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 No more headaches! I used to get headaches during &/or after exercise. After taking Endurolytes, I no longer have dehydration headaches. I also take it before bed to prevent leg cramps during the night. I highly recommend them.

Rated 5 out of 5 by from Great supplements! I took Endurolytes for approx 4 years to help with leg cramps (Charlie Horses). They helped greatly but I didn't realize how great they were until I decided to try a similar GNC product. Same minerals plus calcium. The Endurolyes did not elevate my potassium level. When the GNC product elevated my potassium greatly Dr said no more b/c of the GNC product, I noe had too high of a potassium level. Spasms began again so I went back to Endurolytes and once again spasms have stopped and potassium level at normal. I am 66 yrs old and Endurolytes has become once again part of my supplement regiment. Thanks, Hammer.

I'm a 66 year old Lacrosse goalie competing against all ages .... playing pretty much 40+ weeks a year plus tournaments 3 times a year.... I have bad knees and hips .... I probably overdue the dosage, but in the past 2 years taking the capsules I cant remember the last time I had cramps & retaining the fluids in my joints has helped me stay on the field longer and have less pain ......

Rated 5 out of 5 by from Simply electrolytes Endurolytes is excellent for managing electrolytes independently from food and hydration. I have to watch my blood sugar (type 2) and therefore have to watch my food and water carefully. Sweet sports drinks spike my blood sugar and speeds dehydration, quickly creating a downward cycle for endurance. Endurolytes let me supplement my electrolytes alone and eat lower glycemic foods and push hydration independently if I need to. Even on shorter rides, one before and one after makes a real difference. I am not an expert, but I know stuff.

Rated 5 out of 5 by from Better Fuel I started using Hammer endurolytes powder for traing and my first ever triathlon. I eat a very well rounded plant based diet and thought I could refuel myself with food alone. Upon trying the endurolytes powder I definitely noticed a difference in my hydration. The powder itself is real easy to use. I just do two scoops in my water bottle after a hard workout. I also take some in a water bottle or on my bike for longer distance training. The stuff works great for events too. I just did my first half ironman tri and it helped keep me hydrated the whole way to the finish. Love the stuff and I recommend it to all athletes who want a more specialized electrolyte delivery than a sugary, color dyed gator/power ade. One note I'd mention is the bottle says two scoops before activity and 1 per 50 lbs of body weight during. On regular training unless it's really hot or muggy I just skip it before and only do two scoops during exercise. That seems to do me the best and it'll make one tiny container last a LONG time. Great product! Thanks Hammer.

Rated 5 out of 5 by from Great product, perfectly portioned I chose Endurolytes powder because it is the only electrolyte supplement that is properly portioned according to the guidelines set forth in Nutrient Timing: The Future of Sports Nutrition. What's more, it doesn't contain unnecessary additives like sugar or artificial coloring, and Hammer fully discloses the ingredients rather than hiding poor quality or low levels of ingredients in "proprietary formulas" as so many companies do. Now that I'm a regular user I find that it is a high-quality product that gets the job done. I love that Hammer provides extensive documentation with the product covering not only what it is and how to use it but also addressing why it's beneficial. My only complaint is that the serving recommendations are too low per the aforementioned Nutrient Timing System guidelines, so I actually take double the recommended dose (i.e. 4 spoonfuls instead of 2) for great results.

Rated 4 out of 5 by from Sample packet of 4 caps. I have done many marathons and triathlons including a full Iron Man while using Endurolytes. I like the sample packets of four caps and will consume one packet per hour on a hot day (I am 190lbs). The advantage of the packets vrs the loose caps is that they will stay dry no matter how much I sweat or how hard it rains.

Rated 5 out of 5 by from Consistent I have used Endurolytes for three years now, and, with the other elements of my hydration and fuel planning ... have not cramped or had the fatigue I had on the bike before. I simply don't want to go into a road event without them.

Rated 5 out of 5 by from Works great I used to get exercise induce migraines about 2-3 hours after a hard workout in hot, humid weather, regardless of what I was drinking. Now, when the heat ramps up, I take Endurolytes, and the migraines are a thing of the past.

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.
