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

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 Goodbye muscle cramps A co-worker who uses Hammer Nutrition products suggested I try your Endurolytes after hearing I had muscle cramps after my first 1/2 Marathon. I bought a bottle along with other products and ran another 1/2 Marathon this past weekend. I took one tablet with some HEED prior to the start, another with more HEED and GEL at miles 7 and 10 and finished the race strong. Shaving six minutes off my first 1/2 Marathon and suffering NO muscle cramps after the race. Thank You Hanner Nutrition!

Rated 5 out of 5 by from Best electrolyte replacement! Have tried salt tabs, fizzy electrolyte tabs and other products - love these. They are flavorless, easy to digest and keep my electrolytes balanced so I can give a little more kick during long endurance workouts. Highly recommend!

Rated 5 out of 5 by from Great Product I have been using these for years for leg cramp prevention. Whether I have taken them during the day or not, I take 3 or 4 before bed to prevent leg cramps during the night. If I need to, I do it again during the night and like magic the cramps go away. They just seems to provide the correct combination of ingredients.

Rated 5 out of 5 by from Another Use! I recently had my colon removed and was dehydrated the entire time I had a temporary ostomy. Ordered these right before my reconnection surgery and felt better immediately! Wish I had found them sooner...so much better than electrolyte replacement drinks. As I'll always have a tendency towards dehydration I will continue to take them!

Rated 2 out of 5 by from Not impressed The endurolyte pills are hard to get down, don't think I'll be buying them again
Date published: 2015-04-07
Rated 5 out of 5 by from I don't even notice I am burning electrolytes. I use endurolytes throughout my day and whenever I am training. Carrying a water bottle during the day, I will add a scoop of powdered endurolytes to every 4th bottle. When working, I add a scoop of Endurolytes to 2 scoops Strawberry Heed and that powers me for at least 1.5 hours before I notice a bonk, at which point I have learned to mix another bottle before I hit that wall.

Rated 5 out of 5 by from Too good to be true? Every supplemental company promises miraculous results. It's just good marketing. For me, real results ranged from non-existent to barely moderate. So, it was with more than a "raised eyebrow' that I purchased my first product. This stuff works - period.

Rated 5 out of 5 by from Endurolytes are indispensible. As a bicycle commuter, endurance cyclist, and Century rider, I purchase about 6-10 bottles a year maybe more if it is hot out. I generally begin with Four (4) capsules then Two (2) capsules per hour on average.

Rated 5 out of 5 by from Great product so far! I recently started using Hammer products after reading about them in a running magazine. One of my first purchases was Endurolytes in the powder form. I am an ultra-endurance athlete and currently use it on my long training runs and also afterwards to rehydrate. So far I am pleased with the results. Much better than suger filled sport drinks. One thing I will point out is the taste. If you are mixing the powder in with plain water be advised, it has a very bland crushed-up pill taste to it.

Rated 4 out of 5 by from Works as Advertised My wife and I use Endurolytes for cycling. They prevent any cramping but essentially they serve to balance the body's electrolites. Furthermore my wife has suffered from cramping when sleeping. Endurolutes a coulple hours before bed time has served as a great preventative.

Rated 5 out of 5 by from Used these over the years I am a recreationally endurance participant, not a racer. I do the birkie, endurance mountain bike events, shorter Tri's, distance runs, etc. I can say with certainty I would have struggled to have finished a couple events without these things!

Rated 5 out of 5 by from Endurolytes before every race I use 2 - 4 endurolytes before every race. It the race goes longer than a couple of hours, I take more. Endurolytes will prevent cramping and keep your electrolytes in balance. They really work!

Rated 5 out of 5 by from Great Protection Against Muscle Cramps As a long time user of endurolytes capsules, I can attest that they protect my leg muscles from cramping and spasms after heavy exercising, both bicycling and personal training for hours. On long bike rides(over 30 miles), I take 1 capsule every 10 miles and several more after finishing along with my recovery drink. After an hour of intensive exercise at the gym, I also take 2 capsules along with plenty of liquid. This is the only product that consistently protects me from excruciating leg cramps. I swear by it!

Rated 5 out of 5 by from as always, Work Great I've been using these for several years now and have had almost zero muscle cramps during any long hard effort/ event.
Date published: 2014-11-11
Rated 3 out of 5 by from Average While the product makes an attempt to avoid the typical electrolyte "taste" it could benefit from flavoring to promote the continual drinking during the course of the day. It also takes a lot of effort to get the product to fully mix in solution.

Rated 5 out of 5 by from Amazing Product that WORKS!!! I used this product for the first time this hunting season and it works. My cramps are so bad I'm afraid to move at night when sleeping in my sleeping bag. If I have to get up, my hamstrings and quads cramp up at the same time. It feels like they're coming off my bone. I was able to double my distance with this product and FIZZ. No cramps during my hunts, at night or at home. AMAZING!!! I will be buying more.

Rated 5 out of 5 by from Life/leg savers. Just did the 42 mi on Timberline Trail around Mt Hood in a day. I had cramping/muscle issues on all the training runs previously and was scared for this run. Also I am vegan and use coconut water for an electrolyte while on the bicycle so for running there was no solution for electrolytes. I found and bought endurolytes at the last second and packed about 20. Fan-freakin-tastic, what else can i say? No cramping during or, even more suprisingly, after my run around Mt Hood. These are my new electrolyte staple for long runs. lightweight, vegan, highly effective and no stomach issues whatsoever. I was sweating and freezing at mile 30 of my run and if i would have had any leg cramping issues I would have been in BIG trouble. I am deeply grateful for this product. Hammer time!

Rated 5 out of 5 by from I am so happy I bought this product; I work out 4-6 days per week; I was getting leg and foot cramps at night; Endurolytes have solved the problem!
