The Sleep Toolkit

Updated July 8, 2026

Andrew Huberman's Sleep Toolkit puts behavior first: light exposure, cooling core temperature, and timing caffeine and alcohol. Only then does it add a small, optional supplement 'cocktail' of magnesium threonate, theanine and apigenin. A 1-to-3-degree drop in core temperature helps you fall and stay asleep; add supplements one at a time, since some people need none at all.

What it is

This is Huberman's complete approach to sleep from his dedicated Sleep Toolkit episode and newsletter. The order matters: behaviour does most of the work (light, temperature, timing of caffeine and alcohol), and a small supplement 'cocktail' is the finishing layer, not the foundation. He is explicit that you should add supplements one at a time to learn what actually helps you, and that some people need none at all.

Why it worksâ–¼
Sleep is gated by your circadian clock and your core body temperature. Morning and evening light set the clock; a drop of 1 to 3 degrees in core temperature lets you fall and stay asleep, which is why a hot bath or sauna earlier and a cool room at night both help. Caffeine blocks adenosine (the sleepiness signal) for hours, and alcohol fragments sleep architecture. The supplement layer is mechanistic too: magnesium threonate and theanine quiet an overactive mind, and apigenin (from chamomile) nudges GABA, together helping you fall asleep faster and reach deeper sleep.

Clinical strong human trials Mixed some or emerging evidence Commercial weak or unproven, sold widely Equipment / Test not an evidence claim How we grade →
Evening

Dim and shift your light after sunset

Dim overhead lights; avoid bright light 10pm to 4am

Bright overhead light in the evening suppresses melatonin and pushes your clock later. Use dim, low-placed lighting at night and get some sunset light when you can.

Evening

Cool the room and drop your core temperature

Sleep environment ~65 to 68°F; optional hot bath/sauna 1 to 2h before bed

You need a 1 to 3 degree drop in core temperature to fall asleep. A cool room helps directly; a hot bath or sauna earlier helps by triggering a rebound cool-down afterwards.

Cooling mattress topper
Keeps the bed cool through the night, optional
Daytime

Time caffeine and limit alcohol

Last caffeine ~8 to 10 hours before bed; minimise alcohol and THC

Caffeine's half-life means an afternoon coffee is still active at bedtime. Alcohol and THC may help you fall asleep but fragment sleep quality and REM.

Wind-down

Use NSDR or self-hypnosis to fall (back) asleep

10 to 20 min NSDR / yoga nidra if you wake at night or can't drop off

Non-sleep deep rest teaches your nervous system to downshift and is his go-to for getting back to sleep without lying there frustrated. Free on YouTube and via Reveri.

Cocktail

Magnesium Threonate

145mg, 30 to 60 min before bed (or 200mg magnesium bisglycinate)

The base of his sleep cocktail. Threonate crosses into the brain well; bisglycinate is a cheaper, well-tolerated alternative. Roughly 5% of people get an upset stomach from magnesium, in which case skip it.

For this stepClinical
Magnesium L-threonate
145mg before bed; bisglycinate is a cheaper swap
Cocktail

Apigenin

50mg, 30 to 60 min before bed

A chamomile-derived compound that nudges GABA for a calm, non-sedating wind-down. Evidence is lighter than for magnesium or theanine, so it sits in the optional/mixed tier.

Huberman Lab
For this stepMixed
Apigenin
50mg before bed, chamomile-derived
Cocktail

L-Theanine

Start 100mg; increase to 200 to 400mg if needed

Promotes alpha brain waves and quiets mental chatter. Start low. Skip theanine if you get overly intense dreams, sleep-walk or have night terrors.

Huberman Lab
For this stepMixed
L-theanine
Start at 100mg; skip if vivid dreams or sleepwalking
Optional

Occasional extras for tough nights

2g glycine + 100mg GABA, or 900mg myo-inositol, every 3rd or 4th night

He adds these only intermittently, not nightly, to avoid building a routine around them. Treat as occasional support, layered one at a time.

Is this for you?
Good fit if
  • Anyone who wants behaviour-first sleep tools, not just pills
  • People who haven't fixed light, temperature and caffeine timing yet
  • Those who want to test supplements one at a time
  • Shift workers and travellers adapting their sleep
Cautions
  • Behaviour first. The light, temperature and caffeine-timing steps do most of the work; the supplements are a finishing layer and some people need none.
  • Add one supplement at a time so you can tell what actually helps you.
  • Skip L-theanine if you get overly intense dreams, sleep-walk or have night terrors. About 5% of people get GI upset from magnesium; if so, stop it.
  • Huberman advises against routine high-dose melatonin, citing possible effects on hormones; it is not part of this stack.
  • Check supplements against any medications or conditions with your physician, and buy third-party-tested products.
