The Verdict
All 5 experts treat sleep as the single most important pillar of health and longevity. Huberman provides the most actionable supplement and behavioral protocols, Attia and Walker quantify the disease risk of poor sleep, Johnson builds his entire life around sleep metrics, Patrick connects sleep to cellular repair and brain health, and Hyman addresses root-cause disruptors through a functional medicine lens.
Quick Protocol
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.
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.
Key Findings
- Sleep deprivation causes a 70% drop in natural killer cell activity after just one night of four hours of sleep, directly impairing cancer defense (Walker/Attia).
- One night of disrupted deep sleep leads to immediate, measurable increases in beta-amyloid and tau proteins in cerebrospinal fluid — the hallmarks of Alzheimer's disease (Walker/Attia).
- Daylight savings time data shows a 24% increase in heart attacks when losing one hour of sleep in spring, and a 21% decrease when gaining an hour in fall (Walker/Attia).
- Morning sunlight exposure within 30-60 minutes of waking triggers a cortisol pulse that sets the circadian clock and times melatonin release 12-14 hours later (Huberman, Johnson, Patrick, Hyman).
