Buy Melatonin 10mg — 10-Vial Kits

Naturally occurring sleep hormone

Melatonin is a hormone the body makes on its own in the pineal gland, a tiny structure deep in the brain. The body builds it from a building block found in food, and its levels naturally rise at night and fall during the day.

How it is studied

It works through the body's internal 24-hour clock, docking onto matching sites in the brain and elsewhere that help keep that daily rhythm on time.

Research context

A well-known reference molecule in research on the body's daily rhythms, studied in laboratory and animal models of the sleep-wake cycle.

Good to know

This is a naturally occurring hormone, not a lab-designed research peptide.
