For those with lactose intolerance, you may be all too familiar with what we picked from our digestive enzymes, lactase. Lactase digestion helps you process the lactose in dairy, helping to prevent bloating, gas, constipation, diarrhea, and cramping that happens to many who ingest milk products. Lactose intolerance is not an allergy, it is about a missing enzyme necessary for the proper digestion of dairy. For those who can digest dairy, lactase is produced by cells in the small intestine. For those who are intolerant, it is not—or it is not produced in sufficient quantity.
