Features Specifications: Melatonin
Melatonin, or 5-methoxy-N-acetyltryptamine, is a naturally occurring hormone found in most animals, including humans, and some other living organisms, including algae . Circulating levels vary in a daily cycle, and melatonin plays a role in the regulation of the circadian rhythms of several biological functions. Many biological effects of melatonin are produced through activation of melatonin receptors, while others are due to its role as a pervasive and powerful anitoxidant with a particular role in the protection of nuclear and mitochondrial DNA .
The use of melatonin as a drug can entrain (synchronize) the circadian clock to environmental cycles and can have beneficial effects for treatment of certain insomnias. Its therapeutic potential may be limited by its short biological half-life, poor bioavailability, and the fact that it has numerous non-specific actions.
