where is lactase found in the digestive system
Lactase Lactase is an enzyme that some people are unable to produce in their small intestine.[5] Without it they can't break down the natural lactose in milk, leaving them with diarrhea, gas and bloating when drinking regular milk. Lactase is added to Lactose Free Milk to neutralize lactose naturally found in milk, leaving it slightly sweet but digestible by everyone.[6] Without lactase, lactose intolerant people pass the lactose undigested to the colon where bacteria break it down creating carbon dioxide and that leads to bloating and flatulence.
