Product Details



Description:
Melatonin is a solid, lipophilic, hydro-phobic substance, also known as N-acetyl-5-methoxytryptamine. It is the principal hormone of the human pineal gland and can also be found at much lower concentrations in plants. Melatonin is synthesized by the pinealocytes of the pineal gland. The pathway begins with the amino acid L-tryptophan, which is metabolized to 5-hydroxy-tryptophan (5-HTP), then 5-hydroxy-tryptamine (sero-tonin) and finally to melatonin. The rate limiting step in the synthesis of melatonin is the N-acetylation of 5-hydroxy-tryptamine by the enzyme arylalkylamine N-acetyltransferase (AA-NAT).

Melatonin is the primary substance that controls entrainment in circadian rhythms, or patterns of wakefulness and sleep. The pineal is a tiny gland located deep in the brain behind the eyes, which monitors the external environment, integrating this information with the internal environment and producing melatonin to regulate the daily cycle. The pineal has nerves that connect it with the retina of the eye and the primary melatonin receptor is expressed mainly in the retina. The external stimuli of light and darkness cause the pineal to change the rhythm of the enzyme AA-NAT, which then affects melatonin levels. Through this mechanism, melatonin synthesis is stimulated by darkness and inhibited by light. The pineal gland also maintains continual homeostatic control and adjustment over factors such as body temperature, acidity-alkalinity, energy balance, tissue replacement and antioxidant defenses, in synchrony with the body's clocks.

Numerous studies suggest that melatonin can support regulation of sleep, in people of all ages. Melatonin has been used for jet lag and by night shift workers and the blind. Studies with menopausal women show melatonin offers benefits for sleep and mood and potential to support the immune response. At high doses, melatonin has significant antioxidant activity, including the capacity to inhibit metal ion-catalyzed oxidation processes, specifically the Fenton reaction. Aspirin, other NSAIDs and beta-blockers may lead to decreased melatonin levels.
