The Claim

A 24-week daily supplementation regimen of 10 mg melatonin does not significantly reduce high-sensitivity C-reactive protein levels or improve sleep quality, anxiety, and depression scores in patients with stable heart failure with reduced ejection fraction, indicating limited anti-inflammatory and psychological benefits in this clinical population.

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 day for six months does not appear to lower inflammation or help with sleep, anxiety, and depression in people with a specific type of heart failure. This suggests that melatonin is not very helpful for these particular symptoms in this patient group.

See the scientific wording

Daily 10 mg melatonin supplementation for 24 weeks does not significantly reduce high-sensitivity C-reactive protein (hs-CRP) levels or improve sleep quality, anxiety, and depression scores in patients with stable heart failure with reduced ejection fraction, indicating limited anti-inflammatory and psychological benefits in this specific clinical population.

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

    The study gave heart failure patients 10 mg of melatonin daily for six months and found it helped their heart function and overall quality of life, but it did not lower inflammation markers or improve sleep and mood, exactly as the claim states.
