In this episode, I explain the biological roles of the four major neuromodulatorsפopamine, epinephrine (aka adrenaline), serotonin, and acetylcholineסnd describe how these neuromodulators impact a wide variety of mental states and behaviors, including focus, creativity, motivation, drive, learning, alertness, mood, relationships, and feelings of well-being. Then, with that foundational understanding in mind, I describe a potent toolkit of science-supported behavioral, nutrition, and supplementation tools that can be used to increase baseline levels of individual neuromodulators and that can be modified for specific goals. This episode summarizes low-or-no-cost, actionable, science-based tools that can benefit anyone in order to enhance their levels of brain chemicals and improve mental health, physical health, and performance.
