Grape Seed Extract and Oil Benefits

The main benefit of grape fruit seed extract comes from chemical compounds it contains called proanthocyanidins. Proanthocyanidins also called PCOs for procyanidolic oligomers or OPCs for oligomeric procyanidins are a class of nutrients belonging to the flavonoid family.

Proanthocyanidins exhibit strong antioxidant effects and play a role in the stabilization of collagen and maintenance of elastin used to create connective tissue that is used to support internal organs, blood vessels, joints, and muscle. Analysis of the results of studies indicate that proanthocyanidins may be useful in reducing the duration of edema after face-lift surgery from almost 16 days to just about 5 days. Other studies have provided preliminary evidence to support the belief that proanthocyanidins can also have certain anti-mutagenic effects.

Proanthocyanidins have demonstrated some positive effects on vision in healthy people and have shown to possibly prevent or even reverse abnormal blood clotting in smokers. (Note: 200 mg was the daily dosage used in the vision study)

Proanthocyanidins can be found in many plants, most notably pine bark, grape seed, and grape skin. However, grape seed, cranberry, black currant, green tea, black tea, and other herbs also contain proanthocyanidins. Nutritional supplements containing proanthocyanidins extracts from various plant sources are available alone or in combination with other nutrients in herbal extracts, capsules, and tablets.
