As men age, their nitric oxide (NO) levels drop, leading to poor circulation, and weaker erections, so we launched VigRX Nitric Oxide. Nitric oxide is a physiological signal essential to erections.

Featuring the trusted VigRX brand, this supplement contains a patented ingredient Velox which contains both L-Citrulline and L-Arginine. Numerous clinical studies show the benefits of these ingredients to improving blood flow, helping improve erection quality, sexual stamina, and improving overall blood flow.

Nitric Oxide (NO) is a “messenger” molecule in your body that helps “relax” blood vessels for improving blood flow and blood pressure. This discovery was made in 1998 which awarded 3 pioneering researchers the prestigious Nobel Prize.

These Nobel-Prize-winning researchers led the way for further exciting discoveries revealing the importance of nitric oxide for cholesterol, blood sugar, cardiovascular, blood pressure, and immune system health.

These discoveries also led the way to understanding the science behind achieving hard erections.
