Cover Story: Melatonin is not only of pineal origin, but also a product of most extrapineal cells. It is present in all life domains of bacteria, archaea and eukaryotes. The total body melatonin load is a contribution from potentially every cell, microbiota of the gut, skin, mouth, nose and vagina and from the diet. During evolution, pineal melatonin became the chemical expression of darkness characterized by its circadian rhythm; a major portion of melatonin is also generated during sunlight exposure, when extrapineal cells respond to non-visible infrared light which penetrates through to most cells of the body. Thus, melatonin is produced at night and also during the day. Melatonin serves a multitude of functions including circadian regulation, antioxidant, immune enhancement and anti-inflammatory actions. View this paper
