The Study
Trends in Use of Melatonin Supplements Among US Adults, 1999-2018.
This study is like taking a yearly snapshot of how many people say they take melatonin. It can tell us if more or fewer people are using it over the years, but it cannot prove that melatonin actually helps with sleep or causes any health effects. It only measures what people report, not what happens in their bodies.
