The Effect Of Grape Seed Extract On The Central Nervous System

Grape seed extract is obtained when wine and grape juice is made. It has very powerful antioxidants like poranthocyanidin which is an antioxidant. These molecules are required to protect our skin against sun damage and also improve the vision. It makes the joint flexible and strengthens the blood vessels. It also improves brain function and can prevent several central nervous system conditions. Grape seed has several other health benefits too. However, people with certain existing conditions should consult their doctor before they start consuming it.

The extract protects the brain from degenerative conditions, like Alzheimer's. It contains flavonoids and antioxidants, and offers 20 times the benefits of vitamins E and C, which are well-known antioxidants. The author of a book entitled Change Your Brain, Change Your Body says grape seed extract reduces one-third of the protein deposits that accumulate in the brain.

Grape seed prevents cognitive decline and degenerative diseases, such as Alzheimer's disease, by supplying polyphenol antioxidants. A study conducted on laboratory rats was published in 2008, in the Journal of Neuroscience, and it claimed that grape seed prevents protein deposits accumulation in the brain. Animals that were fed with the extract showed less decline of brain and in cognitive functions compared to the animals that were not fed the extract. The protein scars in the brain are associated with Alzheimer's.

The Pediatric Research published an article in 2007 which stated that the extract is beneficial for protecting the brain from injury and damage. The seeds have excessive antioxidants that offer neuro protective benefits and also prevent the loss of oxygen and blood deprivation to the brain. They also reduce inflammation, lower the body temperature and prevent the oxidation of lipids. The tissue in the brain is protected.

Grape seed extracts prevent ageing by decreasing the levels of oxidized lipids in the brain. It can prevent damage to blood cells, according to an author who wrote the book called The Alzheimer's Answer: Reduce Your Risk and Keep Your Brain Healthy. But the effects of grape seed extract on dementia are not known. There are no conclusive results that suggest whether the extract can treat or prevent dementia.

A supplement of 50 mg per day is recommended for antioxidant effects. Some doctors even recommend 150 to 300 mg of the extract for therapeutic effects. However, a person should always contact the nutritionist before beginning supplements of grape seed extract on their own.

Is Grape Seed Extract Good for the Eyes?

Grapes have been an integral part of human culture and cuisine for thousands of years. They provide a highly nutritious food source and have been used, along with the leaves, in various folk remedies for conditions ranging from sore throat to cancer, according to the University of Maryland Medical Center. Grape seeds, chock full of powerful antioxidants, have caught the interest of scientists and the health-conscious public and may offer benefits for a variety of health conditions, including some related to visual health.

Night Vision

Night vision may improve with grape seed extract supplementation, the University of Maryland Medical Center reports. A study published in the April 2012 issue "Current Eye Research" found that antioxidants in grape seeds protect cells in the retina, which are responsible for your ability to distinguish colors and to see in low-light conditions. In the tissue culture study, grape seed extract quenched free radicals, reversed oxidative damage and protected retinal cells from stress-induced early demise.

Macular Degeneration

Oligomeric proanthocyanins in grape seed extract may help prevent or slow the development of macular degeneration, a condition involving loss of the central field of vision, according to medicinal chemistry lecture notes from the University of Washington. Dr. Theresa Graedon, co-author of "The People's Pharmacy Guide to Home and Herbal Remedies," recommends grape seed extract for slowing macular degeneration as well as reducing visual stress caused by computer screens. Doses of 50 to 100 mg per day are common for general health and wellness. Therapeutic doses for particular conditions may go as high as 300 mg per day.

Cataract Prevention

Cataracts might be preventable, in part, by grape seed extract use, according to a tissue culture study published in the January 2011 "Molecular Vision." In the study, grape seed extract reduced oxidative damage to human lens cells exposed to hydrogen peroxide. Researchers concluded that grape seed extract may be useful for preventing or reversing oxidative damage that can lead to cataract formation. A laboratory animal study published in the June 2006 issue of "Journal of Cataract and Refractive Surgery" found that doses of 100 mg per kilogram body weight of grape seed proanthocyanidins effectively prevented cataract formation. Further clinical trials are needed to confirm these preliminary results.

 

Considerations

Safety of grape seed extract was addressed in a laboratory animal study published in the March 2001 "Research Communications in Molecular Pathology and Pharmacology." Short-term testing showed that grape seed extract was safe when given in single doses as high as 5,000 mg per kilogram body weight. Long-term tests showed that grape seed extract produced no toxic effects to the brain, heart, intestine, kidney, liver, lung or spleen at doses of 100 mg per kilogram body weight for 12 months.

