All Proanthenols OPC™ products are formulated with 100% bioavailable and 100% residue free Proanthocyanidins (OPC) from Masquelier's OPC including pharmaceutical grade extracts of both grape seeds and pine bark. Other names for OPC are proanthocyanidins, and leucocyanidins.

The OPC in Proanthenols OPC is manufactured and distributed under protection of U.S. Patent Number 4,698,360 assuring today's standard of excellence in OPC. One important reason that Life Plus Proanthenols OPC stands out is the inclusion of CytoFlav-C, a secret blend of synergistic nutrients including Lemon Bioflavonoids, Hesperidin, Rutin, Quercetin and Vitamin C.

They belong to the total family of bioflavonoids, occur in nature with OPC and are a unique plus to these great formulas. The use of high quality patented extracts from both grape seeds and pine bark combined with the other unique synergistic nutrients in CytoFlav-C and the Life Plus PhytoZyme tablet base ensures the very finest in OPC products.

In addition, it only makes sense to take advantage of the various individual catechins that occur in both grape seed and pine bark extracts. Each of them have their value and the Life Plus formula takes advantage of both.
