S!Caps
S!Caps are the only electrolyte product that keeps my legs from cramping during gravel bike racing.
Developed in 1995 by scientist and ultramarathoner Karl King, SUCCEED! Electrolyte Caps have become The Gold Standard for Electrolyte Replacement™.
S! Caps are 100% electrolytes. Beware of imitations that use ineffective, non-electrolyte fillers such as sugars or the carbohydrate maltodextrin.
The First Aid patrol at the Western States 100 found me along the trail at 52 miles suffering from leg cramps. They were kind enough to share their Succeed S Caps (half their stash) to get me going and get me through to the finish. I recovered faster than I thought I would. I have used S Caps in all of my 100's (and ultras) since then.

Electrolyte supplementation is primarily about sodium replacement, and S! Caps deliver more for your money than any other supplement. Don't waste your money on imitations that supply less than half the sodium of S! Caps and will let you down when the heat is on. Of course, others have tried to imitate this formulation, but have failed to deliver a product as good as S! Caps.
Nutrition Facts labels normally list sodium content as the element, but some products have misleading labels that express the sodium content as sodium chloride (table salt). This leads the unsuspecting reader to think that they are getting more sodium because the numbers are large.
The S! Caps label lists sodium as the element, 341 mg per capsule. If you want to compare to other products that list the sodium as sodium chloride, S! Caps supply 867 mg of sodium as sodium chloride.
We encourage you to read labels so that you understand why S! Caps are the superior electrolyte supplement. See our Integrated Solution page to see why we don't load up our formulations with the “kitchen sink” list of ingredients that are present in quantities too small to have any real effect.
S! Caps provide all of the major blood plasma electrolytes that other formulations are missing [ sodium, potassium, chloride, bicarbonate, and phosphate ]. S! Caps contain ONLY electrolytes with no fillers or vitamins that aren't really needed in an electrolyte formulation.
What about magnesium? “Magnesium is another intracellular ion that, like potassium, is lost in sweat and urine during exercise. But the losses are trivial. There is no published evidence showing that magnesium deficiency is either common amongst the physically active, or that magnesium supplementation can either increase the intracellular magnesium stores, or enhance performance.” Dr. Timothy Noakes Sports Nutrition: Fluid, Electrolytes, and Minerals (Report from the World Forum on Physical Activity and Sport, Quebec City, Canada, 1995.)
S! Caps give you the electrolytes you need without unneeded stuff taking up room in the capsule.
Heavy sweating during athletic performance lasting for many hours can cause loss of critical electrolytes from blood plasma. Modera te loss of electrolytes can degrade performance, while heavy losses can lead to hyponatremia (low blood sodium) that can cause collapse and death in extreme cases. Sports drinks can provide adequate sodium input for a few hours of exercise, but are insufficient over longer periods. Energy bars and gels are low in sodium and should be supplemented with electrolytes. SUCCEED! BUFFER/ELECTROLYTE CAPS provide electrolytes that are commonly found in blood plasma (sodium, potassium, chloride, bicarbonate, phosphate), in the proper proportions for hours of exercise. When taken with sufficient water, they help the body maintain good hydration status, which allows performance at a high level. As we claimed back in 1995 before others had even thought about appropriate electrolyte replacement in endurance events: they also contain a chemical buffering system that neutralizes the acids formed during heavy exercise. Neutralization of excess acid will help performance and reduce the nausea associated with exercise in the heat. Maintenance of proper electrolyte levels will reduce swelling of hands and feet after many hours of exercise, and that will reduce “hot spots” and blisters on the feet. The buffers in S! Caps also help soothe the stomach.
Endurance athletes know that dehydration and electrolyte imbalance can lead to big problems during an event, but recent studies show that dehydration can also lead to migraines. Fortunately for some people, taking an S! Cap with a glass of water can prevent a migraine that is coming on, or stop one that has started. Instead of taking medications for migraine, some people can simply take an S! Cap with water to get relief – no drugs needed, just your body’s natural electrolytes as supplied by S! Caps.

S!Caps are the only electrolyte product that keeps my legs from cramping during gravel bike racing.
I have used S Caps for several years, both during long training runs and trail races. I typically take one cap every hour and have never experienced any issues. Great product!
I sweat a lot more than the average person. I noticed I was getting fatigued during 90 minute tae kwon do classes. These really made a difference. Now I use them for any exercise, even if I don't sweat a lot. Or if I'm just cutting the lawn and sweat. I've been using them for 10 years or so.
Great product has helped me through many long runs and hikes. My wife recently started using and commented how much better she feels during extended activities in the heat.
