Douglas Laboratories Pycnogenol is a dietary supplement for antioxidant support. Pycnogenol is a very powerful, natural free radical scavenger. Its antioxidant activity is more effective than vitamin C and vitamin E. It reduces oxidative damage to vital tissues and supports a healthy capillary system. It provides protection for vitamin C that is used for collagen production; naturally stimulates nitric oxide production in the blood vessels for normal arterial health support; and binds to collagen fibers to provide protection against free radicals which supports maintenance of the natural elasticity of collagen in arteries, capillaries, skin and joints. Recommended use: Take 1 to 3 tablets daily, or as directed by a healthcare professional.
