    Product Detail 

    Melatonin (Melatonine, short for MT) is one of the hormones secreted by the pineal gland.

    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.


    The importance of peptides

    Many active substances in the human body are in the form of peptides.

    Peptides are important substances involved in various cell functions in human body. Peptides can be synthesized into cells and regulate their functional activities. Peptides act as neurotransmitters in the body, transmitting information. Peptides can be used as transportation tools in the human body to transport various nutrients and various vitamins, biotin, calcium and trace elements beneficial to the human body to the cells, organs and tissues of the human body. Peptide is an important physiological regulator of the human body, which can comprehensively regulate the physiological function of the human body, enhance and exert the physiological activity of the human body, and it has important biological functions.
