What is Grape seed Extract?

Grape seed extracts are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid and phenolic procyanidins (also known as OPC or oligomeric procyanidins). Grape seed extract can be applied topically or taken internally, and is the best known source of antioxidants available.

Chemical constituents of Grape seed extract

The main ingredients are procyanidins and OPC 

Grape seed extract is a heterogeneous mixture of gallic acid, monomers, dimers, trimers, tetramers, polymers and other oligomers. The basic building blocks are molecules of catechin, epicatechin, epicatechin gallate, gallic acid esters, glycosides and peptides. Due to the high degree of heterogeneity, several analytical techniques are required to characterize grape seed extract.

6. A resveratrol breast cancer remedy is currently being studied for its efficacy in softening breast cancer tumors after radiation and preventing tumor growth altogether.

7. Antioxidants found in grape seed extract work to repair and strengthen blood vessels, in turn lowering blood pressure.
