NOW Sports L-Arginine Powder, Pure Amino Acid Nitric Oxide Precursor & Protein Metabolism Support, 1 lb

NOW Sports L-Arginine Powder is a pure amino acid supplement designed for adults and athletes looking to support protein metabolism, nitric oxide production, and active lifestyle nutrition. L-Arginine is a conditionally essential amino acid involved in urea metabolism, excretion, DNA synthesis, and protein production. It also acts as an important precursor to nitric oxide, a compound involved in normal blood vessel dilation. This unflavored powder format makes it easy to mix into water, juice, or a preferred beverage, especially before training or as part of a daily sports nutrition routine. Each 2 level teaspoon serving provides 6 g, or 6,000 mg, of free-form L-Arginine, with about 76 servings per 1 lb container. NOW Sports L-Arginine is pharmaceutical grade, vegan/vegetarian, Non-GMO, Informed Sport certified, steroid tested, and quality tested for athletes of all levels.
