It exists in many organisms, from algae to humans, and its level varies with the time of day.

Melatonin is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Very small amounts of it are found in foods such as meats, grains, fruits, and vegetables. Your body has its own internal clock that controls your natural cycle of sleeping and waking hours. In part, your body clock controls how much melatonin your body makes.
Normally, melatonin levels begin to rise in the mid- to late evening, remain high for most of the night, and then drop in the early morning hours. Light affects how much melatonin your body produces. During the shorter days of the winter months, your body may produce melatonin either earlier or later in the day than usual. This change can lead to symptoms of seasonal affective disorder (SAD), or winter depression.
Natural melatonin levels slowly drop with age. Some older adults make very small amounts of it or none at all. Can be used to treat jet lag or sleep problems (insomnia). Melatonin is a potent antioxidant that defends against free radicals and helps to support glutathione activity in the neural tissue.




1. Delaying senility:

It can shorten the time of awakening and falling asleep before sleep, improve the quality of sleep, significantly reduce the number of awakenings during sleep, shorten the period of shallow sleep, prolong the period of deep sleep, and lower the threshold of wake-up in the morning the next day. It has strong function of adjusting time difference.

Mainly used in whitening and moisturizing cosmetics, but also often used in hair products.

2. Improving sleep:

The biological function of melatonin, especially its health function as a dietary supplement, has been extensively studied at home and abroad. It shows that melatonin has many physiological functions such as promoting sleep, regulating time difference, anti-aging, regulating immunity, anti-cancer and so on.

The health function of melatonin at home and abroad involves regulating endocrine (inhibiting ovulation), protecting encephalitis virus infection, reducing the mortality rate after infection, AIDS treatment and cardiovascular protection.
