Nitrosigine is a patented arginine/silicate complex with powerful benefits for circulatory health. Arginine is a precursor to nitric oxide, the miracle molecule that expands blood vessels to optimize blood flow. Silicon is concentrated within the arteries, where it helps maintain their structural integrity. Nitrosigine provides the benefits of both, along with additional benefits from the unique synergistic combination. Preclinical data clearly demonstrates the superiority of Nitrosigine over standard arginine, with nearly twice the improvement in blood flow in a head-to-head comparison of Bradykinin-induced vasodilation responsefour times greater than the control.
