Resveratrol in red wine

Resveratrol might help prevent damage to blood vessels and prevent blood clots. It may lower low-density lipoprotein (LDL) cholesterol. That is the "bad" cholesterol.

But study results on resveratrol are mixed.

Some research shows that resveratrol may make you less likely to get blood clots and swelling and irritation, called inflammation. This can lower the risk of heart disease.

But other studies have found that resveratrol does not protect against heart disease. More research is needed.
