The Claim

A 24-week regimen of 10 mg nightly melatonin supplementation significantly improves composite clinical outcomes in patients with stable heart failure with reduced ejection fraction, primarily by reducing heart failure exacerbations and improving quality of life rather than altering mortality rates.

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.

Cause and effect
1 study reviewed
In plain English

Taking 10 mg of melatonin every night for six months can help people with a specific type of heart condition feel better and have fewer heart failure flare-ups. This improvement comes from better daily well-being and fewer hospital visits, rather than from preventing death.

See the scientific wording

Twenty-four weeks of 10 mg nightly melatonin supplementation significantly improves a composite clinical outcome score in stable heart failure with reduced ejection fraction patients, driven primarily by reductions in heart failure exacerbations and quality of life improvements rather than mortality changes, reflecting broader clinical benefits beyond biomarker modulation.

What the research says

  1. Study: Melatonin supplementation improves N‐terminal pro‐B‐type natriuretic peptide levels and quality of life in patients with heart failure with reduced ejection fraction: Results from MeHR trial, a randomized clinical trial

    Taking 10 mg of melatonin nightly for six months helped heart failure patients feel better, improved their daily quality of life, and lowered a key stress hormone in their blood.
