Doctor’s Best Natto-Serra is a combination of two natural enzymes that have been used as dietary supplements for decades. Serrapeptase (serratio-peptidase) is a protein-digesting enzyme 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.

Brand IP Statement(s) re: (c), (TM), (SM)

The Serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the enzyme until it reaches the intestine for optimal absorption.
