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.

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

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).

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!

My new go-to Electrolyte supplementI've been searching for an electrolyte supplement and this is now my go-to supplement. Been a long time user of Nuun tablets, but was always left with a sugary aftertaste and on longer rides (80+ miles) would experience cramping regardless. I bought this just prior to riding a 105 mile event. The day of the ride it was HOT! Started of the ride at 85* and at the end of the ride it was 107*. Used only Endurolyte Extreme capsules and water for hydration. Never once had any concerns with feeling dehydrated and no signs of cramping. Overall very pleased with this product and will continue to use this along with all the other Hammer supplements and fuels that I've been using for year.

Excellent supplements and customer serviceFantastic company and products. 5 STARS. Last year I suffered heat exhaustion. My doctor, at the time, had no idea what was wrong with me. After $700.00 in lab work, he could only tell me that my potassium was low. So, I surfed the Internet and realized that I had severe heat exhaustion and needed some serious electrolytes. I purchased them, for the first time, from HAMMER and they were fantastic. Fast delivery and a telephone call inquiring how I liked my product.

Magic Pills!I never go on a ride without these. Fantastic product. I'll mountain bike for 4-5 hours cramp free so long as I stay on my hydration and my endurolytes. The exteme's are even better since they're stronger... you can carry less pills for the same effect. I weight 190 lbs and take 2 per hour unless it's super hot or a really tough ride, then I'll take more. If you're already cramping, you can chew these (taste terrible but anything beats cramping). I've handed them out to many riding friends... and since they make muscle cramps disappear we've gotten to calling them "Magic Pills." A great product from Hammer.

Economy of usageIt is so great that Hammer came up with a more concentrated formula for Endurolites. Now I can fit it into my feeding schedule easier, rather than having to keep track of three pills an hour, 20 minutes goes by fast when one is in the woods, I can take one extreme every hour and fit it within my Sustanined Energy feeding. Now I spend less time fiddling with containers and can keep concentrated on my running plan. Besides I am taking a third of the number of pills with me.
Thank you hammer

Solved my leg cramp problemI'm an avid recreational cyclist that likes to do centuries, but I struggled with painful hamstring cramps after an hour or two. Initially I tried regular Endurolytes, and they worked very well, but on multi-hour rides I forget to take the three capsules an hour I absolutely need. Endurolytes Extreme solved my problem. One capsule every hour on the hour and my legs continue to spin easily all day and are far less fatigued. I no longer struggle with leaden legs after mile 60 and finish strong. A true lifesaver for all my rides, especially in the heat and humidity of the gulf coast. I'm never without them!
