Standardized Dietary Supplement. Unique, drug-free formula. For a natural sleep cycle. Sleep better to feel better. Melatonex is a dietary supplement containing melatonin, a substance produced by our own bodies that regulates the body's natural sleep/wake cycle. After we reach maturity, melatonin production declines with age which can make restful sleep more difficult to achieve. Melatonin production can also diminish through our use of substances like alcohol, tobacco, caffeine, aspirin and many common medications. Melatonex supplementation can help to restore the melatonin we need for a restful, natural sleep. Unique time-release delivery Melatonex uses a unique time-release delivery system that releases melatonin the way the body does, gradually while you sleep. Antioxidant action. Research shows melatonin to be a highly effective antioxidant against hydroxyl free radicals, toxic by-products of normal metabolism that can cause cell damage. Contains No: sugar, yeast, sodium, preservatives or artificial colors. (These statements have not been evaluated by the Food and Drug Administration.
