Melatonin as a medication and supplement

Supplement and medication used to treat sleep disorders

Melatonin is a dietary supplement and medication as well as naturally occurring hormone. As a hormone, melatonin is released by the pineal gland and is involved in sleep–wake cycles. As a supplement, it is often used for the attempted short-term treatment of disrupted sleep patterns, such as from jet lag or shift work, and is typically taken orally. There is evidence of its benefit for this use, however, it is not strong. A 2017 review found that sleep onset occurred six minutes faster with use, but found no change in total time asleep.
