Swanson L-Arginine Essential Amino Acid Energy Cardiovascular Support Health Supplement -Free-Form Amino Acid- Nitric Oxide Precursor- 500 mg 400 Capsules -Caps- 2 Bottles

If you're looking for an amino acid to add to your health and wellness regimen, you may want to take a look at L-arginine. Found in various types of red meat, poultry, eggs, fish and dairy, L-arginine is converted by the body into nitric oxide. Once this conversion takes place, the body uses nitric oxide to dilate blood vessels, which helps support healthy blood pressure within the normal range. L-arginine delivers many other health benefits as well, including giving the body an infusion of antioxidants to promote the body's ability to fight free radicals, providing a boost to athletic performance and immunity and supporting sexual health for both men and women. 400 capsules arrive in two bottles of 200 capsules each. Same formula. New look.
