Six compounds Huberman highlights as supporting neuron structure and cognitive function, each with specific dietary sources and (where applicable) supplementation dosing thresholds. Distinct from general Daily Protein Intake Guidelines — these are function-specific micronutrients/precursors, not macronutrient targets.
Structural fats that make up neuron membranes (double-layered lipid structures governing electrical activity); most people under-consume omega-3 relative to omega-6. Target: at least 1.5g/day, ideally 2–3g/day EPA. Sources: fish (primary), chia seeds, walnuts, soybeans (plant sources), or supplementation if fish intake is low.
Supports neuronal function directly. Abundant in meat and fish; available as an inexpensive supplement mimicking the food-derived form at higher concentration.
Feeds biosynthesis of acetylcholine, the neuromodulator described as the basis of focus/concentration. Target: 500mg–1,000mg/day. Primary source: eggs (yolks); alpha-GPC as a supplement alternative.
Peer-reviewed research shows it improves neuronal/brain function and fuels frontal cortical circuits tied to mood and motivation — not just a muscle-performance compound. Minimum 5g/day, recommended as a baseline regardless of dietary meat intake.
Found in dark-skinned berries (blueberries, blackberries, black currants). Data links them to improved brain function; mechanism unclear (direct neuronal effect vs. inflammation reduction). Recommendation: a cup or two fairly often.
Emerging evidence for offsetting sugar cravings via gut glutamine-sensing neurons that signal satiation to the brain. Range: 1–10g/day (consult a physician first). Sources: meat, dairy, cottage cheese, beans, cabbage, spinach, parsley.
All six are obtainable from food; supplementation is optional, meant to reach higher levels rather than being required. Huberman discloses he personally relies on EPA, creatine, and alpha-GPC supplementation as a "baseline insurance policy" despite not actively eating much fish or seeking dietary creatine.

Creatine's brain/cognitive benefits are concentrated in metabolically or cognitively stressed populations (sleep deprivation, hypoxia, jetlag, aging 60+) and reportedly require substantially higher doses than the standard 5g/day muscle protocol — closer to 20g/day for at least a week in the best available studies. The likely bottleneck is the blood-brain barrier: astrocytes guarding the barrier appear to have limited/no creatine transporter expression (unlike the blood-side endothelial cells), so low blood creatine levels from a 5g dose may not reach the brain effectively. See Creatine Supplementation for full detail, evidence-quality caveats, and mechanism.
Creatine is a case study in dosing thresholds mattering more than compound choice: it crosses the blood-brain barrier, but at the standard 5g/day muscle tissue preferentially consumes it first, so brain-relevant effects may require doses well above 5g (10-20g/day in cited protocols). Unlike most brain-support compounds discussed for general use, its proposed benefit is stress-conditional — surfacing under sleep deprivation, psychological stress, aging, or neurodegenerative disease rather than at baseline.
