What Is It?

Melatonin is a hormone produced by the pineal gland, the organ that regulates the body’s wake/sleep/wake cycle. The hormone is activated by darkness and depressed by light.*

Uses For Melatonin Promotes Natural Sleep Cycles:

Melatonin nutritionally augments the functioning of the pineal gland, supporting the body’s natural sleep cycle. In one study, melatonin supported sleep onset when taken in the evening and did not cause morning drowsiness. A double blind, placebo-controlled, parallel design study suggested that melatonin supplementation enhanced sleep onset and sleep quality in subjects. One double blind placebo-controlled study involving an international flight crew suggested that melatonin supported healthy sleep and recovery patterns in these individuals.*
