What is lactase?
Lactase is an enzyme that helps your body digest lactose found in dairy products. If you are lactose intolerant, eating dairy can lead to gas, bloating, stomach pain, or diarrhea.
Lactase is a dietary supplement that can help prevent these symptoms for people with lactose intolerance who drink milk or eat other dairy products.
It is unclear if lactase can treat any medical condition. The FDA has not approved this product for medicinal use. Lactase should not replace any medication prescribed by your doctor.
Lactase is usually sold as a dietary supplement. There are no regulated manufacturing standards for supplements, and some products on the market have been found to be contaminated with toxic metals or other drugs. It is important to buy dietary supplements from a trustworthy source to reduce the risk of contamination.
Lactase may also be used for purposes not mentioned in this product guide.
