JJ Virgin interviews Dr. Anurag Singh (MD/PhD, CMO at Timeline) about mitochondrial health and the compound Urolithin A (Mitopure). They discuss the role of mitochondria in muscle, aging, immunity and skin; the risk of muscle loss with aging and during rapid weight loss (including with GLP‑1 agonists); clinical trial results showing functional gains (VO2 and strength) with Urolithin A; testing approaches for mitochondrial health (VO2max, biopsies, blood-based mitochondrial readouts); and practical recommendations (protein intake, resistance training, creatine, and Mitopure supplementation).

About 1–3% of muscle mass and strength per year after the 30s–40s.

About 15% total body weight loss in trials, with roughly 5% (or more in some trials) from muscle mass.

~500 mg/day shows strength/endurance benefits after 2–4 months; ~1,000 mg/day (1 g) used to observe larger anti‑inflammatory and immune effects.

VO2 improvements ~5–10%; strength/functional improvements ~10–12% in tests like 6‑minute walk, isokinetic leg testing, and grip strength.
