How Does NSI® L-Arginine Work?
L-arginine is an amino acid that plays an important part in the body’s production of nitric oxide. Nitric oxide promotes vasodilation (relaxation of blood vessels), helping to maintain healthy blood flow throughout the body. Because of this effect, l-arginine is considered useful for concerns that improve with enhanced circulation, including men’s sexual health. Did You Know? All NSI supplements are packaged in HDPE (High Density Polyethylene) bottles. These bottles keep moisture vapor out, protecting the freshness and integrity of their contents, and are 400% more effective compared other brands currently using PET (Polyethylene Terephthalate) bottles. HDPE bottles do not break as glass can and are also recyclable so we urge you to please recycle them.
