Grape seed extract is a highly effective natural antioxidant extracted from grape seeds, rich in polyphenols and proanthocyanidins.
In the last century, people used grape seed extract to treat diseases. Now, grape seed extract powder is widely used in health foods and functional foods. Canada has allowed grape seed extract (oligomeric proanthocyanidins) to be used as a supplementary food raw material.
