Although resveratrol occurs naturally in grapes (especially Muscadine), nuts and other fruits, buying resveratrol as a supplement means that it is extracted from the herb Polygonum cuspidatum. The resveratrol from Polygonum cuspidatum is just like that of grapes and other sources of resveratrol, but unfortunately, Polygonum cuspidatum is known to be a toxic herb when consumed over time.
Avoiding Polygonum Cuspidatum
In Asia, Polygonum cuspidatum is used as a medicinal herb for snakebites, but it is not meant to be taken for a prolonged period of time, and certainly not for a lifetime.
Most dietary supplement companies do not FULLY extract the resveratrol from the Polygonum cuspidatum raw material. They leave half of their extracted powder as a Polygonum cuspidatum extract.
Look at the label closely when buying resveratrol, there is a good chance you will find that it is a 25-50% extract of resveratrol – which means that half or three quarters of the material is actually Polygonum cuspidatum extract.
Resveratrol can be safely taken over a lifetime as a tonic, but not if you are taking a brand that is also so concentrated with Polygonum cuspidatum.
Seek Pure Trans-Resveratrol
The good news is, when you take a pure trans-resveratrol product, you are getting virtually no trace of Polygonum cuspidatum, and you get all of the naturally occurring compounds that make resveratrol so wonderful. There are probably hundreds of these beneficial compounds, but 3 that are predominant are Catechins, Quercetin, and Ellagic Acid.
Catechins are potent antioxidants that support immune, lung and cardiovascular functions.
Quercetin is a flavanol and one form of the better-known bioflavonoids. It is a very potent antioxidant with many established health benefits.
Ellagic Acid is an antioxidant with a wide range of actions and benefits and is an antioxidant also found in pomegranate and strawberries.
Evidence is rapidly building that certain antioxidants act synergistically to support the cells of the body and to support and maintain the healthy functioning of bodily tissues. Resveratrol is a perfect example of this.
Our friends at Dry Farm Wines tell us that we will find the highest concentrations of resveratrol in Pinot Noir and St. Laurent. Enjoy natural biodynamic wines; in commercial wine the filtering agents, stabilizers, and clarification process all strip wine of resveratrol molecules!!
