Melatonin is a hormone produced by the pineal gland in the brain as a response to darkness. It is primarily responsible for regulating the body’s circadian rhythm (24-hour internal clock) and managing a natural sleep cycle. Research suggests that Melatonin supplements may help with certain conditions such as insomnia, jet lag, and Delayed Sleep-Wake Phase Disorder. In addition to its benefits for sleep, this hormone has strong antioxidant properties.*
