Lactaid Fast Act is a lactase enzyme supplement designed to help people with lactose intolerance digest dairy products. Lactase is an enzyme naturally produced by the body to break down lactose, the sugar found in dairy products. However, those with lactose intolerance do not produce enough lactase, leading to symptoms such as gas, bloating, and diarrhea when consuming dairy products.

Lactaid Fast Act contains lactase enzymes to supplement the body's natural supply, helping to break down lactose and alleviate digestive discomfort. The supplement is available in caplet form or as chewable tablets and works quickly to make dairy foods easier to digest.

Use and Dosage

The Lactaid Fast Act Chewables come in tablet form, which is convenient for individuals who are always on the go. These chewable tablets are designed to be taken orally by mouth, making it easier to consume dairy products without experiencing digestive discomfort. By taking the chewable tablet before consuming dairy products, individuals with lactose intolerance can enjoy their favorite dairy products, without worrying about experiencing any uncomfortable symptoms

The tablets can be taken at the first bite of dairy food, or if necessary, two tablets can be taken at one time. If you continue to eat foods containing dairy after 30-45 minutes, another tablet can be taken.

To use Lactaid Fast Act Chewable tablets, you should take one tablet with your first bite of dairy food. If necessary, you may take two chewable tablets at one time. Enjoy your dairy as usual! These tablets contain natural lactase enzymes which help to make dairy food easy to digest for those with lactose intolerance. Consult with your doctor or healthcare provider before taking any new dietary supplements.
