Can you say Oligomeric Proanthocyanadin:
How about grape Seed Extract

Grape seed extract is an extremely powerful natural antioxidant; some say at least 50 times more effective than vitamin E.  What can be said about resveratrol goes double for the extract of red grape seeds since resveratrol is contained in the grape seeds.  

The secret of grape seed extract's power is oligomeric proanthocyanadin (OPC), a strong antioxidant nutrient of the flavonoid family of catechins (think green tea).

Red grapes are grown for wine, grape juice, jams, jellies and other grape based products but the seeds don't usually end up in the food or drink.  

Once the grapes are harvested, the pulp, skin and seeds are separated. The seeds are then cleaned and dried in preparation for harvesting the oils from the seed.

The area of interest here is what grape seed derivatives can do for our health and wellness.  

As one of the more potent antioxidants, it has been shown in numerous research studies to promote cardiovascular health and provide protection to the brain from inflammation.  That would indicate positive implications for stroke and cognitive impairment.  

It has also been shown to promote skin and eye health, plus exhibits both antiviral and antibacterial properties.
