#390: Muscle, Mitophagy, and Longevity: How Urolithin A Supports Healthy Aging and Athletic Performance With Brad Currier, PhD

Today, I'm joined by Dr. Brad Currier, Manager of Clinical Trials at Timeline Nutrition and an expert in the world of muscle and aging research. Brad is on the cutting edge of mitochondrial science, and in this episode, he helps us unravel the mysteries of why some 80-year-olds are still crushing it in the gym while others struggle to get up the stairs. We dive into his fascinating research on mitophagy—our bodies' system for recycling dysfunctional mitochondria—and what it means for muscle health, strength, and vibrant aging.
