I think we should all learn about the benefits of resveratrol. It’s present in grape skin. We are hearing about it more and more because several animal studies have shown that it prevents development of cancers of the skin, breast, esophagus, intestine, colon and prostate. To get the same dose of resveratrol used in the mice studies, a person would have to drink over 60 liters of red wine every day! 
Foods with resveratrol include grapes, blueberries and cranberries. Peanuts also have resveratrol.
Wine and related beverages are a particularly good source of concentrated resveratrol. Here’s a list of high-content wines:
A good dose is from 10 mg-50 mg of resveratrol each day. The “anti-aging” dose is 100 mg daily.
So why am I bringing this up on my fertility blog? A recent study (read more about it here: http://www.ncbi.nlm.nih.gov/pubmed/21248286) has shown that resveratrol may have positive effects on the lining of the uterus and therefore positively affect the outcome of pregnancy and favor fertility.
Just something to think about.
Is there a particular brand of resveratrol that you recommend? When I look at the ingredients some are not grape skin, etc.
