Extracted from premium French wine grapes using low-temperatures to preserve its purity, wine grape seed extract is superior to other grape extracts because it contains a higher concentration of oligomeric proanthocyanidins (OPCs)—antioxidants that prevent and control disease by safeguarding cells against the ravages of unstable oxygen molecules (free radicals). Wine grape seeds also produce procyanidolic oligomers (PCOs), which inhibit allergic reactions that can generate skin problems such as eczema. Scientists have demonstrated that wine grape seeds contain more powerful antioxidants than vitamins C, E, and beta-carotene.
