Enzymes can be preserved for a long time without opening. However, if some enzymes have exceeded the shelf life, it is best not to use them, because if they have expired, there are actually very large bacteria in the enzymes, which will do some harm to the body. Moreover, after the active enzyme is placed for such a long time, the nutrients in it will be greatly reduced and the effect will be greatly reduced. So if it expires, it is still not recommended.

Action of enzyme

Enzymes keep the body in balance: Enzymes can help keep all aspects of the body in balance. Because enzymes can make the blood in the body weakly alkaline, thus helping to remove the residual and accumulated wastes in the body, maintaining the balance of intestinal bacteria, strengthening cells, enhancing the body's resistance and so on, thus maintaining the balance of the internal environment in the body.

Enzymes help to lose weight: Enzymes help to lose weight. Obese people have too few lipases to break down excess fat in their bodies normally. The accumulated fat will make people's liver, kidneys and blood vessels heavier and induce diseases. Enzymes can supplement the lipase needed by the body, help burn excess fat effectively, and thus achieve the goal of healthy weight loss.
