Description and Uses

Melatonin, at times referred to as the “hormone of darkness,” normally is secreted during the night. It is synthesized in the pineal gland, and its secretion is controlled by the suprachiasmatic nucleus, following an endogenous circadian rhythm. Studies indicate that melatonin may
