It has the most beneficial blend of l-arginine and l-citrulline to enhance the effects of nitric oxide. The body's own natural ability to produce nitric oxide. The ingredients were chosen for their ability to support the body's production of nitric oxide and be an important part of your daily cardiovascular maintenance program.
