Melatonin PR 3 mg - 180 Tablets

Melatonin P.R.

Melatonin P.R. tablets from Douglas Laboratories contain 3 mg of pure pharmaceutical grade melatonin, in a prolonged-release 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.
