Melatonin is a hormone. Your brain makes it in the dark, in amounts so small they’re measured in picograms. It tells your body the sun went down. That’s the job. It’s a clock, and the dose your body needs for that clock is far below anything sitting on the shelf at CVS.
Then somebody decided to sell it as candy for children, and the rest of the developed world watched that happen with their mouths open.
A new study of more than 130,000 adults with chronic insomnia found that people with documented melatonin use for at least a year had about a 90% higher rate of heart failure over the next five years.
That does not prove melatonin caused heart failure. This was an observational study, and the findings were presented as a preliminary research abstract, not a peer-reviewed paper.
But the finding deserves your attention.
