What is Lactase?
Lactase, also known as β-galactosidase, is an enzyme that hydrolyzes lactose—the sugar found in milk—into its digestible components, glucose and galactose. It is naturally produced in the human small intestine, but individuals with lactose intolerance lack sufficient levels of it. Commercial lactase is derived from microbial fermentation and is used in dietary supplements, infant formulas, and industrial processing of lactose-free milk and dairy products.
