More Information:

First Endurance EFS improves performance by supplying energy, amino acids and electrolytes for muscles to use when fuel stores begin to drop. EFS provides three different sources of carbohydrates for immediate energy and easy digestion during long and intense workouts, while the low osmolality of the EFS drink and ideal 7% carbohydrate solution provides superior fluid absorption. The first fuel to be fortified with clinically effective doses of the amino acids Glutamine, Leucine, Iso-Leucine and Valine, EFS improves glycogen re-synthesis and delays central (mental) fatigue through positive influence on the tryptophan/branched chain amino acid ratio.

Staff Review:

"We all know how important keeping hydrated is during physical exertion. I'm not one of those people who doesn't like to drink water. I love water! But when I'm trying to send my project route or I want to spend a full day climbing, I know there's value in grabbing a sports drink over just water. EFS is one of the best tasting and most effective drink mixes on the market. And for a real treat, fill your water bottle with a serving of EFS Tropical Punch and a serving of CRANK Forearm Fuel.
