THE NITRIC OXIDE CONNECTION EO2 EDGE features nitric oxide (NO) elevating ingredients for a truly novel approach to endurance support. NO is a powerful regulator of optimal circulation and nutrient delivery to working muscles. 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).*

ENDURO TRI-ENERGY COMPLEX As the Enduro Tri-Energy Complex releases exercise fuel, research backed nutrients promote nutrient-delivering blood flow, oxygen transport and energy-yielding ATP production. Next, advanced ingredients and electrolytes support cell hydration and counter the effects of free radicals. These factors help fuel the endurance extending, fatigue-fighting power of EO2 EDGE.*

ADVANCED ENDURANCE OPTIMIZER* CLINICALLY TESTED INGREDIENTS

During a marathon, the metabolism in an endurance athlete’s body can increase to 2000% above normal, and oxygen utilization may elevate by up to 1500%! Additionally, fluid loss, electrolyte depletion & free radical damage are a constant threat to peak performance.*

THE ENDURANCE EDGE Endurance athletes are a unique breed – they thrive in a training zone few dare to enter.

The advanced, research backed EO2 EDGE formula incorporates ingredients that may help support:* ~ Efficient Fuel for Active Muscles* ~ Optimal Blood Flow* ~ Natural RBC Support for Peak O2 Availability* ~ Muscle Recovery from Training Induced Stress* ~ Optimal Muscle Contractions and Increased Time to Exhaustion* ~ Restoration of Body-Hydrating Fluids*

ADVANCED NUTRITION FOR THE ENDURANCE “EDGE”

EO2 EDGE was expressly developed to address these endurance factors and more. EO2 EDGE delivers a Tri-Source energy blend, supports improved oxygen transport and utilization, boosts ATP energy, offers nitric oxide boosting exercise extenders (NBEE), and provides key electrolytes.*

EO2 EDGE is the ideal choice for pre, intra, and post-performance fueling to meet the demands of high-intensity, long duration bouts of exercise and competition. Push your mental and physical limits with EO2 EDGE.*