I used these for years when running -- especially in hot weather. Bad knees pretty much stopped my running in 2000 and after having both knees replaced in 2015 the Dr advised me not to run at all on my new knees. These days I use S!Caps whenever I am working/walking outdoors in hot weather. They really help prevent cramps. I was happy I had some left over from my running days. I have purchased additional supplies of S!Caps so I always have some handy when I need them.
I learned the hard way, don't run out. I have used for 3 years. Never ever felt dead on my saddle during a long ride. Forgot to reorder in time for this past weekend MS 150. I bonked bad on Day 2 of the ride. First SAG ever. So glad I am now resupplied.
I've used Succeed S-Caps for years, and they make all the difference on long training runs, marathons and ultras. They are a critical part of my hydration strategy, enabling me to maintain my electrolyte balance even when I'm sweating a lot.
I really notice a difference when using S!Caps. I sweat a lot and will even use it on shorter (45-55 min) training runs. It does make a difference in my endurance and recovery. No other supplement makes as much difference for me.
I’ve been taking this pills to support my hydration routine for more than 10 years. They’re really amazing. So powerful but gentle on my tummy. Very convenient also to carry them for long workouts
I've been using Succeed ecaps since 1995 when someone at a 50 mile trail race gave me several when I was experiencing severe cramps in my legs and nausea. Took a Succeed cap with water and in 10 minutes I felt a lot better as the nausea went away. I continued using the caps the rest of the race without any further cramping. I met Karl King at the Ice Age Trail the next year and talked with him about Succeed and other products and continued using the Succeed electrolyte caps for all my ultras I did. When I had to end my running, I took my bike touring all over the world and have continued using the S caps for all my cycling. I highly recommend all the Succeed product and have given out the electrolyte caps to many cyclists who were cramping.
Thanks Karl!
I have been using Scaps for many years. The high sodium content is the only one sufficient for my high sodium loss. Easy of the gut and effective, they are the gold standard in ultrarunning.

I’ve been using S Caps for years. They’re the best electrolyte capsules I’ve found for keeping cramps away on long, hot, sweaty bike rides.
I have POTS and these are the only electrolyte/salt tablets my body can tolerate. All of the other ones I have tried have had horrible nausea and other side effects. These are absolutely amazing!
IOther than running the usual 100 mile races, I have run most of the state of Florida as a journey runner. So, I run 45-50 miles a day for several days in a row. I rely on S-Caps to keep my sodium levels where they need to be, especially in the Florida heat. I also find that the sodium bicarbonate settles my stomach, which we all know is a regular problem when having to force food down 10 to 12 hours a day. After I take an
S-Cap I always have a very satisfying burp.
In my 50s, I started getting cramps sometimes when hiking or backpacking. I tried various solutions with varying success, but S!CAPS combine convenience (a tablet) with unsurpassed effectiveness. No more mixing powders into water. I just take an S!CAP and drink some water out of my hydration reservoir. Five stars!
I trust Karl King and still appreciate the product he designed. At 74 I am no longer running ultra distances but still need my electrolytes balanced to avoid leg cramps at night. Post knee replacement the SUCCEED helps with difficult rehab workouts too.
I pop 1 tan every 30 minutes in long runs. I’m a salty sweater. I get nauseous with any liquid calories. S Tabs and water (along with food of course) are key to my ultra marathons.
I’ve been using S-caps since the 00’s. They have sufficient sodium to keep me running and healthy. Love them, and will use them for twenty more years.
My teenage daughter is a competitive swimmer and is in the pool for at least 3 hours 6 days per week. She was having fainting and dizzy spells. After tests her doctor found her body was not holding sodium and the chlorine was pulling it out of her. He recommended she start taking these daily. After a study to find out her sweat rate in the water, he was able to figure out how many she needed per day and when to take them. She says she can tell a big difference in her endurance in the pool as well as no more cramps. I’m so happy he had us order them and she can keep swimming.
works great for leg cramps
The balanced electrolyte combination in this electrolyte replacement make it a great way to stay hydrated while maintaining electrolyte stability during long workouts.
Either acing the contents into your preferred energy source or swallowing them whoe they are equally well absorbed.
A proven supplement!!!!
These are great at keeping cramping at bay for all my adventures cycling and running. I've had no stomach issues and they are easy to pack and carry to boot.
As a road cyclist and mountain biker who spends significant time in the saddle, I am always searching for things to improve performance. The S!Caps helped solve a cramping problem I developed a couple years ago. I have been using them for approximately the last three years and I can’t speak highly enough to their effectiveness when I’m out there on those long-distance rides in the high deserts of New Mexico. I highly recommend them.
I’ve used S Caps for nearly 10 years. I train and race in Texas heat. Due to the chemical composition, I’ve used them to help w upset stomachs in addition to adding salt to my system.
