Poor circulation has been tied to a lack of an adequate amount of nitric oxide, which is needed for your blood to move throughout your body efficiently. Nitric oxide is found in your body and can be obtained from foods and supplements. The amino acids citrulline and arginine help boost nitric oxide and expand vessels, allowing blood to flow freely. You can increase your nitric oxide levels and boost circulation by eating foods containing these amino acids.

You can find citrulline in beans, garlic, watermelon, salmon, chicken, cucumbers, eggs, tuna, and cantaloupe. Adding seafood, nuts, spinach, legumes, whole grains, and soy to your plate can give you good sources of arginine.
