupon$0.16


Theanine (or L-Theanine) is an amino acid. For example, it is found in tea and can have calming effects when supplemented4Theanine consumption, stress and anxiety in human clinical trials: A systematic review – Naumovski | Meta-review | 2016 | Journal of Nutrition & Intermediary Metabolism..

One of the ways it does this is to increase “alpha brain waves” – a type of brain wave that is associated with calm and relaxation5L-theanine, a natural constituent in tea, and its effect on mental state – Owen et al. | 2008 |Asia Pacific Journal of Clinical Nutrition.

As opposed to Beta and Gamma brain waves – which are associated with alertness and problem solving.

Andrew notes that theanine can increase the intensity of dreams, and thus may not be suitable for those with night terrors or who sleepwalk.

Again, as with threonate above, Andrew has mentioned different doses at different times. For example, 100-300mg and 200-400mg. Granted it’s all in the same ball park. If you’re new to theanine, it’s probably best to start at the bottom end of the dosing scale (~100mg) and gradually increase as you see fit.

Andrew notes that for a small percentage of people, Theanine can be too stimulating:

Examples of reputable brands include:

ProductCapsulesPriceCost per 100mg
DoubleWood – Theanine120 x 200mg$16 with coupon$0.07
Momentous – Theanine60 x 200mg$34 with coupon$0.28

Andrew’s Dose: 100-300mg


Apigenin is one of the active ingredients in chamomile tea, and according to Andrew can help promote sleep and sleep onset.

Andrew notes that apigenin is a mild estrogen suppressor, and he doesn’t think women should take it.

He also notes that for men, taking estrogen levels too low can affect brain health and libido.

^ Clip from Andrew’s appearance on Kevin Rose’s podcast (link)

Authors note: Based on apigenin suppressing estrogen, it appears to be a supplement you’d want to be cautious of taking regularly. At least until there’s more research.

Examples of brands include:

Andrew’s Dose: 50mg

GABA & Glycine

^ Clip from Tim Ferriss interview (link)

Andrew says that if you ever really need to sleep, taking GABA and Glycine can help.

He describes it more as a “hard hit over the head”, and doesn’t recommend people take it regularly.

His reasoning being that he doesn’t like to take things that are too close to the neurotransmitter you’re trying to manipulate. In this case, taking GABA to manipulate the GABAergic system.

GABA (Gamma-aminobutyric acid) is the main inhibitory neurotransmittor in the brain. When supplemented it’s often with the intention that it will have a calming effect on the nervous system. There is some debate as to whether GABA crosses the blood-brain barrier6Effects of Oral Gamma-Aminobutyric Acid (GABA) Administration on Stress and Sleep in Humans: A Systematic Review – Hepsomali et al. (2020) | Frontiers in Science. Whether it does or does not, it may also act on the peripheral nervous system through the gut-brain axis7Gamma-aminobutyric acid as a bioactive compound in foods: a review – Diana et al. (2014) | Journal of Functional Foods.

Glycine is a non-essential amino acid, abundant in animal products. It’s thought to improve sleep by helping to reduce the core body temperature8New Therapeutic Strategy for Amino Acid Medicine: Glycine Improves the Quality of Sleep – Bannai et al. (2012) | Journal of Pharmacological Sciences.

Dosage: In the audio clip above Andrew mentions 1g of GABA and 1g of Glycine. However, in Andrew’s toolkit for sleep and on Twitter he mentions 2g of Glycine and 100mg of GABA taken 3-4 times per week.

In his tweet he describes the Magnesium, Theanine & Apigenin combo, and then goes on to say he *also* takes GABA & Glycine 3-4 times per week. Which I take to mean, in addition, rather than in place of.

Side Effects: GABA can have sedative like effects at higher doses, therefore it’s important to treat it with caution. Do not combine it with driving a vehicle or operating machinery.

For those already taking drugs that interact with the GABAergic system, such as barbiturates and benzodiazepines, it would be especially important to consult with your doctor before taking GABA.

Examples of GABA brands include:

Examples of Glycine brands include:


In Andrew’s recent video on OCD, he mentions experimenting with taking 900 mg of myo-inositol alongside his sleep cocktail of magnesium threonate, theanine and apigenin.

Saying that he has noticed an improvement in his sleep since taking it.

