Serrapeptase (serratio-peptidase) is a protein-digesting enzyme isolated from the friendly bacterium Serratia E-15 discovered in the Japanese silkworm. Doctor’ s Best High Potency Serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the individual enzyme until it reaches the intestine for optimal absorption.

OPTIMAL ABSORPTION – Serrapeptase can be destroyed by stomach acids if not properly protected. Our product uses Serrateric, a coating that protects the enzyme from stomach acids until it reaches the intestines and therefore optimizes absorption.*
BREAKDOWN PROTEINS – Serrapeptase is classified as a proteolytic enzyme meaning it digests certain proteins. Helps dissolve hard particles made of protein that cause unwanted side effects from toxins, scar tissue and cysts*
