Melatonin, also known chemically as N-acetyl-5-methoxytryptamine, is a naturally occurring compound found in animals, plants, and microbes.In animals, circulating levels of melatonin vary in a daily cycle, thereby regulating the circadian rhythms of several biological functions.Many biological effects of melatonin are produced through activation of melatonin receptors, while others are due to its role as a pervasive and powerful antioxidant, with a particular role in the protection of nuclear and mitochondrial DNA.

Melatonin in plants has multiple roles, including regulation of the photoperiod, in plant defence responses, and as a scavenger of reactive oxygen species.

Products containing melatonin have been available as a dietary supplement in the United States since 1993. 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.

Foods may contain trace amounts of melatonin, but no food has been found to elevate plasma melatonin levels.



Melatonin is the hormone secreted by the pineal gland. In humans, the plasma levels of melatonin are high at night and low during the day and it appears to have a role in circardian rhythm regulation. This action of melotonin finds a possible place in the management of jet lag and other sleep disorders. Melatonin is also being used in the treatment of cluster headaches.
