grapesThere has been a lot of talk about resveratrol and taking it as a supplement. With all the health benefits that are associated with it it is easy to understand why. Claims of reducing the effects of aging to helping you lose weight are just some of the pluses of taking a good resveratrol supplement.

But you might be wondering just what is resveratrol? Resveratrol is a phytoalexin that is naturally produced by certain plants when it is attacked by bacteria and fungi. So basically it is an antibiotic produced by plants to fight off and prevent disease.

Resveratrol is most famous for being found in red grapes as well as red wine. But it is also found in raspberries, blueberries, mulberries, and cranberries as well as others.

While these are all good sources you really cannot get enough from them to get the full benefits that you can from a concentrated resveratrol supplement. Plus some people do not want to drink a lot of wine, if any at all.
