Roll Call does not check drug interactions or assess personal safety.

A protein-digesting enzyme produced by fermentation of Aspergillus mold species, used in enzyme supplement blends.

Why it’s used

Included in digestive enzyme products intended to support the breakdown of dietary protein, sometimes marketed for activity across a range of stomach pH levels.

What the evidence says

Aspergillopepsin is well documented as an industrial and food-processing enzyme, but clinical evidence for oral supplementation improving digestion or any other outcome in healthy people is very limited, and there is no NIH ODS coverage of this ingredient.
