Urolithin A is not known to be found in any food. It forms as the result of transformation of ellagic acids and ellagitannins by the gut microflora in humans. Ellagic acid itself results from the hydrolysis of ellagitannins in the gut in the presence of water.

Sources of ellagitannins are: pomegranates, nuts, some berries (raspberries, strawberries, blackberries, cloudberries), tea, muscadine grapes, many tropical fruits, and oak-aged wines.

 

The conversion of the ellagic acids into urolithin A depends on individual microflora composition and can vary significantly.
