Enzymes are the spark of life — they run your entire body. You couldn’t digest or absorb food, and thus would die without them. Enzymes are specific catalysis which join with coenzymes (vitamins and minerals) to allow use by your body.
You are what you digest. We cannot expect to be healthy if our digestive system isn’t functioning properly. Enzymes are essential to a healthy digestive system and a healthy body because they help transform undigested food into nutrients.