^ Audio clip from Andrew’s podcast #78 on OCD from 2:04:51

Inositol is a type of sugar, found in the brain and other tissues, which mediates cell signal conversion in response to hormones, neurotransmitters and growth factors. When these external signals reach the cell they are converted into internal messengers, for which myo-inositol is involved9The cellular language of myo- inositol signaling | 2011 | Glenda E. Gillaspy.

To clear up some potential confusion on inositol naming, there are at least 3 different inositol supplements:

  • Myo-inositol
  • D-chiro-inositol
  • Inositol hexaphosphate (IP6)

If a supplement is simply named “inositol”, it’s usually myo-inositol – but it’s worth checking to be sure.

Examples of brands include:

Increasing Testosterone

Andrew appreciates the importance of healthy levels of testosterone, and suggests before adding any supplements “the basics” need to be in check, which are:

  • Good quality sleep
  • Healthy diet
  • Regular exercise (but not over trained)
  • Avoiding chronic stress

However, once those boxes are ticked, he mentions 2 supplements that have been useful for him; Tongkat Ali and Fadogia Agrestis.

He says that 6 years ago, his total testosterone was at around 600. After he started taking Tongkat Ali and Fadogia Agrestis, it went up  approximately 200 points to the high 700s / low 800s (ng/dL).

He continued taking these supplements consistently for several years.

Tongkat Ali

Tongkat Ali comes from a plant that’s native to Southeast Asia. There it’s treated as a medicinal plant and has many different uses10Tongkat Ali (Eurycoma longifolia Jack): A review on its ethnobotany and pharmacological importance – Karim et al. | Fitoterapia | 2010.

Andrew explains that Tongkat Ali will increase testosterone when taken at 400mg daily. He suggests:

  • Taking it early in the day as it can have a mild stimulant effect.
  • Taking it every day, rather than intermittently, as the effect appears to improve as you get into the second and third month of use.
  • No need to cycle it, unless something has spiked on your blood tests – such as liver enzymes – suggesting the need to stop.

Examples of brands include:

Andrew’s Dosage: 400mg per day (regular Tongkat, rather than LJ100)

Fadogia Agrestis

Fadogia Agrestis is a plant found natively in Nigeria, for which the stem is used as a herbal medicine to treat a range of issues.

For the purposes of testosterone increase, Andrew describes Fadogia as increasing Luteinizing Hormone (LH), which then stimulates the testes to produce more testosterone.

In Andrew’s second interview with Dr Kyle Gillett (link), Andrew says he’s been taking 600 mg per day – for 8-12 weeks at a time, then taking a few weeks off.

Andrew notes that he monitors his blood regularly, and hasn’t seen any negative impact on his blood markers.

In the interview Kyle notes a couple of approaches he takes when using it with patients to increase their testosterone. For those who are not getting blood work done regularly, he suggests either:

  • Taking 600 mg every other day


  • Taking 600 mg 3 times per week, such as Monday, Wednesday, Friday

Then for those who are measuring their bloods regularly, a more aggressive regimen can be:

  • 600 mg daily for a month, and then take 1 – 2 weeks off

Kyle says that the caution in taking it daily, without any breaks, stems for a rat study that found on higher doses there was disruption to liver and kidney enzymes11Mode of cellular toxicity of aqueous extract of Fadogia agrestis (Schweinf. Ex Hiern) stem in male rat liver and kidney – Yakubu et al. | 2009 | Human & Experimental Toxicology. He notes that this hasn’t yet been replicated in humans, but still leans on the side of caution.

Examples of reputable brands include:

Andrew’s Dose: 600 mg per day


It’s worth briefly mentioning Turkesterone, after Andrew discussed it on a Joe Rogan podcast episode. It’s worth noting though, that he hasn’t taken it before himself.

^ Above audio clip from Joe Rogan podcast #1683, at 61m 26s – video clip here

Andrew talked up the properties of turkesterone quite highly, saying that it increases testosterone, performance and recovery comparatively to Deca – a well known anabolic steroid used by bodybuilders.

Looking at the literature, it doesn’t appear to be well studied in humans, and I can’t find research papers to back up his claim. The studies so far appear to be in-vitro and in animals. It’s possible it will be more formally studied in time.

It’s referred to as being part of the ecdysteroid family. Meaning that it’s a steroid hormone used by a specific group of insects (anthropods). In the same way that humans and other mammals manufacture hormones from cholesterol, so do anthropods. It also happens that the hormones they use are similar to ours.

