What is Lactose Intolerance?
Lactose intolerance refers to the inability to digest significant amounts of lactose, which is the main sugar found in milk.
In order to be digested, lactose must first be broken down into two smaller sugars. This is accomplished by the enzyme lactase that is produced by the cells that line your small intestine.1-3
Lactase breaks lactose down into smaller sugars that can be easily absorbed into the bloodstream.4 If you are lactose intolerant, your body does not produce enough lactase to break down all the lactose in the foods that you eat and the beverages that you drink.1
