Natural sources:Oligomeric Proanthocyanidins.

Oligomeric Proanthocyanidins OPCs INCI Name Vitis Vinifera Seed Extract CAS 84929-27-1 EINECS ELINCS No 284-511-6 glycosidic anthocyanidins,monomeric flavan-3-ol catechins and flavan-3,4-diol units,antioxidants,free radical scavengers photo picture image Proanthocyanidins are found in high concentrations from such sources as: cranberries, grape skins, grape seeds, pine bark, lemon tree bark, and hazel nut tree leaves. The two most common and richest known sources are grape seed extract and pine bark extract. It has been indicated that grape seed extract may be a better choice because: 1) It yields a 10% higher concentration of proanthocyanidins. 2) Grape seed extract contains a specific proanthocyanidin with a higher degree of oxygen free radical scavenging potential. This proanthocyanidin is designated as Proanthocyanidine B2-3'-0-gallate.

There is little doubt as to the powerful antioxidant properties of proanthocyanidins. In vitro research has confirmed that they are 50 times more effective than vitamin E and 20 times more powerful than vitamin C. Proanthocyanidins also prevent the oxidation of vitamin C to dehydroascorbate by providing hydrogen ions which reduce glutathione - keeping the levels of the active for of vitamin C (ascorbate) higher. One aspect, relating to oxygen toxicity effects on the brain and CNS, which proanthocyanidins have, is they can penetrate the blood-brain barrier better than certain other antioxidants.
