What is melatonin?
Melatonin is a hormone produced in the brain that helps regulate your sleep and wake cycle.
Melatonin is most commonly used to treat insomnia, jet lag, and to aid in giving up smoking or long-term use of anti-anxiety medicine (Valium). Melatonin is also used to help regulate sleep/wake cycles in people who are blind.
Melatonin has also been used in alternative medicine as an aid to treat insomnia caused by Alzheimer's disease or depression.
Not all uses for melatonin have been approved by the FDA. Melatonin should not be used in place of medication prescribed for you by your doctor.
Melatonin is often sold as a dietary supplement. There are no regulated manufacturing standards in place for many herbal compounds and some marketed supplements have been found to be contaminated with toxic metals or other drugs. Herbal/health supplements should be purchased from a reliable source to minimize the risk of contamination.
Melatonin may also have uses other than those listed in this product guide.
