The Sleep Toolkit
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.
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
Dim and shift your light after sunset
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.
Cool the room and drop your core temperature
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.
Time caffeine and limit alcohol
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.
Use NSDR or self-hypnosis to fall (back) asleep
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.
Magnesium Threonate
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.
Apigenin
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.
L-Theanine
Promotes alpha brain waves and quiets mental chatter. Start low. Skip theanine if you get overly intense dreams, sleep-walk or have night terrors.
Occasional extras for tough nights
He adds these only intermittently, not nightly, to avoid building a routine around them. Treat as occasional support, layered one at a time.
- 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
- 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.
