Arginine is a conditionally essential basic amino acid involved primarily in urea metabolism and excretion, as well as in DNA synthesis and protein production.* It is an important precursor of nitric oxide (NO) and thus plays a role in the dilation of blood vessels.* Natural color variation may occur in this product. Review: how to neutralize its bad taste - just mix with one big lemon and half glass of water. it taste will totally go away. Review: Horrible taste. But good product - The product is great for the gym. But the taste is so bad that it's very hard to consume. You can forse yourself to drink it. But I think I product should be enjoyable to drink not to force yourself to take it. ## Features - Same trusted quality with a brand new look! Packaging may vary - PROTEIN METABOLISM*/NITRIC OXIDE PRECURSOR*: Arginine supports protein metabolism and is heavily involved in muscle metabolism through its role in the maintenance of a proper nitrogen balance.* Mix 2 level teaspoons daily as needed in at least 8 oz. of juice or water, preferably on an empty stomach. - The Informed-Sport seal is your assurance that each and every production run of these NOW Sports products has been tested for banned substances by LGC, a globally recognized assurance program for anti-doping in sports nutrition products.
