Melatonin SAP 10 mg NEW 60 tablets -

Melatonin is a hormone (N-acetyl-5-methoxytryptamine) produced mainly at night by the pineal gland. Its secretion is stimulated by darkness and inhibited by light. Melatonin, an indole, is synthesized from tryptophan by serotonin. The suprachiasmatic nuclei (SCN) of the hypothalamus have melatonin receptors, and melatonin can act directly on the NSCs to influence the circadian (sleep) rhythm.
