Resveratrol: Greatness from Grape Skin and other Powerful Plants
We know that our customers, like us, are keenly aware of the health news circulating in the media. That's why we believe it's important to address one of the latest hot topics with you here.
You may have heard the recent news reports heralding resveratrol as a promising agent in the fight against aging. Our product development team formulates new products and spends thousands of hours poring over the research behind today's most promising supplements. Resveratrol and grape seed extracts have always stood out from the rest.
The reason is simple: good research. The story of resveratrol begins in the 1980s, when scientists first identified what they called "the French Paradox." They applied this title to define what epidemiological research indicated, but which they could not explain: While the French people enjoy rich foods high in fat, they appear to enjoy good cardiovascular fitness and other measures of healthy aging.
Later, as more researchers became fascinated by this "paradox," it was determined that the country's love of wine—red wine, in particular—was the reason behind the observations. But could wine really be healthful? Could it really allow the French to enjoy their croissants, while helping to maintain good heart health at the same time?
Further research showed that yes, wine could, in fact, provide a certain level of dietary protection. The seeds of grapes contain antioxidants in the form of polyphenols and proanthocyanidins, which became the focus of "French Paradox" investigations. Then, things got really interesting.

Just as the scientific community was embracing the overwhelming evidence showing that grape seed polyphenols and proanthocyanidins did indeed nourish and protect the heart and other important aspects of health, a new agent was discovered. Resveratrol was identified not in the seed but in the skin of the grape, opening up a whole new avenue for scientific inquiry.
Now we have the new report that's swept the media from coast to coast— a Harvard scientist saying resveratrol is the most promising substance ever found to protect our health from the results of poor dietary and lifestyle habits. You can read an abstract of the study at the online home of the journal Nature at www.nature.com.
At Swanson we have a variety of grape-derived resveratrol supplements from which to choose. However, grapes do not hold an exclusive over this exciting nutrient, and in fact, significant and powerful amounts of resveratrol are also found throughout the plant kingdom such as the Japanese knotweed (Polygonum cuspidatum). Whichever source you choose, be assured that Swanson products are independently tested for purity and potency, and are the best quality supplements available for the lowest price possible. It's our mission and our guarantee to you.

Resveratrol is getting a lot of positive press in the mainstream media. What can you tell me about your resveratrol products?
We’ve read the latest reports surrounding resveratrol, a potent polyphenol found in grapes, wine, peanuts, mulberries and other plants. Specifically, resveratrol is a phytoalexin, a compound that acts as a plant’s natural defense system. The current media hype focuses on red wine as the primary source of resveratrol; however, only relatively small amounts naturally occur in red wine. Depending on the growing conditions, the type of red wine produced, and many other factors, an ounce of red wine could contain anywhere from 14 micrograms to as much as 284 micrograms. Regrettably, for fans of Chardonnay, white wines do not contain measurable amounts of resveratrol; unlike the reds, they’re not exposed to the resveratrol-containing grape skins in the winemaking process. Our Swanson Ultra® Resveratrol Complex combines standardized red wine and grapeseed extracts with another potent plant source of resveratrol, Polygonium cuspidatum.
Most resveratrol in dietary supplement form comes from Polygonium cuspidatum, commonly called Japanese knotweed, Mexican bamboo or wild rhubarb among many other names. Often vilified for its invasive growing behavior throughout the US and Europe, this Asian herb is used in traditional Japanese and Chinese medicine for vascular and immune health. We offer Polygonium cuspidatum for all-natural cardiovascular and antioxidant protection with our 50 mg High Potency Resveratrol and 100 mg Super Potency Resveratrol.
