Join me, Dr. Mike T. Nelson, on the Flex Diet Podcast as I sit down with Dr. Jeremy Townsend to explore the fascinating world of adaptogens. We’re diving deep into how compounds like Rhodiola rosea, ashwagandha, and eleuthero can enhance performance, support muscle growth, and improve body composition—all without compromising overall health.

Throughout our conversation, we discuss what the research says about these powerful herbs, including how they influence stress resilience, recovery, and athletic performance. Dr. Townsend also unpacks the science behind optimal dosages, potential mental and physical stress effects, and the nuances of using adaptogens effectively. Beyond that, we discuss the often-overlooked role of micronutrition in maximizing performance and overall well-being, an area that too many athletes neglect.

We also touch on how AG1 contributes to the field of nutritional science and why paying attention to the right vitamins and minerals can make a measurable difference in training outcomes.
