Pycnogenol is an antioxidant plant extract from the bark of a French maritime pine tree. The tree grows exclusively along the coast of southwest France in Les Landes de Gascogne. Pycnogenol has been found to contain procyanidins, bioflavonoids, and organic acids -- all of which enhance good health naturally. Pycnogenol has been studied for the past 35 years, and there are more than 220 published studies and review articles that conclude it is safe and effective.