That said, the supplement version of turkesterone isn’t extracted from insects, it’s extracted from plants. Specifically, Ajuga turkestanica, a flowering plant native to central Asia.

Examples of brands include:


Andrew points to a 2020 paper12The causes of adverse changes of testosterone levels in men – Wrzosek et al. | 2020 | Expert Review of Endocrinology & Metabolism Journal showing that testosterone levels are negatively impacted by deficiencies in zinc, magnesium and vitamin D.

We discuss magnesium for sleep (above), and vitamin D (below), so in this section we’ll focus on zinc.

Zinc is crucial to the creation of Luteinizing Hormone and Follicle Stimulating Hormone. Luteinizing Hormone in males stimulates the testes to produce testosterone. Meaning insufficient zinc can result in less testosterone.

Whilst the mechanism is slightly different in women, insufficient zinc will also negatively affect women’s testosterone levels13Effect of Zinc on Testosterone Levels and Sexual Function of Postmenopausal Women: A Randomized Controlled Trial – Nia et al. | 2021 | Journal of Sex & Marital Therapy.

Fun fact, whilst women have less testosterone than men, if you normalize their hormone values to the same units of measurement, they have more testosterone than all other hormones, including estrogen. Testosterone is the precursor to making estrogen (estradiol).

It’s worth noting that if you have adequate zinc levels, adding more zinc won’t boost your testosterone. Only that not getting enough is likely to decrease testosterone levels.

NIH guidelines suggest males need 11 mg per day and women need 8 mg. With an upper limit guideline of around 40 mg for both sexes.

Zinc picolinate has been shown to be one of the most bioavailable forms of zinc14Comparative absorption of zinc picolinate, zinc citrate and zinc gluconate in humans | Barrie et al. | 1987 | Bioinorganic Interaction.

Brands of zinc include:

For Boosting Cognitive Function


– For hard workouts or work sessions

One of Andrew’s preferred supplements for supporting cognitive function is Alpha-GPC (up to 3-5x per week). Mentioned as recently as Nov 8 2022 (link).

If he really wants to push a gym session, or work session, he’ll take 300mg of Alpha-GPC prior. Combining it with coffee or yerba mate, and sometimes adding phenylethylamine also.

^ Listen to the full podcast here – this section is around ~2hr 13m mark

Alpha GPC + Stroke Risk?

In podcast #80 Andrew mentions that a study found an association between long term use of AlphaGPC and increased risk of stroke15Association of L-α Glycerylphosphorylcholine With Subsequent Stroke Risk After 10 Years – Lee et al. (2021) JAMA Neurology.

One possible reason for this is that AlphaGPC increases blood levels of a chemical called TMAO, which itself is associated with atherosclerosis.

It’s worth noting that this study looked at a cohort in Korea taking AlphaGPC regularly for cognitive decline.

Whilst the paper doesn’t specify their daily dosage, I reached out to the lead author (Gyeongsil Lee) to learn more. He said that in Korea, the typical dosage prescribed by doctors there is 400mg 3x per day, so 1,200 mg per day, every day.

So what they’re taking in a single day is roughly comparable to what Andrew might take in a week.

Andrew’s approach to reduce his TMAO levels (a tip from Dr Kyle Gillett, former podcast guest), was to add 600 mg of garlic (which contains allicin) the same day as taking AlphaGPC.

Saying that his bloodwork showed a decrease in TMAO after he added the garlic. Solaray make a 600mg garlic supplement (link).

Examples sources of AlphaGPC include:

BrandCapsulesCost per bottleCost per 300mg
Double Wood – AlphaGPC60 * 300 mg$19.95$0.33
Momentous – AlphaGPC60 * 300 mg$38 with coupon$0.63
Jarrow – AlphaGPC60 * 300 mg$23.07$0.38

Andrew’s Dose: 300mg


– For improved focus and attention

Very occasionally (1x per week maximum) Andrew will use 500mg to 1,000mg of L-Tyrosine – which is a precursor to dopamine.

Pathway = L-Tyrosine -> L-Dopa -> Dopamine

He finds it enhances focus and attention, but it does come with a crash after. Noting that you don’t want to use it when you’re already sleep deprived.

He says that sensitivity to L-Tyrosine varies a lot. Some people can tolerate up to 2,000 mg, others find 100 mg is plenty, and for some the optimal dosage is zero.

