In a small, recent human trial, a naturally occurring compound called urolithin A has yielded positive results and appears to slow down part of the aging process that is related to the production of energy in our cells.

What is urolithin A?

Urolithin A is the end product created when bacteria in the gut break down ellagitannins, which are polyphenols found in fruits such as pomegranates, strawberries, walnuts, and raspberries. The substance does not appear naturally in its end form, so we normally rely on the beneficial bacteria in the microbiome, our internal ecology of gut bacteria, to convert the polyphenols into urolithin A.
