First Endurance continues to stay at the forefront of endurance nutrition with the development of the EFS endurance bar. With the new EFS endurance bar, you get the same award-winning EFS drink formula in a great tasting bar that provides ALL the ingredients you need to maximize performance. Like the EFS drink mix, EFS bars are fortified with clinically effective doses of the amino acids Glutamine, Leucine, Iso-leucine and Valine to improve glycogen resynthesis and delay central fatigue. It also provides 200% RDA of Vitamin C to enhance the body’s immune function, fight free radicals and keep you healthy for future training and racing. The EFS bar is made with all natural ingredients and (when possible) organic ingredients.

The EFS bar is the first bar formulated to maximize performance while exercising. It’s the only bar that provides an ideal mix of maltodextrins and simple sugars as the primary fuel source. Clinical evidence shows that a mix of carbohydrates significantly improves oxidation
and absorption over any single source of carbohydrates. Plus, each EFS bar gives you all five electrolytes (over 1,000mg/bar), in the levels endurance athletes require to prevent cramping and maximize endurance. So there’s no longer the need to supplement
with additional electrolyte pills or add anything else to your bottles anymore.



First Endurance sponsored cyclists, triathletes, runners and swimmers have worked closely with First Endurance on the development of the new EFS
endurance bar. First Endurance sponsored athletes and teams started testing
the prototype bars early in 2006. After initial testing, these athletes gave the First Endurance R&D team important input and feedback on the bars. This feedback was compiled and evaluated and the appropriate
changes were made to ensure the bar is exactly what endurance athletes require for racing and training. Nothing else even comes close.
