The Active Site
The Active Site investigates the biology, biochemistry, and clinical evidence behind nutrition, health, and human performance. Hosted by Dr. William Wallace, PhD, with a decade in clinical research and natural product engineering. Episodes are investigations, not always verdicts. We often examine studies in isolation (sometimes alarming, sometimes promising) to show how a single finding builds a certain belief, then re-contextualize within the broader body of evidence. Some episodes trace a question across decades of research. Some examine a single paper in depth. Watch or listen to the end. T...
