Melatonin is a hormone that regulates the sleep-wake cycle, often used as a supplement to improve sleep quality and manage circadian rhythm disorders.
Overview
Melatonin is a hormone naturally produced by the pineal gland in response to darkness, helping the body recognize when it’s time to sleep. It plays a central role in regulating the circadian rhythm, commonly referred to as the internal body clock.
Supplemental melatonin is widely used to treat insomnia, jet lag, and sleep disturbances caused by shift work or screen exposure. It provides a non-addictive alternative to prescription sleep aids and is generally well-tolerated when used in recommended doses.
Research
Research has consistently shown that melatonin supplementation can improve sleep onset, duration, and overall sleep quality, especially in people with disrupted natural melatonin production. It has been effective in helping individuals fall asleep faster and maintain a consistent sleep cycle.
Beyond sleep, melatonin has also shown antioxidant and anti-inflammatory properties, with studies exploring its use in immune support, neurological health, and even cancer therapy. However, more clinical trials are needed to confirm its long-term benefits in these additional areas.
