Ingredient overview
What it is
Melatonin is produced naturally by the pineal gland, primarily in response to darkness. It acts as a biological timing signal that helps coordinate the body's circadian rhythm.
- Scientific identity: Melatonin; molecule: N-acetyl-5-methoxytryptamine.
- How it works: Made from tryptophan: The pineal gland converts tryptophan, via serotonin, into melatonin. Released on a light-governed schedule: Levels begin climbing about two hours before habitual sleep onset, and light suppresses release.
- Primary function: Supplemental melatonin supports sleep-related routines by working with the body's normal sleep-wake signalling.
- What it supports: Melatonin helps signal that biological night has arrived, supporting a smoother transition toward sleep when timing and dose are appropriate.
- Important consideration: Appropriate timing, dose and a consistent evening routine influence its intended use.
