NITRIX is a dietary supplement that is taken throughout the day to promote blood vessel-dilating and muscle-volumizing effects, thereby supporting blood flow and enhanced muscular performance. The key to the NITRIX formula is the inclusion of the amino acid L-arginine, a precursor to nitric oxide. High levels of nitric oxide are known to dilate the blood vessels, which can have a multitude of positive effects on muscular performance and appearance. NITRIX promotes workout performance, endurance and anti-fatigue. Additionally, NITRIX promotes vascularity and muscle pumps. NITRIX lays the groundwork for all further physique and performance improvements. By taking NITRIX throughout the day, athletes ensure that their muscles are operating at their full potential and that they are getting the most out of the time and energy they sacrifice to training.
