What is Grape Skin extract?

Grape skin extract are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid, and OPCs. Typically, the commercial opportunity of extracting grape seed extract constituents has been for chemicals known as polyphenols, including oligomeric proanthocyanidins recognized as antioxidants.

Grape skin extract is rich in Oligomers Procyanidin Complexes (OPC) , which is a powerful antioxidant. In addition to the ultra rich potence of over 20 times higher than Vitamin C. Grape skin extract is also 50 times better than Vitamin E. Grape skin extract helps to strengthen the immune system, and also slowdown the aging process, which is of very high market value. Procyanidin 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 skin extract proanthocyanidins has been adopted and used for several decades as a safe and effective compound. Grape skin extract has no record of any acute or chronic toxicity, no harmful reaction even under very high dosage. For these reasons, grape skin extract proanthocyanidins has become a new star in the food supplement market.
