The Verdict

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.
