All reportsResearch overview
Melatonin (N-acetyl-5-methoxytryptamine) is an indoleamine made from serotonin in the pineal gland, mainly at night. It signals the time of day to the body through the MT1 and MT2 receptors and is the central hormone in circadian rhythm research.
Beyond its receptor actions, melatonin is a direct scavenger of free radicals and is studied as an antioxidant in cell and animal models. It is supplied as a high-purity reference material for biochemical and circadian research. Melatonin is sensitive to light, so store it in a closed, dark container, and note its limited solubility in water when preparing stock solutions.