These caps were highly recommended by a neighbor who is an ultra runner. She suggested they would help me (a non-elite athlete) keep working out in our very hot and humid coastal climate. As promised, one capsule prior to my hour-long bikes and runs (over 100 degree heat index) has eliminated leg cramps and exhaustion. No digestive issues, either--excellent product.
I have used these caps since their inception first as an ultra runner and now as an endurance triathlete. They allow me to participate with just water if I do desire and not worry about what replacement is served during different races. Never a stomach upset and work fast.
I used this over the incredibly hot and humid weekend while riding long miles on country roads. Taking one pill roughly every hour was magic in keeping me going at a good pace and did not experience any stomach issues. These work great, thanks Succeed ! S-Caps

I’ve used this brand for 6 yrs now. 100 miler is 99 degree heat. Used these and water. Never got dehydrated in 27 hours. I’ve used it in hot, humid, even winter. I’ve completely stopped with any sports drinks. These help me stay balanced and cramping is non existent.
I've been taking these for years during training and for races. I can't stand the taste of the electrolyte replacement drinks so switched to S-caps awhile back. I like that there isn't any added magnesium - I don't think that's a wise thing to be taking when going on long runs so looked for a long time to find a product that didn't include it. In the summer heat, I often take a cap the night before a long run as well as day of. Always works for me to make sure I feel on track (no headaches or nausea). I don't know what I'll do if this product gets discontinued! Highly recommend it.
I need to take in a lot of salt, the opposite of most human beings.I trust this is a pure product -- have been taking it for more than 5 years and it helps me augment my daily intake.
I've tried many electrolyte products and this one reigns supreme. I run outdoors all year in the Phoenix area, so S caps are the difference between success and failure in the summer. Easy on my stomach and make a noticeable impact within a few minutes.
We have been using the capsules for many years with great success. Before, during or afterwards. Depending on the workout and what time of year. For myself. I perspire alot. So Before and after, so I do not cramp. My wife using, during workout, and or after. Highly recommended.
I've used Succeed for years while doing 50 mile horse endurance races. Its the best electrolyte I've found. Does not bother my stomach, easy to just down a couple of capsules on the fly and you don't have to drink sticky icky sweet drinks. It's great for hiking and trail riding and mucking stalls too!
I wouldn't use any other product for my 100 mile race
I've been using S Caps for years. These have saved me during Javelina Jundred, Angeles Crest 100, and triple digit heat training runs. It just helps me out as I pour sweat and salt out of my body. I will continue to use this product throughout the years.
I love the ocean and I’ve been surfing 40 plus years. Cramps will shorten any surf session and can be down right dangerous in moderate to big surf. I tried bananas, sports drinks as well as several electrolyte brands. Si caps are the best product for surf cramps My good friend is a free diver spear fisherman and he uses Si caps to prevent cramping.
It’s the best!
The gold standard for electrolytes. I’ve been using S-Caps for 10 years. It’s the only salt/electrolyte product that I will use for ultramarathons. 10 out of 10!
Been using them the last couple years as I move into the world of Ultra distance trail racing/running. Ran my first 50 mile race this summer with no leg cramping issues. Quite a change from past races of shorter distances!
I have been running for many years and have come to know what my body needs so that I can perform at my best and recover quickly. S-caps work very well for me. I like the fact that they are buffered so that it does not upset my stomach. The capsules also contain potassium which is necessary for good cell absorption. I take S-caps with my regular electrolytes because I need a little more sodium chloride than the average person. The capsules are very convenient. They are a pre-measured dose and I take one for about every hour running depending on how hot it is. I just carry them in my running belt pack in a small plastic bag to make sure they stay dry. I have been using them successfully for years. It is a very good product.
I wanted a way to get proper sodium amounts with potasium for my ultra runs (150 miles Maah Daah Hey race in ND recently) while drinking water, instead of drinking Tailwind, Scratch, etc. So I took 1 capsule every 30 minutes and made sure to consume at least 16oz of water per hour (generally more), along with my food - no issues, no cramping, and possibly even better, very litte soreness the days to follow!
When I began ultrarunning 12 years ago, I used another product (Endurolytes). I was a mess. Then I was introduced to S-Caps. Wow! What a game changer. Thank you for a great product!
I first started using Succeed S Caps back in 1996 soon after they became available. Vividly recall that I was running a 50 mile trail event in Virginia in Spring 1996, and cramping badly in my legs. A guy (who I became good friends with) started to pass me and gave me 4 of the S Caps and said it would stop the cramping. I took one with lots of water, and about 15 min, I couldn't believe how much better I felt and went on to finish the 50 mile trail event without any further cramping. Since then I've used Succeed S Caps on my bike (heart said go but knee said no), taking up long distance cycling and bike touring all over the world. I take one capsule every hour to keep my electrolytes in balance. I take them with me on all my bike tours around the world and they have saved me repeatedly in heat above 115 deg F and high humidity in Cambodia, Vietnam and Thailand. Highly recommend these capsules.
