Allergy Research Group - L-Arginine 500 mg - Free Form Amino Acid Blood Vessel - 100 Vegetarian Capsules

L-Arginine is considered a semi-essential amino acid, and is involved in hormone release, the production of nitric oxide, and the metabolism of ammonia waste in the urea cycle.* Nitric oxide plays many roles in the body, such as supporting normal, healthy blood flow to the brain and other tissues, enhancing muscle oxygen use during exercise, and supporting immune health.* Since 1979, Allergy Research Group has used only the purest, and whenever possible, lowest allergy potential natural ingredients available. Many very sensitive individuals who react to supplements in general can tolerate Allergy Research Group products. Strict quality control procedures are followed in every stage of production, including inspection, manufacturing, packaging, and storing. Allergy Research Group fully discloses all active and inactive ingredients on every product label, allowing you to make informed choices for your nutritional support. Physicians and healthcare practitioners around the world depend on Allergy Research Group for their patients' nutritional support. This brand originated with the ground-breaking oxidant/antioxidant work of Stephen Levine, Ph.D., as one of the first to introduce truly hypoallergenic nutritional supplements in the United States.
