Does Resveratrol Act As An Anti-Aging Supplement To Enhance Longevity
February 16, 2009 by admin · Leave a Comment
Resveratrol is a chemical that is found naturally on the skin of red grapes, of the polyphenol family that includes such other members as the powerful antioxidants anthocyanadin and the flavanoids. They destroy free radicals that are responsible for many ill effects in the body, including cardiovascular disease and aging. Aging occurs through the destruction of body cells that free radicals initiate, and can theoretically be retarded by the destruction of the free radicals.
Free radicals are becoming more common invaders of our bodies due to their increasing concentration in the atmosphere through vehicle and aircraft emissions, and also of our seas and rivers through industrial effluents. Free radicals are also created by excessive radiation, such as the harmful UV content of sunlight that is no longer effectively filtered by an adequate ozone layer.
Resveratrol is known to be effective against cardiovascular diseases due to its anti oxidant properties, and also for other reasons, but it is also believed to be a possible anti-aging supplement, to beat off the effects of old age. There is the obvious reason of it being a very powerful anti-oxidant and so preventing cell damage through the effects of free radicals, but there is more to it than just that.
The French do not seem to possess a longevity beyond that which could be expected from their diet high in saturated fats and alcohol. The fact that most of that alcohol is in the form of wines, especially red wines, is significant, but their high cheese intake with its cholesterol and saturated fat content, and other highly saturated animal fats, would be expected to cause a much lower average life expectancy that that which is actually normal in the area.
Although resveratrol is commonly found on red grape skins, and is a constituent of red wine, the quantities are small and it is the Japanese Knotweed that is the major natural source. Resveratrol is currently manufactured from knotweed, which is the main source of the supplement in health food stores. In fact you can purchase online what is described as ‘>99% pure knotweed Resveratrol that is not contaminated with plant residues.’ A lot depends on your viewpoint I suppose!
Perhaps the biggest contribution to be made to longevity by resveratrol is that it can activate the SIRT1 gene. This is the gene that activates the protein and enzyme sirtuin. Sirtuin is thought to be what is loosely terms a ‘protector of cells’ and helps cells to repair themselves when they are close to destruction. When the cell is not sure whether to carry on with the struggle or just give up and die, sirtuin persuades it to fight on and to repair itself. Without the sirtuin, the cell would have died, and as cells die, one ages.
However, the amount of resveratrol found in red wine is insufficient to activate the SIRT1 gene that has to be active before the sirtuin is activated, and supplementation is generally needed. The SIRT1 gene is also activated by a calorie reduced diet, and this can also help to protect cells from dying under stress. Such diets are useful in some situations, but will not necessarily prolong life for those that adopt it.
The SIRT1 enzyme is also thought by some to increase the activity of the mitochondria, the power packs inside cells that provide them with energy by processing fats. Mice fed with resveratrol appeared full of energy that was consistent with a surge in the number and efficiency of the mitochondria within their body cells. This is supported by an increase in muscle tissue. If this is true, and studies on this are continuing, then resveratrol fed to humans could also increase their energy as they age, since the aging process coincides with a reduction in the number and efficiency of the mitochondria within the cells.
This could also tie up in a way with the calorie controlled diet, since an increase in the metabolism that comes with increased mitochondria activity results in a higher calorie uptake, and so a reduction in the free calories available in the body. However, one of the mysteries of the human body is that what makes logical sense does not necessarily work in fact, and so the jury will remain out until the results of the large number of studies underway have been published.
For example, more evidence is required to prove the mitochondria activity theory unequivocally although all of the evidence so far tends to support it. At the moment resveratrol has restricted known uses, though the evidence is being collected and accumulated to provide support for the theories that exist on its ability to help us live longer and with more energy.
As more studies are carried out over the next few years, it seems highly likely that many more beneficial effects will be discovered, and those we are aware of confirmed by scientific proof. Resveratrol has many medicinal properties in addition to its beneficial effect on aging, such as its antioxidant properties, and ability to destroy free radicals, its anti-inflammatory properties where it is of benefit in the treatment of conditions such as arthritis and other inflammatory conditions, and also its effect as an antiseptic agent.
It is already known to increase the longevity of fruit flies, yeasts and worms and results on mice are just as encouraging. The theory behind its effect on human longevity is valid science, and it is known that if cells have a longer time to repair broken DNA, then they are able to do so. The enzyme sirtuin does this, and that is activated by the SIRT1 gene that is turn is activated by resveratrol. So the theory works, and so far laboratory tests are supporting this theory.
Whether or not resveratrol helps us to live longer or look younger as we age is not yet known, but studies are under way. Since the material is natural and not a prescription drug, there is nothing to prevent you from using it, but you are advised to consult your doctor before trying out medication that you have not taken before.

Resveratrol Supplements and the Benefits of Resveratrol in Fighting the Aging Process

Valerie Rosenbaum asked:
Most resveratrol supplements are not worth the investment. While researchers have shown many resveratrol benefits in the laboratory, the nutrient must reach your bloodstream in order to perform its magic. The latest research indicates that it does not usually make it to the bloodstream.
They have tested people’s blood after drinking wine on an empty stomach, drinking it with food and taking uncoated resveratrol supplements. None of these caused a significant increase in the levels of trans-resveratrol in the bloodstream.
All of the studies concerning resveratrol benefits were conducted using trans-resveratrol. The supplement with the highest trans-resveratrol content is standardized to a 50% concentration. If an enteric coating is applied, this type of supplement can increase the blood level of trans-resveratrol, but most companies don’t use the right form and they don’t include an enteric coating.
You won’t get any resveratrol benefits from a powder or liquid form. You might get some by drinking red wine, but researchers believe that the benefit of red wine is not due to its trans-resveratrol content. The amount that you would have to drink to significantly affect circulating blood levels would be damaging to the liver.
So, resveratrol supplements are a good idea, as long as the manufacturer uses the right form, combines it with other important nutrients and wraps the whole thing up in an enteric coating, to insure that it reaches the upper intestine, where it can pass through to the bloodstream.
Some of the resveratrol benefits include a healthier heart, a reduced risk of cancer, better functioning metabolism and possibly an extension of your lifespan, if the results of the laboratory studies can be transferred to humans.
No one is sure how or why it works in the ways that it does. There are only theories.
One of the most convincing is that trans-resveratrol increases the activity of a gene that can reduce a free radical known as superoxide. Superoxide molecules are not highly toxic, but they can, over time, cause DNA degeneration.
If this theory is correct, resveratrol supplements should include vitamin C, enzymes and glutathione. The gene reduces superoxide to hydrogen peroxide, which is also a free radical. Vitamin C and other ascorbates, reduce hydrogen peroxide to water. If glutathione and enzymes are also present, vitamin C remains more active for a longer period of time.
Some of the better supplement manufacturers include the right combination of antioxidants and other nutrients to provide the greatest effect. Resveratrol benefits are included among them.
There are hundreds of different nutrients and plant extracts that are known to be beneficial to human health. It would be nearly impossible to include all of them in your diet. Some of them are not plants that we normally eat. Extracts from marigold, for example, are known to protect the eyes from oxidative damage. When was the last time that you ate a marigold?
So, supplementation is important and necessary, if you want to live the longest, healthiest life possible. But, single-ingredient resveratrol supplements are not your best choice for supplementation.
