      Product Detail  


    Description

    This product is a melatonin (English name: Melatonin, chemical name: N-acetyl-5-methoxytryptamine) product with CAS No. 73-31-4. It is a hormone naturally secreted by the pineal gland in the human brain, responsible for sending the signal "it is time to rest" to the body, hence also known as the "sleep hormone". The molecular formula of the product is C₁₃H₁₆N₂O₂, with a molecular weight of approximately 232.28. It normally appears as white to off-white crystalline powder, and its purity can reach over 98% (tested by HPLC). Raw materials for health food usually require higher purity (e.g., no less than 99.5%). As a mature commercial raw material, this product can be produced by chemical synthesis or biological fermentation. Different grades including food grade, pharmaceutical grade and cosmetic grade can be supplied according to applications. It is widely used in health supplements, pharmaceuticals, cosmetics and other fields, and is a common variety with large market demand both domestically and internationally. The product shall be stored in a sealed, light-proof place with cool and dry conditions.

    Key Benefits

    Melatonin’s core function in the human body is to regulate the "biological clock", namely the body’s circadian rhythm. As night falls and light fades, the human body naturally secretes melatonin to help relax and fall asleep; when light is sufficient, its secretion decreases and the body stays awake. Therefore, melatonin supplementation helps adjust sleep rhythms, ease difficulty falling asleep, and relieve the "jet lag" caused by cross-timezone travel. In addition, melatonin has certain antioxidant and immune-regulating effects. It helps cells resist oxidative damage and maintain stable bodily conditions, making it a multi-functional ingredient that integrates sleep regulation and health maintenance.

    Its specific functions can be summarized as follows:
    Regulate sleep rhythm: Help the body establish a regular sleep-wake cycle and improve difficulty falling asleep;
    Improve sleep quality: Help extend effective sleep duration, reduce the number of nighttime awakenings and deepen sleep;
    Alleviate jet lag: Help the body quickly adapt to schedule changes across time zones and reduce discomfort caused by jet lag;
    Antioxidant effect: Help clear harmful free radicals in the body and protect cells from oxidative damage;
    Immune regulation support: Play a certain auxiliary role in regulating the body’s immune function;
    Good formulation compatibility: It has stable properties and a neutral odor, and can be flexibly used in various dosage forms such as tablets, capsules, gummies and beverages.

    Applications

    This product is a cross-industry general functional raw material. Its application scope covers many fields including health food, pharmaceuticals and cosmetics. It enjoys large and stable market demand and is a common category in export trade.
