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.

Cause and effect
1 study reviewed
In plain English

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 study
  1. Study: Melatonin as a Novel Drug to Improve Cardiac Function and Quality of Life in Heart Failure Patients: A Systematic Review and Meta‐Analysis

    The 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.
