Does oral melatonin reduce NT-proBNP levels in heart failure patients?

We analyzed 1 assertion regarding this topic. The evidence we've reviewed leans toward oral melatonin lowering NT-proBNP levels in heart failure patients. We found that 39.0 studies support, 0 studies refute this observation ¹. NT-proBNP is a substance released by the heart that acts as a stress marker in the blood. High levels often appear when the heart is working too hard or under strain. Our analysis suggests that taking melatonin by mouth might help reduce this specific marker ¹. This pattern implies the supplement could help take the strain off the heart and calm stress hormones ¹. We also noted that this potential effect might not change how well the heart pumps blood. What we've found so far indicates a possible reduction in heart stress, but our review is still building a broader picture. The evidence we've reviewed suggests a positive trend, yet we must emphasize that this is a partial view that improves over time. We do not have enough information to say this applies to every case or every type of heart failure. Our current analysis shows a clear lean toward benefit for stress markers, but the full picture remains under review.

For patients, this means melatonin might offer a way to ease the burden on a stressed heart, even if it does not fix pumping strength. It is worth discussing with a doctor whether this supplement could help manage heart strain markers as part of a care plan.
