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!

Rated 3 out of 5 by from Good product- smells if you wet food We wet my mares food and the smart lyte gave off a funky odor when wet which discouraged my mare from eating. I'm sure it works much better for those that don't need wet food and aren't picky eaters!

Rated 5 out of 5 by from Awesome product for any level horse! I have been using Smartlytes powder for over a year and it not only helps my pasture puffs during the hot summer months, but also my endurance horse who truly NEEDS it to stay hydrated during conpetition! CB Firestorm uses his Smartlytes to conquer 50 mile rides and never skips a beat. We add it into his daily grain and also syringe it during races during a time crunch. Being a half "stock" endurance horse (Appy) isn't easy, but Smartyles makes it pretty darn easy to keep up and complete our rides with ease!

Rated 5 out of 5 by from Tastes just like salt :) Glad I am able to put this right in my geldings grain he needs to drink more water now during these cold winter months. Don't think he minds the salty flavor at all in fact I'm a little jealous

Rated 1 out of 5 by from My horse won't eat it! My horse does not like the powder and will not eat it. I have had to go to the pellets, which cost more, of course, but he is eating it now. He is a horse that does not like to lick a salt block. He has had a lot more energy now in the summer months and is sweating better also.

Rated 4 out of 5 by from Great choice I add electrolytes into my mare's feed when we travel for shows, mostly just as precautionary, to make sure she keeps drinking. She doesn't miss a beat cleaning her pan when these are added. They must be super palatable. I'm sorry that they are no longer available in a smaller size container. That one was perfect.

Rated 5 out of 5 by from Loving this elyte! I need my horses to drink and drink well. They are worked regularly and then 25-30 mile distance rides 1-2 times a month as endurance horses in training. They sweat heavily and it's necessary to replenish those minerals/salt lost. I have tried three products already and this one has been the best thus far. I have found that it sticks better when I wet their feed (they get hay pellets and a little dry pelleted feed and it will sift to the bottom of their dish if I don't wet it down). My gelding drinks so well, peeing regularly (most of it being about as clear as water-no joke). My mare actually needs a bit more than the regular dose to get her drinking and going well. I also premix doses in those fruit sauce pouches to draw up into syringes at the vet holds during competition. They both are doing great on it.

Rated 5 out of 5 by from Smells So Tasty I'd Eat It! I bought this for my eq/jumper gelding on a whim after using Apple-a-Day for years (nothing against them, just wanted to try something new). My horse is a big time sweater and is in heavy work, so he needs a good electrolyte that he'll eat instead of leaving in the bottom of his feeder. He seems to really like the cherry flavor - it smells delicious! He's not a picky eater, but he does tend to pick around some supplements and eat them last... Not this one ;)

Rated 3 out of 5 by from Doing its job but my guy isn't crazy for it I live where it's extremely hot an humid so wanted to add an electrolyte to my smart pak so I didn't have to keep buying from the feed store and running out. I'm sure it is doing its job but my guy isn't crazy about it and has been leaving it It smells good tho

Rated 3 out of 5 by from Neither horse will eat it. Last summer, my gelding ate this in his grain without a problem. This summer, he isn't finishing the grain that touches it and my mare won't eat her grain at all if she knows this is in there. I am going to try the pellets! If your horse will eat it, it's a great value and helps encourage drinking in the summer months.

Rated 5 out of 5 by from Great! Bought this for my recent road trip. Over 600 miles in 13 hours and my horse did awesome. She was ready to roll for 4 days of racing

Rated 5 out of 5 by from Love, Love, Love this supplement!! This supplement is the best electrolyte on the market. My horse is not usually a picky eater but when it came to electrolyte he would not touch a single one except this one! I feed this all year round. As a lower level eventer my horse sweats A LOT in the summer. At events he would never drink water and it always made me nervous. After being on this supplement he drinks water at shows and at home. In the winter the supplement encourages my horse to drink a lot more water than before. I absolutely love this product and it has made a huge difference in my horse!

Rated 5 out of 5 by from Love it!!! Started both of my mares on this product a month ago, and they have done wonderfully. Both of my mares are picky about drinking water and will consistently be drawn during the winter and through the first months of the summer, since beginning Smartlytes they are not drawn drink like try should!

Rated 1 out of 5 by from Horse wouldn't touch it My horses normally take supplements without a problem but wouldn't touch this. I tried both on food and mixed in water bucket.

Rated 5 out of 5 by from Even my picky eater likes it I tried this since I love all smartpak products but was unsure if my one picky eater would eat it - he does! No worries of staying hydrated in Florida this year:)
Date published: 2015-05-19
Rated 5 out of 5 by from Delecious I didn't know if my horse would eat this since it is just a powder, but he LOVES it. I don't even feed any extra grain with it. It smells so good that I want to try it. :)
Date published: 2015-02-17
Rated 5 out of 5 by from Great Product I tried this product after I realized that most of the powder electrolytes I was giving my horse were staying in the bottom of the feeder instead of her ingesting it. I switched to the Smartlytes in the pellet form and love them. She eats them better and I have seen little to none left in the feeder.

Rated 5 out of 5 by from My horse loves them!!! My horse has been on SmartLytes for about two months now. I started him on them because he wasn't drinking much at all when the temperatures got cold. He coliced extremely bad last year leading to colic surgery, so I want to prevent a repeat incident from ever happening again! He absolutely LOVES these! He eats them right away (I'm pretty sure he just thinks its just seasoning for his grain haha). Super happy as usual with another SmartPak purchase!

Rated 5 out of 5 by from Convenient + I purchased this for my older horse. I wasn't sure he was getting what he needed. I was impressed with the questions that helped to identify what he needed. It is great to know that he is getting what he needs to be healthy and he is so happy. The Smartpak convenience is wonderful. Drummer is a very happy boy.

Rated 5 out of 5 by from Great product. i bought this for my FEI horse that has PSSM. He's a picky eater and had not problem with it.

Rated 5 out of 5 by from The BEST electrolyte in the market! After trying multiple electrolytes that my horse would not touch, he loved this one! I like it because it is sugar free and truly has an effect. My horse is known to sweat a lot even standing still in hotter weather. The water intake has been noticeably increased and he has a healthier coat due to hydration! Thank you SmartPak for making such a wonderful product at a reasonable price! This supplement is highly recommended!

Rated 3 out of 5 by from my horse won't eat it My horse will not eat this. Which is weird cause he eats everything. So I don't know if it works or not. He eats all his other smartpaks just fine.

Rated 5 out of 5 by from Great resultd Have been using Smartlytes for about 3 years. This supplement leaves others behind when comparing ingredients. My horses love the flavor and they recover well from strenuous exercise.
