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 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 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 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 4 out of 5 by from Only 4* because... Smartpak was incredible in their customer service. My mare didn't like this at all. She would eat all around it and leave any grain that was touching the powder. I let them know and they completely refunded me! I was quite shocked but a very satisfied customer! Thank you Smartpak for being so awesome!

    Rated 5 out of 5 by from Makes my horse drink!! I bought this after my horse had a "minor" colic that entailed him spending four nights at the vet's hospital. He had somehow gotten dehydrated and his system stopped working properly. We added electrolytes to his supplement pack to ensure he drinks enough water, and now we are all thrilled by how much he drinks!! Yay for Smartpaks!
    Date published: 2014-09-17
    Rated 5 out of 5 by from Great for heavy work! I used to use some other electrolyte that i would have to buy in buckets by my vet. I found this that was cheaper and had a coupon code so i thought, why not! kept all my horses drinking! so before and after i go to a show i give them each 1/4 to 1 scoop, depending on the heat and how hard they're working. If im ever worried about colic or working them hard, i just add to grain (sometimes add water to make it stick) then I know they're drinking. I always keep a small bucket around!
    Date published: 2014-09-12
    Rated 3 out of 5 by from Won't eat it! My picky eater mare won't eat this at all, she cleans her bucket completely except for the tiny white powder despite mixing it in...have tried for a month! :(

    Rated 5 out of 5 by from Awesome supplement ! I chose Smartpak smartlytes because it had excellent ratings and was exactly the product I was looking for.
