How Urolithin A Boosts Muscle, Immune Function, and Brain Health | Dr. Anurag Singh

Dr. Anurag Singh, Chief Scientific Officer at Timeline Nutrition joins Modern Healthspan for an in-depth conversation about urolithin A and the science of mitophagy, the cellular process that cleans out damaged mitochondria.

We explore the clinical evidence from multiple human trials: the ATLAS trial showing 12% muscle strength gains and 10% VO2 max improvements in sedentary middle-aged adults, independent studies in elite athletes demonstrating enhanced recovery and performance, and the groundbreaking MitoImmune trial published in Nature Aging revealing 20% increases in immune cell mitochondria in just 28 days.

Dr. Singh provides practical guidance on dosing (500mg vs 1000mg), timing, and who benefits most from supplementation. We discuss why only 30% of people can produce urolithin A naturally from foods like pomegranates and berries, and how direct supplementation overcomes this limitation.

Looking ahead, we cover Timeline's Healthspan XPrize semi-finalist status, ongoing blood-brain barrier research setting the stage for brain health trials, and Dr. Singh's vision for combining mitophagy activation with emerging therapies like mitochondrial transplantation. He also shares why he believes mitochondrial dysfunction is "the mother of all hallmarks of aging."

Whether you're interested in the science of healthy aging, considering urolithin A supplementation, or want to understand the future of longevity medicine, this comprehensive conversation provides the evidence and insights you need.

Topics covered:

• What urolithin A is and how mitophagy works

• ATLAS trial results: muscle, endurance, and inflammation

• MitoImmune trial: immune system rejuvenation

• Practical supplementation guide

• Brain health research and future directions

• The role of mitochondrial health in aging
