The Claim

Melatonin administration attenuates atherosclerotic plaque progression and improves plaque stability through the suppression of macrophage infiltration, inhibition of the TLR4/NF-κB inflammatory pathway, and upregulation of hepatocyte growth factor and prolyl-4-hydroxylase α1, ultimately reducing oxidative stress, necrotic core formation, and the risk of plaque rupture and thrombosis.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Taking melatonin may help keep artery-clogging plaque from growing and make it less likely to burst. It works by calming inflammation and stress in the blood vessels while strengthening the protective outer layer of the plaque, which lowers the chance of a heart attack or stroke.

See the scientific wording

Melatonin administration slows atherosclerotic plaque progression and enhances plaque stability by suppressing macrophage infiltration, inhibiting the TLR4/NF-κB inflammatory pathway, and upregulating hepatocyte growth factor and prolyl-4-hydroxylase α1. These actions reduce oxidative stress, decrease necrotic core formation, and increase collagen deposition in the fibrous cap, thereby lowering the risk of plaque rupture and thrombosis.

What the research says

1 study
  1. Study: Evidence for the Benefits of Melatonin in Cardiovascular Disease

    The study confirms that melatonin protects the heart and reduces oxidative stress, which supports the claim's general idea that it helps prevent heart disease, even though it doesn't detail the exact biological pathways for plaque stability.
