Our take on the Spring Valley L-Arginine Amino Acid Supplements, 500 mg, 100 Count, 2 Pack

Spring Valley L-Arginine is a 500 mg capsule supplement sold as a twin pack of two 50-count bottles. L-Arginine is an amino acid the body uses to make nitric oxide, and the label markets it for cardiovascular support. The formula skips gluten, wheat, milk, lactose, sugar, soy, yeast, preservatives and artificial colors and flavors, and stays under 5 mg sodium per serving. It suits adults who want a simple, free-of-common-allergens arginine capsule and are fine with the label's suggested two capsules three times daily between meals.
