Heart Health and Long-Term Melatonin Use
Recent research indicates that individuals with insomnia who take melatonin supplements for over a year face a greater risk of heart failure compared to those who do not use this common sleep aid.
Study Findings
The study found that long-term melatonin users are more likely to be diagnosed with heart failure, require hospitalization for it, or die from any cause. These findings were presented at the American Heart Association’s Scientific Sessions 2025 in New Orleans.
It is important to note that the study is preliminary and has not yet been published in a peer-reviewed journal.
Research Limitations and Concerns
The researchers emphasized that their findings do not prove a direct cause-and-effect link between melatonin use and heart failure.
However, the results highlight potential safety issues regarding extended melatonin use, suggesting the need for further research to evaluate cardiovascular risks associated with these supplements.
Regulatory and Usage Considerations
- Many melatonin supplements are available over-the-counter without prescription.
- These products are not regulated, allowing individuals to use them without healthcare professional supervision.
“Melatonin supplements may not be as harmless as commonly assumed.”
Author’s Summary
Prolonged melatonin use may carry unforeseen heart risks, making professional guidance and further study essential for those relying on this popular supplement long-term.
