Expert Positions
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.
Where They Disagree
Johnson eliminates caffeine entirely from his Blueprint protocol to maintain emotional stability and protect sleep, while Huberman and Patrick actively recommend daily or near-daily caffeine consumption as a performance and longevity tool.
Hyman lists caffeine alongside sugar, alcohol, and nicotine as substances that negatively impact brain function and recommends elimination during health reset protocols, while Huberman highlights caffeine's neuroprotective effects and dopamine receptor upregulation.
