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

An enzyme that breaks down hemicellulose, a fibrous component of plant cell walls, typically produced through fungal or bacterial fermentation and included in digestive enzyme blends.

Why it’s used

Included in enzyme blends taken to support the breakdown of plant fiber and carbohydrates during digestion.

What the evidence says

There is no NIH ODS fact sheet on hemicellulase, and human clinical evidence on oral supplementation with this enzyme for digestive symptoms is minimal.

Context
