Barrons Article- Polyphenols and Resveratrol Get More Publicity

An article (subscription access) in Barrons this weekend:

"Healthy Returns – How to Live Longer"
"Special Report: Retirement -- Eight things to do to live longer and minimize the aches and pains of aging." By MARY PINKOWISH

Touches on the usual things: Exercise, eat right, lose visceral fat, and then what caught my eye- "Your Choice: Eat or Drink Your Polyphenols"

Ha! I have posted many times in many places how friendly I am towards polyphenol supplements. Especially Resveratrol (and EgCG).

From her article: "Evidence has been building for 20 years that at least in some animals, extreme caloric deprivation triggers a process that curbs degenerative aging. Most people would find the amount of required caloric restriction (about 30%) too hard to maintain. But scientists have found that a chemical called resveratrol, famously present in red wine, may mimic the effects of caloric restriction.

Earlier this month, Richard Weindruch, a professor at the University of Wisconsin-Madison Institute on Aging, and colleagues published a study in the online journal PLoS One showing that resveratrol may delay aging in mice at lower doses than previously thought. "No other nutrients that I'm aware of have the ability to increase maximum life expectancy in mice. It's striking," says Weindruch. The findings, he adds, suggest that resveratrol and other polyphenol compounds "have the ability to oppose multiple aspects of aging."

Good stuff.

As always, if you choose to supplement, you must be very careful to read your labels. Purity and potency are critical. Low quality resveratrol (50% or less) contains a lot of (a byproduct of manufacture) called emodin, a powerful laxative! Relentless Improvement brand Resveratrol is a 98% extract. The emodin level is nearly undetectable.

Low quality EgCG supplements are standardized to a low percent of polyphenols. Relentless Improvement brand EgCG Green Tea Superpotent Extract is standardized to an astounding 99.31% polyphenols. And free of residual processing solvents (yuck).

Be a smart shopper and understand that quality is the most important aspect of your buying decision.

Happy Weekend-
