Andrew Huberman on L-Theanine
16 episodes · 29 references · 2021–2025
- Huberman takes theanine nightly as part of his "sleep stack" (magnesium threonate + apigenin + theanine) at 100–200 mg, 30–60 minutes before bed - He highlights two primary benefits: enhancing sleep onset/depth via GABA pathway activation, and reducing caffeine jitteriness when paired with stimulants - He consistently warns that theanine causes vivid dreams in some people and is problematic for sleepwalkers; no evidence of recommending against use or stopping
Consumption
- Takes 100–200 mg of theanine as part of his nightly sleep stack with magnesium threonate and apigenin - Doses 30–60 minutes before bedtime to help "turn off my mind and fall asleep" - Sometimes takes theanine in the late afternoon during periods of high stress
Benefits
- Activates GABA pathways and chloride channels to reduce neural activity, quieting rumination and enabling faster sleep onset - Reduces jitteriness from caffeine — widely added to energy drinks and coffee products for this reason - Shown to significantly increase relaxation in chronically stressed or anxious individuals
Best Practices
- Effective dose range is 100–400 mg, with 100–200 mg most commonly recommended for sleep - Take 30–60 minutes before bedtime, alone or combined with magnesium threonate and apigenin - 100 mg can also be taken alongside caffeine during the day to offset stimulant jitteriness
Cautions
- Can cause vivid dreams intense enough to wake people up, even at the lowest 100 mg dose - Sleepwalkers and those with night terrors should avoid theanine due to dream intensification - Combined with magnesium, may cause excessively deep sleep making it hard to wake up in the morning
“My existing toolkit for sleep... consists of magnesium threonate, apigenin, and theanine.”

AMA #2: Improve Sleep, Reduce Sugar Cravings, Optimal Protein Intake, Stretching Frequency & More
“This is one reason why I supplement theanine for sleep. But if I'm feeling like I've been under a lot of stress and I'm not managing it well, I might start taking a little bit of theanine, especially in the late afternoon.”

“Theanine has also been shown for people that are chronically anxious or chronically stressed to significantly increase relaxation.”

“Theanine is a compound that can also increase GABA but also increases activation of something called chloride channels. Chloride channels are another way in which neurons lower their levels of activity.”

“The reason why a lot of energy drinks and sodas and frankly now coffee brands are including theanine is because it tends to have a mild anxiety-reducing effect and it reduces the jitters that caffeine creates.”
AMA #8: Balancing Caffeine, Decision Fatigue & Social Isolation
“Theanine activates certain GABA pathways which are involved in turning off top-down processing and thinking, making it easier to fall asleep.”
How to Defeat Jet Lag, Shift Work & Sleeplessness
“Many people opt to take 100 milligrams of theanine as a way to offset some of that jitteriness associated with caffeine-containing beverages or foods.”
Using Caffeine to Optimize Mental & Physical Performance
“...100 milligrams to 300 milligrams of theanine has a calming effect.”
How to Defeat Jet Lag, Shift Work & Sleeplessness
“I recommend taking magnesium and theanine 30 to 60 minutes before bedtime, with or without food.”
