Many people rely on melatonin gummies to help them get a good night's sleep. But a recent study finds that these over-the-counter supplements may not reliably contain the advertised amount of melatonin.
According to the National Institutes of Health, about 19% of adults in the U.S. don't get enough sleep, and some of those sleep-deprived people use melatonin supplements to help them catch some z's.
Dr. Erik St. Louis, a Mayo Clinic neurologist, says melatonin gummies and supplements can be effective for people with sleep issues.
