Urolithin A is a postbiotic produced by gut bacteria from ellagitannin-rich foods like pomegranate. It stimulates mitophagy—the process of cleaning up damaged mitochondria—and has been shown to improve muscle endurance in human trials.
Not all products are equal. When comparing supplements, look for third‑party testing, purity, and clinical evidence. Mitopure® by Amazentis is the only brand used in published clinical studies; Nutriissa offers ISO‑certified purity with QR‑code test results; and Super Nutrition provides an affordable lab-tested option for budget‑conscious consumers.
Choose a supplement that fits your goals and budget, and focus on overall lifestyle: diet, exercise, and sleep work synergistically with targeted molecules like Urolithin A.
