Most melatonin gummy supplements sold in the U.S. are inaccurately labeled, often containing higher quantities of the sleep-promoting hormone per serving than declared on the packaging, a new study finds.
The findings, published April 25 in the journal JAMA, mean that people who take the gummies are consuming uncertain amounts of melatonin, the researchers said. The results have particular implications for children, who may accidentally ingest the products, or who may be given them by parents who hope it will help them sleep, without understanding the potential risks.
