What's a good night's sleep worth to you? How about a good night's sleep night after night after night? As a sleep-promoting supplement, melatonin is often misunderstood as a relaxant or sedative. But melatonin really doesn't do that, instead, the brain uses melatonin a few different ways, all of which contribute to more regular and restorative sleep. As a hormone, melatonin helps you coach your body into falling asleep at the same time and sleeping through the night. Melatonin also has a balancing effect on other hormones. As an antioxidant, melatonin protects the brain free radical effects that contribute to brain aging. Yet melatonin is one of the least expensive and safest of all dietary supplements. People use widely varying doses of melatonin, but in general the older you are, the more you're likely to need. At higher doses of 5 mg and beyond, you'll want to use a top-quality product like this one from Natrol, which includes vitamin B-6 to support melatonin's activity. The longer you use melatonin, the better it works, and vice-versa, so be sure to use Natrol Melatonin on a regular nightly basis in order to fully benefit from it.
