Longevity & AgingHow Urolithin A Clears Dying Mitochondria to Slow Your Aging
This episode dives into mitophagy — the cellular cleanup process that removes worn-out mitochondria and replaces them with healthier ones. Dr. Anurag Singh, Chief Medical Officer at Timeline Nutrition, explains how urolithin A, a postbiotic compound produced when gut bacteria process pomegranates and berries, activates this process. Clinical trials show urolithin A can improve muscle strength, endurance, immune resilience, and possibly cognitive function. Singh also covers how aging immune cells called T cells predict biological age, and how lifestyle factors like exercise, fasting, sleep, and diet work alongside urolithin A to build a more resilient body. The conversation includes practical guidance on dosing, delivery formats, and blood tests that can reveal your urolithin A status.
