Endurolytes Extreme Capsules


All the benefits of our best-selling Endurolyte Extreme capsules are now offered in an easy-to-mix powder. This all-new formula dissolves quickly and completely, with a subtle, natural watermelon flavor. Consume in water alone or add it to your liquid fuels according to your unique dosing needs. The mild flavor makes it easy to drink all day, while the lack of residue makes it perfect for hydration packs and bottles of any form.

With three times the sodium chloride and potassium, and a softer flavor profile than Fizz, this is the perfect solution for multihour bottles of fuel, those who dislike consuming capsules, and those whose electrolyte needs are high. Regardless of the conditions, duration, or intensity of your activities, Endurolytes Extreme Powder has you covered.

Mix 1 scoop in 16-28 ounces (approx 475-828 ml) of water and consume hourly during exercise. Extreme conditions may warrant higher dosage.

Ingredient Breakdown:

Full-Spectrum Electrolyte Profile – This complete profile contains the following minerals:

Sodium – Sourced from salt, which is comprised of 40% sodium.

Chloride – Sourced from salt, which is comprised of 60% chloride

Calcium Lactate Gluconate – A compound containing calcium, lactic acid and gluconic acid, calcium lactate gluconate is used for its neutral taste and excellent solubility.

Magnesium Lactate Gluconate – A compound containing magnesium, lactic acid and gluconic acid, mangesium lactate gluconate is used for its neutral taste and excellent solubility.

Potassium Citrate – A compound containing potassium and citric acid, potassium citrate is an excellent, easily dissolvable source of potassium.

Manganese – This trace mineral is necessary for optimal muscle cell enzyme reactions and for the conversion of fatty acids and protein into energy.

Silicon Dioxide – Necessary for anti-caking, Endurolytes Extreme Powder contains a premium trademarked version called Flo-Gard™ SP, which contains no calories, GMOs, or allergens.

Monk Fruit – A natural, calorie-free sweetener that does not affect insulin production. The sweetness from monk fruit is not due to natural sugars like most fruits, but instead from its naturally occurring antioxidants called mogrosides.

Can't believe so little does so much

I got my shipment two days ago and came back to the website to check that the correct amount was only 1 scoop! I used this product on a 2 hour Endurance ride, then on a VO2 Max workout. I couldn't believe how well this worked. Very subtle watermelon flavor continuing Hammer tradition of taste not be...

Not For Me

After reading the reviews about the watermelon flavor being very subtle and loving the fizz taste, I thought I was going to love this stuff. Maybe I'm using it wrong, but I don't like the flavor, tastes like salty watermelon. I had to force the drink down. Then I tried mixing it with Perpetuem, and ...

After 15 years of the bike, I'm back in the saddle and training for the spring. As were the products when it was E-Caps, I'm really happy with the results—endurolytes powder is allowing me to push through jam-packed weight/plyo/HIIT sessions smoothly.

Website says 1 scoop per 16-28 oz and the package says 2 scoops per water bottle. Water bottles are 16+ ozs, so which one is it? Thanks in advance.

Asked by Platypus
Verified Reply - SteveThe verbiage on the website states: "Mix 1 scoop in 16-28 ounces (approx 475-828 ml) of water and consume hourly during exercise. Extreme conditions may warrant higher dosage." The text on the labels reads: "Mix 1 scoop per hour in water bottle during prolonged exercise. Extreme conditions may warrant higher dosages." 16-28 ounces of fluid per hour is our hydration recommendation, and as you alluded to in your question, water bottles usually start at a 16-ounce size. Not sure if you may have an older label where it suggests 2 scoops per water bottle, but nonetheless, we recommend starting with 1 scoop of Endurolytes Extreme Powder hourly.

Is the corn used for the maltodextrin non GMO?

Asked by Janell
Verified Reply - SteveI estimate that the maltodextrin we currently use in our products is obtained from 50% GMO-free corn and 50% conventionally grown corn. Here’s the deal, though: By the time it goes from original material (corn) to end product (maltodextrin), it has been so heavily processed that the DNA of the corn is degraded and all that is left is the carbohydrate component, which of course is the maltodextrin. Batches from the manufacturer we use go through a test called PCR (polymerase chain reaction), and in every case no GMO residues, pesticides, or herbicides—even in parts per billion (ppb)—are ever detected. It is a VERY clean finished product. That, along with the fact that there is only 1 gram of maltodextrin in every scoop of Endurolytes Extreme Powder, should eliminate concerns. With all that said, hopefully, more-readily available and reasonably priced 100% GMO-free corn will become more of a reality. We’re definitely keeping our eye on that because, even though the maltodextrin in our products is essentially GMO-free no matter what corn we use, we’d rather use 100% GMO-free corn because it would benefit crop growing in general (i.e. more farmers growing GMO-free corn).

Is this product gluten free? I see that it contains maltodextrin and I'm wondering if it is derived from wheat or from corn...

Asked by Janie
Verified Reply - SteveEndurolytes Extreme Powder is gluten-free. In each scoop there is 1 gram of corn-derived maltodextrin.

The instructions above say "Mix 1 scoop per hour in water bottle..." What size water bottle are we talking about?

