Replaces key minerals lost in sweat

  • Helps to keep your horse hydrated
  • Includes trimethylglycine to help cells maintain normal fluid levels
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 4.5 out of 5 by 427.
    Rated 5 out of 5 by from Wow! I'm impressed honestly. I used to feed another electrolyte but the smartpaks are so convient and my horse actually likes this one. She went on a drinking strike during winter and after two days on this she started to drink again. And it's affordable .. also it smells SO good

    Rated 5 out of 5 by from Great deal My gelding is prone to colic and with the cold weather he was not drinking enough. This helped him and is full of other good minerals that most other electrolytes don't have.

    Rated 5 out of 5 by from Great product! I bought this supplement to give to my horse to supplement for his lack of being able to graze and no source of selenium. Not only does he love it, but I know he is now getting everything he needs.

    Rated 5 out of 5 by from Great Electrolyte at a Value My ottb went from drinking 1 bucket to 2.5 buckets within a week of being on Smartlytes. He needed the increase in water intake and is doing much better in our humid hot Florida climate.

    Rated 5 out of 5 by from I started my mare on this 2 months ago. She lives outside and would be sweating just standing in her paddock in the hot summer months. I also noticed that she didn't drink very much and would always come in with a dry tongue. Now, she sweats more when she is ridden and her tongue is much wetter. She had a little trouble eating it at first and I had to mix it in with some sweet feed and a tiny bit of water but now she eats it dry on to of her morning grain.

    Rated 5 out of 5 by from Great choice for a picky horse I have been giving this to my 13 year old Andalusian tb cross who is a event horse. I had tried few different brands but he really really loves smartlytes. I recommend this product to anyone and am current getting the rest of my barn on board

    Rated 5 out of 5 by from Dependable formula My horse is on complete supplement, BUT this summer was so hot and she was sweating so much that she needed extra electrolyte - look no further than trusted Smartpak. I have to say that her blah improved immediately.
    Date published: 2016-08-25
    Rated 4 out of 5 by from This is a great electrolyte While my horse didn't appreciate the powder form, and I had to mix it with some other stuff for her to eat it, it actually is a really good product. I noticed that switching to a different popular electrolyte her stools were drier. So I switched back to Smartlytes pellets this time. After being back on smartlytes for three days her stools are back to normal. Seriously a great product here.
    Date published: 2016-08-14
    Rated 1 out of 5 by from I really wanted this to work! I bought this month and my horse, who I thought would eat anything, would not eat any of his SmartPaks if this was mixed in. Not even if dinner was mixed with applesauce! It's the first thing he's ever refused.

    Rated 1 out of 5 by from Horse dislikes berry taste. My mare would not eat this. Apparently she does not like the berry taste. She does however like Farnam's Apple Elite and licks her feeder dry.

    Rated 5 out of 5 by from Amazing Customer Service I bought this supplement for my horse who doesnt drink much water and has a hard time with the heat and the improvement i saw was breath taking. I will most definitely buy from SmartPak again!!
    Date published: 2016-07-12
    Rated 5 out of 5 by from My horse loves it more than me! I bought this before going to a show in MS (10 hours from home) with my mare who is a bit funny about water. I started her on it the week before we left and she loved it! She's also picky about what's in her grain and she didn't hesitate to rate with the supplement in it. Because it was so hot in MS I look up recipes for electrolyte popsicles for horses and made one using these electrolytes and she ate every bit of it! Overall really happy with the results of this supplements.

    Rated 5 out of 5 by from Only electrolytes my horse will eat! This is the only brand and in powder form only my stubborn Appy mare will eat.

    Rated 4 out of 5 by from Works, but not picky eater approved I started this to my horse's supplement regimen, like I do every summer, though typically I would give her SmartLytes Pellets, since she's so picky. Last summer, she left more than half the pellets every meal, which was a complete waste of money. I ordered a does and a half of the powder this year hoping she'd eat it, like she does her vitamin E so easily, and she's still leaving it. Thank goodness she's not leaving enough that it's not working (especially since I give her a does and a half). It's still wasteful, which is frustrating, but I know she's getting enough, because she drinks 2 full buckets in her stall everyday, and has been drinking really well at horse shows this summer too! Good product, but needs to work on flavor more I guess, since mine picks through the pellets and the powder, but none of her other supplements!

    Rated 5 out of 5 by from Love that it's in powder form My horse just started on Smartpaks. Ohh my how wonderful he is doing He was fine before but with these supplements he has a little skip to his day Happy happy gelding He is a beautiful Reiner too
    Date published: 2016-05-06
    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.
    Date published: 2015-12-26
    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.
    Date published: 2015-10-12
    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.

    Date published: 2015-08-04
    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
    Date published: 2015-07-24
    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.
