Product Details

Description:

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 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 2 out of 5 by from Disappointed As 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?

Rated 5 out of 5 by from Extremely satisfied I first bought these a few months prior to running the NOLA RNR marathon, and had great results. They really helped with my long runs, and coupled with Race caps...you can't go wrong.

Rated 5 out of 5 by from The Standard for Electrolytes I have been using Endurolytes Extreme for a few years now and just got back from a 3 day/325mi Bikepacking trip in consistent 80 degree heat. Once again, I can report that I was totally cramp-free during 24hrs of total bike time and maintained a high level of energy. It was interesting watching one of my riding mates who was relying on basically junk food and simple sugars tell me that during the heat of the day, he always was "no good"... I however felt great with my mix of Hammer Products including EE, Anti-fatigue Caps, HEED, Perpetuem, and Hammer Gel.

Rated 5 out of 5 by from Life saver! I have been having severe cramping/dehyrdration issues on my long runs (18+). Since I started using Endurolytes, I have not had any issues.

Rated 5 out of 5 by from Nothing else compares! This is the most complete recovery product I have ever used. After long events of softball or basketball officiating, you tend to lose a lot. Just follow the recommended doses and schedule and you will never go wrong! I have been taking this product for a month now and have yet to cramp up after an event. I will never use another product for electrolyte replacement. Simply Awesome!

Rated 5 out of 5 by from Athletes and Farmers I have shared my Endurolyte extreme with a farmer neighbor who is out all day in the heat. His chronic cramps have disappeared. Also shared with athlete friend who bicycles 30-50 miles regularly as well as participates in multiple high energy activities. After a bout with heat exhaustion on last ride, she is a convert too.

Rated 5 out of 5 by from Works Great! I bought these a couple months ago to see if they worked and they do. I take 1 every hour during by ride and they help to keep the leg cramps away. I carry them with me every ride. I also use them after my ride, now my leg muscles do not twitch and cramp at night while I'm trying to sleep. Great job Hammer!

Rated 5 out of 5 by from Ride saver Endurolytes Supreme is by far the best suplent to on the market, hands down. I don't ride without them, keep them by my bedside after hard races just in case a cramp comes on in the middle of the night. They are a "ride saver!"

Rated 5 out of 5 by from So easy! This is the easiest electrolyte solution for training in hot and humid weather. Just pop one an hour and you're good- no extra bloating from oz after oz of fluids, but no crash and bonk from imbalances either. Love them.

Rated 5 out of 5 by from Wouldn't ride long distance without them! I was counting on Endurolytes Extreme and Anti-Fatigue Caps as well as Hammer bars to get me through my last Iron Man race earlier this year and as usual Hammer products did not disappoint. It was a tough day in the wind cycling and I was afraid of bonking so I back off a bit, however I realized at the end, that the Hammer products did their job so well I could have pushed myself a little harder. Thanks Hammer!

Rated 1 out of 5 by from Left me bloated and dehydrated Forgive me, HAMMER; I usually have nothing but good things to say about your products, but... History: Took 1 EE prior to 6 hour/100 mile cycling race (82ºF), then 1 more EE at the midpoint. Stayed hydrated and kept carbs and calories (HEED+Gels) in check. Seemed to sweat more than usual with EE's, and the last hour I felt more "spent" than usual. Post-Race: Did my normal Recoverite, a little pasta, and plenty of water. Hit the sack. The real problem was the next day; bloated, and unusually dehydrated. Woke up in the middle of the night THIRSTY. Gained a bunch of water weight that after 2 days is finally dissipating. Never had this issue prior to using EE; ride plenty of centuries on the weekends for fun without EE in the past and never had any bloating, dehydration, or next-day thirst issues. I absolutely do sweat without them, and thought EE's might complement the electrolyte loss. I originally bought EE's because I had a slight cramping issue on a previous race thinking they might help, but I think the unintended side-effects are worse than dealing with a little cramping (which, in my case, is most likely from overuse, and not necessarily electrolyte loss). The ONLY thing that changed was the addition of EE's to my fuel; everything else remains constant. This is the third time I've tried EE's, and suffered the same side-effects post-ride. HAMMER does their homework, but please know that every HAMMER product does not necessarily work for every athlete. You must make your own choices based on using them and discovering how well they work for YOUR unique athletic situation. I think I'll stick to HEED (don't like Perpetuem) and Gels. Sorry HAMMER!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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!!!!!.

Rated 5 out of 5 by from Don't sweat it when you sweat it! I have found that this is the difference between fun long rides and awful long rides. I have handed them to random folks stopped on the side of the trail. They took them, and the magic happens. This is simple chemistry: without these minerals, the neuromuscular system goes completely whack (a technical term).

Rated 5 out of 5 by from Incredible results! Recently purchased to support my electrolyte needs while performing demanding manual labor activities outside during 90+ degree weather. Work like a charm; no cramping, no bonking, no nausea. Taking the minimum suggested dose, too! Works excellently along with HEED and Hammer Gel.

Rated 4 out of 5 by from 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.

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 5 out of 5 by from Perfect for the heat Used this product in New York to test out prior to a 6 hour race in the heat and elevation in Utah - perfect combination to get me through the day and not cramp like so many other competitors.

Rated 5 out of 5 by from Great product Used this on a 50 mile trail run that I wasn't fully prepared for. Supplemented every few hours with four Endurolyte Extremes and lots of water and food. Really helped me finish the race.

Rated 5 out of 5 by from Race day necessity! We use this product throughout the competitive day. We will dance at least 38 heats at a competition and this product helps with hydration, fatigue. We call it our anti cramping device!

Rated 5 out of 5 by from No more leg cramps I have used Endurolytes for many years but did a trip where temps were going to be over the top. Switched to the Extreme for added insurance and they did the trick. No leg cramps...
