Heart Health: Long-Term Melatonin Use Linked to Cardiovascular Risk
New research indicates that individuals with insomnia who take melatonin supplements for over a year face a higher risk of heart failure compared to those who do not use this common sleep aid.
Study Findings
The researchers found that long-term melatonin users were more likely to be diagnosed with heart failure, require hospitalization due to this condition, or die from any cause.
“Melatonin supplements may not be as harmless as commonly assumed.”
Research Presentation and Limitations
The study was presented at the American Heart Association’s Scientific Sessions 2025 in New Orleans, but it has not yet undergone peer review. The researchers emphasize that their findings do not prove a direct cause-and-effect relationship between melatonin supplements and heart failure risk.
Concerns and Recommendations
- The results raise safety concerns regarding the prolonged use of melatonin.
- Further research is needed to evaluate the cardiovascular safety of these supplements.
- Many melatonin products are available over-the-counter without prescriptions or medical supervision.
- These supplements are not regulated, allowing use without healthcare guidance.
The study highlights potential risks linked to melatonin, suggesting caution in its long-term use.
