The Active Ingredient Is: Serrapeptase (Proteolytic Enzyme)

Serrapeptase is a proteolytic enzyme that targets protein debris in the body, contributing to normal tissue turnover and maintenance of internal protein balance. This form is derived from Serratia species and is presented in a delayed-release vegan capsule to support intestinal absorption.

What Does Serrapeptase Do?

Serrapeptase helps break down protein debris that can come from inflammation or congestion, backing the body's natural clearance processes. It also supports sinus health and immune function within the broader context of normal physiological activity.
