The Claim
Oral melatonin supplementation significantly reduces circulating N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in patients with heart failure with reduced ejection fraction, indicating a potential reduction in cardiac wall stress and neurohormonal activation without altering ejection fraction.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking melatonin by mouth might lower a specific stress marker in the blood for people with a common type of heart failure. This suggests the supplement could help take the strain off the heart and calm stress hormones, even if it doesn't change how well the heart pumps.
See the scientific wording
Oral melatonin supplementation significantly reduces circulating levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with heart failure with reduced ejection fraction, indicating a potential reduction in cardiac wall stress and neurohormonal activation. This biomarker improvement suggests melatonin may exert beneficial physiological effects on cardiac strain, even without measurable changes in ejection fraction.
What the research says
1 studyThe study found that taking melatonin lowers a specific heart stress marker in heart failure patients, even though it did not significantly change their overall heart pumping ability. This suggests melatonin helps reduce strain on the heart without necessarily improving its pumping strength.
