The Study
Evidence for the Benefits of Melatonin in Cardiovascular Disease
This article is like a teacher summarizing what other scientists have found about a sleep supplement and heart health. It doesn't run new experiments itself, so it can't prove that melatonin definitely fixes heart problems in people. It just points out interesting patterns and ideas from past studies.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
This review explains how the sleep hormone melatonin acts like a shield for your heart, fighting off damage from stress, poor blood flow, and harmful chemicals.

Quality score
Systematic reviews and meta-analyses of cohort studies. They sit above a single cohort study but below a single randomized trial, because the underlying evidence is still observational.
Key takeaways
Summary
Based on the study abstract and findings.
- 1These findings suggest melatonin could be a helpful supportive therapy for heart health, but human dosing and long-term effects still need more clinical testing.
- 2Animal and lab studies show melatonin reduces heart cell death, lowers blood pressure, stabilizes heart rhythm, and protects energy-producing parts of cells from damage.

Melatonin works like a powerful body-wide cleaner and protector, helping blood vessels stay healthy and reducing cellular damage caused by stress throughout your organs.
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.
Taking melatonin supplements may help the heart pump better and prevent damage in people with heart failure. It works by slowing down scar tissue buildup, protecting heart cells from dying, and helping the heart regulate blood pressure and energy use more efficiently. This could lead to stronger heart contractions and less muscle wasting.
Giving melatonin helps protect the heart from the severe damage caused by sepsis. It works by calming cellular stress, keeping energy production running, and reducing harmful inflammation, which ultimately helps patients survive and keeps their hearts pumping better.
Melatonin works like a powerful internal cleaner that protects your heart cells from damage caused by stress and aging. It does this by neutralizing harmful molecules, boosting your body's natural defenses, and keeping the energy-producing parts of your cells running smoothly.
Taking melatonin can help prevent dangerous heart rhythm problems after the heart experiences a lack of oxygen or low potassium levels. It works by protecting heart cells from damage and keeping their electrical signals stable.
