Stomach Issues e-Fuel Hammer HEED
Sugar Substitutes None Xylitol
Flavors 100% Natural Natural

If you’re not familiar with xylitol, take a moment to do your own research on this sugar substitute. You will quickly find that xylitol is well documented to cause intestinal gas and diarrhea. That alone should be enough to concern any athlete, but it gets worse. According to WebMD there are concerns that long term use (more than 3 years) may cause tumors and they recommend that pregnant or breast-feeding women not use xylitol. Additional warning, even in small amounts xylitol is extremely toxic to dogs.

Just a little won’t hurt me, right?
Hammer does not disclose how much xylitol is in Hammer HEED, but if you look at the list of ingredients, xylitol is the second ingredient on the list. Further more, if you’re like most athletes, you use more than one bottle during each workout or competition. If you’re having any stomach discomfort with Hammer Heed, it may be being caused by the xylitol.

What about Stevia?
According to WebMD: Stevia and chemicals contained in stevia, including stevioside and rebaudioside A, can cause bloating or nausea. Other people have reported feelings of dizziness, muscle pain, and numbness. Using ingredients that cause stomach distress is the last thing that an athlete would want to deal with, so none of these ingredients are found in e-Fuel or e-Gel.

Electrolytes e-Fuel Hammer HEED
Sodium 150 mg 20 mg
Potassium 60 mg 13 mg

e-Fuel is designed to provide complete and balanced electrolyte replacement that is critical for proper hydration and to avoid muscle cramping and injuries. The sodium and potassium levels in e-Fuel are designed to meet the American College of Sports Medicine’s recommendation for electrolyte replacement during intense athletic activity.

Ironically, Hammer HEED stands for “Hydrating Energy Electrolyte Drink“, and yet the product has virtually no electrolytes. When using HEED, Hammer recommends using their electrolyte supplement product (Endurolytes). However, this is just one more thing to buy, one more thing to transport and figure how and how often to consume. With e-Fuel there is no need to use an electrolyte supplement, everything you need is already in the drink. A 24 ounce bottle of Hammer HEED contains only 60 mg of sodium when using the recommended 1 scoop per 16 oz (or 100mg when mixed at maximum recommended concentration). On the other hand, a 24 ounce bottle of e-Fuel Endurance Blend contains 450 mg of sodium for complete and balanced electrolyte replacement.

Citrates e-Fuel Hammer HEED

Potassium Citrate no
Citric Acid no

Patrick Binienda

"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." ...

"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. " ...

"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!" ...

"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!" ...

"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." ...

"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." ...

"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." ...
