Product Overview

Replaces key minerals lost in sweat

Dehydration in horses has serious consequences. In order to keep your horse properly hydrated and performing his best, it is essential to supplement his diet with salt. Neither hay, pasture, nor fortified grain contain enough salt (sodium chloride) to meet your horse’s needs, and not all horses can get their requirements from a salt block alone. Feeding a well-balanced electrolyte supplement like SmartLytes can supply the sodium chloride your horse needs, in addition to the other electrolyte minerals that are lost in sweat - potassium, calcium, and magnesium. Supplying these electrolytes will also encourage your horse to drink more water, rebalancing his fluids and helping to ensure proper digestion of feeds. 

SmartLytes was carefully formulated to mimic the mineral losses in equine sweat. This cherry-flavored powder is sugar-free and contains trimethylglycine (the osmolyte betaine), to help cells maintain normal fluid levels. What a smart electrolyte!

SmartLytes® Powder is rated 4.4 out of 5 by 457.
Rated 1 out of 5 by from My hoover of a horse won't eat it. It's been heinously hot here, to the point where my horse is sweating at a standstill. I wanted to add electrolytes, but she won't eat these. And my horse is the least picky horse ever, eating whatever she can fit in her mouth. The powder is supposedly cherry flavored, and it smells like cherry cough syrup,so I can't imagine it tastes much better. I think she'd probably prefer unflavored powder since she likes her salt lick. Sad, because supplements are so expensive these days.

Rated 1 out of 5 by from Not Picky Eater Approved Unfortunately while they say it is picky eater approved, that is not the case. Couldn’t get my horse to eat it. Tried easing it into his diet, adding other treats and things to try to get him to overlook it. No luck. If this is in his feed at all then he won’t touch it. Such a bummer.

Rated 1 out of 5 by from Couldn’t even get my horse to try it. Unfortunately I have offered this to my horse 4 times now and he won’t touch it . We tried letting him lick the powder, putting it in his stall water bucket, and offering it to him after a hard ride and he won’t touch it. I know it’s not lack of thirst because as soon as we offer him clean water he drinks it. Additionally we have used other brands without issue so it’s something about this product that he just doesn’t like

Rated 5 out of 5 by from Great, cost effective electrolyte! I started my horse on SmartLytes Powder over the winter after my horse went to the clinic for dehydration. I quickly found out that he was not drinking enough this past winter, even with heated water troughs and buckets. I quickly added the SmartLytes Powder back to his diet, and decided that he would receive an electrolyte year round to encourage him to drink more! The SmartLytes Powder is picky eater approved, and my horse quickly licked his bucket clean when it was added. Now after our rides, he gallops off to get a drink of water. I am hopeful that he is at least drinking more than he was previously, and feel relieved that it seems to be encouraging him to drink more regardless of the season and weather! This will definitely be a staple in his SmartPaks!

Rated 5 out of 5 by from Palatable and helped my horse pop a sweat! I switched my Cushings horse to this electrolyte to minimize his sugar intake. He is not usually a picky eater and this was no different, he licked his plate clean, as usual! He stopped sweating this summer and part of our vets advice was to double his electrolyte dose, we did that as well as adding a larger fan to his stall and he started sweating again. Every horse is different but it’s worked well for my 21yo gelding. I think it stinks a bit but my husband thinks it smells like citrus, either way as long as the horses eat it, I’m good!

Rated 5 out of 5 by from Great product! I bought this a month ago because here in Texas we are dealing with extreme heat and drought conditions. Average of 107 degrees for a while now. It is helping h keep the horses drinking and have not had any issues in spite of this heat.

Rated 5 out of 5 by from Definite win! My horse sweats heavily, and an electrolyte is necessary, particularly in the hottest months. She eats this right up. Granted, she is not a picky eater, but she's had no palatability issues with this powdered electrolyte. She seems to recover well from being ridden in the heat, and I noticed that she used her salt block less when the electrolyte was added.

Rated 5 out of 5 by from Smartlytes are a big help! From May through September I add Smartlytes to my horses feed, since he is an older horse and the hot humid days can be hard on him. My vet also recommended to our barn manager to increase hay and electrolytes during the poor air quality conditions.

Rated 1 out of 5 by from Not palatable My horse hates this...he will go to his hay before his grain when this added. I also tried it on my other horse who literally eats everything and he dislikes it as well. Unfortunately have to throw out this portion of his smart pak

Rated 1 out of 5 by from SmartLytes Powder Horses actually don't like it. They prefer plain loose salt.
