## Description

NOW L-Arginine is pharmaceutical grade. 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.

## 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. In addition to production run testing, Informed-Sport-certified products are also blind-sampled at the retail level up to four times annually, and testing results can be found at informed-sport.com.
- GMP Quality Assured: NPA A-rated GMP certification means that every aspect of the NOW manufacturing process has been examined, including our laboratory/testing methods (for stability, potency, and product formulation).
- Packaged in the USA by a family owned and operated company since 1968
