Grape Seed Extract Scientists have discovered that cain nutrients can help you look younger and feel healthier. An important nutrient in the quest for anti-aging and anti-disease treatment is Grape Seed Extract.
Youthful Eyesight - Vision Research Declining vision is common with aging. According to a recent clinical study proanthocyanidins may play a role in improving vision. In a research study, 100 people who were free of eye defect and eyes disease were given 200 milligrams of proanthocyanidins daily for four weeks. The subjects were tested for their resistance to blinding and their eyesight in dim light. 98 out of 100 test subjects showed an improvement vision; as a result of supplementing with proanthocyanidins. Additional Features and Benefits of Grape Seed Extract Grape Seed Extract offers maximum antioxidant protection and numerous health benefits. Global Nutrients Grape Seed Extract contains 50 mg of Proanthocyanidins per capsule. Grape Seed Extract and Pycnogenol® have recently generated considerable attention in the natural health community because both are extremely rich in a class of powerful antioxidants known as oligomeric proanthocyanidins (OPCs). According to scientists, OPCs are 50 times more potent as antioxidants than either Vitamin C or Vitamin E. Since oxidative damage may play a role in many degenerative diseases (heart disease, cancer and arthritis) and has been implicated in the aging process, OPCs' abilities to scavenge free radicals could prove valuable in the human quest for optimal health. OPCs seem to have many benefits; for example, they are very effective in protecting the fibrous structural proteins known as collagen and elastin from degradation. In this way they promote the strengthening of the flexible connective tissues throughout our bodies. It is perhaps this function that accounts for the restorative effects of OPCs that scientists have observed in studies involving capillary fragility, vascular disease, diabetic retinopathy and joint degeneration. Scientists also attest to the ability of OPCs to inhibit histamine production. This ability may be of interest to those suffering from sinusitis, asthma and allergies, since histamine has long been known to contribute to these conditions through its important role in the inflammation process.
Pine bark extract is sold in the United States under the
registered trademark name of Pycnogenol® (held by Horphag research Ltd.
of Switzerland). It contains at least eighty five percent OPCs. A
higher percentage of OPCs can be found in Grape Seed Extract which
contains ninety two to ninety five percent OPCs. Studies conducted by Jacques Masquelier (w was the
discoverer of OPCs) show that Grape Seed Extract has a greater
antioxidant effect than pine bark extract. This is probably due to one
particularly potent kind of OPC (proanthocyanidin B2-3'-0-gallate)
found in Grape Seed Extract that is completely absent from pine bark
extract. Further studies show that Grape Seed Extract's superior
antioxidant qualities protect the cardiovascular system better than
pine bark extract. One such study conducted by Jonadet et al. compares
the cardio-protective activities of the extracts of grape seeds,
bilberries and pine bark. The study was conducted by introducing a free
radical compound into the circulatory system of rs, and then measuring
the cellular damage caused to arterial walls. The researchers observed
four groups of rats; a control group and three groups, each of which
were administered one of the extracts. The results showed that of the three extracts studied,
Grape Seed Extract provided the arterial walls with the best defense
from free radical damage. Specifically, Grape Seed Extract's protection
was 22% greater than pine bark extract and 15% greater than bilberry
extract. Grape Seed Extract Is A Better Value Pine bark has many natural contaminants (sap secretions,
bird droppings and other air borne pollutants) and requires
considerable effort and expense to clean, inexpensive byproduct of the
wine industry. Additionally Grape Seeds yield more OPCs per kilogram
than does pine bark. These factors have combined to make the cost of
pine bark extract more than double that of grape seed extract. On the basis of OPC content, cost and effectiveness,
Grape Seed Extract clearly performs better than Pycnogenol®. This has
led it to outsell pine bark extract 50-to-1 in Europe. |
