Synopsis

Source of validity: Scientific
Rating (out of 5): 5

Lactase is an enzyme that breaks down lactose, the sugar found in milk and dairy products. Lactose intolerance arises from a deficiency of this enzyme in the small intestine, leading to symptoms such as bloating, gas, diarrhea, and abdominal pain when dairy is consumed. The use of lactase supplements for managing lactose intolerance is strongly supported by scientific evidence.

Multiple clinical studies have demonstrated that oral lactase supplements significantly reduce or eliminate symptoms in lactose-intolerant individuals when taken immediately before consuming dairy. The enzyme works by pre-digesting lactose, converting it into glucose and galactose—two sugars that can be absorbed without discomfort. Randomized controlled trials have shown that lactase supplementation is both safe and highly effective, especially when compared to placebo.

Lactase is available in various forms, including chewable tablets, capsules, and liquid drops that can be added directly to dairy products. Health authorities such as the National Institutes of Health and the American Gastroenterological Association recognize lactase supplementation as a valid approach for managing lactose intolerance. Unlike many digestive supplements, the efficacy of lactase is not based on tradition or anecdote; rather, it is underpinned by a clear understanding of the underlying biochemistry and robust clinical data. In summary, lactase supplementation is a scientifically validated, effective, and widely accepted strategy for supporting individuals with lactose intolerance.
