Melatonin is a hormone produced in the pineal gland which regulates sleep and wakefulness.[1] It is involved in the synchronization of circadian rhythms, including sleep-wake timing, blood pressure and body temperature regulation, cardiovascular efficiency and muscle strength, and many others.[2] Many of its biological effects are produced through activation of melatonin receptors,[3] while others are due to its role as an antioxidant,[4] with a particular role in the protection of nuclear and mitochondrial DNA.[5]

As a medicine, it is used for the treatment of insomnia, however, scientific evidence is insufficient to demonstrate a benefit in this area.[6]

Notable studies[edit]

Costs and availability[edit]

In Canada and the United States, melatonin is sold over-the-counter. In other countries, such as the United Kingdom, it is only available with a prescription.
