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 449.
Rated 5 out of 5 by from Works! My senior horse decided that he did not want to drink water while being stalked during the days of summer. I started giving him these electrolytes, and now he drinks like a pro in his stall! He gets soaked food so the powder dissolved and he eats it with no issues.

Rated 2 out of 5 by from Mare would not eat My mare would not eat her grains with these electrolytes if given in the quantity suggested. We had to give less than half of each daily dosage for her to eat her grains. I guess she does not like the taste.

Rated 5 out of 5 by from They like the taste My horses typically dehydrate during Winter months and lose weight. Smartlytes are helping tremendously

Rated 3 out of 5 by from Not a hit Unfortunately my gelding will not eat this product :(. Normally he eats almost everything but when I put this in his food, even mixed thoroughly with water, he spills his food out everywhere and refuses to eat. Really wanted to like this product. Maybe try the pellets instead.

Rated 5 out of 5 by from Keeps my old horse on water! My old gelding decided this winter that he didn't want to drink water, which lead to a mild colic episode. I had bought a bucket of this for my other horse for when I travel with him so I thought I'd just throw some on my old guy's grain to see if he'd even eat it. I was skeptical because my non-picky horse I originally got them for won't touch his grain when this is in it. However, my old guy gobbled this up! I have now added it to his daily SmartPaks and will probably keep him on it year round to make sure he stays on water. As for my other horse, I'll definitely try the pellet form for him next time!

Rated 5 out of 5 by from Very palatable! Very palatable! Horses loved it. Great value for a quality product.

Rated 4 out of 5 by from Both horses are eating it without a fuss Even the filly from TN who is in her first year of work has been sweating well and working great in the relentless Florida humidity.

Rated 2 out of 5 by from My horse won’t eat it. I added this supplement to my monthly SmartPak’s with the intention of helping my horse out during the hot summer months (May through October). I have noticed that he is more comfortable when performing in the heat, however I also noticed that he has not been eating the supplement. He must only be getting what’s on his grain.I checked his bucket today and it appears that their is powder residue still leftover from at least a weeks worth of supplements. He is a horse who usually licks his bucket clean. I would suggest that SmartPak change the flavor. Guess I will be switching to the pellet form.

Rated 5 out of 5 by from Amazing Electrolyte! I love this in my SmartPak. I put it in my horses dinner which is made up of alfalfa cubes and sweet feed grain. He eats it in his first mouthful and loves it! Always takes it willingly and clearly loves the cherry flavor. I definitely think that having this added in his SmartPak has helped to keep him better hydrated. He and I are both from Maryland, but are currently living in Florida. The severe heat is new for him and he sweats just standing in his pasture. I wanted to be sure he had something extra to help him stay hydrated. I would recommend this product. Good price and easy to use.

Rated 5 out of 5 by from Worked Wonderfully! My horse lives in a very cold area, and even though the barn is kept pretty warm, he didn't drink as much water as he needed over the winter. We noticed him being dehydrated almost all the time. We started him on SmartLytes, and within a few days he was drinking a regular amount and totally hydrated again. Worth noting, he is never a picky eater and ulcer treatment made him used to all sorts of strange tastes in his foods. He ate it very happily!
Date published: 2018-05-12
Rated 2 out of 5 by from Horse won't touch it I love the price and ingredients for this product, but I can't speak to how well it works as my horse won't touch it! He's not a picky eater, he normally licks the supplements out of the bottom of his bucket, including powders, but when this is in his grain, he won't take a single bite. Not sure if it's the smell or what. It's too bad, it's a good supplement and I wanted it to work!

Rated 5 out of 5 by from Love it Bought this product so I don't have to worry about my horse drinking enough when we travel
Date published: 2017-06-07
Rated 5 out of 5 by from Made a huge difference... I have given these to my harness race horse for almost a year. He is a very picky drinker - when he travels to race, he refuses water. After he trains, he never drinks enough. I worried about him becoming dehydrated and not being able to perform his best. The gets these every day in his SmartPaks, and they encourage him to drink. He finished 85-90 percent of his 15 gallons of water daily. He will drink a full 5 gallon bucket of warm water now after jogging. These are well worth the comfort of mind - I never worry about him not drinking or getting sick or weak during race season.

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 1 out of 5 by from Diappointed My horse hates the taste, should've bought apple. A waste of my money
Date published: 2017-01-24
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 I bought this to keep my horses drinking and to prevent heat stress issues. It did just that.

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
Date published: 2016-09-02
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.
Date published: 2016-07-19
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.
Date published: 2016-07-13
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.
