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.

NSI® L-Arginine is better because it:
- Contains a high potency dose of 1,800 mg of l-arginine per 2 capsule serving.

Pregnant or lactating women, diabetics, hypoglycemics, and people with known medical conditions and/or taking drugs should consult with a licensed physician and/or pharmacist prior to taking dietary supplements.
