Your body needs protein, which is made up of amino acids, to build and repair tissues and muscles. Arginine, also known as l-arginine, is classified as a conditional amino acid. That means your body can normally make it from other nutrients, but must obtain it from food when under stress, for example, due to illness. This amino acid, which supports wound healing, normal blood pressure and a healthy cardiovascular system, is obtained naturally from a wide variety of foods.

Foods with Protein

Protein-containing foods supply arginine. Among the animal-based foods that contain this amino acid are meats, poultry, fish, seafood, eggs and dairy products such as milk, yogurt and cheese. Nuts, seeds, oats, beans and wheat germ are good plant-based sources of arginine. In addition, NYU Langone Medical Center cites chocolate as providing this amino acid.
