  • RESVERATROL: For The First Time Researchers Call For The Public To Begin Mass Consumption Of This Red Wine Molecule

    March 20, 2011: by Bill Sardi

    GlaxoSmithKline (Sirtris Pharmaceuticals) may have abandoned further research on its SRT501 resveratrol pill, but that hasn’t dampened ongoing research of this red wine molecule.

    Researchers in Australia now say there are a “plethora of laboratory investigations which provide evidence for the multi‐faceted properties of resveratrol and suggest that resveratrol may target ageing and obesity-related chronic disease by regulating inflammation and oxidative stress.”

    Researchers at the University of Queensland (Australia) say the first in vitro (lab dish) and in vivo (living organisms) scientific evidence has certainly confirmed a role for nutra-pharmacology in health.

    The data provides justification for the daily consumption of resveratrol and other plant-based chemicals containing food‐ products as part of disease prevention, which may ultimately be the reason why these bioactive compounds do exist in nature,” the researchers said.

    They go on to say “nutraceutical resveratrol is easily available commercially, and uncontrolled self‐prescribing is encouraged by claims that resveratrol mimics a calorie-restricted diet and has anti-aging activity.”

    This is the first bold recommendation for widespread public use of resveratrol.  While stating that resveratrol is “is still in the dawn of clinical investigation,” these researchers are essentially steering the public to navigate around modern medicine which has yet to embrace resveratrol.

    Take in the broad applications for resveratrol and its wide influence over the human genome (library of genes), as pictured in the following two graphics.

    Actually, research showing resveratrol is the most profound weapon against cancer dates back 13 years.  How long will it take to translate basic research into applied science?  Answer: it won’t happen until resveratrol is molecularly reconfigured into a patentable drug.  (Actually, this is already underway.  See prior report on combretastatin, a resveratrol-like molecule derived from bark of the African bush willow tree, made by Oxigene).

    The Australian researchers indicate the dietary intake of resveratrol can reach 6-to-8 milligrams per day with consumption of red wine, grapes, berries, peanuts and other foods.  Dark aged red wine is the most concentrated source, providing 100-1000 times more resveratrol than plant foods.  The best red wine will provide ~1 milligram of resveratrol per 5-ounce glass.  Unfiltered red wine, just now being offered by some vintners, may provide even more.

    Nutriceuticals that provide resveratrol are offered in a very broad dosage range, from 20 to 1000 milligrams, making it difficult to ascertain the amount needed to promote health versus treat disease.  Excessive dosage (more than 350 mg) appears to be counterproductive.

    The Australian researchers say it is “too soon to comment on the most suitable dose and source, or the effects and safety of chronic intake, until further clinical data is available.”

    But one brand of resveratrol, Longevinex®, has undergone extensive animal study showing it produces health benefits at relatively low dose (~100 mg resveratrol human equivalent dosage) and, unlike plain resveratrol, does not exhibit toxicity even at high dose (~2800 mg).  In animal studies, Longevinex® has been shown to exert 9-fold greater genomic response than plain resveratrol and doubled blood flow in the first blood vessel outside the heart (aorta) following a chemically-induced heart attack compared to resveratrol.  A human study in Japan also showed Longevinex® abolishes the first sign of arterial aging (Kansai Medical University, Osaka, Japan, in publication).  – © 2011 Bill Sardi, ResveratrolNews.com

    Abstract

    Nutrapharmacology, or the use of bioactive food compounds at pharmacological dose is emerging as a therapeutic approach to target the complex metabolic dysregulations in ageing and obesity-related chronic disease. Resveratrol, a polyphenol found in the skin of grapes, and other edible plants and related food products, has received extensive attention through the link with the French paradox, and later with its chemopreventive activity demonstrated in-vitro and in animal cancer models. A plethora of laboratory investigations has provided evidence for the multi-faceted properties of resveratrol and suggests that resveratrol may target ageing and obesity related chronic disease by regulating inflammation and oxidative stress. A number of obstacles stand in the path to clinical usage however, not least the lack of clinical evidence to date, and the myriad of doses and formulations available. Further, data on the effects of resveratrol consumption in a capsule versus food form is conflicting, and there are uncertain effects of long-term dosing. The review will summarize the human pharmacokinetic and pharmacodynamic published data, and the topics for research if resveratrol is to become a multi-target therapeutic agent addressing chronic disease.

    I have been taking Longevinex for 4 months now, and I would be interested in finding out what number, if any, of my longevity genes are expressing as a result. Any idea how to go about that and what the cost might be. I suppose that Longevinex uses some Affymetrix gene chip?

    Reply: well, the problem is that you would need to offer up some live tissue for analysis. The analysis would only be applicable to that tissue. A baseline study would be required, that is, gene switching analysis prior to taking a product like Longevinex. This is why animal testing is performed, because they need to slay the animals, take their heart, brain, liver, etc. tissue and mix it in a blender and then analyze it for proteins. I maintain that gene testing is not the end-all. Genes only react to environmental triggers, they don’t have a mind of their own. We know there are certain biological stressors, such as modest doses of solar or ionizing radiation, mild oxygen deprivation, food deprivation (fasting, not to the point of starvation) that trigger a profound and unequaled biological response, turning on defensive mechanisms that produce imperviousness to pain, resistance against mortal heart attacks, profound mental capacity, resistance against infection. There are molecular ways to mimic this without resorting to food deprivation or exposure to radiation or sitting in a hypobaric chamber. Resveratrol is a key molecule that provokes this defensive response. Vitamin D is another. We know that resveratrol and quercetin both release adenosine and heme oxygenase, molecules that protect the heart and brain from periods of oxygen deprivation (heart attack, stroke). Resveratrol and quercetin provoke the production of nitric oxide which dilates (widens) blood vessels, controls blood pressure and improves circulation. Vitamin D provokes an army of neutrophils (a type of white blood cells) to respond to infection within minutes. With this being said, why haven’t the masses run to take resveratrol pills? God only knows. It would seem foolish not to take resveratrol pills given this knowledge. -Bill Sardi
