   Ⅵ.  What's Grape Seed 

Grape seed is rich in oligomeric proanthocyanidin complexes (OPC), which is a powerful antioxidant. In addition to the ultra rich potence of over 20 times higher than Vitamin C, it is also 50 times better than Vitamin E. It helps to strengthen the immune system, and also slowdown the aging process, which is of very high market value. Proanthocyanidin B2, which is the most active compound to neutralize free radicals that cause aging, is available only in Grape Seed. In Europe, OPC from grape seed proanthocyanidins extract has been adopted and used for several decades as a safe and effective compound.


  • Since ancient Greece people have used grapes, grape leaves, and sap for health purposes. Grape seed extract was developed in the 1970s.
