Molecules Matter With Dr. Dan
Dr. Dan Gubler 26 episodes Oct 27, 2026
Molecules Matter with Dr. Dan is a science-based podcast that investigates how specific molecules found in plants, fungi, and foods influence human health. Each episode focuses on a single molecule or class of molecules, covering its natural origins, why organisms produce it, and its effects on human biology. Grounded in peer-reviewed research, the show aims to separate scientific mechanism from marketing hype, replacing wellness noise with a molecular understanding of health. It is hosted by Dr. Dan Gubler and available via Substack.
