Melatonin is a hormone produced in the brain by the pineal gland from serotonin. It is used primarily to support sleep.* It is also commonly used to reduce jet lag.* Low melatonin levels are considered a very common cause of sleeplessness.

Several double-blind studies have shown that melatonin supplementation is effective in promoting sleep when melatonin levels are low; however, if an individual takes melatonin when levels are not reduced, then it reportedly has no effect.*

Melatonin can be advantageous for those deficient in glutathione, as it encourages the production of glutathione peroxidase. It has significant antioxidant properties, as well as the power to promote phosphorylation of pyridoxine in the brain, thus enabling the formation of pyridoxal 5-phosphate. Furthermore, it assists in vitamin B-6's methylation process to allow efficient absorption and use.
