Biological enzyme, that is, the enzyme promoted by some businesses, is generally called biological enzyme by regular businesses. Any metabolism will produce biological enzymes. For example, when we eat, we secrete sialidase and there is pepsin in our stomach. These are catalysts for metabolism, which are produced by other organisms. If we eat it in the stomach, the effect will be different, and it will be decomposed by gastric acid. Otherwise, the metabolic catalysts of other organisms are catalyzed in the human body, which is a mess.

Enzymes are biological enzymes, and the functions of oral enzymes have not been scientifically verified.

Better check the production license. If it is food, then promoting the health care function or the role of drugs is false propaganda.
