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]

Costs and availability[edit | edit source]

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 but may be legal to import for personal use.

mitochondria - Important parts of the biological cell, with each mitochondrion encased within a mitochondrial membrane. Mitochondria are best known for their role in energy production, earning them the nickname "the powerhouse of the cell". Mitochondria also participate in the detection of threats and the response to these threats. One of the responses to threats orchestrated by mitochondria is apoptosis, a cell suicide program used by cells when the threat can not be eliminated.

central nervous system (CNS) - One of the two parts of the human nervous system, the other part being the peripheral nervous system. The central nervous system consists of the brain and spinal cord, while the peripheral nervous system consists of nerves that travel from the central nervous system into the various organs and tissues of the body.

chronic fatigue syndrome (CFS) - A fatigue-based illness. The term CFS was invented invented by the U.S. Centers for Disease Control as an replacement for myalgic encephalomyelitis (ME). Some view CFS as a neurological disease, others use the term for any unexplained long-term fatigue. Sometimes used as a the term as a synonym of myalgic encephalomyelitis, despite the different diagnostic criteria.
