Urolithins are secondary metabolites of ellagic acid derived from ellagitannins.
In humans ellagitannins are converted by the gut microflora into ellagic acid which is further transformed into urolithins A, urolithin B, urolithin C and urolithin D in the large intestines.

The urolithin precursors, ellagic acid and ellagitannins, naturally occur in some food sources such as pomegranates, guavas, tea, pecans, nuts, and berries such as strawberries, black raspberries and blackberries.  Urolithins are found in the plasma as glucuronide and sulfate conjugates at low concentrations    Urolithin A (UA) is the most prevalent metabolite of ellagitannins. However, urolithin A is not known to occur naturally in any dietary sources.

Urolithin B (UB) is an abundant metabolite produced in the gut through transformation of ellagitannins. Urolithin B is the last product after all the other urolithin derivatives are catabolized. Urolithin B is found in urine as urolithin B glucuronide.
