Close
Carnosine is naturally produced by the body in the liver[2] from beta-alanine and histidine. Like carnitine, carnosine is composed of the root word carn, meaning "flesh", alluding to its prevalence in meat.[3] There are no plant-based sources of carnosine.[4] Carnosine is readily available as a synthetic nutritional supplement.
