What is Urolithin B?
Urolithin B, derived from pomegranate peels, is a phenolic compound found in the human gut after absorption of ellagitannins-containing foods such as pomegranate extract, strawberries, walnuts, or oak-aged red wine.

Urolithin B VS Urolithin A
Both Urolithin B and Urolithin A powder are used in supplements, but with different functional benefits.
Urolithin A is a much more well-researched compound, it has been generally regarded as safe (GRAS) by the FDA, while urolithin B is not. There are more supplement brands using urolithin A than urolithin B.
Urolithin A and Urolithin B are closed related. Pomegranate extract contains both of these urolithins. Pomegranates are the zenith of fruit. After digestion, their constituent parts can be converted by gut flora into urolithin C and then further transformed into Urolithin D and A, and then Urolithin B. In this sense, urolithin A can be converted to urolithin B.
Consequently, small amounts of urolithin B can be found in the blood of individuals fed with pomegranate extract;

Food sources of Urolithin B
Urolithin B is the metabolite of ellagic acid or ellagitannins (punicalagins). Pomegranates are packed full of ellagic acid, which is one form of a class called tannins. Urolithin b can be found in many fruits and nuts including pomegranate peels and seeds, some berries like raspberries or strawberries as well as grapes from muscadines to oak-aged wines, although the urolithin b content in ellagic acid is low. Urolithin B is also a natural bioactive present in shilajit extract, also known as asphaltum.
