1ST Endurance EFS 25 Serving Drink Mix

EFS drinks provide everything you need to maximize endurance and performance during your ride. Clinical research shows that endurance athletes require a higher level of electrolytes to prevent dehydration and cramping. Therefore, EFS drinks now contain 1,160mg of 5 electrolytes per serving, which is more than any other electrolyte drink on the market. First Endurance only uses the best. The AjiPure amino acid is the purest, most- bio-available source of free- form amino acids with a purity level of 99-100%, which results in a more complete and faster absorption. Unlike many other sports drinks, First Endurance utilized two unique sources of calcium and magnisum, DiCalcium Malate and Dimagnesium Malate. Lastly, unlike the older formula, the new EFS drinks now contain 700mg of Malic Acid which stimulates oxygen consumption by increasing mitochondrial uptake.

      EFS is a superior product to other electrolyte drinks. During hot competitions during the warmer months on the bike I have noticed profound increases in endurance. I attribute many of my wins and top places to the use of EFS. Easy to use and tastes great. Craig VanValkenburg Auburn, Al

        Comments about First Endurance 1ST Endurance EFS 25 Serving Drink Mix:

        If you normally don't like the taste of orange, you may like this as it has very little taste. I've tried grape, citrus, and orange. So far the grape flavor tastes the best.

          Cramps be Gone

              This product works as advertised. I used Cytomax previously and still had issues with leg cramps after training rides. This product alleviated that problem. The grape flavor does have a slight salty after taste. I didn't mind the saltiness, but those who prefer a sweet, sugary taste (I don't) might not like the taste. A bit pricy though.

              Best Stuff for long rides and cramping

              By Brad the biker

              from SLC, Utah

              Verified Reviewer

              Comments about First Endurance 1ST Endurance EFS 25 Serving Drink Mix:

              I've used Heed, Scratch Labs, and a few others. Although some work better than others this by far works the best for cramping and salt replenishment on the long endurance rides. Doesn't taste that great until your body needs it, then its like candy to a kid.
