Melatonin (N-acetyl-5-methoxytryptamine, CAS 73-31-4) is a ubiquitous indoleamine hormone primarily synthesized and secreted by the pineal gland in the brain, with additional production in tissues like the retina, gut, and immune cells. Its secretion follows a distinct circadian rhythm—rising at dusk, peaking at night, and declining with age—making it the body’s key "dark signal" to synchronize sleep–wake cycles and regulate circadian rhythms. First isolated in 1958 by Aaron B. Lerner and colleagues, synthetic melatonin is widely used as a dietary supplement to treat insomnia, alleviate jet lag, and adjust circadian disruptions (e.g., delayed sleep phase or shift work disorder). Beyond its core chronobiotic role, it exhibits potent antioxidant activity, modulates immune function, and supports neuroprotection, though clinical evidence for extra-sleep benefits remains evolving. Typically available as oral tablets or capsules, melatonin is generally safe for short-term use but should be used under medical supervision, especially for chronic conditions or in vulnerable populations.
