Frequently Asked Questions

What does SPU mean on serrapeptase labels?

SPU (Serratiopeptidase Units) measures the enzyme's proteolytic activity. A typical dose is 60,000-120,000 SPU (equivalent to 10-60mg). Some products use SU (Serrapeptase Units). Always compare enzymatic activity units, not just milligrams, when choosing products.

Why must serrapeptase be enteric-coated?

Serrapeptase is a protein enzyme that is destroyed by stomach acid. Enteric coating protects it until it reaches the alkaline environment of the small intestine, where it is absorbed intact into the bloodstream. Without enteric coating, most of the enzyme is inactivated before absorption.

How does serrapeptase compare to bromelain?

Both are proteolytic enzymes used for inflammation. Serrapeptase has stronger fibrinolytic (clot-dissolving) activity, while bromelain has broader clinical evidence and COX-modulating effects. Some practitioners combine them. Bromelain has a larger evidence base, but serrapeptase may be superior for fibrin-related conditions.
