What is Melatonin?
Melatonin is a hormone naturally produced by the pineal gland in response to darkness, playing a central role in regulating the body's sleep-wake cycle.
Why is it associated with your biological clock?
Exogenous melatonin aligns with the body's own pineal gland output to signal the onset of the sleep phase, helping correct the biological clock — particularly useful for those exposed to blue light or irregular schedules.
What does the research say?
General background on Melatonin's role and research status is available via the NCCIH overview of Melatonin.

Safety considerations
Melatonin is generally well tolerated at typical supplement doses. It may cause mild drowsiness the next morning in some people; taking it consistently at the same time each night is generally recommended.
