Sleep is an indispensable function of the human body. The pineal gland in the human brain secretes melatonin, which is a hormone that helps sleep. Due to excessive social pressure, people have problems such as poor sleep. Moreover, people secrete less and less melatonin, which leads to the phenomenon of insufficient sleep. Therefore, in order to improve sleep conditions, external supplements are usually taken to increase the body's melatonin. The melatonin soft capsule produced by Guangzhou Changshengkang Biotechnology Co., Ltd. contains 0.31g melatonin per 100g, which can help improve sleep quality.