He uses it occasionally, and has found it useful for working late to meet a deadline, but generally tries to avoid that.

^ Listen to the full podcast with Kevin Rose

Examples of L-Tyrosine supplements include:

Cost per 500mg
Momentous – L-Tyrosine60 * 500$24 with coupon$0.40
Thorne – L-Tyrosine90 * 500mg$23$0.25

Andrew’s Dose: 500mg

Related to dopamine precursors, Andrew mentions a supplement called Mercuna Pruriens which contains the direct precursor to dopamine; L-Dopa. However, he avoids Mercuna Pruriens because he finds it too intense with too much of a crash after.

Phenylethylamine (PEA)

Phenylethylamine, also known as beta-phenylethylamine, or PEA for short – is supplement, like L-Tyrosine, which increases dopamine.

Interestingly, chocolate is naturally rich in PEA.

Andrew says he takes it occasionally as a work aid to enhance focus, about once a week or once every 2 weeks.

He combines 500 mg of PEA with 300 mg of AlphaGPC, and says it leads to a sharp and transient increase in dopamine that lasts around 30 to 45 minutes. He finds the feeling from PEA more regulated and balanced than L-Tyrosine.

In terms of sourcing Phenylethylamine, there are a few options on Amazon. Although when I last checked none were from well known brands.

It’s worth being careful you don’t buy Phenylalanine by accident. The names look similar, but the effects are quite different.

If you’re thinking of trying PEA, it’s worth glancing over the potential side effects at this link prior.

For Maintaining Good Cognitive Function

Omega-3 Fatty Acids / EPA

Andrew explains that the most important food element for brain function is fat.

60% of the brain is made up of fat, and the remaining 40% is made up of water, protein, carbohydrates and salts16Essential fatty acids and human brain – Chen et al. | Acta Neurologica Taiwan | 2009.

Noting that while most of us get enough omega-6 fatty acids, it’s common to under consume omega-3s.

Andrew suggests that everyone should be striving to get at least:

  • 1 gram of EPA omega-3 oil per day

Potent sources include sardines, mackerel, salmon and caviar. Vegetarian sources include chia seeds, hemp seeds, flax seeds and walnuts.

Andrew aims to consume 2-3 grams of EPA per day, opting to take it as a fish oil supplement, on the basis that he rarely eats fish.

When it comes to omega-3 sources, it’s easy to just pick up any old option, and tick the box.

However, as with many things, the more you learn about them the more complexity there is.

For example, as with all oils, it’s possible for them to ‘oxidize’. This is a chemical reaction involving oxygen that degrades the quality of an oil. There are levels of oxidation from very little, all the way up to being noticeably rancid tasting.

Another aspect is the presence of heavy metals. As you’re probably aware, fish accumulate heavy metals, and the bigger the fish, typically the more heavy metals they contain. Therefore, ideally your fish oil is sourced from smaller fish such as sardines and anchovies, which typically contain less heavy metals.

Oil can then be purified to decrease contaminants.

So how does one choose fish oil that contains low levels of oxidation and heavy metals?

Ideally you want to choose products that have been tested and found to reliably contain low levels. We’ll go on to discuss how to do this.

Although it’s worth pausing for a moment to point out that omega-3s sourced from algae, rather than fish, generally have low levels of oxidation and heavy metals.

The downside? Per gram of EPA & DHA they’re a lot more expensive.

Algae based omega-3s, as you’d imagine, are particularly popular with vegans and vegetarians.

So, how does one check this in the fish oils that they’re interested in buying?

Probably the best source is one called IFOS (International Fish Oil Standards) who offer a certification to brands who opt in. They will then test batches and report on heavy metals and oxidation levels.

It’s their data that I’ve included in the table below.

A second source of third party testing is

Below are examples of reputable fish oil brands, along with the 3rd party testing data on total oxidation and heavy metals:

Name Price Flavored?
Quantity EPA/DHA

No data** N/A**

*Oxidation levels & heavy metal results come via IFOS batch tests
**Thorne and Momentous do not participate in IFOS testing, hence no data

Vegan / Vegetarian Fish Oil Alternatives?

Andrew personally opts to get his omega-3s from fish oil, due to its high levels of EPA & DHA per gram.

However, for those who don’t consume fish products, getting enough EPA and (particularly) DHA can be difficult.

