Pycnogenol® is a patented standardized extract from the cortex (the outer part of the bark) of the maritime pine (Pinus pinaster), a pine species that grows on the southwest coast of France.
Pines are also traditionally known as pine. The extract is rich in polyphenols, including various types of oligomeric proanthocyanidins (OPCs) and organic acids (including ferulic acid, cinnamic acid, and caffeic acid).
There is already a long tradition in the use of Pycnogenol. It has been used for 40 years as a nutritional supplement and there is very little research done with this composition.
