Best Natto-Serra is a combination of two natural enzymes that have been used as dietary supplements for decades. Serrapeptase (serratiopeptidase) is a protein-digesting enzymen isolated from the friendly bacterium Serratia E-15 discovered in the Japanese silkworm. Nattokinase also digests protein and is derived from "natto," a fermented soy food popular in Japan for centuries. This nattokinase is free of vitamin K. The serrapeptase is formulated with Serrateric™, a superior alternative to enteric coating that protects the enzyme until it reaches the intestine for optimal absorption.
