There has been a debate going on in the sports nutrition industry for the past 25+ years. The opposing sides consist of the high sodium advocates and the low-sodium advocates. Until 1996, high sodium advocates had the stage all to themselves with an abundance of sweat studies to point to as evidence to support their side. Leading the low sodium side, we had a lot of anecdotal information from athletes, but not much more. That’s all changed, and I’m happy to share this exciting new data today. You significantly improve your ability to tolerate heat stress by lowering dietary sodium intake!
With the introduction of Hammer Nutrition’s Endurolytes® formula in 1997, a full-spectrum, all-chelated, proportionately balanced electrolyte replacement supplement, athletes finally had an alternative to the “salt pills” and the idea of consuming massive amounts of dietary sodium.
Being an innovation- and education-centric company, we introduced this innovative and revolutionary product in 1996 and began educating endurance athletes about the perils of a high sodium diet and high sodium replacement during heat stress exposure. The science supporting the myriad health benefits of eating a low-sodium diet, as well as the negative health consequences of eating a high sodium diet, is overwhelming and convincing: High sodium diets have long been associated as direct or supporting causes of high blood pressure, heart disease, and many other medical conditions prominent in this and most other western countries.
Despite all of this data, high sodium advocates somehow reason that if you are an endurance athlete exercising in heat stress environments, somehow magically sodium is now your friend, and you should consume it freely all the time. Wait, what? Perhaps it’s my bias, but I’ve always found this illogical argument to be laughable and totally indefensible.
The sodium debate also brings a whole series of questions with it such as: Are some athletes naturally prone to high sweat rates when exercising in heat? Are some athletes also naturally prone to hemorrhaging large volumes of sodium during exercise in heat, when others do not?
More importantly, can an athlete who has historically shown excessively high perspiration rates and sodium losses change these tendencies through dietary intervention or any other means? To me, this is the “$64,000 question!” And surprisingly, one that not very many people are interested in answering.
Historically, if you did an event in the heat and you had cramps or other heat stress related illness, conventional wisdom said you didn’t drink enough and you didn’t consume enough sodium, so the next time just take more!
This vicious cycle of confusion around the cause and effect of high sodium intake caused more than a few athletes to suffer terribly during and after their hot events—the pain and suffering of cramps and GI distress as well as IVs in arms and trips to the hospital for hyponatremia.
Amazingly, this is still what some so-called experts in the high-sodium camp, which includes most competitor sports drinks and products, are still telling athletes today.
Conversely, we have argued since the 90s that an athlete’s sodium losses and perspiration rates during exercise are nothing more than a reflection of their recent dietary sodium intake habits—high sodium diet begets high sweat rates and large sodium and therefore high losses during intense heat stress exercise. Just like they used to say at IBM, “GI-GO: garbage in garbage out.” I like the IBM analogy for sodium because it puts it in proper context, the more you consume, the more you will excrete.
Over the past 25 years, we have worked with thousands of athletes and have seen the universal reports coming back—lower dietary sodium reduces perspiration rates and electrolyte losses during intense heat stress events, allowing the athlete to perform to their true potential despite intense heat and humidity. “But where’s the data?” the skeptics ask, as they munch on a bag of salty chips.
Unfortunately, in the 90s and up until very recently, no data existed to support our position. No study that I have found sought to prove or disprove this hypothesis. One would need to take a group of athletes, establish baseline data, go through significant dietary modification, reducing sodium and sugar intake, and then post testing.
On the other hand, the high sodium camp can refer dozens of sweat studies in which perspiration rates and sodium concentrations were measured in athletes performing tests to exhaustion in laboratories. What did the athletes eat for days or weeks before they did the tests? Doesn’t matter according to the high sodium camp.
Quite possibly an even bigger flaw in these studies than not recording or even considering an athletes dietary sodium intake prior to the test, is that they conclude that just because you lost X amount of sodium during a one-hour heat stress test, that you will continue to lose that same rate of sodium on an ongoing basis during multiple hours of competition. Wait for it…And thus, your sodium intake during exercise should match this number!
Ricky Taylor’s Post 12 Hours of Sebring race report
“During the race, the intensity of the race was high, the car wasn’t very easy to drive, all drivers were struggling with the car balance. However, physically, all of us felt very strong. I started with three stints and could’ve gone for a fourth but our strategist made the call for a change. Every driver took a ‘bomb’ on each stop and all reported they felt surprisingly fresh in the car and we all ended up doing more stints per cycle than anticipated. This meant we had more recovery time and less times cycling through the car with less driver changes. It was actually so few driver changes that we cut out almost an entire cycle and for my first time ever in Sebring, we each only drove the car two times. Normally we could mark down the lower fatigue levels to the car being easy to drive or the conditions being colder or the race being low pressure, but none of those were the case and all three drivers felt as fresh as ever. We even spoke to each other during the race, surprised how we were feeling in the car that we were going so much longer than previous years.” – Ricky
TESTING SODIUM CONCENTRATION WITH ENDURANCE RACERS
Enter the Wayne Taylor Racing IMSA team which competes at the highest level of endurance racing in the United States in events such as Rolex 24 Hours of Daytona, 12 hours of Sebring, and the 10-hour Petit Lemans event. Being the most innovative and forward-thinking team in the paddock, they have a driver science program. It took a racecar team with big budgets and lots of technology to open the door for us to address our position with scientific data. In their pursuit of victory, nothing is left to chance, everything is examined under a microscope to remove any variable or weakness that may make them less competitive. Which is why WTR has had a formal Driver Science program in place since 2016. Part of the program uses patented technology a company called CoreSyte. According to their web site, “CoreSyte designs, develops, and manufactures real-time, non-invasive digital sweat patches which measure total fluid loss, sodium loss, and potassium loss for an athlete.” You can read further about this technology and company on their website.
