Fact Sheet: Melatonin. Melatonin is a hormone that helps you fall asleep. It has been taken for years as a supplement to assist with sleep; however, some doctors suggest that we are sabotaging our sleep by overusing it. Posted on 9/24/2012.
Recommended dosage, active amounts, other details. For regulating the sleep cycle, doses of melatonin between 500mcg (0.5mg) and 5mg seem to work. Start with 500mcg, and if it doesnât work, work up to 3-5mg. The benefits of melatonin are not dose-dependent - taking more will not help you fall asleep faster.
