Melatonin is a naturally occurring hormone produced by the pineal gland in the brain that helps regulate the body’s sleep-wake cycle (circadian rhythm). It signals to the body when it’s time to sleep, especially in response to darkness.

As a supplement, melatonin is commonly used to aid with insomnia, jet lag, and shift work sleep disorders. It may also support relaxation, faster sleep onset, and better sleep quality without the risk of dependency.

Melatonin is available in tablets, capsules, gummies, and sublingual sprays, and is popular among individuals seeking natural sleep support.
