Melatonin is a slightly off-white, odourless crystalline powder. It is very slightly soluble in water and in dilute hydrochloric acid.
Melatonin is a small molecule, a derivative of the amino acid tryptophan, N-acetyl-5 methoxytryptamine. It is a potent hormone with well-recognized activities and the potential to influence many bodily functions. It is produced by the pineal gland in the brain and is secreted when the body recognizes darkness. Melatonin has intense effects on the timing of the sleep/awake cycle, regulating the circadian rhythms of several biological functions. This is its most studied biological activity. Melatonin, as a multifunctional hormone, appears to regulate or modulate other functions in humans through the activation of its receptors and works as a strong antioxidant that protects the DNA.

Melatonin can delay aging and improve sleep. Melatonin is an amine substance secreted spontaneously in the human body. Its role is to relieve melanin deposition. Melatonin can play an anti-oxidant effect, affect cell renewal metabolism, and affect the content of fat and protein in cells. It plays a role in delaying aging and is of great significance to maintaining the elasticity and integrity of the skin surface.
Melatonin can act on the pituitary gland, reduce the time to wake up from sleep, reduce the time to fall asleep, help sleep, and improve the quality of sleep. Melatonin can regulate the immune system and play an important role in maintaining the body’s immunity.
The Uses of Melatonin:
1. Melatonin can be used as medicine health care products, so as to enhance people’s immune function, preventing aging and back to youth. What’s more, it is also a kind of natural “sleeping pill”.
2. Melatonin is a kind of hormone secreted by pineal body of pituitary gland in the body. The amount of melatonin has something to do with light. The weaker the light is, the more the melatonin is, whereas the less. In addition, it is helpful to one’s sleep.
3. Biochemical research.
