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.

Great for long bike rides.I bought these because I'm doing Kona (Ironman) in a month and figured I could carry less capsules with me. I'll probably take one every 25 miles on the bike, because it will be pretty hot. The less stuff you have to carry the better. Plus, I will have to swallow less pills. I don't know if I will take any on the run, because hopefully when the sun goes down it won't be so hot.

DisappointedAs an avid cramper, I can't survive multi-hour MTB rides without my Endurolytes. Precisely why I was excited to see Endurolytes Extreme introduced, so I got them. My understanding was 1 capsule per hour, but during my recent 9 hour race (Hampshire 100), I needed more. So I up'ed to 1 each 1/2 hour...still cramped. I consumed a water bottle of Heed every hour, 2 full Camelbak's (70 oz.) of water, Hammer Gels, pickles, 6 PB&Js etc...still cramped...disappointed. Any suggestions?

So far so good!Out here in California it has been a very warm season and I was having trouble with the original endurolytes formula on long workouts. Endurolytes Extreme allows me to carry and take fewer pills and after 20 days is working great even in 100 degree plus temps.

WHY KEEP THIS STUFF TO YOURSELVES???I JUST STUMBLED ON THIS SIGHT LOOKING FOR SOMETHING TO HELP ME WITH MY CRAMPS. I GET CRAMPS IN MY LEGS, HANDS, BUT WORST OF ALL MY STOMACH. THOSE STOMACH CRAMPS ARE DEBILITATING AND EXTREMELY PAINFUL. FUNNY THING IS THAT I AM NOT AN ATHLETE....ACTUALLY FAR FROM IT. I HAVE HAD SIX BACK OPERATIONS FOUR OPERATIONS ON MY KNEES AND MOST RECENTLY ONE ON MY ANKLE. ITS JUST THAT I PERSPIRE PROFUSELY. I CAN BE OUT IN THE MIDDLE OF THE WINTER AND COME IN AFTER AN HOUR OR SO AND BE COMPLETELY SOAKED FROM HEAD TO TOE. I WAS A FORMER ENDUROLYTES USER BUT THEN YOU FOLKS CAME OUT WITH THE EXTREME AND IT HAS CUT MY DOSAGING DOWN TO A THIRD OF WHAT IT USED TO BE. THANK YOU FOR FINDING A WAY TO REFINE YOUR FORMULA. AND FOR GOODNESS SAKES, I SPREAD THE WORD OUT TO MY FRIENDS AND RELATIVES....MAYBE YOU FOLKS CAN FIND A WAY TO SPREAD THE WORD TO OTHER MARKETS. I AM A DIABETIC AND THIS STUFF IS A MIRACLE WORKER FOR ME. THANK YOU VERY MUCH!!!!!.

Endurolytes Extreme - Great StuffI'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.

Much more effecive than regular EndurolytesI 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).

Endurolytes ExtremeI 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 :)

Fantastic ProductI'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.

endurolytes extremeI 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

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.

Satisfied with Hammer Endurolytes ExtremeI 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.

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!
