They identified 30 different melatonin gummy products to be sold in the US in 2021 using the National Institutes of Health’s Dietary Supplement Label Database, the most comprehensive database of dietary supplements sold in the US. Only 25 were available for purchase when the study was conducted in September 2022 and mentioned melatonin on the label.
