What Does OPC Grape Seed Extract Do and How Does It Work?

Grape Seed Extract INCI Name VITIS VINIFERA SEED EXTRACT EINECS ELINCS No 284-511-6 CAS 84929-27-1 Oligomeric Proanthocyanidins OPC Polyphenols photo picture image Grape seed extract contains chemicals known as Polyphenols, (including the subclass of proanthocyanidins), which are recognized to be effective antioxidants. Substances thought to protect body cells from damage caused by a chemical process called oxidation, which produces oxygen free radicals; antioxidants are believed to work in a number of ways. They may lessen oxidation, they may inactivate oxygen free radicals, and/or they may restore at least some normal functioning to tissues damaged by oxygen free radicals.

 For example, results from human case reports and some laboratory and animal studies appear to show that grape seed extract may help to prevent and treat heart diseases such as high blood pressure and high cholesterol. By limiting oxidation, antioxidants in grape seed extract may help prevent damage to blood vessels and other changes that may contribute to the development of heart disease. Substances in grape seed extract may also block the effects of enzymes that process fats ?including cholesterol ?from the diet. Less fat may be absorbed and more may be eliminated from the body. Other research shows that grape seed extract may help to prevent or control damage to body cells that is caused by drugs, pollution, tobacco, and other toxins. While all of these studies appear promising, much more research ?including long-term studies in humans ?is needed to confirm initial findings.

 Proanthocyanidins are also believed to block the deterioration of blood vessels, therefore, grape seed extract may improve conditions involving veins and arteries. It has been used to prevent, delay, and treat a condition known as chronic venous insufficiency, which occurs when valves in the veins that carry blood back to the heart are weak or damaged. The blood that collects in the veins of the legs can lead to varicose veins, spider veins, or sores on the legs. Results that are more serious may include blood clots in the legs or sores that do not heal and may become infected. This blood vessel strengthening effect of grape seed extract may also help to prevent and treat hemorrhoids.

 Since proanthocyanidins in grape seed extract strengthen the walls of all blood vessels, they may also help to keep damaged, stretched, or stiff blood vessels from leaking. In one area of research, grape seed extract may be effective for slowing retinopathy, the gradual break down of the retinas in the eyes ?usually due to blood vessel damage. Individuals with arteriosclerosis (a build up of fatty deposits in the arteries), diabetes, or other conditions that increase the likelihood for damage to the small blood vessels in the eyes are more likely to have serious vision problems as a result of that damage. Grape seed extract may also reduce eye stress caused by bright lights. In studies of laboratory animals, it has shown some possible effectiveness in preventing cataract formation, but further study is needed to determine whether this effect may pertain to humans.

 One of the polyphenols contained in grape seed extract is called resveratrol. In laboratory and animal studies, resveratrol from grape seeds has appeared to interfere with cancer cell growth and division, as well as causing some cancer cells to disintegrate faster than they would ordinarily. In addition, it may also block enzymes that prolong the survival of several cancer cell types. As a result, tumors may either stop growing or actually shrink because higher than usual numbers of cancer cells die. Therefore, resveratrol may have direct anticancer activity. It may also increase the effectiveness and/or lower the side effects of drugs currently used for cancer chemotherapy. One possible result is that taking resveratrol during chemotherapy may allow lower doses of cancer drugs to be effective, thereby limiting the potential for debilitating side effects. A similar effect was seen in laboratory studies of grape seed extract against HIV, the virus that causes AIDS. Although the exact ways that grape seed extract may fight HIV and other viruses are not known, it is thought that grape seed extract interferes with viral multiplication, possibly by preventing viral attachment to host cells. How high doses of resveratrol and other chemicals in grape seed extract may affect normal human cells is not yet known.

 Grape seed extract may also have topical uses. In preliminary research, grape seed extract appears to be moderately effective for preventing tooth decay. It is believed to delay or stop the breakdown of sugars in the mouth and also to inhibit the growth of certain oral bacteria that may play a role in forming dental cavities. In other studies, injuries to the skin of laboratory animals may have healed better when grape seed extract was applied. Through several possible effects that include promoting the regrowth of connective tissues, grape seed extract is believed to encourage faster, stronger healing with less scarring.

 Oil pressed from grape seeds is used as a dietary supplement. It contains a relatively high percentage of linoleic acid, which belongs to a group of nutrients known as essential fatty acids (EFAs). The body needs EFAs to regulate activities that include heart function, insulin utilization, and mood balance. However, the body cannot produce EFAs, so they must be obtained from foods or dietary supplements. EFAs are thought to block the production of chemicals that promote the formation of deposits in the blood vessels. Consequently, blood pressure and blood cholesterol levels may be lowered and the risk of heart disease may decrease. Additional studies are needed to confirm the effects of both linoleic acid and grape seed oil for lowering the risk of heart disease.

 Grape seed proanthocyanidins have been found to have a number of antioxidant activities in the laboratory. These include scavenging of hydroxyl and peroxyl radicals, and inhibition of the oxidation of low-density lipoprotein (LDL). The inhibitory potential related to lipid peroxidation appears to increase with the degree of polymerization of the molecules. That is, grape seed proanthocyanidins with a greater number of catechin and epicatechin units appear to have more potent inhibitory activity than those with fewer catechin and epicatechin units. Further, the position of linkage between inter-flavan units also appears to influence lipid peroxidation inhibitory activity. Procyanidin isomers with a 4-6 inter-flavan linkage appear to show stronger inhibitory activity than those with a 4-8 linkage. Finally, the presence of a gallate group also appears to affect the inhibitory activity of the procyanidins with respect to lipid peroxidation. A procyanidin dimer with a gallate group linked at the 3-hydroxy position appears to show much greater inhibition of lipid peroxidation than a dimer without such a group.

 Grape seed proanthocyanidins have shown anti-inflammatory, anticarcinogenic and anti-atherogenic activities, again in the laboratory. These activities are thought to be due, in large part, to the antioxidant activities of these molecules. These proanthocyanidins have been found to be cytotoxic for some human cancer lines in culture. Upregulation of apoptosis by the proanthocyanidins in these cancer lines is another possible mechanism for their possible anticarcinogenic activity.

 Proanthocyanidine can scavenge free oxygen radicals and inhibit lipid oxidation; in other words, it has antioxidative properties. Grape seed extract is considered effective in treating the diseases listed below.
