What is melatonin? Will melatonin supplements help you sleep? In this report, ConsumerLab.com explains what melatonin is, when melatonin is most likely to help with sleep problems, how to use melatonin, and shows you which melatonin supplements are high quality and best priced.
We found significant differences among melatonin supplements: Unit strengths ranged from 1 mg to 10 mg; suggested daily dosage ranged from 1 mg to 50 mg; and cost ranged from just 4 cents to $1.36 for an equivalent dose of melatonin. This means you may not be using the right dose if you go by the label, and you could be paying 33 times more than you need to if you're not using our cost comparisons.
Our review and tests of popular melatonin supplements found that one supplement failed to properly disclose its ingredients. Otherwise, the melatonin supplements (including tablets, caplets, lozenges, and liquids) contained their labeled amounts of melatonin without unacceptable lead contamination, and, if regular tablets or caplets, broke apart properly in disintegration testing.
