Goal-Based Guide
Sustained focus depends on brain energy, neurotransmitter balance, and adequate sleep. These are the supplements with the strongest expert evidence for cognitive performance.
All 5 experts actively recommend omega-3 supplementation, making this one of the strongest consensus topics. Patrick and Attia provide the deepest mechanistic coverage, Huberman recommends 1-3g EPA for mood and cognition, Hyman lists omega-3 as a foundational supplement everyone needs, and Johnson includes omega-3 sources in his Blueprint diet.
All 5 experts actively recommend creatine supplementation. Huberman, Attia, and Patrick are the strongest advocates, each featuring dedicated deep dives on creatine's benefits for both physical performance and cognitive function. Johnson includes creatine in his Blueprint longevity stack. Hyman recommends it as one of his six essential daily supplements for muscle mass, insulin sensitivity, and brain health.
All 5 experts acknowledge caffeine as a potent performance enhancer and cognitive tool, but they diverge significantly on whether it belongs in a longevity protocol. Huberman and Patrick are the strongest advocates, each dedicating deep coverage to caffeine's mechanisms, dosing, and health benefits. Attia views caffeine as a reliable ergogenic aid but emphasizes strict timing to protect sleep. Johnson actively avoids caffeine entirely as part of his Blueprint protocol. Hyman frames caffeine as a crutch that masks underlying health issues and recommends elimination during reset protocols.
Daily foundations for sustained focus and mental clarity:
Relying on caffeine without addressing sleep. Attia notes caffeine reduces deep sleep by 20%.
Taking nootropics before optimizing foundational supplements (omega-3, creatine, magnesium, vitamin D).
Not delaying morning caffeine. Huberman says waiting 90-120 minutes prevents afternoon crashes.
Using Huberman's every-other-day caffeine protocol without testing it first — it can cause withdrawal headaches.
