Melatonin, the pineal hormone, is a simple derivative of tryptophan and serotonin.  Endogenous melatonin is synthesized and released in response to light and dark on the retina.  Its secretion is inhibited by bright light.  It has also been suggested that chronic exposure to electromagnetic fields may suppress melatonin production.  Melatonin also functions as an antioxidant.  It specifically scavenges the damaging hydroxyl radical.  Like other "anti-aging" hormones, melatonin is produced in abundance in early life, but declines steadily with age.*

Accumulating data supports the use of supplemental melatonin for patients with insomnia, phase-delay or other sleep disturbances, shift workers who are exposed to light at night, jet-lagged travelers and those who are occupationally exposed to electromagnetic fields. There is also evidence to suggest a link between low levels of melatonin and breast cancer.*
