Lactase is an enzyme that helps your body break down lactose in dairy products. If you are lactose-intolerant, consuming a dairy product can cause gas, bloating, stomach pain, or diarrhea.

Lactase is a dietary supplement that can help prevent these symptoms in people with lactose intolerance who consume milk or other dairy products.

It is not certain whether lactase is effective in treating any medical condition. Medicinal use of this product has not been approved by the FDA. Lactase should not be used in place of medication prescribed for you by your doctor.

Lactase is often sold as a dietary supplement. There are no regulated manufacturing standards in place for supplements and some marketed products have been found to be contaminated with toxic metals or other drugs. Dietary supplements should be purchased from a reliable source to minimize the risk of contamination.
