What is Lactaid?
Lactaid is an enzyme that helps your body break down lactose found in dairy products. If you have lactose intolerance, eating dairy can lead to gas, bloating, stomach pain, or diarrhea.
Lactaid is a dietary supplement that can help prevent these symptoms for people with lactose intolerance who eat milk or other dairy products.
It is not clear if Lactaid is effective for treating any medical condition. The FDA has not approved this product for medicinal use. You should not use this medicine instead of any medication your doctor has prescribed.
Lactaid is often 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.
Lactaid may also be used for purposes not mentioned in this product guide.
