Designs for Health’s L-Arginine provides 750 mg of the amino acid L-arginine per capsule. L-Arginine serves as a building block for structural proteins, enzymes and other signaling molecules in the body. It is a conditionally essential amino acid, meaning that while the body can synthesize arginine internally, certain conditions may increase the body’s requirement for arginine beyond that which it is capable of generating on its own. L-arginine is abundant in both animal and plant foods sources, but some individuals may benefit from additional amounts via supplementation.
L-Arginine is the precursor to a compound called nitric oxide. Nitric oxide helps support healthy blood pressure by influencing the dilation and elasticity of blood vessels, thus allowing blood to flow more smoothly. Nitric oxide also supports healthy function of the cells that make up the inner lining of blood vessels, called the endothelium.
