Andrew Huberman Sleep Cocktail (Updated 2026)

As of 2026, Huberman says he exclusively takes the AGZ sleep supplement at night.

In this article we’ll briefly look at AGZ, then cover the sleep supplements he talked about prior to this brand collaboration.

AGZ

Huberman has a long standing relationship with AG1, and he was involved in the creation of their sleep supplement; AGZ.

In advertising segments on his show he says that AGZ is the only sleep supplement he takes, and it’s helped improve his deep and REM sleep.

AGZ is a blend of many compounds that are associated with improved sleep, including many Huberman has previously discussed:

Magnesium (as L-Threonate + Glycinate) – 250mg
L-Theanine – 200mg
Glycine – 2g
Myo-inositol – 1g

For the full list of ingredients, see the nutritional insert.

Prior Supplements

Prior to taking AGZ, Huberman discussed a range of supplements that have evidence for aiding sleep. Broadly speaking, these could be broken into the two stacks below:

Stack One (nightly)

Supplement	Dose / Notes
Magnesium L-Threonate	140 mg nightly
Theanine	100 – 300 mg nightly
Apigenin	50 mg nightly
Inositol	900 mg nightly

Stack Two (3–4 nights/week as needed)

Supplement	Dose / Notes
GABA	100 mg
Glycine	2 grams

Whilst Andrew hopes that most people will fall asleep without assistance, for those who don’t, he suggests there is a middle ground between taking nothing and taking sleeping pills.

The previous combination that worked for him (and many others) was Magnesium, Theanine and Apigenin – which he discusses in the clip below:

^ A clip from Episode 28 of Andrew’s podcast

Combo 1 – Magnesium, Theanine & Apigenin, Inositol

Magnesium Threonate

Magnesium is very important to the human body, and is involved in over 600 enzymatic reactions¹.

Specific to sleep, magnesium supplementation can activate the parasympathetic nervous system², 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 Americans³, supplementing it can have a noticeable effect on sleep.

Andrew personally prefers the Threonate form (also known as L-Threonate), but notes that 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

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 bis-glycinate, 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:

Product	Servings	Cost per 100 mg
Momentous - L-Threonate	30 x 144 mg	$1.16
Nutricost - L-Threonate	30 * 150 mg	$1.10
Life Extension - L-Threonate	50 x 144 mg	$0.71

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 L-Threonate

Magnesium Glycinate is another good source of magnesium that is noticeably more affordable (see cost per 100 mg). Reputable brands include:

Product	Capsules	Price	Cost per 100 mg*
Nutricost - Mag. Glycinate	360 x 70 mg	$22	$0.09
Life Extension - Mag. Glycinate	90 x 105 mg	$18	$0.19
California Gold Nutrition - Mag. Glycinate	180 x 133 mg	$25 exc. coupon	$0.10

Theanine

Theanine, which is an amino acid found in tea, can have calming effects when supplemented⁴.

One of the ways it does this is to increase “alpha brain waves” – a type of brain wave that is associated with calm and relaxation⁵.

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:

Product	Capsules	Price	Cost per 100mg
NOW – Theanine	120 x 200mg	$20	$0.08
Nutricost – Theanine	240 x 200 mg	$20	$0.04
Momentous – Theanine	60 x 200mg	$40	$0.33

Huberman’s Dose: 100 – 300 mg

Apigenin

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.

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:

Momentous – Apigenin – 50 mg
Swanson – Apigenin – 50 mg (see 20% off iHerb coupon)
Nutricost – Apigenin – 50 mg

Andrew’s Dose: 50mg

Inositol

Huberman occasionally takes 900 mg of Myo-Inositol along with his sleep stack of Magnesium, L-Theanine and Apigenin.

Saying that he has noticed an improvement in his sleep since taking it, specifically in terms of waking up in the middle of the night, and then being able to fall asleep more quickly again.

^ 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 involved⁶.

To clear up some potential confusion on inositol naming, there are 3 common inositol supplements:

Myo-inositol (the type Huberman takes)
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:

Momentous – Inositol – 900 mg per capsule
Nutricost – Inositol – 500 mg per capsule
Jarrow Formulas – Inositol – 750 mg per capsule (see 20% off iHerb coupon)

Combo 2 – GABA & Glycine

^ Clip from Tim Ferriss interview (link)

Huberman 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 barrier⁷. Whether it does or does not, it may also act on the peripheral nervous system through the gut-brain axis⁸.

Glycine is a non-essential amino acid, abundant in animal products. It’s thought to improve sleep by helping to reduce the core body temperature⁹. In another study, 3 grams of Glycine before bed improved subjective sleep quality and sleep efficacy. Then objectively, using polysomnogram to measure, they found glycine reduced latency to sleep onset and latency to slow wave sleep¹⁰.

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:

Product	Price per 500 mg
Thorne – GABA – 250 mg capsules	$2.00
Solaray - GABA - 100 mg capsules	$3.00
Nutricost - GABA - 500 mg capsules	$0.07

Examples of Glycine brands include:

NOW – Glycine – 1,000 mg capsules (see 20% off iHerb coupon)

Roundup

Above we looked at 2 different combinations of supplements you can use for improving sleep quality, without having to resort to sleeping pills.

It makes sense to start by looking at combo #1 – as it’s possible that the addition of just Magnesium and either Theanine or Apigenin will be enough.

Personally I don’t like to add a whole lot of supplements to my daily routine in one go. So I’d start by adding Magnesium (then understand the effect), add Theanine (again, understand effect), Apigenin then Inositol.

That way it’s easier to know if any of them do not agree with your body.

If those didn’t work for you, then it could be worth moving on to combo #2 – and experimenting with GABA & Glycine.

Hopefully the above helps. If you have any questions or comments, please leave them below.
