Melatonin is a hormone that your brain produces in response to darkness. It helps with the timing of your circadian rhythms (24-hour internal clock) and with sleep. Being exposed to light at night can block melatonin production.
Research suggests that melatonin plays other important roles in the body beyond sleep.
Melatonin dietary supplements can be made from animals or microorganisms, but most often they're made synthetically. The information below is about melatonin dietary supplements.
