OPCs (oligomeric proanthocyanidins) are a type of flavonol, which include polymers of catechins and epicatechins. Proanthocyanidins are among nature's most powerful antioxidants and are several times more potent than vitamins C and E, our most significant source of dietary antioxidants.
Optimised Extraction Process Without Chemical Residues
OPC extracts can be produced using controversial solvents such as n-hexane, acetone and methanol. However, we perform only the purest possible extractions, using only water and food grade ethanol, thereby avoiding the potential for harmful chemical residues.
