Grape Seed Extract, A Powerful Antioxidant

What Is Grape Seed Extract?

Grape seed extract is a natural plant substance that has a concentrated source of oligomeric proanthocyanidins (OPC). These anti-oxidants help protect cells from free radical damage and also promotes healthy circulation. Grape Seed Extract is rich in polyphenols, a compound that's high in antioxidants. Studies have shown OPC to be more powerful antioxidants than vitamin C, E, and beta-carotene.

Before Grape seed extract was discovered, the best sources of antioxidants came from vitamin C, E, and beta-carotene; however, these sources were not powerful enough to fight the free radicals and are also excreted by the body within a short time of ingestion. Grape seed extract, on the other hand, has been shown to remain in the body for as long as 3 full days, and is 20 times more potent than vitamin C, and 50 times more stronger than Vitamin E.

The research done on Grape Seed Extract first came about in late 20th century from the "french paradox", where the French had very low rates of heart disease, while some of their diet and other factors would contribute to higher incidence of heart diseases. Scientists believed the secret was in their red wine, and further research demonstrated that OPC present in their red wine promotes cardiovascular health, and now, grape seed extract has been found to contain the richest sources of OPCs. It can be said that grape seed extract is one of the most powerful antioxidants available.
