Melatonin (MT) is a hormone secreted by the pineal gland. It belongs to the indole heterocyclic compound family and its chemical name is N-acetyl-5-methoxytryptamine. It is also known as pinealin, melatonin, and melatonin.
Currently, chemical synthesis is the primary method for obtaining melatonin. Based on its structural characteristics, the indole ring is the core component of melatonin. Its synthesis routes can be divided into two main categories based on the starting materials: ring-building synthesis and ring-borrowing synthesis. The former is synthesized from simple starting materials containing a benzene ring, while the latter is synthesized from starting materials containing an indole ring.
Melatonin is commonly found in animals and has both hydrophilic and lipophilic properties. It reacts with hydroxyl and peroxyl free radicals. In recent years, melatonin has also been discovered in plants.
Key Features
Melatonin acts on the human hypothalamus, a substance secreted by the pineal gland in the human brain. It plays a very important role in maintaining the body's normal circadian rhythm and sleep rhythm. It can also relieve insomnia, depression, and anxiety, and is a supplement to maintain brain balance.

Our packing method is 1KG/Aluminium bags, 25kg/drum
For some products that require special packaging during transportation, we will carry out more delicate packaging. For example, retinal needs to be stored at -20 °C, so we choose cold chain transportation during transportation; deoxyarbutin will change color during transportation, so we will Vacuum packing of deoxyarbutin
