Serrapeptase (also called serratiopeptidase) is a highly potent protein-dispersing enzyme that has been used in Europe and Asia for more than a quarter century. Serrapeptase is prepared under highly controlled conditions from cultures of the non-pathogenic bacterium Serratia 15. Best High Potency Serrapeptase is standardized in modern enzyme activity units and formulated with Serrateric, a superior, all-natural, vegetable based alternative to enteric coating that protects the individual enzyme molecules until they can reach the intestine to be absorbed.