Asked by BrianB
Verified Reply - SteveIn general, most athletes, under most conditions, will satisfy hydration needs with a fluid intake in the range of 20-25-ounces/hour - roughly the equivalent of a standard size small or large water bottle. Lighter athletes and/or athletes exercising in cool weather conditions may only require an intake of 16-18 ounces/hour. Larger athletes and/or athletes exercising under very hot and humid conditions are the ones that can consider a fluid intake in the range of 28 ounces/hour, perhaps up to 30 ounces/hour in extreme conditions.

Is the flavor mild enough that when mixed with the diluted juices I use that it doesn't overpower or significantly change their flavor or the perceived taste intensity of the drink? Right now depending on the ride conditions, a 40/60 to 60/40 juice/water with salt or lite salt added for additional electrolyte. However I've been thinking maybe I should broaden the types of electrolytes in my mix. Not sure if there is any science to say one is better, with the exception I can lower the sodium somewhat while increasing others. Thoughts on the flavor mixing or suggest another product for my water bottle mix?

Asked by inquisitive
Verified Reply - Hammer SteveThe natural watermelon flavor in Endurolytes Extreme Powder is VERY subtle and mild, so it shouldn't alter the taste of flavored fuels very much at all, if at all.

Can I mix it with other products? Say, mix a scoop with Perpetuem in the same bottle?

Asked by DLT
Verified Reply - Hammer SteveAbsolutely! The natural watermelon flavor in Endurolytes Extreme Powder is VERY subtle, so it shouldn't alter the taste of Perpetuem or other Hammer Nutrition fuels very much at all, if at all.

Is it carbonated? Love the Fizz product but tends to cause small geysers with my water bottles.

Asked by JLS
Verified Reply - Hammer SteveUnlike Endurolyte Fizz, which is an effervescent tablet, Endurolytes Extreme Powder does not have any carbonation effects when mixed in water. The mineral forms in the formula were specifically selected because they are not only well absorbed, they dissolve extremely well when mixed in solution.

How does the powder compare with the Endurolytes capsules? If I normally take 2 capsules every hour during summer ultra marathon paddling, what would be the powder dosage?

Asked by Happi
Verified Reply - Hammer SteveEndurolytes Extreme--both in capsule and powder--contains three times the sodium chloride (salt) and potassium content as the original Endurolytes capsules. The other electrolytic mineral components in these products are fairly similar in terms of amounts. That said, 1 scoop of Endurolytes Extreme Powder (ELXP) is going to be identical to 1 Endurolytes Extreme (ELX) capsule, and approximately 1/3 of a regular/original Endurolytes (EL) capsule. If you're typically taking 2 regular Endurolytes (EL) capsules an hour, taking 2/3 scoop of Endurolytes Extreme Powder (ELXP) will be similar in terms of dosing.

Endurolytes Extreme Powder vs Fizz. I use Fizz, how does the power compair? I use one Fizz per 16.5 oz of water how much power would I use to get the same strength ?

Asked by David K
Verified Reply - Hammer SteveIt's not really possible to make an apples-to-apples comparison between the two because the formulations are different and contain differing amounts of mineral compounds to arrive at "X" of the elemental amount of each mineral. Some observations: 1) MORE SALT IN ENDUROLYTES EXTREME POWDER -- One Endurolytes Fizz tablet contains 260 mg of salt (200 mg of sodium; 60 mg of chloride). One scoop of Endurolytes Extreme Powder contains 315 mg of salt (125 mg of sodium; 190 mg of chloride) 2) MORE CALCIUM AND MAGNESIUM IN ENDUROLYTES FIZZ -- The primary focus of Endurolytes Extreme Powder is on the salt (sodium chloride) and potassium content, which is why there is not as much volume of calcium and magnesium in the product as compared to Endurolytes Fizz. CONCLUSION: While the two products are different in terms of the type of mineral compounds used and the elemental content of each mineral, 1 tablet of Endurolytes Fizz is fairly close--especially in salt and potassium content--to 1 scoop of Endurolytes Extreme Powder. ENDUROLYTES FIZZ (1 tablet) Vitamin B6 (as Pyridoxine Hydrochloride) – 13mg Calcium (as Calcium Carbonate, Calcium Chloride) – 100mg Magnesium (as Magnesium Carbonate, Magnesium Oxide) – 50mg Manganese (as Manganese Gluconate) – 3mg Chloride (as Calcium Chloride) – 60mg Sodium (as Sodium Bicarbonate) – 200mg Potassium (as Potassium Bicarbonate) – 100mg ENDUROLYTES EXTREME POWDER (1 scoop) Sodium (as Sodium Chloride) – 125mg Chloride (as Sodium Chloride) – 190mg Calcium (as Calcium Lactate Gluconate) – 40mg Magnesium (as Magnesium Lactate Gluconate) – 20mg Potassium (as Potassium Citrate) – 75mg Manganese (as Manganese Gluconate) – 0.5mg

Is there an acceptable range of time when mixing in advance? For instance, can I mix 24 hours prior to consumption?

Asked by Rich
Verified Reply - Hammer SteveAfter a 24-hour period there may be some loss in the taste of the product (which is very subtle to begin with), but there should be no loss of potency or efficacy with the mineral content in Endurolytes Extreme Powder. Also, although the mineral content dissolves extremely well, after 24 hours there may (key word "may") be a small amount of settling of the mineral content at the bottom of a water bottle. If that occurs, a good shake will remix everything nicely.
