THE NITRIC OXIDE - ENDURANCE CONNECTION EO2 VMAX features nitric oxide (NO) elevating ingredients for a truly novel approach to endurance support. NO is a powerful regulator of optimal circulation, nutrient delivery to working muscles, and tissue repair. However, NO may play an even greater role in endurance-specific performance. Emerging research reveals that NO plays a key role in regulating endurance muscle power, may help extend the time to exhaustion during exercise, and may help alter the oxygen (O2) cost of exercise (support improved VO2 Max).*

PROACTIVE PERFORMANCE OPTIMIZATION During a competition, each athlete’s performance is a direct reflection of his or her pre-race preparation. Those with a proactive approach to training and nutrition become quickly apparent – they are the ones ahead of the competition, and by a wide margin. EO2 VMAX is the ideal choice for “proactive”, endurance-optimizing supplementation. Taken daily, EO2 VMAX helps to build the body’s endurance capacity for peak performance. EO2 VMAX supports nutrient-circulating blood flow, helps improve VO2 Max, nutritionally builds ATP stores, helps build stamina and endurance, and helps the body adapt to stress and fight fatigue.*
