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 4.5 out of 5 by 453.
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.

Rated 4 out of 5 by from Easy way to 'eloctrolyte' my horses! Existing in Florida's intense and humid summers are punishing on my equines. This is such an easy mess free way of getting electrolytes into my 3. Initially when I first started putting this in their feed they would leave a bit. I have to really mix it in with their food so they eat it up. My one mare is still picky hence the 4 stars and not 5

Rated 5 out of 5 by from Good value Awhile ago I had ordered this product and it came in pellet form . My recent order came in a powder . I stopped using this as I had a full bucket of Salt lites powder at home . Until that is gone I won’t reorder this particular item .

Rated 3 out of 5 by from Great product! This is a great supplement and smells fantastic but unfortunately my super picky pony wouldn’t eat anything that had this on it. I tried mixing it with applesauce to no avail

Rated 5 out of 5 by from G Great for travel , I cut these off and save for camping trips. Keeps it nice and fresh instead of a jar.

Rated 4 out of 5 by from So far so good Switched to the SmartLytes Powder after the pellets arrived inedible. Wanted some electrolytes for my mare and thought the pellets would be gobbled down easier with her grain than powder form. However, after years of all going smoothly, the smart paks arrived with an odd smell (just the electrolytes) and she refused to eat them. So, I switched to the powder. Once in awhile, the powder will still be in her manger from morning feed but, eventually, she licks it all.
