Serrapeptase is a proteolytic enzyme originally isolated from the bacterium Serratia marcescens, which was first discovered in the silkworm intestine.
This enzyme has been used for decades in clinical settings across Europe and Asia, primarily for its anti-inflammatory and fibrinolytic properties.
It is known for its ability to break down non-living protein tissue, such as those found in inflammation, edema, and scar tissue, without affecting living tissue.
The enzyme is a metalloprotease, meaning it requires a metal ion (typically zinc) for its catalytic activity.
Serrapeptase is unique among proteases for its high specificity and stability, particularly in the gastrointestinal tract when formulated as enteric-coated tablets.
It is widely used in dietary supplements and pharmaceuticals to support respiratory health, joint comfort, and cardiovascular health by promoting healthy blood flow and reducing inflammation.
