Lactase is a β-galactosidase enzyme primarily found in the small intestine, responsible for breaking down the milk sugar lactose. It catalyzes the hydrolysis of lactose into its simpler monosaccharide components, glucose and galactose, enabling their absorption.
Reported Benefits (Provisional)
Origin & History
Lactase (EC 3.2.1.108), also known as β-galactosidase, is a digestive enzyme produced in the brush border of the small intestine. It catalyzes the hydrolysis of lactose, a disaccharide sugar found in dairy products, into its constituent monosaccharides, glucose and galactose. This enzymatic action is crucial for the proper digestion and absorption of dairy, particularly for individuals with lactose intolerance.
Research Narrative (Provisional)
Extensive clinical trials and meta-analyses consistently confirm lactase's efficacy in reducing gastrointestinal symptoms associated with lactose intolerance. Research supports lactase enzyme supplementation as a safe and effective method for improving lactose digestion and enhancing the absorption of dairy-derived nutrients like calcium.

Nutritional Profile
- Lactase (EC 3.2.1.108): The enzyme responsible for breaking down lactose. - Lactose: The disaccharide substrate, a sugar found in milk and dairy products. - Glucose and Galactose: The monosaccharide products of lactose hydrolysis, readily absorbed for energy and metabolic processes.
Reported Mechanism (Provisional)
Lactase, a β-galactosidase enzyme (EC 3.2.1.108), is produced by enterocytes lining the brush border of the small intestine. It catalyzes the hydrolysis of the β-glycosidic bond in lactose, splitting it into glucose and galactose. This occurs via a double displacement reaction involving a glutamate nucleophile and Mg-dependent acid catalysis.
Clinical Narrative (Provisional)
Extensive clinical trials and meta-analyses consistently confirm lactase's efficacy in reducing gastrointestinal symptoms associated with lactose intolerance. Research supports lactase enzyme supplementation as a safe and effective method for improving lactose digestion and enhancing the absorption of nutrients like calcium and vitamin D from dairy products. These studies typically involve individuals with diagnosed lactose intolerance, demonstrating significant reduction in bloating, gas, and diarrhea upon supplementation, thereby improving their quality of life.
