Melatonin is a hormone that the body naturally makes in the pineal gland. It belongs to a group of substances called chronobiotics, which help regulate the sleep-wake cycle. In the United Kingdom, melatonin is available as an active ingredient in several medicines that are marketed to support normal sleep patterns.
