Can I Take Resveratrol along with Quercetin?
Q I just read about another company that sells resveratrol, and states that taking products containing quercetin along with resveratrol blocks the effects of the resveratrol. I am taking a multivitamin, multimineral, antioxidant formulation which contains quercetin and was planning on ordering your resveratrol but am now wondering how, or if, I should take both.

A The epidemiological data on red wine show that when it is consumed in modest amounts, it is clearly beneficial. Resveratrol, found in red wine, may depend for its bioavailability on the presence of the myriad other compounds (including many other polyphenolics) with which it coexists in red wine. That’s because these compounds help inhibit its metabolism to sulfates and glucuronides in our bodies, thus maintaining resveratrol’s antioxidant, and other beneficial functions. In fact, one of the other dominant polyphenolics in red wine is the flavonoid quercetin, which has been found to inhibit the action of some of the enzymes responsible for disarming resveratrol. Thus resveratrol and quercetin complement one another.
One thing more, quercetin has many extraordinary health properties, including the ability to inhibit enzymes known to cause more aggressive, fatal types of cancer in the human body.
