Could *This* Molecule Be the KEY To Reversing Immune Aging & “Supercharging” Your Mitochondria? With Dr. Anurag Singh

Full Show Notes: https://bengreenfieldlife.com/timelinereplay

In this special replay episode with repeat guest Dr. Anurag Singh from Timeline Nutrition, you'll explore the science of cellular health and longevity, including why mitochondrial function affects everything from energy and muscle performance to cognitive clarity and how well you age. Dr. Singh explains how urolithin A, a postbiotic compound derived from foods like pomegranates and berries, activates mitophagy, the body's cellular clean-up system that clears out worn-out mitochondria and replaces them with new ones, and how clinical research shows it can support muscle strength, endurance, immune resilience, and cognitive function. You'll also hear how diet, gut health, exercise, sleep, and recovery work alongside urolithin A to build a stronger, more resilient physiology over time.

Dr. Anurag Singh is Chief Medical Officer at Timeline Nutrition, with an M.D. in internal medicine and a Ph.D. in immunology. He has authored more than 50 scientific articles, been awarded over 20 patents, and led more than 50 randomized clinical trials. His decade of research on urolithin A has produced multiple clinically validated products bringing longevity science directly to consumers.
