Lactase

Lactose is the sugar found in milk and dairy products. It's estimated that 68% of adults worldwide have lactose intolerance, which means that they don't produce enough lactase enzyme to break down lactose. Lactose intolerance can cause bloating, gas, and diarrhea after consuming dairy products. Lactase supplementation may improve the digestibility of lactose and help reduce the symptoms of lactose intolerance.
