Anonymous 31 Aug 2009. It's suppossed to start working about 30 minutes after taking it, but for me it sometimes takes up to an hour. I recently came upon a dual release form of melatonin, where half releases in about 30 minutes, and the the other half is a slow continous release over the night.
Scientific studies on the use of supplemental melatonin for improving sleep have generally used dosages in the range of 0.3 to 5.0 mg/day. Melatonin is best taken shortly before bedtime, because it usually takes effect about 30 minutes after ingestion.
