Simple sugars in your sports drink will rapidly increase your blood sugar – so what’s wrong with that?
If you spike your blood sugar level then you will have lots of energy … for a little while, and then it will come crashing down. This doesn’t work so well for “endurance” athletes. Simple sugars can do just that, a little bit is okay but too much will quickly raise your blood sugar. If it could stay elevated life would be great, but unfortunately it can’t, and when and comes back down it drops (crashes) well below where it started. When this happens during athletic activity it is a dual edged sword.
First, your performance will drop as the blood sugar drops because your body is depending on that energy that is no longer available. More importantly, when your blood sugar spikes, your body will temporarily stop releasing insulin which plays a critical role in the energy conversion process. When insulin is released from the pancreas, it travels through the bloodstream to the body’s cells and tells the cell doors to open up to let the glucose in. Once inside, the cells convert glucose into energy to power your working muscles. If your insulin level drops then your body will no longer be able to as efficiently convert your muscle glycogen and glucose into usable energy … here comes the BONK!!!
The goal is to maintain a consistent blood sugar level without the spikes and crashes, and this is achieved by relying primarily on complex carbohydrates and low sugar levels, and that’s exactly what you get with e-Fuel!
"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." ... continue reading

"After having difficulty in races where my gastric system would 'lock up', I found that I simply couldn't handle gels and electrolyte pills frequently enough to support my needs. The calorie content and large amount of electrolytes in e-Fuel were a perfect balance for my training and racing needs. Because e-Fuel mixes fast and easy, it was easier for me to increase the concentration without worrying about trying to swallow a thick, clumpy drink.
At Ironman Wisconsin I raced with 2 bottles of 4x concentrated e-Fuel (800+ calories per bottle) on the bike as my primary nutrition. Using eFuel helped me surpass my goal and register a 13 hour finish time with no cramping or stomach problems. " ... continue reading

"I'm training for Ironman Florida and during the summer months here in Florida, long bike rides take me into some really hot and humid weather. I've been struggling for 6 weeks with cramping every time my ride hit 60-65 miles in length. I read about e-Fuel and after two rides of 80+ miles with no cramping, I'm a believer!" ... continue reading

"Been using your products for sometime now. Took a bit of a break from them, and decided to try some other brands. Using the competitors products, I was continually having leg cramps after 60 miles of riding. I switched back to e-Fuel, and no more cramps! Just finished a 110 mile 11000 feet climb this weekend! Couldn't have done it with out e-Fuel!" ... continue reading

"I have to tell you that this stuff is great. I haven't done any thing really long yet, only rides in the 50-70 mile range, but the effects are great. Makes the hills a little less painfull and the recovery is much better. It also mixes well and tastes as good or better than the competition.
I would like to really praise you on your excellent service. Your web site is perfect. I recieved prompt information regarding shipping and receiving of my shipment. You guys knew I got it before it did. That's kickin." ... continue reading

Jacksonville, North CarolinaSport: Triathlon, Running
"I have been using e-Fuel and e-Gel for about 6 years for training and racing in triathlons, running events and cycling events. It is the one product that has continuous energy supply without highs and lows. I have especially liked having all my nutrition needs on the bike premixed in my drink, so I don't have to fumble with gel packs on the bike. At age 47 I am amazed that I am still getting faster and going farther, and I attribute part of that to having a proper energy source and electrolytes during events." ... continue reading

"I try to bike pretty hard for an hour or longer each morning. By the time I'm finished my clothes stick to me and I feel both drained and exhilarated. I've tried sampling almost every sport drink I can buy in Portland and I think e-Fuel is the best. It's not overly sweet, seems to do a good job replenishing what I've lost, and doesn't make my blood sugar spike." ... continue reading

"I'm not one to typically use these type of supplements but the weather made me nervous about bonking. With e-Fuel, I never got that empty feeling. My energy was consistent throughout my workout. The taste was fine, not overpowering in any way. And I didn't experience any nausea or gi problems that often accompany these type of products." ... continue reading
Erie, PennsylvaniaSport: Running
"For 3 1/2 years I was searching for a hydrating-electrolyte drink for Ironman. I've tried Gatorade and that drink works fine on the bike, but it kills my stomach on the run. I've tried GU's drink, but it's tends to clump in the bottle. I've tried other drinks, but nothing seemed to work for me because the sugar content was high. A friend referred me to e-Fuel, I placed my first order and I was sold." ... continue reading

"Started using e-Fuel to find a way to increase energy output for the fast and aerobically challenging sport of indoor soccer. To my amazement it worked. As a goalkeeper I kept my e-Fuel bottle in the goal and took sips throughout my matches. The result was an incredible and exponential increase in reaction time and leaping ability. At the end of games the opposition are always in awe of my ability to make difficult and incredible saves. I will continue to use e-Fuel because it tastes great, dissolves rapidly and provides an exponential increase in energy for the demanding physical activitiy of indoor soccer." ... continue reading

"When my daughter started playing competive golf last summer, she fought blood sugar crashes that negatively impacted her performance. Sports drinks didn't have much staying power and she hates eating while playing. I found e-Fuel late last summer and she uses it every round now. She's had marathon rounds that I don't know if she could have finished if she didn't have the e-Fuel. Thanks for a great product." ... continue reading
