The Risks of Inconsistent Melatonin Dosages in Sleep Aid Supplements

A JAMA study found that 88% of melatonin gummy products analyzed were inaccurately labeled, containing over 10% more or less melatonin than what was listed on the packaging. The dietary supplement products contained a range of melatonin that spanned 1.3 mg to 13.1 mg per serving, representing a range of 74% to 347% of what they were supposed to contain based on their labeling. The finding highlights a larger concern over the quality, safety, and effectiveness of dietary supplements, particularly for children who commonly use gummy versions of the supplement.
