What percentages are the pine and grape contents?
Masquelier’s OPC contains proanthocyanidins from both grape seeds and Maritime Pine Bark. Taking into account economies of scale, seasonal variations in OPC content of grapes and pine, Masquelier’s OPC blend ensures a consistent and maximum content of proanthocyanidins and their different precursors. The actual percentages are proprietary, but the “best of both” is guaranteed as well as the most efficacious and economic balance.
