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 may have a multitude of positive effects on muscular performance and appearance. NITRIX® promotes superior workout performance and, thereby, gains in strength and size. Additionally, NITRIX® promotes vascularity and intense muscle pumps, which may help support the density and appearance of the muscles. Any type of athlete can benefit from improved cardiovascular performance and efficiency. In this sense, NITRIX® lays the groundwork for all further physique and performance supporting improvements.
