Another Satisfied

"I have been using e-Gel and e-Fuel for a few years now and have found it superior to any other energy products that I have tried. Most other products give me a boost but then I end up crashing an hour or so after using them. I do not have that experience with your products. I seem to have a gentle letdown from the e-Gel. The e-Fuel is superior to any other product I have tried for refueling after a run, bike ride, or tough hike. My husband, an avid trail runner, agrees that your product is better than any others that he has tried. We found it to be "life saving" for our 10 year-old son when we were doing the trek into Everest Base Camp. We were at 16,000 feet and ran into a sudden blizzard. We had been hiking for about 3 hours and starting to get tired. The storm hit us with very little warning. We suited up in our cold weather clothing and still had about an hour hike to go. Our son started to slow down and would stop at any rock, wanting to sit down and sleep. We could not stop or carry him as we needed him to keep moving. We were able to get him to take an e-Gel and within 10 minutes there was a noticable difference in his energy. He started talking again and moving along without any trouble. We are so glad we had the e-Gel!" (read more)

 e-Fuel Endurance Blend

FRS is widely marketed to athletes, but with one of the highest levels of simple sugars, extremely low levels of complex carbohydrates and virtually no electrolytes it just doesn't stack up against the competition. e-Fuel's higher levels of complex cabs and lower sugars allows it to deliver significantly more energy (see discussion)

Maltodextrin is the preferred carbohydrate source for endurance athletes and as such it is the primary ingredient in e-Fuel as well as most other good products on the market. Cytomax is 55% simple sugars. The danger of high sugar content products such as Cytomax is that they can elevate your blood sugar level too far too fast which can lead to a sugar crash (also known as bonking). Higher sugar content also raises the osmolality of the product which can reduce energy delivery, delay fluid absorption and promote dehydration. 
e-Fuel is designed to provide complete and balanced electrolyte replacement that is critical for proper hydration and to avoid muscle cramping. 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.
The Citrates in e-Fuel assist in the carbohydrate to energy conversion process as well as reduce and slow the build-up of lactic acid in your muscles.
e-Fuel is one of the few sports drinks on the market that contains antioxidant vitamins C and E to help protect against tissue damage, reduce soreness and aid in the recovery process. 
Protein has to go through a digestive process which draws blood away from working muscles to the stomach and intestines. When you are competing in an aerobic activity you want as much blood as possible supplied to your muscles carrying fresh oxygen for the energy conversion process. Consequently, independent studies have found no benefit of protein in a sports drink. See the following article from the American College of Sports Medicine for a more complete discussion:

  Failure of Protein to Improve Performance when Added  to a Sports Drink

  Science Daily
  Protein-added Sports Drinks Don't Boost Performance
While caffeine may give a temporary mental boost, unfortunately it is a diuretic, meaning that it causes your kidneys to produce more urine - thus promoting dehydration. Proper hydration is critical to optimum performance, and in our opinion caffeine should not be incorporated into your sports nutrition program. Our recommendation has always been that if you feel that you NEED caffeine, then only use a caffeinated product (there are plenty on the market) near the end of your competition when you need the psychological boost the most and there is little time to cause dehydration. We strongly recommend against relying on a caffeinated product for the duration of the competition.
To our amazement, sucralose (also known as Splenda) and other artificial sweeteners have begun to show up in sports nutrition products. The name may sound harmless, but check out the Sucralose Toxicity Information Center  and the Potential Dangers of Sucralose by Dr. Joseph Mercola. The temptation by manufacturers to use sucralose is great, because high performance carbohydrates such as maltodextrin provide very little sweetness to the product. Thus, adding an artificial sweetener allows one to achieve a sweet product without using sucrose, high fructose corn syrup and other simple sugars. In our opinion, artificial sweeteners belong in diet soda, not sports nutrition products.
