Simply speaking, this drink is to supplement lactic acid bacteria. Lactic acid bacteria is a kind of bacteria, but it can survive in the human intestine, so it is also called probiotics. This kind of bacteria can help the human digestive system digest food and produce nutrients that are beneficial to human absorption.

However, compared with everyone's diet, the number of probiotics in everyone's intestines is different, and it is easy to upset the balance of human intestines by supplementing probiotics indiscriminately.

Therefore, lactic acid bacteria are good for the stomach, but you can't drink it in large quantities, just drink it moderately.