Often vegetarians/vegans will rely upon consuming foods that contain alpha linolenic acid (ALA), but this has a few issues:

  1. ALA is weakly converted to EPA – Research estimates between 0.2% to 6% of ALA is converted to EPA17Metabolism of α-linolenic acid in humans – G.C. Burdge | (see section 7.2 of paper) | 2006 | Journal: PLEFA.
  2. ALA barely converts to DHA – The same research paper above estimates 0.05% or less of ALA is converted to DHA18Metabolism of α-linolenic acid in humans – G.C. Burdge | (see section 7.2 of paper) | 2006 | Journal: PLEFA.
  3. This aligns with research showing that vegetarians and vegans have lower levels of EPA & DHA compared to those who eat fish19Blood docosahexaenoic acid and eicosapentaenoic acid in vegans: Associations with age and gender and effects of an algal-derived omega-3 fatty acid supplement – Sarter et al. | 2014 | Clinical Nutrition.

The good news is that research shows algae based omega-3s will raise EPA & DHA levels in vegans, even at relatively low dose20Blood docosahexaenoic acid and eicosapentaenoic acid in vegans: Associations with age and gender and effects of an algal-derived omega-3 fatty acid supplement – Sarter et al. | 2014 | Clinical Nutrition.

A study showed their omega-3 index score went from 3.1 to 4.8 after 4 months of taking 172mg DHA & 82mg of EPA per day.

Below are a couple of algae based omega-3s, so you can see their cost per gram of EPA & DHAs:

Name Price Quantity Flavored? EPA/DHA $/gram
Nordic Naturals - Algae Omega $26 60 soft gels Sorbitol Sweetener $4.35 / $2.18
Source Naturals - Non-Fish Omega-3s $15 30 soft gels Sorbitol sweetener $5.44 / $2.72


Glutamine (aka L-Glutamine) is one of 20 amino acids (the building blocks of protein), and is naturally derived from food sources.

It can also be taken as a supplement, and Andrew has been taking it regularly since his college days for its immune-enhancing effects.

Specifically it can aid with intestinal health21The Roles of Glutamine in the Intestine and Its Implication in Intestinal Diseases | Kim et al. | 2017 | International Journal of Molecular Sciences, and is an important fuel for immune cells22Why Is L-Glutamine Metabolism Important to Cells of the Immune System in Health, Postinjury, Surgery or Infection? | Newsholme | 2001 | The Journal of Nutrition.

In Andrews podcast titled “Nutrients for Brain Health and Performance” (link), Andrew describes how glutamine can also be beneficial to the brain.

First, glutamine helps in offsetting sugar cravings by communicating with the brain via glutamine-sensing neurons in the mucosal lining of the gut. On picking up the presence of the amino acid glutamine, these neurons signal satiety and satisfaction.

Secondly, Andrew talks about the protective effect of glutamine on cognition in hypoxic conditions such as high altitudes or sleep apnea23The Possible Importance of Glutamine Supplementation to Mood and Cognition in Hypoxia from High Altitude | Quaresma et al. | 2020 | Nutrients Journal.

Good sources of gluatmine include beef, fish, eggs, dairy, cottage cheese as well as vegetables like beans, cabbage, spinach and parsely.

When supplementing, Andrew says that people use anywhere from 1 gram up to 10 grams per day (high dose). He says that he takes it regularly in small doses, but doesn’t mention the specific amount.

Sources of L-Gluatmine include include:


Whilst creatine is a well known supplement for bodybuilding, Andrew explains that he takes it primarily for its cognitive benefits.

Specifically for its ability to help modulate and support the brain networks involved in focus and concentration.

He takes 5 grams per day of creatine monohydrate – mixing the powder into whatever he is drinking at the time.

In terms of timing, he takes it in the morning, or after his workout, it depends when he remembers.

Reputable brands of creatine powder include:

PriceCost per 5g
Momentous – Creatine450 grams$31.41 with coupon$0.34
NOW – Creatine (Micronized)500 grams$25$0.25
Thorne – Creatine450 grams$38.00$0.42

Further Supplements Andrew Takes

Vitamin D

Vitamin D is essential to the human body and has a direct effect on the expression of more than 1,000 genes in most of our cells24Vitamin D: A Micronutrient Regulating Genes – Carsten Carlberg | 2019 | Current Pharmaceutical Design .

