Hammer Nutrition Endurolytes - 120 Capsules Reviews:


Maintain Electrolyte Balance Easily

I use Endurolytes whenever I go on very long rides and whenever it's hot enough that I worry about excessive sweating throwing off my electrolyte balance. They're great because they're easy to take (just swallow the caplets or, if you prefer, open the caplets and add them to your drink) and pretty easy to carry with you during exercise. You just take a couple of caplets every hour or two, depending on conditions. You can even get a little caplet dispenser (which makes your life much easier if you're doing extended training or racing) from Hammer Nutrition if you want.

Anecdotally, I had terrible problems with cramping -- especially in road races over 2 hours on hot days -- before I started using these. Now, I get cramps only very rarely. So they've really helped me.

Finally a product that eliminates cramps

I have had problems with leg cramps during and after hard exercise for years. I tried lots of water, then lots of salt with my water. My doctor said to try magnesium, but Mg is difficult to find in foods. I ate lots of nuts to no avail. Finally, I tried taking the full dose of Endurolytes on a backcountry ski that I was sure would put me in agony that evening - no cramps. Now, I take a couple of capsules just before, and 4 to 6 capsules during a day of hard skiing, hiking, or biking where I loose 3 to 4 liters of water. I usually eat a little candy with it because sugar may be important for absorption from the gut.

Regulate your electrolytes

Endurolytes are the perfect way to regulate your electrolyte needs and customize according to the conditions of your event. Encased in capsules, Hammer's electrolyte blend, goes down easy and is tasteless, but provides the right dose of "salts" to keep you going in even the hottest conditions and avoid painful cramps. Using Endurolytes is a convenient way to know exactly how much electrolytes you are consuming and is a great product to supplement the other Hammer drinks regardless of the type of event you are competing. Get an edge on the "heat" of the competition by using Endurolytes!

Stop Cramping!

Endurolytes are perfect if you are planning to take an on endeavor where you think cramping might become a factor. Perhaps a long bike ride or hike where you are worried about uncomfortable cramping. I find that Endurolytes are very effective in keeping those nasty knots out of my legs on long rides or during hot days when I might not be able to consume enough fluids. If you need to hedge against cramping during an activity, these are the perfect product you need!

A "Must Have" for every athlete!

Endurolytes really are a "must have" product. Keeping electrolytes in balance is absolutely necessary for top performance. I use these daily to keep things in check during training, and am religious about using every hour during running, biking and adventure racing events. I would not think of doing a race without them! Anytime I feel the beginning of a muscle cramp I KNOW I have forgotten to take Endurolytes (or not enough) and pop one in my mouth for almost immediate relief!

Great for long distance backpackers!

Great product! My wife and I tested these on a 2 week trip of the JMT. We were tired of the mixes we used in our bladders or bottles, it was a waste of time to clean up and you can never get the taste out. We popped 1 pill every 2 hours. If we were sweating a lot, we popped 2. Worked great! I honestly feel it was one of the factors that helped us push 15+ miles per day!

Impossible Without Endurolytes!

I use this product with other Hammer products continuously during endurance training and events from 2-6 hours. I train and compete at high altitudes and often in the heat, and Endurolytes is the best way to replace depleted electrolytes and prevent exhaustion or worse. The product can be taken with other fuels without causing digestion issues. It is indispensable and I wouldn't consider training or competing without a sufficient supply to see me through the event.

Must have training/race item

Iv'e used endurolytes for every Ironman I have done. Without these I would have never been able to do as well as I have in all my races. They work great with your sports drink and really prevent the cramping and muscle fatique that accompanies endurance training. I have actually had people come up to me during races and ask if I have any extra endurolyte's. A must have for any athlete

I wish I knew about these before

Ditto what everyone else said about cramps. I wish I had know about these much earlier in life although I am not sure this product has existed for very long. I have had serious problems with cramps and muscle spasms while involved in any kind of lenthy endurance activity. This problem has been eliminated and I feel better overall during such events including backpacking and cycling.

I was introduced to Hammer Nutrition Endurolytes by a friend on a 12.8 mile canyoneering in Zion in 2010. When I returned to Montana I knew I had to get some and was very happy to learn that they were made by a Montana company. They completely prevented leg cramps which has always been a problem for me after strenuous exercising, hiking and hunting.
