Urolithin A is a gut microbiome-derived metabolite that supports mitochondrial health. Unfortunately, the majority of people lack certain bacteria in the gut to convert precursors into Urolithin A. These precursors are a class of polyphenols called ellagitannins and ellagic acid obtained from certain foods, such as pomegranates and walnuts. Considering most of the population lacks the proper microbiome to produce Urolithin A, direct supplementation is critical to receive these benefits. Urolithin A aids in mitophagy and supports the renewal and repair process for improved mitochondrial health.
