Proanthocyanidins are also known under several other names, among the most common: OPC, pycnogenols, and leukocyanidins. Proanthocyanidin is a name for a class of bioflavaniods. 

  • at 100-200 mg/day this subset of flavonoids found in grape extracts, green tea, red wine and dark chocolate improves vascular function, with benefits seen for heart, blood circulation and brain health. 

In 1936, this bioflavinoid was classified and referred to as Vitamin P, although it didn’t gain official vitamin category status. The common link between the bioflavaniods, of which there are about 20,000 different ones, is that they contain a benzene-pyran-phenolic acid molecular nucleus (referred to as flavin) as part of their much larger molecular structure. Proanthocyanidins have been sold as nutritional/therapeutic supplements in Europe for almost a quarter of a century. Their introduction to the United States has been relatively recent.

The discovery of proanthocyanidins can be attributed to Professor Jacques Masquelier. Dr. Masquelier spent almost a half century researching proanthocyanidin. He also invented the extraction techniques by which proanthocyanidins are obtained from plants rich in these substances.

Much of the research and documentation for the known and suspected effects/benefits of proanthocyanidins comes from many of the European research institutes and universities.
