The Truth On Digestive Enzyme Supplementation: When and Why Use It? Digestive enzymes. Wondering what all these are about? There is a good chance that you have heard of digestive enzymes and supplements made from them. The health and fitness industry is abuzz with digestive enzyme supplementations. Yes, they do sound good for you. But are they really okay to be taken as supplements? Let’s find out what digestive enzymes really are, and if we do need to include them in our health habits. What are digestive enzymes? Digestive enzymes are chemicals that help turn the food that we eat into absorbable nutrients. We eat food, say a banana, but our body doesn’t absorb the banana per se. It absorbs the nutrients gleaned from the banana we ate. This is where digestive enzymes come into picture. These enzymes work to break down the banana and extract the important nutrients from it. This, in turn, is absorbed by our body through the digestive system. Digestive enzymes are produced by our pancreas, liver, stomach and salivary glands. Without digestive enzymes, we will be unable to absorb important nutrition and our body would be unable to benefit from what we eat.
