Lactase

Digestive Enzyme

Lactase supplements hydrolyze dietary lactose in the gut. Effect depends on enzyme activity, timing relative to lactose, meal composition, product stability, and the cause of lactose malabsorption. It is not a systemic serum-tracked drug.

Pharmacokinetic model

A route-level PK model for lactase is being prepared from published data. Dosing references, studies, and documented interactions are below; the app catalog is updated as models are validated.

  1. Lactose intolerance: An update on its pathogenesis, diagnosis, and treatment Catanzaro R, Sciuto M, Marotta F · Nutrition Research, 2021 DOI

    This review describes lactose malabsorption, diagnostic limitations, diet, and lactase replacement. It provides clinical context but is not primary evidence for a particular product or activity dose.

  2. Effect of lactase on symptoms and hydrogen breath levels in lactose intolerance: A crossover placebo-controlled study Baijal R, Tandon RK · JGH Open, 2021 DOI

    In a randomized double-blind crossover study of 47 adults with breath-test-confirmed lactose intolerance, a lactase tablet reduced symptoms and cumulative breath hydrogen versus placebo. The result supports local…