This finally gave us the opportunity to gather empirical data to verify what we have been seeing anecdotally with athletes for decades. One of their drivers, Ricky Taylor, is an extremely gifted athlete and race car driver. However, when I met him in 2019, he was having severe difficulty with the heat stress situation during these endurance races. Primarily, suffering excessive fluid and electrolyte losses.
As is the case with all athletes I assist, Ricky and I spoke for a long while and I asked him quite a lot of questions about his diet, training, and hydration practices to understand exactly what information he was pivoting from and his mindset. Once I explained everything to Ricky in great detail, he was fully committed to my idea of rebuilding his diet without excessive sodium and sugar. After all, the high sodium approach he had been following up until now then was certainly not working.
As Ricky will concur, it took him several months and much dedication to learn, practice, and enjoy this new way of eating. However, the results he began noticing within a short period of time provided him the necessary encouragement and reinforcement to continue with his new diet.
In addition to anecdotal feedback, we had the opportunity to use CoreSyte’s technology that allowed us to measure the sodium concentration in his perspiration. This was coupled with a somewhat low-tech method of measuring and tracking his pre-and post-driving stint body weights: getting on a scale wearing just underwear (their driving suit and helmet absorb most of the water being lost). Since they had already begun accumulating this data prior to introducing any Hammer products or diet modification, we had baseline data. This allowed us to measure the change in his fluid loss and sodium concentration in his perspiration after over a year of using Hammer products and consuming a low sodium diet.
Shortly after winning the 24 Hours of Daytona in January 2021 the results were in: fluid loss was reduced up to 25%, while sodium losses were reduced up to 40%!
Specifically, Ricky recorded a 20-25% reduction in fluid loss, and a 33-40% reduction in sodium concentration in his perspiration! The reason for the range in numbers is due to the continuous monitoring and accumulation of data over a period of hours in the car.
This is not small or insignificant by any means and affirms what we have been saying for decades: You can and will improve your ability to withstand heat and humidity during endurance exercise by reducing your daily sodium intake! Consider all the health benefits of a low sodium diet to be just the “side effects,” if you like. Just another really, really good reason to adopt this wisdom.
Salt lovers can argue (and will) that this is just one, non-double-blind controlled study and doesn't prove our position. This study is directly supportive of all scientific discovery regarding the long-term negative health effects of consuming a high sodium diet.
Use prior to, during, and after workouts to satisfy the body's electrolyte requirements with maximum precision.
Use as needed but primarily when:
- Exercise lasts for more than two hours, regardless of temperature or humidity.
- Exercise lasts less than two hours and:
- Temperature is above 80 degrees and/or 70% humidity or
- Temperature and humidity is ten degrees or more above what you are accustomed to.
Capsule Usage Instructions
Take 1–3 capsules 10–30 minutes before the start of exercise.
Take 1–6 capsules per hour as needed to maintain electrolyte balance.
Take 1–3 capsules immediately following exercise.
- Many variables - body weight, fitness level, weather conditions, acclimatization level, and physiological predisposition - affect individual electrolyte requirements, so you must do your own trials with Endurolytes dosing, under a variety of conditions, to determine what your individual needs are.
- Endurolytes DO NOT prevent heat stroke, hyponatremia, or any other dangerous physical condition resulting from overexertion in the heat.
- The amount of salt (sodium chloride) you habitually consume in your daily diet largely determines the amount of salt, you will need to consume during exercise and races. If you consume a high-salt diet, you will either need to increase your hourly dose of Endurolytes or use Endurolytes Extreme.
- We include ginger root in the Endurolytes and Endurolytes Extreme capsules because it is very soothing to the stomach and can help protect against nausea and other stomach issues. However, some of ginger's naturally occurring compounds—zingerone and capsaicin—can have a burning effect on the mouth and throat if the powder comes in contact with them. We therefore recommend that you DO NOT open up the capsules and swallow the contents. Consume the capsule whole for best results.

No more cramps~ EVER!
Endurolytes are my GoTo for ALL my rides…summer, winter…I like that I can keep calories and hydration needs separate. The capsules work perfectly for me, and I even keep them on the kitchen counter to take on summer days whether I’m riding or not.
Hi Dusty, Thank you for the review, and decades of support! Cramping is old school. Cheers, Brian
Hammer nutrition is the best!
Always speedy delivery of a fabulous product!
No headaches this summer!
I love these for long runs, especially during the humid summer here on the east coast. My stomach cannot handle most drink mixes, so taking these with water is my go-to instead of getting my electrolytes through some sort of drink mix. I'll take 2-3/hr during a long run or race, depending on the weather. They guarantee that my electrolytes stay balanced- no more post-long run headaches for me! Thanks Hammer!
Endurolytes kick in immediately. I not only use them for cramping but also to minimize a hangover after an evening of revelry. I’ll take them in between drinks and during the night when I wake up. This combined with water helps to balance out my electrolytes in a way that water alone doesn’t.
