Another Satisfied
Customer:

"I just finished a multi-day event where I ran through the Benton MacKay Trail, start to finish, over 287 miles - fueling almost exclusively on e-Fuel. Each day consisted of an average of 35 miles across some of the toughest mountain trails in the Eastern US. e-Fuel carried me through 9 days with little other nutrition except dinner meals. I have always suffered from over/under hydration using other fuels - e-Fuel is the most complete and efficient fuel I have used. My mountain adventure was a great success largely due to e-Fuel."

Osmolality is the measure of concentration of a fluid. Depending on the concentration, an ingested fluid can be either hypertonic (more concentrated than your body fluids), isotonic (equal in concentration to your body fluids) or hypotonic (less concentrated than your body fluids).


Hypotonic solutions such as water do a good job of hydrating your body. Unfortunately they bring very little, if any, energy and electrolyte replacement benefits into the cellular system.

Isotonic solutions can also provide rapid hydration, and they have the potential advantage of bringing significant energy and electrolyte replacement benefits into the cellular system. e-Fuel is an Isotonic solution.

Hypertonic solutions are absorbed at a slower rate than hypotonic or isotonic solutions, thus delaying the desired hydration and energy benefits. During training or competition, hypertonic solutions can also have a dehydrating effect as your body draws on it's available fluids to dilute the solution down to an isotonic level. 



OIsmolality is only one part of the equation. It is also important to look at the carbohydrate sources used in your sports drink. Simple sugars that are often found in sports drinks have the effect of raising the osmolality more rapidly compared to equal amounts of complex carbohydrates. For this reason, drinks made with maltodextrin (a complex carbohydrate) can provide significantly more energy benefits in an isotonic state.

e-Fuel derives 71% of it's carbohydrate energy from complex carbohydrates (maltodextrin), significantly more than the leading sports drinks. Because of this, e-Fuel provides up to 75% more energy than other isotonic sports drinks containing glucose, sucrose and dextrose. Equally as important is the rate at which energy is delivered to your body,  and e-Fuel's sustained energy formula is designed to avoid blood sugar fluctuations that lead to the dreaded "bonk".
