What’s your sleep stack?

The sleep stack is magnesium threonate, apigenin, and theanine; Huberman sometimes adds glycine, GABA, and myo-inositol. 1 2

• 1. Doses and timing: 145 mg magnesium threonate, 50 mg apigenin, and 100–400 mg theanine, taken 30–60 minutes before bed. He says taking them when you haven’t eaten for about three hours beforehand is ideal. 3 4
• 2. Possible downsides: Magnesium threonate causes gut discomfort for about 5% of people; theanine can cause vivid, disruptive dreams for some. 5
• 3. Occasional additions: He sometimes takes 2 g glycine and 100 mg GABA every third or fourth night. 6
• 4. Myo-inositol: He takes 900 mg every other night, on nights he isn’t taking glycine and GABA, and finds it helps him fall asleep and return to sleep after waking. 7
