Xylanase is a digestive enzyme that breaks down xylan, a fiber component found in plant cell walls. It is produced industrially, usually from fungal or bacterial fermentation, and added to some supplements to aid digestion of plant fibers.
Why it’s used
Included in some digestive-enzyme blends with the aim of helping break down fibrous plant material during digestion.
What the evidence says
Xylanase has a long history of use in food and animal feed processing, but direct clinical evidence for oral xylanase supplementation improving human digestion or symptoms is very limited. There is no NIH ODS fact sheet covering this enzyme, and available research is largely industrial or animal-feed focused rather than clinical.

This says what this database holds under these terms. It is not a finding that no research exists.
Context
Human trial data on specific oral dosing of xylanase for digestive symptoms is sparse, so no established dosing pattern has emerged from clinical research.
