What's Grape Seed Extract Olygemeric Proanthocyanidinss (OPCs)

Grape Seed Extract Proanthocyanidins is natural bioflavonoid powder obtained from ground-up seeds of red wine grapes, Vitis vinifera. Recent years , Grape Seed Extract is prescribed by doctors in several European countries as it is rich in flavonoids, phytochemicals that have antioxidant properties.

Important Reminder: Grape Seed OPC Adulteration

Do you know how serious is adulteration of Grape Seed today ?

Grape Seed Extract(GSE) is a well-known dietary supplement .However, there is a serious adulteration in GSE industry due to the lack of standardized criteria for GSE and rising cheaper proanthocyanidins(OPC) sources.

A scientific study group found that more half of 21 commercially available samples are adulterated with 6 of them are maybe counterfeit. [Very few of the commercial GSE samples contained an overall content of PACs and catechins at a level comparable to authentic GSE, which raises a serious concern," report on Food Chemistry.

Why adulteration of Grape Seed Extract is bad ?

Peanut skin extract and pine bark extract are the most common counterfeits of GSE as they contain high proanthocyanidins .However,there is no scientific evident that these counterfeits possess equal health properties with grape seed OPC ,due to their incongruent proanthocyanidins constituents.Moreover ,using adulteration of GSE with peanut skin extracts may bring serious risk to consumers and the company as Peanut allergy is [one of the most severe food allergies" effecting 1.4% of the population in US.

How to identify adulteration?

The difference between the adulterations and the authentic product is the proanthocyanidins constituents. GSE is found to contain B-type PACs with highest concentrations of catechin and epicatechin while peanut skin extract is composed principally of A-type PACs with negligible quantities of the catechin and epicatechin .Pine bark extract contains both A and B-type PACs, but in much smaller amount than GSE.
Recently , GSE adulteration detection is improving. Organic Herb Inc. developed HPLC Method foridentification of adulteration of GSE.
