How is melatonin relevant to schizophrenia?

Melatonin is a hormone primarily synthesised by the pineal gland. Secretion of melatonin by the pineal gland shows a circadian rhythm synchronised to the light-dark cycle. Melatonin has been reported to be involved in various important biological functions in the body: sleep regulation, circadian rhythm, immune modulation, reproduction, anti-inflammation, antioxidant, and energy metabolism. Various studies have reported the beneficial effects of taking melatonin for improving metabolic problems; problems often observed in people on antipsychotic medications.
