Long-Term Melatonin Use Linked to Increased Heart Failure Risk

November 3, 2025 - 09:01

Recent research indicates that adults who have been taking melatonin supplements for over a year may face a heightened risk of heart failure. However, experts clarify that this association does not imply that the supplement itself is the direct cause of the heart problems.

The study suggests that individuals who rely on melatonin for prolonged periods might already have underlying health issues that contribute to heart failure. This finding emphasizes the importance of evaluating the overall health status of individuals who use melatonin, particularly for extended durations.

Healthcare professionals are encouraged to monitor patients using melatonin supplements long-term, ensuring they are aware of potential risks and underlying conditions that may not be immediately apparent. As the popularity of melatonin continues to rise, this research serves as a critical reminder for users to consult with healthcare providers regarding their supplement use and to consider regular health check-ups.