Researchers Find That Grape-Seed Extract Can Kill Cancer Cells

A recent study has found that grape-seed extract may be what the medical community has been looking for to help eradicate cancer cells. In fact, the study concluded that grape-seed extract can indeed kill leukemia cancer cells.

The study, conducted by researchers at the University of Kentucky, is causing quite a bit of interest within the medical community and has been published in an American Association for Cancer Research journal called Clinical Cancer Research. The study was led by Xianglin Shi, Ph.D., a professor at the University of Kentucky, in the Graduate Center for Toxicology Department.

Many researchers are trying to find something that can eradicate cancer cells, with the stipulation that the same thing that can eradicate cancer cells will not have a negative effect (or any effect) on normal cells. Many are saying that grape-seed extract is the answer, though some think it is too soon to tell and are not sure the extract is chemo-protective.

During the study, Shi exposed leukemia cells to grape seed extract at different doses. In one of the high doses the extract caused apoptosis, which is the cell signaling pathway associated with the use of the extract causing death of the leukemia cancer cells. During they study they also found that grape seed extract had no affect on normal cells at all. In addition, within 24 hours of exposure to grape seed extract, over 75 percent of leukemia cells had died.

After the results, researchers wanted to find out how grape seed extract provoked apoptosis. To find out they used genetic and pharmacologic approaches to uncover that grape seed extract powerfully activates JNK (a regulating protein for the apoptotic pathway), as well as the JNK pathway. The JNK pathway controls the cell cycle.
More studies will be done to decide whether or not grape seed extract will be incorporated into leukemia and other cancer treatment and prevention. Many in the medical community are hopeful that the extract will indeed help eradicate cancer cells.

The Health Benefits of Grape Seed Extract

Grape seed extract is a liquid or powdery substance that is derived from the small seeds of red grapes. Occasionally, grape seed extract may come from the skins of red grapes. Grape seed extract is a rich source of flavonoids, which are phytochemicals that contain antioxidant properties. Many people believe that these flavonoids are just as vital as vitamin C and vitamin E to maintaining health.

A supplement rich in cancer-fighting properties

Antioxidants are substances that help the body to remove free radicals, which are cancer causing agents. Free radicals are unstable oxygen molecules that can contribute to the development of numerous harmful conditions in the body. This is the reason grape seed extract supplements that are rich in antioxidants have become popular.

The most valued of flavonoids found in grape seed extract are procyanidolic oligomers or proanthocyanidins (PCOs). Aside from their powerful antioxidant properties, PCOs are also reported to improve blood circulation. The PCOs from grape seed extract are believed to strengthen blood vessels, resulting in improved heart function and a reduction in cancer cells.

Health benefits of grape seed extract

European doctors often prescribe drugs containing PCOs for vascular disorders. Aside from grape seed extract, PCOs are also found in maritime pine. PCOs drawn from maritime pines have the same health benefits and therapeutic benefits as PCOs drawn from grape seed extract. However, maritime pines are more expensive and have a more limited supply than grape seeds.

Taking grape seed extract can help improve blood circulation, which help prevent leg cramps, diabetes complications, varicose veins, numbness in the extremities, muscular degeneration, cataracts and impotence. Because most of these health conditions more commonly occur and are severe among the elderly, grape seed extract can be especially beneficial to them.

Grape seed extract is also believed to partially block the release of prostaglandin, the substance responsible for causing pain and inflammation in disorders such as endometriosis.
Grape seed extract is commonly used as an ingredient in European facial creams. When used as a topical ointment, grape seed extract is believed to help maintain the skin's elasticity.

The antioxidants in grape seed extract help protect muscle cells attacked by free radicals. As a result, those who wish to reduce the painful symptoms of fibromyalgia often take grape seed extract. Although the exact cause of fibromyalgia is not yet known, its painful symptoms include chronic muscle pain and stiffness.

Countless studies have shown that antioxidants play some part in reducing the number of cancer cells in the body. Because of this, people who are at risk for cancer often use grape seed extract. It is believed that the antioxidants in grape seed extract neutralize cell mutations that lead to tumor formation. It is hoped that by taking grape seed extract, the progression of common cancers such as lung cancer, breast cancer, prostate cancer, colon cancer and skin cancer can be halted.

Buying grape seed extract

Grape seed extract supplements are available in many forms and they are generally inexpensive. These supplements can be purchased in tablet, liquid or capsule form. The standardized formula for the grape seed extract should be labeled as 92% or 95% PCO.
