Pycnogenol is an extract from French maritime pine bark (Pinus maritima), and is considered to be a strong and direct antioxidant and therefore is used as a dietary supplement. Pycnogenol is claimed to alleviate inflammations, improve cardiovascular function, inhibit tumor initiation, and inhibit angiotensin-conversion enzyme. It has been suggested to take part in the prevention of some degenerative diseases such as diabetes, cancer, and atherosclerosis due to its ability to protect body cells from damage by reactive oxygen and nitrogen. No studies are available to support ergogenic or health benefits in athletes.
A mixture of antioxidant chemicals derived from the French maritime pine, Pinus pinaster especially atlantica, marketed as “pine bark extract” for a variety of disorders.
