The Active Ingredient Is: Serrapeptase Enzyme

Serrapeptase is basically a proteolytic enzyme that helps break down proteins as part of normal body processes. This vegan formulation uses delayed-release capsules to help absorption in the gut and is good for vegetarians and vegans. The blend also includes calcium within the capsule matrix to support its make-up.

What Does Serrapeptase Do?

Serrapeptase helps break down proteins, which can support healthy sinuses and immune function and may help with joint health. Its proteolytic activity supports normal inflammatory processes and tissue maintenance, aligning with recognised nutritional functions.
