some 400 years later, Professor Jacques Masquelier concluded that pine bark not only contained some vitamin C, but obviously was a good source of bioflavonoids, whose effects are similar to those of vitamin C. Further studies and research revealed that the pine bark contained an array of proanthocyanidins complexes. These compounds were also found in a variety of plants, including grape seeds, cranberries, peanut skin, lemon tree bark and citrus rinds. Masquelier termed the active ingredients of the pine bark "pycnogenols", which today are referred to in the scientific community as oligomeric proanthocyanidins, or OPCs.in 1534, French explorer Jacques Cartier was leading an expedition up the St. Lawrence River. Trapped by bad weather, Cartier and his crew were forced to survive on a ration of salted meat and biscuits. Cartier's crew began to suffer from severe deficiency of vitamin C and showed symptoms of scurvy. Many crewmembers died before the surviving members encountered a friendly Native American who saved most of their lives. He told them to make a tea from the bark and needles of the pine tree to cure their malady. They complied and, as a result, Cartier and many crewmembers survived.some 400 years later, Professor Jacques Masquelier concluded that pine bark not only contained some vitamin C, but obviously was a good source of bioflavonoids, whose effects are similar to those of vitamin C.

oPC 3 contains a combination of oligomeric proanthocyanidins (OPC's) from sources that include grape seed, red wine and pine bark† extracts. The grape seed extract is the superior source of OPCs, containing 92% of active ingredients over pine bark's 84% of active OPC ingredients.The red wine extract contains flavonoids called leucocyanidins from the skin of red grapes. Leucocyanidins are bioflavonoids with powerful antioxidant properties crucial to their role in supporting the circulatory system OPC 3 also contains bilberry and citrus extracts, which are known to have effects of vision and histamine release, respectively.this powerful formula will be delivered to your system the way nature intended it to be - in an isotonic solution that maximizes absorption. OPC 3 has a pleasant natural grape flavor, is a vegetarian product, and mixes instantly when added to water. This product should be taken on an empty stomach for the fastest, most effective delivery of the active ingredient.oPC 3 contains a combination of oligomeric proanthocyanidins (OPC's) from sources that include grape seed, red wine and pine bark† extracts.
