QUALITY COMES FIRST The KQ brand provides consistently pure products, leveraging Kyowa's 60 years of experience. Quality assurance forms the core of the KQ brand. L-Arginine is a non-essential amino acid, which means that under normal conditions it can be synthesized by the human body to meet its needs. In case of poor nutrition or strenuous physical activity, the body is no longer able to produce enough Arginine, so some amount should be consumed through food or supplements. Being the only precursor of Nitric Oxide (NO) and an important precursor of Creatine, Arginine supplementation is generally practiced by athletes and bodybuilders.
