Urolithin A (Mitopure) and Mitochondrial Renewal--Muscle, Immune, and Skin Benefits: Jen Scheinman, MS, RDN, CDN, Director of Science Communications at
Timeline details urolithin A and Timeline’s branded supplement Mitopure. She describes urolithin A’s discovery through pomegranate research and worm studies showing a 45% lifespan increase. She discusses human research including improved walking distance and clinical outcomes in muscle endurance and strength. Urolithin A is presented as supporting mitochondrial health by promoting mitophagy—recycling damaged mitochondria—distinct from other mitochondrial supports like CoQ10 and NAD precursors. They explain most people cannot produce enough urolithin A from foods because only 30–40% convert precursors via the microbiome and it would require about six cups of pomegranate juice daily. Dosing discussed is 500–1,000 mg/day via gummies, capsules, or powder, with effects developing over months. She reviews emerging research on immune aging, preclinical work on brain and neurodegenerative conditions, and topical urolithin A for skin.
