Functions and Applications

Melatonin can inhibit the hypothalamus-pituitary-gonadal axis, reduce the levels of gonadotropin-releasing hormone, gonadotropin, luteinizing hormone and follicular estrogen, and can directly act on the gonads, reducing androgens, estrogens and estrogens. Progesterone content. In addition, MT has strong neuroendocrine immunomodulatory activity and free radical scavenging antioxidant capacity, which may become a new method and approach for antiviral therapy. MT is ultimately metabolized in the liver, and damage to hepatocytes can affect the level of MT in the body.
