Product Detail & Benefits


Electrolyte replacement during exercise can vary as much as tenfold between two athletes. No other area of endurance nutrition or supplementation calls for such individualized dosing, and perhaps no other area of fueling can drop you out of the competition as quickly as electrolyte depletion or overdose. This is a critically important area where correct dosage is a must; you simply musn't consider getting electrolytes out of a premixed drink. The risk of too much fluid and too few electrolytes is high, which is not good for your stomach, muscles, or performance.

You want a product that allows effective electrolyte replenishment under any weather condition, any length of exercise, and any intensity of exercise. Endurolytes, unlike any other pill, tablet, or premixed drink, is that product. Also, don't make the mistake of thinking that electrolytes = sodium. Sodium alone cannot and will not effectively replenish electrolyte needs and may cause more problems than it resolves. With Endurolytes you're assured of getting all of the right minerals in exactly the right balance.

Endurolytes comes in convenient capsules or powder form. You can swallow the capsules hourly, or open them and mix your own amount into your water bottle, whichever is most convenient for you. When you don't feel like taking capsules, Endurolytes Powder is the answer. Nearly identical to the Endurolytes encapsulated formula, Endurolytes Powder comes "in bulk" with a scoop (one level scoop is equal to one Endurolytes capsule), allowing you to mix the powder directly into your water bottle. We've added 50 mg of the amino acid glycine, which helps neutralize the naturally salty, slightly bitter taste of the electrolytic minerals. There are 150 scoops (serving) per container.


Cramping is your body's final warning signal that you're on empty electrolyte-wise. When you've reached that point, the performance of many bodily systems has been severely compromised for some time. To keep your muscular, digestive, nervous, and cardiac systems firing on all cylinders, you need a consistent supply of all of the electrolytic minerals, not just sodium and potassium. Plus, in many instances, you require greater volumes of electrolytes than any sports drink or gel can provide. That is why Endurolytes fulfills such a crucial component of your fueling by supplying your body with a balanced, full-spectrum, rapidly assimilated electrolyte source, allowing you to meet your widely variable electrolyte needs with tremendous precision, hour after hour, no matter what the weather throws at you.

Extra Benefits:
Taking two or more Endurolytes before bed may help prevent night cramps and nighttime muscle twitching.


You must do your own trials with Endurolytes Powder dosing to help determine individual requirements. Expect amounts to vary greatly according to weather, event duration, and individual acclimatization.

The Heat Is On: Staying Cool in the Heat

The Heat Is On: Staying Cool in the Heat

With the summer's heat presently approaching, I have had several questions from the field on hydration, fuel selection, and electrolyte supplements for coping with thermic-induced DNF's, bonking, and cramping. Everyone is born with a unique, special one-of-a-kind biochemistry, which prevents even the best of scholars from professing a single correct formula for us all.

Rated 5 out of 5 by from Great results! I rely on Endurolytes for cramping control. I am a heavy sweater and taking this product makes ALL the difference in managing my electrolytes and keeping cramps away. Even hours later when I am done and resting I might have a cramp because I miss calculated, I pop1-2 capsules and have immediate relief!

Rated 5 out of 5 by from Skip the sports drink at the aid stations In training for my last marathon, I tried the sports drink that was going to be provided at the race. I have a pretty solid stomach, but the drink just never sat well. That's when I started researching other options and found Endurolytes. In reading some Hammer articles, I was even more convinced to skip the sports drink and just go with Endurolyte capsules for my electrolyte needs. Worked like a charm! I took a couple capsules before the race, and few more at the recommended times throughout the race with water, and never had an issue. In combination with Hammer Gels and Race Day Boost, I bettered my PR by almost 7 minutes, snagging my first sub-3 in 2:57! Thanks, Hammer!

Rated 2 out of 5 by from Does not mix well with water No matter how much shaking and mixing you do, this stuff will not dissolve in water. You just get chalky blobs that stick to the inside of the bottle or cup. Makes me wonder how much is actually getting into my system?

Rated 5 out of 5 by from Endurolytes I have used Endurolytes for years and never go on a long ride without them! Prior to using, I suffered from cramps. Once I started using them, NO MORE cramps. I am a believer.

Rated 5 out of 5 by from Endurolytes! A friend recommended endurolytes several years ago. We have been using them and recommending them since. We train reining horses, so we're out in the heat and South Florida sunshine year round. I also play tennis here year round and have not found a product that even comes close. Thank you, Hammer Nutrition. Lauri Ingram Ingram Performance Horses Loxahatchee, Fla.

Rated 5 out of 5 by from Cramp killer We've used these for years now. Prevents cramps and bonking just as advertised. We actually keep a bottle near our bed so if we get launched out of bed at night with a leg cramp after a long ride we can crush one under our tongue and (hopefully) get back to sleep quickly.

