Mitopure Powder activates mitophagy to clear damaged mitochondria and strengthen muscles
A berry-flavored powder with 500mg of Urolithin A per sachet—the postbiotic compound shown in RCTs to boost muscle strength by up to 12% over 16 weeks and increase mitochondrial renewal by 39%. Mix into yogurt or smoothies daily. Vegan, gluten-free, no artificial ingredients. Timeline backs it with gold-standard clinical trials and a 30-day money-back guarantee.
A Phase 2b RCT (MITOPHAGY trial, ~600 participants) showed urolithin A improved muscle strength and endurance in older adults, with results published in 2023. However, the effect sizes were modest, and independent replication is limited. Mechanistic studies in cells and animals are robust, but human outcome data remain sparse beyond this single trial.
Mechanism
Urolithin A is a metabolite produced by gut bacteria from ellagic acid (found in pomegranates, berries, and walnuts). It activates mitophagy—the selective autophagy of damaged mitochondria—via SIRT3 and PINK1 pathways, potentially improving mitochondrial function and cellular energy metabolism.
“Urolithin A (UA) is a natural compound produced by gut bacteria from ingested ellagitannins (ETs) and ellagic acid (EA), complex polyphenols abundant in foods such as pomegranate, berries, and nuts.”

Caveats
Most people cannot produce urolithin A efficiently from dietary sources; the supplement bypasses this bottleneck but also means the dose and bioavailability differ from food-derived exposure. The MITOPHAGY trial was industry-sponsored (Amazentis, now part of Nestlé Health Science). Long-term safety and durability of benefit are unknown. No meta-analyses exist yet, and cardiovascular or lifespan outcomes have not been tested in humans.
