Resveratrol Extract

Resveratrol is part of a group of compounds called polyphenols. They’re thought to act like antioxidants, protecting the body against damage that can put you at higher risk for things like cancer and heart disease.

It’s in the skin of red grapes, but you can also find it in peanuts and berries.

Manufacturers have tried to capitalize on its powers by selling resveratrol supplements. Most resveratrol capsules sold in the U.S. contain extracts from an Asian plant called Polygonum cuspidatum. Other resveratrol supplements are made from red wine or red grape extracts.

It’s thought to help reduce inflammation, lower LDL or "bad" cholesterol, and make it more difficult for clots to form that can lead to a heart attack. It could limit the spread of cancer cells and start killing them. It may also protect nerve cells from damage and fight the plaque buildup that can lead to the disease.
