Exercise

Both cardiovascular exercise and weight lifting increase the need for oxygen. As a response to this increased need, artery linings release nitric oxide into the blood. This promotes widening of the vessel walls, which increases blood flow and oxygen delivery. Nobel prize-winning Dr. Lous J. Ignarro recommends 20 minutes of aerobic exercise to promote continuous production of nitric oxide, even on your off days.

Reduce Saturated Fats

Saturated fats contribute to arterial plaque, which reduces blood flow and impairs the production of nitric oxide. Foods such as red meats, butter, whole milk and even poultry can contain elevated levels of saturated fats. Therefore, consumption of these foods should be minimized. Ignarro recommends olive oil, fish and flax seed as beneficial substitutes.

Fiber

Foods high in fiber, such as grains, fruits and vegetables, are also rich in antioxidants. These foods reduce cell damage that can discourage nitric oxide production. By maintaining healthy cells, your body will produce more nitric oxide.

L-Arginine

L-arginine, an amino acid, is used to make nitric oxide within endothelial cells. L-arginine can be found in meats, grains and fish but may be at insufficient levels to promote nitric oxide production properly. If you cannot consume the recommended two to three grams of L-arginine twice a day, then you might consider a supplement. If you do, you should include L-citrulline since supplemental forms of L-arginine do not absorb well in the absence of L-citrulline.

Vitamins E and C

Both vitamins E and C reduce cell damage from oxidation, which hinders nitric oxide production. Foods and supplements high in these vitamins promote nitric oxide levels. Foods such as oranges, melons and cucumbers offer such vitamins.
