BELOW - THE LATEST, UGLY, NEWS ABOUT BOGUS RESVERATROL:

If you start to compare red wine resveratrol pills, it won't take you long to find there is a real war going on between brands of these pills. And you, consumers and users, are the losers.

With a straight face, some newer brands tell us there is no need to preserve resveratrol in dietary supplements and that under normal environmental conditions, e.g. 70-80 degrees fahrenheit, in room light, and in room air, resveratrol is stable. For this super-size-me falsehood, we award the Resveratrol Users acclaimed HORSESCHIDT TROPHY.

Scientists we have contacted in the wine and dietary supplement industries confirm trans resveratrol is vulnerable to degradation of photo-isomerization, meaning conversion by UV radiation to a different molecular form that is known as cis resveratrol. And cis-resveratrol is a form which DOES NOT activate the Sirtuin 1 DNA-repair/survival gene.

One brand has the word "resveratrol" boldly printed across its front label, but when asked, its maker conceded it contained grape skin that wasn't standardized for resveratrol so there was no way of knowing how much resveratrol it provided, if ANY. 

Our ENORMOUS COWPIE TROPHY is bestowed on another widely-promoted brand which shows a brand-comparison chart, claiming its product has more "red wine extract" than other brands on the chart. Sounds cool, right? WHOOPS: This cowboy brand never reveals if it actually provides resveratrol. Their ad even goes on to claim it exclusively provides resveratrol from Bordeaux grapes from France. Golly Gee Wow - France!  BUT WAIT: WHEN THE PRODUCT ARRIVES AT YOUR DOOR AND YOU LOOK WITH ANTICIPATION AT THE PRODUCT'S ACTUAL LABEL - that promised alleged Bordeaux French resveratrol featured in their ad is NOT found on its label.

In fact, this company's actual bottle label reveals it provides resveratrol from Giant Knotweed (Polygonum cuspidatum), not grapes. Knotweed is a very acceptable source. But why all the cowpie stuff in their ads ???

Another brand says it provides the only "pure" resveratrol, but it also is a 50% extract from Giant Knotweed (Polygonum), not the pure 99-100% resveratrol extract it claims to be.

THE WEB GOES ROUND THE WORLD. AND IN MANY NATIONS, ANYTHING GOES.  Ads on the worldwide Web are often stunning in their ad claims for their brand of resveratrol pills. Many ignore USA FDA rules, claiming their resveratrol pills will help a person lose weight or cure diabetes. This may be true, but it's not yet proven by any human studies thus far. In fact, virtually all of the resveratrol pill makers are using "borrowed" science, since there are no published studies yet on any resveratrol dietary supplement, though there are many significant studies involving red wine or lab-grade resveratrol in animals.

So be careful: Many bottles of red wine actually provide little or no resveratrol - a fact also true for many brands of resveratrol , regardless of their label claims or advertising claims.