Andrew mentions in his interview with Rhonda Patrick (at 1:25:30) that he takes 5,000 to 10,000IU of vitamin D per day, and says his vitamin D levels are within range on blood tests.

It’s worth noting the multivitamin he takes, mentioned below, contains 1,500 IU (37.5 mcg) per serving (3 capsules).

Reputable brands include:

Athletic Greens

Athletic Greens is a brand of green powder that you mix with water and drink.

They’re a sponsor of Andrew’s podcast, and Andrew says he has been using them for over 12 years.

Citing the vitamins, minerals and probiotics as the reason he takes it once to twice per day.

The product was formerly called “Athletic Greens Ultimate Daily”, and now it’s called Athletic Greens AG1, or just AG1.

Perhaps the rebrand leads the way for an AG2 version?

Health influencer Rhonda Patrick was asked her thoughts on Athletic Greens in her May 2022 Q&A.

She noted it contains a blue green micro algae called spirulina, which is a potential source of a liver toxin called microcistins.

See FDA warning and a paper on mycocystins in dietary supplements.

Therefore she suggested to the subscriber who raised the question to contact Althetic Greens for their microcystin testing data.

To her knowledge the subscriber didn’t receive a reply containing data to allay this potential concern.

If any readers have this data from Athletic Greens it would be great if they could share.

Andrew explains in his Tools for managing Stress & Anxiety video that he occasionally uses Ashwagandha during stressful periods.

It’s a plant that grows natively on the Indian sub-continent, and has been used for >3,000 years in ayurvedic medicine for a variety of issues.

Andrew notes that there has been significant research confirming this effect, such as a randomized controlled trial that found a 20% reduction in cortisol, and a 40% reduction in perceived stress, compared to the placebo group25A prospective, randomized double-blind, placebo-controlled study of safety and efficacy of a high-concentration full-spectrum extract of ashwagandha root in reducing stress and anxiety in adults – Chandrasekhar et al. | 2012 | Indian Journal of Psychological Medicine.

^ Cortisol reduction results from an Ashwagandha Study

However, Andrew doesn’t like to take it chronically, and will stop after a few days, or max a week, and then go back to his normal routines. This is to avoid dependence and a build-up of tolerance.

^ Listen to podcast #10 in full here

In Andrew’s AMA #3 he comments on Ashwagandha dosage and timing for the purpose of reducing cortisol, saying:

Dosage: 250-300 mg in the early afternoon, and 250-300 mg again in the evening

Timing: Andrew suggests that we want our cortisol to remain naturally elevated in the mornings. Therefore he suggests delaying the first dose of Ashwagandha until the afternoon.

He also suggests to avoid taking Ashwagandha prior to exercise, on the basis that some of the beneficial adaptations to exercise come from the short spike in cortisol that exercise triggers. Therefore we don’t want to blunt it.

^ Listen to AMA #3 in full here

Examples of reputable brands include:


Andrew says that he takes a multivitamin once per day. Specifically one called Opti-Men by Optimum Nutrition.

Saying that he has been taking it for about 25 years, and it’s more a result of habit than recent research.

However, he says he checks his blood markers regularly, and it certainly doesn’t appear to be causing any harm.

Further Supplements Andrew Mentions

Cissus Quadrangularis

Andrew discusses cissus in the context of boosting serotonin.

Citing a study where participants took 300 mg of cissus quadrangularis for 6 weeks, and saw an increase in serotonin of ~30% versus placebo26The effect of Cissus quadrangularis (CQR-300) and a Cissus formulation (CORE) on obesity and obesity-induced oxidative stress – Oben et al. (2007) | Lipids in Health and Disease.

The study was in the context of weight loss, and Andrew mentions that it should come as no surprise that an increase in serotonin can aid with weight loss.

^ Clip from podcast episode #80 – from 1hr 53m 30

Cissus Quadrangularis is a succulent plant from the grape family that is native to parts of Asia and Africa.

It’s used in traditional medicine for a variety of ailments.

Andrew mentions this supplement for interest, but doesn’t say that he takes it personally.

Brands selling cissus include:


Whilst Andrew doesn’t take nicotine, and doesn’t recommend taking it, he has discussed it on multiple podcasts, so thought it worth a mention.

We’re all familiar with nicotine as the addictive chemical in cigarettes.

It’s also now available in other forms such as patches, vapes, gum and lozenges.

Andrew notes that Nicotine can aid with focus and concentraction.

