Product Review -First Endurance EFS Sports Drink

Sports drinks are an interesting breed. Once upon a time I used to think Gatorade was the stuff. I was sweet and came in cool flavors and well Michael Jordan drank it so it must be good. It was there on the course of a few races so I used it. But it really didn't do anything for me other than quench my thirst, stain my clothes and goo up my derailer on the bike (LBS "fixed my derailer" by cleaning the gatorage residue stuck to it.)

Since I switched to First Endurance Products I have found a truely superior product that actually does something for me in addition to quench my thirst. EFS Sports Drink-Electrolyte Fuel System is a very unique product that works great for me. First thing you notice is the electrolytes. EFS contains 1160 mg per 12 oz serving of Na+, K+, Mg+, Ca+, and Cl-. Compare that to 163 mg for Cytomax, 216 for Gu Electrolyte Brew, and 435 for Gatorade Endurance and it is head and shoulders above its peers. So what does that mean? Well it means when you are standing around before a workout it has a salty aftertaste. But only you start working up a good sweat, you don't notice that at all and your body in replenishing the electrolytes it is sweating out. EFS has been proven to prevent cramping and dehydration even on the hottest and most humid days. With EFS you also don't need to take electrolyte tabs.

But EFS it more than that. At 96 cals/ 12 oz it is a great source of calories on the bike. It can be mixed at double strentgh for more calories. Another thing that sets EFS apart is the blend of amino acids. EFS uses Ajipure amino acids which are 99-100% pure which results in better absorption. The mix of Carbs and Protein fuel the body with everything to needs during a long workout. EFS also used Malic Acid (700 mg/ 12 oz serving)which stimulates oxygen consumption by increasing mitochondrial uptake, improving mitochondrial respiration and increasing energy production (I sure sound smart reading the bottle-Eh).

What does that mean to me? It means that I can feel a boost after I take a swig of EFS on a hot day. Since I have used EFS, I have yet to have the calf cramps that would plague me on run leg of those hot humid PA-NJ-MD summer races. I don't bonk, and unlike the sweet taste of gatorade, after 10 or so hours of EFS during an Iron Distance race, I can still stand the thought of drinking it. Since I switched I have PR at the Iron Distance on a hot day at Rev3 Cedar Point and EFS paid dividends my holding the cramps at bay and allowing me to run a consistant marathon.

Bottom Line: EFS sports drink has proven its worth to me in workouts and races and I would highly reccommend it. Comes in several flavors including Grape, Fruit Punch, and Lemon-Lime (I like grape best.) Give it a try, your body will thank you for it!


  1. Great post. I can't wait to put my EFS to the test this summer. I thought Cedar point was cool but did heat up in the afternoon. You need to come race in the deep of summer. Talk about hot as haties

  2. I love grape EFS. It rocks. I have tried the other flavors, but Grape is definitely the best.

  3. Spectacular review. I love the Lemon/Lime flavor. It's tart!
