Nitric Oxide is a sports supplement formulated to improve physical performance, as it contains nitric oxide precursors that promote vasodilation. This allows for greater delivery of oxygen and nutrients to the muscles during exercise, which is especially beneficial during high-intensity and endurance activities, reducing fatigue over a prolonged period of time.

To help achieve better results, Weider has formulated this product enriched with active ingredients L-Citrulline Malate and Beetroot Dry Extract, both known for their ability to produce nitric oxide in the body. This compound helps dilate blood vessels, improving circulation and increasing blood flow to the muscles during exercise, optimizing the delivery of oxygen and nutrients essential for performance.

In addition, it promotes faster recovery by reducing muscle soreness after exercise, as these ingredients help reduce stiffness by eliminating waste products such as lactate and ammonia, which are responsible for the feeling of fatigue and muscle discomfort after training.
