Endurance. It’s the power to sustain, without giving way. When your activity level triggers the “burn,” you can quit and go home. Or, you can overcome the muscle fatigue with RĒ-FŪL ENDURANCE™ and keep pushing onward.
PREMIUM GRADE ENDURANCE FUEL
RĒ-FŪL ENDURANCE™ is a departure from typical “endurance” formulas. No laundry list of obscure ingredients, only what will efficiently support your endurance activity. Nothing more. It has sodium and potassium bicarbonates, shown in research to boost endurance potential. Then we charged it with genuine CarnoSyn® to help reduce exercise “burn.” RĒ-FŪL ENDURANCE is non-flavored and can be added to your favorite beverage as an endurance booster. However, optimal absorption may be achieved when RĒ-FŪL ENDURANCE is combined with 3:2:1 Hydration Base.
