This episode serves as a sort of “Dopamine Masterclass”. I discuss the immensely powerful chemical that we all make in our brain and body: dopamine. I describe what it does and the neural circuits involved. I explain dopamine peaks and baselines, and the cell biology of dopamine depletion. I include 14 tools for how to control your dopamine release for sake of motivation, focus, avoiding and combating addiction and depression, and I explain why dopamine stacking with chemicals and behaviors inevitably leads to states of underwhelm and poor performance. I explain how to achieve sustained increases in baseline dopamine, compounds that injure and protect dopamine neurons including caffeine from specific sources. I describe non-prescription supplements for increasing dopamine—both their benefits and risks—and synergy of pro-dopamine supplements with those that increase acetylcholine.
