Melatonin triggers sleep -- so it can help you fall asleep sooner, although it will not necessarily help you sleep longer. Generally speaking, melatonin should be taken a half-hour to an hour before bedtime to help you fall asleep (a liquid may work a bit faster than a pill). Although a range of doses have been used in successful clinical trials, keep in mind that melatonin is a hormone -- it may be wise to first see if a low dose works for you.

For a broader look at supplements for sleep, as well as prescription drugs for sleep, see the Insomnia
article in the Natural Products Encyclopedia on ConsumerLab.com. Also see our product review of Valerian Supplements
-- which may have a calming effect; our information about L-tryptophan
-- which can increase sleepiness and is used by the body to produce melatonin; and a question we answered about L-theanine
, which may, interestingly, enhance the sleep quality and improve alertness during the day.
