This product is an enzyme supplement used to help people who have trouble digesting milk and other dairy products (lactose intolerance). Lactose is a type of sugar found in milk products. Lactase enzyme is normally produced by the body to help break down (digest) lactose. Lactose intolerance occurs when the body produces low amounts of lactase enzyme. Lactose intolerance can begin at different ages. Infants are not usually affected, but lactose intolerance can affect children as young as 2. It is very common in adults. One way to treat lactose intolerance is to avoid milk products.
