Burning Questions
Viewers crave a mechanistic understanding of caffeine’s impact on dopamine: how receptor sensitivity changes over time, what “tolerance” really means, and how to cycle caffeine without crashes or withdrawal. Many ask why to delay caffeine 90–120 minutes after waking and how that relates to cortisol and adenosine.
Others compare sources and dosing—coffee vs matcha vs yerba mate—and seek help for special cases like shift work, diabetes, and GERD. They want clear, evidence-based protocols for timing caffeine around workouts, study sessions, and sleep.

Most comments praise the episode’s clarity and practical dosing advice—from the 1–3 mg/kg range to the morning delay rule. Viewers felt empowered to apply these tools to their daily routines and appreciated the blend of science and actionable protocols typical of Huberman’s style.
Still, some called for more balance—asking for coverage of anxiety, heart effects, thyroid impact, and genetic factors. Others requested shorter recaps and additional topics such as nootropics, meditation, and nutrient timing. Overall, feedback was constructive and solution-oriented.
