Melatonin
Melatonin, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring hormone found in animals and in some other living organisms, including algae. Circulating levels vary in a daily cycle, and melatonin is important in the regulation of the circadian rhythms of several biological functions. Many biological effects of melatonin are produced through activation of melatonin receptors,[4] while others are due to its role as a pervasive and powerful antioxidant[5] with a particular role in the protection of nuclear and mitochondrial DNA.
Products containing melatonin have been available as a dietary supplement in the United States since 1993. Foods may contain trace amounts of melatonin, but no food has been found to elevate plasma melatonin levels.[8] Over-the-counter sales of the hormone remain illegal in many other countries, and the U.S. Postal Service lists melatonin among items prohibited by Germany.