With the effect due to it binding with the nicotinic acetylcholine receptors, which then trigger downstream release of dopamine and norephiphrine neurotransmitters:

He also tells an anecdotal story about a Nobel Prize winning friend who chews large amounts of nicorette gum, believing it helps with his focus (see audio clip below).

Similarly, Andrew’s friend Peter Attia tells how he has used nicorette gum and lozenges off and on for 10 years to aid with focus and concentration:

Peter notes that whilst Nicotine is addictive, he doesn’t personally find it addictive and regularly takes effortless breaks.

He said that he got some slack when he did an “Ask Me Anything” podcast on Nicotine and disclosed that he uses it.

However, he feels that the risk from nicotine gum and lozenges is far less than prescription stimulants such as ritalin and adderall, which have become popular in the US.

He explains that cigarettes contain about 1mg of nicotine each, whereas many nicotine gums and lozenges contain 4 mg or more. Which are large doses for people unaccustomed to nicotine.

Andrew asked sleep expert Matthew Walker on Twitter what effect nicotine has on sleep. He replied saying nicotine disrupts sleep significantly, specifically it:

  • Increases light stage 1 and stage 2 NREM
  • Increases the amount of time you are awake at night
  • Decreases the amount of deep NREM sleep

Citing this study.

Anyone considering trying nicotine should keep in mind its addictive properties, and note that it does raise heart rate and blood pressure temporarily27Nicotine and sympathetic neurotransmission – Haass & Kübler | 1997 | Cardiovascular Drugs and Therapy Journal , important to know for people with high blood pressure or other cardiovascular issues.

Examples of reputable brands of lozenges include:

Rhodiola Rosea

Whilst Andrew doesn’t take the herb based supplement Rhodiola Rosea, in his interview with Dr Layne Norton, Layne mentions two supplements he’s particularly a fan of 1) Creatine (which we discussed above) and 2) Rhodiola Rosea.

Layne mentions Rhodiola has a few benefits, including:

  • Reducing physical fatigue
  • Potentially enhancing memory and cognition

He likes to take it with caffeine, finding that it smoothes out the experience, making it more pleasant.

Additionally he’s found it helps mitigate caffeine withdrawal side effects.

In a post on Layne’s Instagram, he discusses dosage details, saying:

  • The Rhodiola extract should contain 3% rosavins and 1% salidroside.
  • It’s best to take on an empty stomach, but not close to bedtime, due to its slight stimulant effect.
  • In terms of dosage, amounts as low as 50 mg have been found to reduce fatigue, with 680 mg being the suggested upper limit, due to a bell-curve effect.

This info on dosages appears to come directly from’s Rhodiola page, which Layne credits at the bottom of the Instagram post.

Example brands of Rhodiola include:

Supplements Andrew Avoids

Interestingly, Andrew avoids some popular sleep supplements, so I’ve summarized them below:


  • Whilst Melatonin is one of the most popular sleep supplements on the market, Andrew personally avoids it.
  • He explains this is due to its affects on sex steroid hormones – the pathways related to testosterone and estrogen, and not wanting to interfere with them.
  • He discussed with sleep expert Matthew Walker how a recent meta-analysis, in healthy (not older age) adults showed melatonin only increases sleep time, by on average, 3.9 minutes, and efficiency by ~2%.
  • In that discussion, Matthew suggests the most robust benefits are seen in the 60+ age range. Aging can cause calcification of the pineal gland, which decreases melatonin release – making supplementation more beneficial.

Andrew discusses these points with Matthew Walker from 1hr 36m of their podcast together (link).

5-HTP, Tryptophan & Serotonin

  • Andrew personally finds that with 5-HTP, tryptophan (serotonin precursors), and serotonin itself, he falls asleep easily, has vivid dreams, then wakes up wide awake about 3 hours later.
  • This then negatively affects his sleep for several days after.

Tracking & Measuring His Health

Andrew explains that he tests his blood twice per year in order to track and monitor his health.

This helps him to monitor the effect supplements are having on him. For example when he added Tongkat Ali and Fadogia Agrestis to boost his testosterone, he already had a baseline reading from previous blood tests. He was then able to test himself after using the supplements, to measure how they had impacted his testosterone and other hormones.

One company he has specifically mentioned for blood tests are Inside Tracker – who are also a show sponsor of his podcast.

InsideTracker offer 2 main blood tests:
