Resveratrol pills are a Dietary Supplement
Resveratrol is a compound produced by grapes and other plants in response to environmental stresses. Exciting new research has been done with resveratrol and rodents in terms of their lifespan as recently mentioned in the New York Times, CNN, Time magazine, and other major media outlets. Now you can have your own resveratrol supplement, one of the major active compounds in wine, without having to ingest all the calories found in grapes or wine.
Dr. Ray Sahelian, M.D., who developed this product, is one of the world's leading experts on nutritional supplements. He says: "Until actual human studies are done with resveratrol, we cannot claim this is an anti-aging product. It is best to limit dosage to 10 mg. There is no proof in humans at this time that higher dosages are preferable. Besides, many people are taking a number of other supplements and antioxidants on a regular basis, and it is a good idea not to mix excessive numbers of herbs and nutrients together. We also don't know in any detail the interactions of prescription medications with resveratrol pills."

Resveratrol was first isolated in 1940 as a constituent of the roots of white hellebore, but has since been found in various plants, including grapes, berries and peanuts. Most of the resveratrol supplements on the market come as extracts of the herb Polygonum Cuspidatum. Different extract potencies are available, and a 25 % extract is an excellent choice.
Resveratrol supplement Questions:Q. Does resveratrol have side effects? A. Since human resveratrol studies are minimal, we do not know the full range of resveratrol side effects or benefits at this time. No resveratrol side effects have been mentioned in the medical literature.
Q. I am a bit confused. I have just received my order of resveratrol. From the contents label I understand that each tablet contains 40mg resveratrol. Yet in his newsletter, Dr. Ray Sahelian states "I can only tell you what I plan to do. I will take a 10 mg resveratrol supplement once or twice a week". A. Resveratrol is most commonly extracted from an herb called Polygonum Cuspidatum which has a high amount of resveratrol. The resveratrol product that we have available has 40 mg of this herb, and since it is a 25% extract, each capsule has 10 mg of resveratrol which is what Dr. Sahelian mentioned in his newsletter. Therefore, one capsule a few days a week. or as your doctor suggests, is a reasonable option.
Q. There are so many healthy antioxidant supplements such as acetylcysteine, carnosine, vitamins C and E, berry extracts, etc. How does one know what the appropriate dosage is and how they interact with a resveratrol supplement? Before I buy resveratrol supplements this information would be hepful to me. A. These are no simple answers. One option is to buy a few of these antioxidant supplements and rotate their use or to take a low dosage of each. Taking very high dosage may not necessarily be healthier than taking reasonable amounts. The ideal resveratrol dosage in humans has yet to be determined.
Q. I am very interested in adding resveratrol to my dietary supplements but I came across an article that quotes research that stated that most of the resveratrol taken orally gets converted by the digestive process to other compounds, and thus it's effect on the "longevity" genes is effectively nullified. As an anti-aging product, the article recommended much higher oral dosages to increase the amount of resveratrol that gets absorbed before the digestive juices alter it. So, a formulation of 10 mg seems very paltry in the face of vitamin companies that are hawking 500 and 1000 mg preparations. Will 500 or 1000 mg of trans-resveratrol tablet be more appropriate? Can we find a formulation that lets most of the resveratrol to be absorbed without being affected by the digestive juices? A. Many assumptions are being made here. There is no proof yet in humans that taking a reseveratrol supplement, at any dosage, has an anti-aging effect. Many people, including some scientists, make the mistake of assuming the same benefits in animals will also occur in humans. Keep in mind that when animals are given a compound, they are not taking anything else with it. In contrast, most humans who take a resveratrol pill are also ingesting other supplements, antioxidants, medications, caffeine, alcohol, and additional substances that may interact with the resveratrol pills and give an outcome that is different than that obtained in rodents. Even if resveratrol supplements have a benefit in humans - and we certainly hope they do - the ideal dosage is not clear and anyone who claims they are certain of the right dosage is not being scientifically honest. Furthermore, some antioxidants or beneficial substances, may show early benefits the first few weeks or months and then end up causing toxicity or harm. How do we know that some of the metabolites of resveratrol, when ingested in 500 or 1000 mg dosages, are not harmful? Currently we don't know what effect they have on organs and tissues of the body. Another point to keep in mind is that it is not easy to find 99 percent or 100 % pure resveratrol on the market as is often used in research studies. The resveratrol supplements over the counter are often 10 to 50% extracts of herbs and some companies mislead the consumer by mentioning the total amount of the herb rather than the amount of resveratrol in it. When taking a resveratrol supplement, people are likely ingesting other substances found within the herb, for instance Polygonum cuspidatum, that is present in the capsule,. We don't know the long term benefits and risks of taking this herb or others from which the resveratrol is extracted. A few of us tried 10 mg resveratrol capsules and some of us started having headaches when 4 capsules a day were reached. Mice are not likely to report headaches or other symptoms. For all of these reasons, at this time we suggest using one capsule of this product a few times a week. Additional human research will guide us further.

Study: Improved brain blood flowDr. David O. Kennedy and Emma L. Wightman of Northumbria University, Newcastle upon Tyne, evaluated 22 healthy adults during three study visits separated by at least one week. By the end of the three sessions, each volunteer had received a 250-mg oral dose of trans-resveratrol, a 500-mg dose, and placebo, in random order.After a 45-minute resting absorption period, the volunteers did cognitive tasks previously shown in brain-imaging studies to activate the prefrontal cortex. Resveratrol had no effect on cognitive function, but there were dose-dependent improvements in cerebral blood flow and oxygen extraction. American Journal of Clinical Nutrition, April 2010.
