Huberman's framework starts with light exposure and circadian biology, then layers in supplements that modulate neurotransmitter systems. We examine the evidence.
Andrew Huberman is a Stanford neuroscientist whose Huberman Lab podcast has introduced millions of people to the science of light, sleep, and neuroplasticity. His protocol emphasises free, non-supplemental interventions — morning sunlight, cold exposure, deliberate heat — before any supplement is considered.
Huberman's most-cited recommendation is morning sunlight exposure: 10–30 minutes of outdoor light within an hour of waking, without sunglasses. Morning light advances the circadian phase, suppresses residual melatonin, and sets the cortisol pulse that drives alertness. The evidence base is Tier I for circadian entrainment and sleep quality.
Key items: magnesium L-threonate or bisglycinate (300–400 mg before bed), apigenin (50 mg), theanine (100–300 mg), alpha-GPC (300 mg), and ashwagandha KSM-66 (600 mg). He also discusses creatine (5 g/day), omega-3s, and vitamin D3.
Vitaei verdict
Huberman's free-intervention-first approach is excellent. His supplement stack is neuroscience-focused rather than longevity-focused per se. The strongest items are magnesium (Tier I for sleep), ashwagandha KSM-66 (Tier II for cortisol), and alpha-GPC (Tier II for cognition).
