Enzymes are themselves a protein that typically exists within your body. But you can gain even better benefits from your nutrition program by supplementing digestive enzymes that help break down the foods you have trouble digesting. In fact, many supplement companies already know this, and they add digestive enzymes to their products. If your protein supplement doesn’t add digestive enzymes, consider adding one to your regimen. Look for a digestive enzyme product that contains enzymes to breakdown protein (protease enzymes, including trypsin, pepsin, bromelain, papain); carbs (amylase, lactase) and fats (lipase), emphasizing the enzymes that help with the foods you have the most trouble digesting.
