    Melatonin (Melatonine, short for MT) is one of the hormones secreted by the pineal gland. Melatonin belongs to the indole heterocyclic compound, and its chemical name is N-acetyl-5 methoxytryptamine, also known as pineal gland, melatonin, and melatonin. After the synthesis of melatonin, it is stored in the pineal gland, and the sympathetic nerve excites the pineal gland cells to release melatonin. The secretion of melatonin has an obvious circadian rhythm, the secretion is inhibited during the day, and the secretion is active at night.


    Melatonin is an indispensable natural hormone in the human body, which controls and affects the secretion of different hormones. When melatonin is reduced in the body, various functions of the human body will be affected, and various diseases will follow. Studies have shown that the secretion of melatonin in the human body begins to decrease after middle age, and by old age, its secretion has been slightly abnormal. Early intake and supplement of sufficient melatonin can improve the function of the endocrine system, improve immunity, improve anti-tension and antioxidant functions, improve sleep, slow down the aging rate of the human body, and slow down the degeneration rate of sexual organs; Melatonin can also help prevent and treat cancer, especially for chronic insomnia.
