Melatonin 3 mg Sublingual tablets, provided by
Douglas Laboratories, contain 3 mg of purest pharmaceutical grade melatonin, in
a convenient sublingual tablet. Melatonin is a natural hormone nutrient that is
synthesized from the amino acid tryptophan by the pineal gland in the back of
the brain. Melatonin also occurs in small amounts in a variety of foods. In the
body, melatonin appears to regulate sleep/wake cycles, support normal immune
function, and protect cells from free radical damage. Most of the research on
melatonin has focused on its role in maintaining normal sleep/wake rhythms. The
perception of daylight in the eyes is a signal for the pineal gland to inhibit
melatonin synthesis and release. At night or in the dark, the body’s melatonin
production rises. The rise in plasma melatonin is thought to be responsible for
bringing on sleep. Nocturnal melatonin production is highest in children and
begins to decline from adolescence on until it is virtually absent in the
elderly. Melatonin supports normal immune function by
helping maintain the activity of circulating natural killer cells. It also has
been found to function as an antagonist for stress-induced immunosuppression.
Melatonin is considered a potent antioxidant that enters all body cells to help
prevent free radical damage. In the brain, melatonin is perhaps the most
important physiological antioxidant. Due to its lipid and water-soluble
properties, it can freely cross the blood-brain barrier. In vitro studies show
that melatonin is more effective than glutathione in scavenging toxic hydroxyl
radicals, and also more efficient than vitamin E in neutralizing peroxyl
radicals which can induce DNA damage. Furthermore, melatonin stimulates the main
antioxidant enzyme of the brain, glutathione peroxidase. Melatonin 3 mg Sublingual may be a useful dietary
supplement for individuals wishing to supplement their diet with melatonin. Adults take 1 tablet daily or as directed by
physician. Warning: Not to be taken by individuals under the age of
