Researchers at the University of Exeter discovered taking a dietary supplement like Bio-Synergy L-arginine may enhance the production of nitric oxide in the body which can significantly boost stamina during high-intensity exercise. The study, published in the August 2010 Journal of Applied Physiology, suggests taking the supplement can allow athletes to exercise up to 20 percent longer.
