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 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!

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 Excellent supplements and customer service Fantastic 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.

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 TRULY OUTSTANDING Sometimes improvements to products really don't improve the product. Endurolyte Extremes are a definitive improvement on an already great product. I don't have to carry as many with me on a ride and they work great. I use them on hot and cold rides to stave-off depletion of critical nutrients and minerals, as well as minimize that hung-over feeling after riding 200 miles.
