Enzymes are biological enzymes. Many kinds of biological enzymes can be synthesized in our body, and these biological enzymes have the function of enzymes when synthesized in our body. But the protein we eat in our stomachs will be absorbed by amino acids, and there will be no enzyme activity.

What's more, enzymes catalyze a certain function in plants or animals. People and animals have different structures, even if they are not inactivated by gastric acid, they can't play a role.

In addition, the enzyme itself is a kind of protein. Eating too much will produce deamination reaction, produce toxins and increase the burden on the internal organs of the body.

Many unknown substances are added to the so-called enzyme slimming products, which may damage liver and kidney and affect health.
