Resveratrol improves heart function

Resveratrol, from red and purple grape skins, is an anti-inflammatory antioxidant with heart-health benefits.

Doctors in this study wanted to see if resveratrol would improve heart function in those with a previous heart attack, and gave 40 such people 10 mg of resveratrol per day, or a placebo. After three months, while there were no improvements for placebo, in the resveratrol group, the left heart ventricle was better able to relax and fill with blood, blood vessels were more flexible and able to dilate, red blood cells were more effective in delivering oxygen, and LDL cholesterol levels significantly improved.
