The enzymes in your body perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion. An enzyme’s shape is tied to its function. Heat, disease, or harsh chemical conditions can damage enzymes and change their shape. When this happens, an enzyme doesn’t work anymore. This affects the body processes the enzyme helped support. Enzymes are produced naturally in the body. They’re mostly produced in the pancreas, stomach, and small intestine. But even your salivary glands produce digestive enzymes to start breaking down food molecules while you’re still chewing. Enzymes are essential for healthy digestion and a healthy body. They work with other chemicals in the body, such as stomach acid and bile, to help break down food into molecules for a wide range of bodily functions. Carbohydrates, for instance, are needed for energy, while protein is necessary to build and repair muscle, among other functions. But they must be converted into forms that can be absorbed and utilized by your body.
