The Claim

Oral administration of 10 mg melatonin nightly for 24 weeks significantly reduces serum N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels by a mean of approximately 111 ng/L in patients with stable heart failure with reduced ejection fraction (HFrEF), indicating potential neurohormonal modulation.

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 a 10-milligram melatonin pill every night for six months can significantly lower a specific heart stress marker in people with a common type of heart failure. This drop in the marker suggests the supplement might help calm the body's stress hormones that strain the heart.

See the scientific wording

Oral melatonin supplementation at a dose of 10 mg nightly for 24 weeks significantly reduces serum N-terminal pro-B-type natriuretic peptide (NT-pro BNP) levels in patients with stable heart failure with reduced ejection fraction (HFrEF), with a mean reduction of approximately 111 ng/L compared to placebo, indicating potential neurohormonal modulation in this specific clinical population.
