subject: Studies On Resveratrols Effect On Heart Health Produce Promising Results [print this page] Resveratrol really came to the fore around 2006, with a report in the journal, Nature. Researchers at the Harvard Medical School and the National Institute on Aging reported that resveratrol seemed to counteract the negative effects of a high-fat, high-calorie diet and greatly extended the lifespan of mice. Since then, other studies on resveratrol have yielded positive results.
Resveratrol, a naturally-occurring substance found in the skin of red grapes and other plant sources, is thought to be at least partially responsible for the so-called French paradox, the low incidence of cardiovascular disease among the French, who consume a high-fat diet along with a moderate daily intake of red wine.
(Red wine contains more pure resveratrol than white wine, because the amount of this compound present in wine is determined by the length of time the grape skins are in fermentation. Grape skins are removed earlier in the process of white wine production, meaning it contains less resveratrol. Grape juice, which is not fermented, also contains resveratrol, Other sources include peanuts, mulberries, blueberries and cranberries.)
Drinking red wine in moderation has long been considered a way to promote heart health. Needless to say, red wines apparently protective effect on the cardiovascular system has attracted numerous researchers, some of whom focus on resveratrols role in this protective benefit. Red wine, however, has small and varying amounts of resveratrol, about 0.2 5.8mg per liter. To reap the benefits ascribed to resveratrol, one would have to drink about 60 liters of red wine to reach any appreciable dose similar to the ones in the studies.
Since neither the American Heart Association nor the National Heart, Lung and Blood Institute recommend the consumption of alcohol to prevent heart disease, health products, such as resveratrol supplements, are an excellent alternative to those who wish to boost their resveratrol intake.
However, resveratrol supplements vary greatly in concentration, purity and efficacy. This makes it imperative that those who wish to take resveratrol products diligently research the company and type of products they are considering purchasing.
A wide range of resveratrol products are available from PureandHealthy by Nu-ture. Dosages vary, but supplements from PureandHealthy have several distinct advantages over other supplements: first, all their resveratrol products are tested for 98% purity to ensure maximum benefit and the least amount of by-products. Second, PureandHealthy sells micronized resveratrol. (Micronization produces smaller particles which greatly increase the products bioavailability.) Third, supplements from PureandHealthy are in the form of trans-resveratrol, which has greater stability and ease of absorption than the cis-form. Fourth, the company uses only capsules derived from vegetable sources, manufactured using state of the art technology, ensuring that all products are 100% vegan, BSE-free, and Halal and Kosher compliant.
By now more than a mere buzz word, resveratrol is poised to become one of the most widely used health supplements in the market.
