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.

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 5 out of 5 by from Just what you need! Hammer has really helped me dial in nutrition for my triathlons! I take these along with the fiz tabs in my water to get what I need for electrolytes on the bike and run.

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...

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 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 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!
