Timing Protocol
When to Take Sleep Optimization — Expert Timing Protocols
Expert-analyzed timing recommendations for sleep optimization based on what 5 longevity researchers say about when, how, and what to take it with.
Quick Timing Guide
Take sleep supplements 30-60 minutes before bed. Delay caffeine 90-120 minutes after waking (Huberman). Last meal 3+ hours before bed (Johnson, Hyman). Stop liquids around 4 PM for uninterrupted sleep (Johnson). Wind-down routine 30-60 minutes before bed with no screens.

Full Protocol
Timing
Take sleep supplements 30-60 minutes before bed. Delay caffeine 90-120 minutes after waking (Huberman). Last meal 3+ hours before bed (Johnson, Hyman). Stop liquids around 4 PM for uninterrupted sleep (Johnson). Wind-down routine 30-60 minutes before bed with no screens.
Dosage
Magnesium threonate 145mg + Apigenin 50mg + L-theanine 100-400mg (Huberman's sleep cocktail). Optional: Glycine 2g, GABA 100mg, or Myo-inositol 900mg for middle-of-night waking.
Form
Magnesium threonate or bisglycinate for sleep support (threonate crosses the blood-brain barrier). Apigenin derived from chamomile. Theanine as L-theanine. Hyman also recommends valerian root and glycine.
Notes
Huberman cautions that theanine may cause excessively vivid dreams in some people and should be reduced or eliminated if this occurs. Melatonin is generally not recommended by Huberman or Walker for healthy adults — it provides minimal benefit (only a few extra minutes of sleep) and doses sold commercially are often supra-physiological. Attia notes melatonin can aid sleep initiation in older adults. Johnson uses melatonin specifically for jet lag recovery. All experts agree that behavioral interventions (light, temperature, consistency) should be prioritized over supplements.

Important Notes
Huberman cautions that theanine may cause excessively vivid dreams in some people and should be reduced or eliminated if this occurs. Melatonin is generally not recommended by Huberman or Walker for healthy adults — it provides minimal benefit (only a few extra minutes of sleep) and doses sold commercially are often supra-physiological.

Where Experts Disagree
- Huberman provides specific supplement dosages and recommends the mag threonate + apigenin + theanine stack, while Attia and Walker emphasize that foundational sleep behaviors should come first and supplements are secondary.
- Johnson advocates an 8:30 PM bedtime and building your entire social life around sleep, which is far more extreme than other experts who recommend consistency without such rigid scheduling.
- Hyman emphasizes EMF reduction (turning off Wi-Fi at night) as a sleep hygiene factor, which is not supported or mentioned by the other four experts.
