Similar Assertions

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.
