First Endurance EFS-PRO redefines what's possible with high-carb fueling. This completely redesigned formula makes consuming more carbs per hour easier than ever while prioritizing stomach comfort. And with its clinically effective dose of electrolytes, EFS-PRO keeps you optimally fueled, hydrated and energized, even in the most demanding conditions.
The breakthrough technology in EFS-PRO allows you to fuel with more carbs and electrolytes without wreaking havoc on your stomach. From faster uptake to more efficient energy production, EFS-PRO's optimal balance of high-quality carbs is proven to increase athletic performance by supplying a steadier, more efficient source of fuel than conventional carbohydrates.
EFS-PRO is designed to be mixed at higher concentrations and still be absorbed quickly. It's easier on overworked GI tracts, and it boosts uptake of other critical performance nutrients like electrolytes – a force multiplier you'll notice the first time you use it.
The primary carbohydrate in EFS-PRO is a special, low-glycemic, easy-to-digest Cyclic Cluster Dextrin that gets absorbed incredibly fast without making you feel lethargic, bloated, or even worse.
Cyclic Cluster Dextrin (CCD) delivers a constant and stable release of energy. In addition, CCD preserves glycogen stores and stimulates fat oxidation for energy, so you'll be able to get the most out of every stride or pedal stroke, regardless of how deep you've already gone.
In addition to the revolutionary CCD, EFS-PRO also contains the ideal ratio of high-glycemic sugars to supercharge energy production. By gaming your biology, EFS-PRO effectively bypasses your body's inbuilt glucose limit, sneaking more carbs into the ATP cycle by way of a fructose-only backdoor – but keeping glucose saturation high enough to erase the shortcomings of fructose alone.
