The secret of "the French paradox" in a capsule! For decades, scientists were mystified by what they called "the French paradox"—the fact that the French enjoyed good cardiovascular and overall health in spite of the high fat content of the French diet. Researchers now attribute this phenomenon to the antioxidant polyphenols found in red wine, including proanthocyanidins and resveratrol, Swanson Ultra Resveratrol Complex delivers these powerful antioxidants in much higher concentrations than you could ever get from red wine. It features an extract of nature's best resveratrol source, the Chinese herb Polygonum cuspidatum, along with alcohol free red wine extract and grape seed extract.
