DOES IT WORK?
Results vary. Maltase (alpha-glucosidase) completes the final step of starch digestion by converting maltose into glucose. Your body naturally produces it in the brush border of the small intestine. Supplemental maltase is mainly useful for people with digestive enzyme insufficiency or as part of a comprehensive enzyme blend. Healthy people generally don't need it.

Mechanism of Action
Maltase (alpha-glucosidase) cleaves the alpha-1,4-glycosidic bond in maltose, producing two glucose molecules. This is the final enzymatic step before glucose can be absorbed across the intestinal epithelium.