I have been using your S-caps for years, and don't know how I managed before a friend introduced me to them! I am old school and really avoid ordering anything on-line unless absolutely necessary, so I called your number on the bottle and received excellent, friendly, accurate, and quick customer service. I come from a family of 14 and now most of us, including the next generation, have started using them! So convenient to carry with you! Thank you so much for everything! You have kept me a happy runner! God Bless You All!
The best product on the market for maintaining electrolyte levels. I do 100 mile rides and would be in a world of hurt without these. THE BEST!
Both myself and my wife use the product during fitness training and mountain biking.
I personally sweat alot. This helps to prevent cramping after exercise and at night time. We having been using this product for many years with great success.

Great product. I take this product daily. When I exercise and when I don’t. It’s a great way to ensure your mineral balance when doing multi day water fasts as well.
I have not only run ultras for many years but also have journey run most of the state of Florida. S-caps are a must! Not only do they supply the electrolytes I need in the Florida heat, running for several 45-50 mile days in a row, but the sodium bicarbonate settles my stomach. All of us know how stomach issues arise when running long distances, but that base mixes with the stomach acid to produce sodium, water and C02, otherwise known as a burp - and, immediate stomach relief.
I've been using these for over 10 years. They are the best, easy to take, easy to digest. They never fail, I think the potassium is also key in these. During the long events, when I take one, I can feel the effects within minutes of taking them. They're the best and I recommend them to everyone that I can!
Being from the mid west you have to manage cold and heat and I've always found the hot humid summers a considerable challenge. I tried all the electrolite products in the local technical running stores but none worked to keep this heavy sweater hydrated and from developing muscle cramps hours into an endurance event. Eventually a work colleague and seasoned ultrarunner from the early days of ultrarunning who cut his teath in the dry Utah desert suggested S-Caps! and what a difference it made. I go aggressive with the usage (2 every hour as directed) due to being a heavy sweater and the results are good as dehydration and cramping are rarely an issue anymore.
This supplement is amazing! I have been using this product for years and have not had any nausea/GI issues since I started! I have been a distance runner and triathlete for 20 years and until I found this product I would often suffer with nausea and GI issues related to training and racing. I have literally had zero problems since I started taking it! No exaggeration...it is a game changer!
Since 2012, I have been using your succeed caps, pre-race & recovery supplements and now they have become my comfort blanket to be feel confident that I’ll be able to finish my races. I have finished at least 30+ races since then.
My goal initially was to become an ultramarathon runner, but reality hit me & I have to stick with half & full marathons. I have already bought a year worth of your supplements so I ended up using them during my races with outstanding results. I have never hit the wall & my recovery takes less than 48 hrs. I haven’t had the discipline to log enough miles, so I’ve never started a race properly trained, but with your supplements, my base training & strong mind set I have finished all my races.
I believe that you should start marketing all distances. Because a marathon for a normal human being requires similar effort than for an ultramarathon athlete needs to finish a 100K.
Thanks to Trail Running Nation podcast who introduced me to your product!
This is the best electrolyte replacement supplement on the market!!! It brought down my leg cramping down to zero. My stomach discomfort during ultramarathon training disappeared. I have been using S caps for well over 10 years now. I have occasionally tried other products, but go back to Scaps everytime.
This is the only electrolyte product I will use. A fellow runner shared hers with me on a 50K trail run. I was in dire straits, confused and depleted. After about 10 minutes my muscles started firing again and I charged up the mountain and flew down to the finish. I always take extra with me now and give them to cramping and hurting runners. This product saves runs and lives.
After struggling with marathon nutrition. I found S-Caps. Now they are the only supplement I use. S-Caps prevent my stomach from turning, replace electrolytes, and speed the recovery process!
I have been a S-caps user for years. I first realized their effectiveness while running in the high heat and humidity in Louisiana. During my runs, prior to my using S-Caps, my legs would feel like Jell-O. Knowing that I had plenty of carbohydrate stores, I looked at the possibility of having a sodium deficiency during my workouts. I wanted something that would keep my blood sodium levels where they needed to be, and S-Caps provided the solution. They are great for anyone that needs something dependable to rely on when they want to perform at their best. I highly recommend this product.
I have been using this product for many years and have taken it every time that I run. It replenishes my electrolytes.
I have recommended this product to others and they also agree that after exercise, they do not get ill effects of the hot weather.
