Lactase (ß-Galactosidase) is a digestive enzyme that breaks down the lactose of milk and dairy products into harmless simple sugars, glucose and galactose. People lacking this enzyme are unable to utilize lactose fully and that may lead to unpleasant symptoms. Lactase enzyme improves lactose digestion in individuals, who have difficulty digesting lactose.* LACTASE is an ideal supplement for those, who wish to enjoy the benefits of whey, casein, caseinate or milk proteins, but suffer from lactose intolerance. Generally 2500 FCC units are required for the digestion of 10-13 grams of lactose (typically whey protein concentrates contain 5-6% lactose). For very sensitive lactose intolerant consumers, who need a 100% conversion, 10 000 FCC units per meal are recommended. 2 of our capsules provide this quantity of enzyme!
