Many practitioners recommend Nitric Oxide Bodybuilding Supplements for the prevention and treatment of particular age-related diseases, including cardiovascular disease, cataracts, and macular degeneration. In the absence of specific ailments, they suggest a daily dose of 100 milligrams to maintain general health. An extract of the bark of the French maritime pine, sold under the,-brand name Pycnogenol, is equivalent, in my opinion, to cheaper grape seed extract. I do not take either of these. Because my diet is rich in flavonoids from tea, berries and other fruits, vegetables, and dark chocolate, and I already take plenty of supplements. But you might consider these products for neither additional antioxidant support if you are nor consuming enough dietary sources of flavonoids.
