Who uses Endurolytes or salt tabs etc.

Many persons use them, and I have used them.  I haven't had any issues taking 2 - 3 every hour on my long training or racing days, especially when it was warmer.

Everybody is different, and if they work for you then that's a good thing.

I've taken the Hammer Endurolytes with no issues, and I believe they may provide a benefit, but who knows.

I switched to Salt Stick Caps for my HIM, and have had no issues so far.  I can take 1 per hour, instead of having to take 3-4 pills.  My main concern is cramping and staying hydrated.

Do they help?  I don't know.  Do they hurt?  I don't believe so.  This is my first long distance race, so we will see.  I just want to make sure i'm replacing enough of my Electrolytes to finish strong and not bonk.

I bike with a guy who uses salt caps or whatever they are called.  One century ride a few weeks ago he forgot them but assumed his carbo-pro has electrolytes in it.  He ended his day in the hospital with 2 IV bags.  Diagnosis was dehydration and low salt.  Salt does help you retain water as well to stave off dehydration to a point.

Take it with a grain of salt.  It is just an n=1 experience.  YMMV.  Also I am not a doctor but I assume if you think there is a positive effect even if it may be placebo, go for it.

I'm starting to move toward the "less is more" camp.  For anything under 2 hours, I rarely have more than a gel and water.  For longer workouts, I carry Endurolytes in addition to my Infinit.

I rarely use them, but if it is really hot and humid out and I'm sweating a lot, I'll supplement with 1-2 per hour.  They seem to stem off muscle cramping for me since if I don't supplement on those really hot days, I cramp up a bit (and it's not fluid).

I carry them just in case. If it's really hot, sometimes I end up drinking enough water that the electrolytes in my nutrition isn't enough and then I add in a capsule or two. But most long rides, runs and races, I get plenty from my nutrition.

I use Shark Salts.  400 mg of Na per pill.  Endurolytes are only aobut 40 mg / pill.  I'd have to take 10 or more to get enough Na.  And Shark Salts has more than just Na. 

When I get in enough electrolytes, I don't pee as much.  It seems I retain the fluids I'm ingesting. If I don't supplement with Shark Salts then I pee almost as fast as I drink.  Sometime, I want to do a sweat rate experiment with and without electrolyte supplements to see the difference in weight loss.
