The role of melatonin is to improve sleep, and the latter is low in fat and sugar to improve the intestine. In addition, melatonin also has a health food approval certificate issued by the former Ministry of Health and a health food production license issued by the Food and Drug Administration.
Extended data
Melatonin is not a prescription drug, but a dietary supplement, similar to health food. Generally speaking, there is no side effect at normal dose because its action period is very short. Even if it works, it only shortens everyone's sleep time by about a quarter of an hour. After a quarter of an hour, it will decompose in large quantities in human blood.
Melatonin is a very common dietary supplement abroad. In the United States, manufacturers are responsible for the safety of dietary supplements, but in China, it is relatively stricter than in the United States, because China adopts the approval system.
People's Daily Online-Melatonin is accused of stealing the concept of 17 or containing Melatonin.
