New research on melatonin, a popular sleeping aid, has raised concerns among scientists about its long-term usage. A study of over 130,000 adults found that those taking melatonin for more than a year were at greater risk of heart failure and dying from any cause. While the findings are preliminary and don’t change current health recommendations, they suggest that longer-term uses of melatonin need to be studied further.
Melatonin is considered safe for short-term use among non-pregnant or breastfeeding adults, but there’s limited research on its effects after 1-2 months. The study, presented at the American Heart Association’s Scientific Sessions, highlights the need for more comprehensive research on melatonin supplements.
The researchers analyzed electronic health records from US and UK adults who took melatonin for over a year. They found that those taking melatonin were almost 3.5 times more likely to be hospitalized for heart failure and had a higher risk of dying from any cause. However, the study’s methodology has limitations, including lack of information on melatonin use.
The findings challenge the perception of melatonin as a benign chronic therapy and highlight the need for further research to clarify its safety profile. While melatonin is considered safe in short-term use, its long-term effects are still unknown.
