  • The comparison test has been performed on epithelial (Caco2) cells which is the first cell type through which oral ingredients cross into the body (intestinal barrier).
  • The unit of measurement is the concentration of the ingredient necessary to enable a standardized antioxidant efficacy. Thelower concentration of ingredient points to a higher antioxidant capacity.

Grape seed proanthocyanidin extract is a far more powerful antioxidant than vitamins E, C and beta-carotene[2].
