The EFS bar is fortified with clinically effective doses of the amino acids Glutamine, Leucine, Iso-leucine and Valine to improve glycogen resynthesis and delay central fatigue (1,2). 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 (3,4). 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 privides 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 (5-9). Plus, each EFS bar gives you all five electrolytes (over 1,000mg/bar), in the levels endurance athletes require, to prevent cramping and dehydration (10). So you don't need to carry those extra 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 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 th appropriate changes were made to ensure the bar is exactly what endurance athletes require for racing and training. Nothing else even comes close.

"The taste and texture are great. I love this bar."
-Tom Jeffrey- 2006 US Pro Duathlon National Champion
"I like the EFS bars a lot! The texture is great and I had no trouble digesting it before and during my workouts. This has the potential to be a great during-competition bar."
-Michael Lovato 2006 Ironman Arizona Champion
"The EFS bar is a perfect combination of what the endurance athlete needs and wants for training and competition. This tasty bar is made from a high-quality mix of ingredients that includes simple carbohydrates for quick fuel and complex carbohydrates, protein, fat and electrolytes for long-lasting energy and recovery. Impressive that a bar that's so good for you could also have the ideal texture, taste, size and be easy to digest!"
