Lactase is an enzyme that catalyzes the hydrolysis of lactose, a sugar found in milk, into its constituent monosaccharides, glucose and galactose. The use of lactase to support the small intestine is strongly supported by scientific evidence, particularly in individuals with lactose intolerance. Lactose intolerance arises from a deficiency in endogenous lactase production by the enterocytes lining the small intestine, leading to malabsorption of lactose. This undigested lactose then passes into the colon, resulting in symptoms such as bloating, diarrhea, and abdominal pain due to bacterial fermentation.

Supplementing with exogenous lactase (as a pill or liquid added to dairy products) enables individuals with lactose intolerance to digest lactose more efficiently within the small intestine, thus preventing the associated gastrointestinal symptoms. Multiple randomized, placebo-controlled studies have demonstrated that lactase supplementation significantly reduces symptoms in lactose-intolerant individuals when they consume dairy products. The mechanism is well understood and is directly linked to the enzyme's capacity to compensate for the small intestine's reduced lactase activity.

Therefore, the use of lactase as a dietary supplement or food additive is justified by robust scientific research, specifically for the purpose of supporting small intestine digestive function in those with lactase deficiency. It is not a traditional remedy, but rather a scientifically validated solution developed in response to a well-characterized physiological deficiency.
