Taking melatonin pills for heart failure patients doesn't seem to help their hearts pump blood better. Research shows that adding melatonin to their treatment doesn't make a meaningful difference in how well their hearts work compared to just taking a placebo.

Our current analysis shows that melatonin does not appear to improve heart pumping function in patients with heart failure. The evidence we have reviewed so far leans toward the idea that adding melatonin to standard treatments does not make a meaningful difference in how well the heart moves blood. We analyzed one assertion and found that zero studies support this benefit, while thirty-nine studies refute it [1]. When we look at what we have reviewed, the data points to a consistent pattern. Heart failure means the heart struggles to pump blood efficiently to the rest of the body. Some people wonder if melatonin, a hormone that helps regulate sleep, might also support heart muscle strength. Our review of the available research suggests that melatonin pills do not change how well the heart pumps compared to taking a placebo. The numbers we tracked show thirty-nine studies refute the idea that melatonin improves pumping function, and zero studies support it [1]. We want to be clear that this is our current analysis based on the evidence available right now. Our understanding will improve over time as new research is published. For now, the evidence we have reviewed leans toward melatonin not providing a measurable boost to heart pumping in heart failure patients. If you or someone you know is managing heart failure, it is important to speak with a healthcare provider before starting any new supplement. Melatonin might still help with sleep, but it should not be used as a treatment to strengthen heart pumping. Always follow the care plan your doctor recommends for your heart health.
