Resveratrol scam? Here are the facts.
Dr. Stephen Chaney is a professor of biochemistry and
nutrition at the University of North Carolina - Chapel
Hill. His name is on over 80 published studies in
scientific and medical peer-reviewed journals and he
teaches nutrition to medical students at the UNC.
Q: Everyone seems to have a resveratrol product nowadays.
Why is Vivix better than all those resveratrol products on
A: The answer to that question is really three-fold.
In the first place, the resveratrol in Shaklee's Vivix is
a higher potency, higher purity preparation than many of
the other resveratrol products on the market.
Dr. David Sinclair's studies were a shock to many
scientists in the resveratrol community. He showed
convincingly that the amounts of resveratrol one needs to
have a substantial beneficial effect were orders of
magnitude greater than anyone expected. Clearly, one or
two glasses of red wine per day won't do the trick.
Similarly, many of the older resveratrol products on the
market just aren't potent enough to be of any significant
For those resveratrol products that are potent enough,
many aren't pure enough. There is a naturally occurring
contaminant in impure resveratrol preparations that has a
laxative effect. Unless the resveratrol preparation is 99%
pure or better, many people will find that the side
effects outweigh beneficial effects.
But the most important reason is that resveratrol cannot
do it all. It is just one of many naturally occurring
polyphenols, which is why Shaklee added a polyphenol blend
from muscadine grapes to their purified resveratrol.
For example, Shaklee's polyphenol blend is high in ellagic
acid, which is not found in significant amounts in red
wine or most resveratrol preparations.
Ellagic acid inhibits an enzyme that is involved in the
formation of advanced glycation end products (AGE
proteins), one of the central four mechanisms of cellular
aging. Resveratrol has no effect on this enzyme, but does
block the other three key mechanisms of cellular aging.
Similarly, animal studies suggest that ellagic acid shines
in preventing gastrointestinal cancers, while resveratrol
and other components of the polyphenol blend that Shaklee
uses prevent a variety of other tumors.
The bottom line is that by adding a polyphenol blend
containing ellagic acid and other protective polyphenols
from the muscadine grape to their ultrapure, ultrapotent
resveratrol, Shaklee has developed a product that is
clearly superior to either resveratrol or a muscadine
polyphenol blend alone.
This is not a "one plus one" addition, but a synergistic
combination of protective polyphenols that is far more
protective than any one of them alone.
Now you should have enough information to decide for yourself....
