Enjoy dairy products again with Lactaid® Extra Strength Tablets. Designed for those who are lactose intolerant, each extra strength tablet contains 4500 Food Chemical Codex Lactase Units (FCCLU). This natural-source lactase enzyme breaks down the lactose in milk into two simple sugars, making milk and other dairy products more digestible for those who have difficulty digesting lactose. Taking Lactaid® Extra Strength Tablets just before consuming dairy products can help prevent gas, diarrhea, and bloating.
