Chloe needs to take an enzyme, called lactase, when she eats something with lactose in it. She asks whether the food she is eating has milk in it to see if she needs to take lactase to help her digest it. But she's not alone! Other people have lactose intolerance, too. And there are also other types of enzyme supplements that people take sometimes, too, if they have exocrine pancreatic insufficiency (EPI).
