Supports nitric oxide synthesis^†

^{Increased demands for L-arginine, a conditionally essential amino acid, can occur during periods of increased physical stress or illness. L-arginine supports growth hormone metabolism, tissue integrity, energy metabolism, and immune function.† It also supports the synthesis of nitric oxide, a molecule produced in all body tissues that serves an important role in the cardiovascular, immune, endocrine, and nervous systems in the body.†}