Rated 5 out of 5 by from Best Sodium/Electrolyte pill Not just sodium- also electrolytes. A must have for the hot weather. After a bad experience on a long ride in the heat last year, I'll never leave home without them when it's hot outside.

Rated 5 out of 5 by from Endurolytes to the rescue Was running out of gas after 8-9 holes on the golf course in the Florida heat. Studied hydration for a fix. Went to a running store and they recommended Endurolytes. I also use them for gym training and doing my yard. You may have another group of customers with amateur golfers. I like and will purchase Heed. Loved the Hammer bars - ordering them also. You sent me samples of Heed and the bars recently with my order. Thanks.

Rated 5 out of 5 by from Always get headaches I purchased these in packs. Reading the packaging it said it was for high temperature conditions. Problem with that - I'm a heavy sweater so it doesn't have to be very hot and I'm a puddle of sweat. These tabs work great! Keep my system balanced so I feel strong until the end of my ultra distances runs. No more headaches!

Rated 5 out of 5 by from No More Charley Horses! I used to have painful calf cramps almost every night, but have been using the Endurolytes power (a little in the morning and a little at night), I have not had cramps for at least four years!!!! I highly recommend this product.

Rated 4 out of 5 by from good results I've been using this for awhile and it has reduced the calf cramps I get at night.

Rated 5 out of 5 by from I love these things! These are wonderful. I didn't know what I was missing out on until I tried them. I would always just take water out on long runs or bikes. I usually don't like drinking anything but water, so these are great because I don't have to drink my electrolytes. I just pop a capsule in my mouth and go. And go and go and go..... I have recommended these to every distance runner I know and of those who listened, they thank me.

Rated 5 out of 5 by from Endurolytes.....on my "best" friend list!! On a very hot day last summer my leg cramped during a bicycle ride. A cycling friend let me try his Endurolytes and not only did the cramp go away but I felt an almost immediate relief of leg fatigue. Since that day I never cycle without a supply of Endurolytes with me and take 2 or more an hour on every ride. There is no question they improve my cycling ability. I also take them after a ride for recovery. I find Endurolytes are helpful when working out in the gym too. Love them!

Rated 5 out of 5 by from It helps me in the marathon... (by 14 minutes) A friend introduced me to these capsules after I kept experiencing dehydration in several marathons. Despite being "well trained," I still fell apart in the last 4 or 5 miles (in 2011 & '12). With the same amount of conditioning in 2013 (while using Hammer capsules), I was able to finally "cash in" my training and run two quality races (Boston & Marine Corps in 2:47 each). Before the capsules (& drinking more during races)... I was only able to pull off a 3:01. I hope to go even faster in 2014! I encourage folks to try them. I swallow one every 5 miles... maybe every 3 miles if it is really warm.

Rated 5 out of 5 by from Endurolytes I've been using Endurolytes for over two years with great results. On a run Endurolytes is an essential part of my regime. Honestly I really don't know how I would complete Ironman without Endurolytes. Love this stuff . . .

Rated 5 out of 5 by from Easy on the stomach, on long hot runs. Over the years I have tried everything to prevent cramping on Hot runs, Endurolytes is the only thing that has worked over and over again.

Rated 5 out of 5 by from Very useful in summer!! This products was recommended to me by a Hammer Rep before an 11 mile SUP race. In the past I always bonked out around mile 8 or 9. No issues at all and I raced totally relying on Hammer products, especially Endurolytes. No bonking and I held strong for 2nd place. If it is a hot day I am taking Endurolytes before any extreme activity.

Rated 5 out of 5 by from awesome stuff!! Love using these in endurance training..and in the heat especially...makes it all more comfortable with no cramping to deal with!!

Rated 5 out of 5 by from Very effective at restoring my electrolytes. Eliminated my cramping issues without the added sugars of some liquid replacement drinks.

Rated 5 out of 5 by from no more cramps! I used to wake up to the worst leg cramps ever. after determining that they were from my twice a day workouts, and heavy sweating, I tried endurolytes and now I swear by them! I take one after every workout, and if I am racing, I take one before, one during, and one after the event. I haven't had a cramp in over a year! I recommend them to all my patients who experience cramps, and for those that need to consume more water - I give them FIZZ tablets; they enjoy grape or lemon water while getting the electrolytes their body needs.

Rated 5 out of 5 by from Great product! I am a Letter Carrier for the United States Postal Service. I walk over 12 miles per day on my route 5 to 6 days a week. I used to suffer from severe leg camps at night. Since using this product and taking it per label directions throughout the day I have not had any relapses.
