The proanthocyanidins are one of the most beneficial groups of plant flavonoids. The most active proanthocyanidins are those bound to other proanthocyanidins. Collectively, mixtures of proanthocyanidin dimers, trimers, tetramers and larger molecules are referred to as oligomeric proanthocyanidins or OPCs for short.
Extracts of OPCs have demonstrated a wide range of activity:
Increase intracellular vitamin C levels
Decrease capillary permeability and fragility
Scavenge oxidants and free radicals
Inhibit destruction of collagen
Grapeseed extract contains the gallic esters of proanthocyanidins, the most active OPC antioxidant, unlike pine bark extract which does not. Grapeseed extract is also more economical and creates less impact environmentally as only the fruit is harvested.
