Melatonin
Also known as N-acetyl-5-methoxytryptamine. A hormone produced by the pineal gland. Melatonin is best known for its role in regulating sleep and circadian rhythms. Melatonin also acts as an antioxidant, and—interestingly enough—may increase the exercise-induced production of growth hormone when taken in supplemental form.
See “Melatonin Information and Side Effects” for more information.
