Product Details


Designed for the harshest conditions, as well as other variables that require higher amounts of specific electrolytic minerals, Endurolytes Extreme has you covered! With each capsule containing 300 mg of sodium chloride (salt) and 75 mg of potassium per capsule—three times more than the original Endurolytes formula, yet still in a balanced 4:1 ratio—Endurolytes Extreme is guaranteed to resolve even the toughest electrolyte replenishment challenges, especially:

  • During unusually hot-weather events
  • If you're not acclimated to the weather conditions
  • If you consume a high-sodium diet
  • If you are "physiologically predisposed" to cramping (e.g., if you have extremely high sweat rates)
  • During early season training, a time when fitness levels are low, resulting in higher mineral losses

If one of more of these categories describes you or your circumstances, Endurolytes Extreme is the product you need.

Product Reviews

Rated 5 out of 5 by from Endurolyte Extreme - did what they said I train in Texas where temps get extreme & these helped during those workouts where temps are limiters to training performance.

Rated 5 out of 5 by from Endurolytes Extreme - Great Stuff I've used regular E-Caps for years. Now, the Extreme version is even better--especially for running in the summer heat of the Arizona desert.

Rated 5 out of 5 by from Much more effecive than regular Endurolytes I had been using regular Endurolytes with okay results. I purchased the Extreme version about a month ago and am using it to train for an Ironman. I have had two long workouts in very hot and humid conditions now where I've used this product and have had no issues with cramping or feeling bad. It wasn't until I was reading on Facebook and seeing my friend's descriptions on how miserable their workouts were (because of the heat and humidity) that I realized how hot and humid the day was and how much the Extreme Endurorlytes were helping me. GREAT product and definitely worth the extra cost over regular Endurolytes (you also don't have to use as many capsules either to get the desired result).

Rated 5 out of 5 by from Endurolytes Extreme I usually suffer from cramps during distance cycling events. I used Endurolytes Extreme with Endurolytes powder + Heed for the 2014 Lumberjack 100 and didn't have a single cramp the entire race. Climbed every hill on the bike :)

Rated 5 out of 5 by from Fantastic Product I've only had them for a little while, but I love the Endurolytes Extreme. I tried the Endurolytes before, and I am a big fan! Now, it's time to go harder, and I'm trusting Endurolytes Extreme to help me get to the next level.

Rated 3 out of 5 by from endurolytes extreme I purchased these without looking at the label first and actually prefer more potassium than sodium as it works better and faster for me with my leg muscle cramping during rides. I will go back to the regular endurolytes and hopefully you will always make these. I am not real happy with these extremes and still have 3 unopened bottles and wish I could return them and replace with the regular endurolytes. let me know if I am able to do so as I am nor pleased with the results for me and don't really like that there is more sodium. I think the regular endurolytes are a better balance of sodium, potassium and magnesium. Joel Kwiatkowski

Rated 5 out of 5 by from Great for Long Runs! Training for a 100 miles race and have completed several over 40 miles runs with no cramping. take 1 pill every 1 to 1 1/2 seems to be working for me.

Rated 5 out of 5 by from Satisfied with Hammer Endurolytes Extreme I used Enduruolytes Extreme at the Oklahoma City Marathon and although the temperature was in the 70s, due to almost 2 hours of delay in the race, I did not experience any cramps. I've recommended this product to all my running friends.

Rated 5 out of 5 by from Great product for "ultra" training! I've been using endurolytes for years for all my endurance training- always had tremendous results. My only gripe was that in my long training runs (and races) of 3 hours and longer I averaged 3 endurolyes pills an hour to take care of my electrolytic needs. Not a huge gripe, but hammer read my mind with this product- the same amount of sodium and chloride, still the full range of the "other" electrolytes all in 1 pill. Used them on a long (4.5 hour) run this weekend, and they performed as expected- amazing!
