Improves blood flow to the genital area by dilating blood vessels and helping the penis to enlarge to its full capacity, thus increasing the size, hardness, and frequency of erections. L-Arginine is a precursor of nitric oxide (NO) in the human body. In the 1990s, scientists discovered that not only is NO an essential compound that helps blood circulation, but it is important to normal sexual function in both men and women. Without L-Arginine there would be no NO, and without NO, men would not be able to have erections.
Moreover, the positive benefits of L-Arginine goes beyond sexual enhancement. This remarkable amino acid helps build muscle mass, enhance immune function, improve blood pressure, increase memory, and speed wound healing. L-Arginine-derived NO has also been found to play a supporting role in the cardiovascular, immune, and nervous systems and has been validated by hundreds of studies.
