Rated 5 out of 5 by from Easy to use, cost effective, no added sugars Bought for my heavy sweating OTTB who can NOT have extra sugar. He loves it and it keeps him going strong in the summer heat!

Rated 2 out of 5 by from Shortchanged on amount of product This product in the 5-pound bucket should have lasted 80 days at one ounce per day using the scoop provided. It didn't even last 2 months before I had to re-order. Buyer beware - you might not get what you are paying for.

Rated 5 out of 5 by from My horses consistently drink better I have tested my guys with five gallon pails, plain water vs. Apple-A-Day water... both consistently go for the Apple water first. Very important as I am conditioning for endurance, nice to be able to carry a few scoops in a Zip Lock baggie to flavor the water at holds to encourage drinking.

Rated 5 out of 5 by from Only electrolyte my horse will eat! My super picky, ornery old OTTB sweats like a pro in the summer. This is the only electrolyte that he will actually eat!

Rated 5 out of 5 by from One of my feed room staples I’ve been using this brand of electrolyte for years. My picky eaters eat it no problem mixed in grain, even though it doesn’t have any sugar and keeps everyone drinking. Super economical especially in the larger buckets.

Rated 5 out of 5 by from Best electrolyte there is Been using apple a day by Finish Line for decades... palatable...smells great and has no sugars...a great electrolyte your horses will dress on their grain for best delivery

Rated 5 out of 5 by from Great Taste! I bought this about a month ago after having a hard time getting my horse to take an electrolyte supplement he now takes this. It has kept him drinking through the cold weather we had had move in and he does not pick things out of his food anymore.

Rated 1 out of 5 by from ick Neither of my horses will eat their grain if I add this. Throw away

Rated 5 out of 5 by from Picky eater approved My horse is a super picky eater, and these are the only electrolytes she eats without questioning or refusing. She sweats like crazy year round but won’t touch a salt lick, and these electrolytes do a good job of replenishing her lost salt and keep her drinking consistently. Good price too.

Rated 5 out of 5 by from Favorite Electrolyte I've been keeping a tub of Apple-A-Day in my car for years now due to the fact that you never know when electrolytes might be needed no matter what time of year it is. I've found Apple-A-Day to be the best bang for your buck and most horses like it either in some moistened grain or in their water - although I have had a few horses resist eating it on their own which is the only reason I gave it four stars in palatability. That being said, because this is such a fine powder, I normally keep a syringe with the tub and will dissolve the powder in the syringe to administer to finicky horses that need the help. The value is unbeatable and unlike many other electrolytes, there is no extra sugar.

Rated 3 out of 5 by from I'm sure it's great..if only my horses would EAT! I'm sure it's a great smells like apple sweetarts and I'm tempted to partake myself. Unfortunately, my semi-picky eaters (all 4 of them) won't eat their feed if I put the full dose on (1 scoop...I'm lucky if I can get them to eat their feed with 1/2 of a scoop). My intent was for electrolyte replacement after work or on those hot humid days where just living makes you sweat. I've been trying to give daily to get them used to it but after 2 weeks, the most I can hope for is to give 1/2 of a scoop and even then a few will leave some of their feed.

Rated 5 out of 5 by from Perfect Electrolyte for my herd! I purchased this after switching from Apple-Elite Electrolytes due to the price difference and the fact that Apple-A-Day doesn't have dyes in the ingredients. It is a little bit dustier of a powder but my horses didn't mind and they have been drinking more water and continued to work in hotter climates just fine! As long as you put some water in your horses grain when you feed this supplement you should be fine! I really like that on the container it specifies how much to feed on that day depending on their workload! The bucket is sturdy and heavy-duty and will stick around long after the supplement is consumed!

Rated 2 out of 5 by from Horses dont like it My horses wont eat their sweet feed with this supplement. Can I mix it in their water and if so, what is the dosage?

Rated 5 out of 5 by from Very Palatable Electrolytes My favorite electrolytes- east to feed and extremely palatable.

Rated 5 out of 5 by from Best Electrolyte I have used [This review was collected as part of a promotion.] I have used this for probably more then 10yrs..Not 1 horse has ever refused it and Every horse here has been hydrated even thru HOT California Summers..I do feed it in their feed Year Round right now 5 horses here and all eat it..Only product i will use and Love the Finish Line Products Never dissappointed.
Date published: 2020-01-18
Rated 2 out of 5 by from Horse won't eat it I thought this was an inexpensive alternative to some of the other electrolytes out there, but unfortunately, my horse found this formula to be completely unpalatable. Switched to Smartlyte pellets.

Rated 5 out of 5 by from Great Product [This review was collected as part of a promotion.] In So Calif it gets HOT Finish Line Products are great..The horses eat the Apple day on Top of their Grain everyday..and water consumption has Never been a problem..Terrific Product have used it for years.

Rated 3 out of 5 by from Not my favorite anynore Use to be my favorite brand but after trying some others I noticed this is very powdery and clouds up. And less product for the value compared to others
Date published: 2019-09-05
Rated 2 out of 5 by from only 2 star for my application I'm an endurance rider, I usually put electrolytes into syringes mixed with applesauce. This product has sodium bicarbonate as an ingredient. This makes the mixture fizzy. The byproduct of that is the syringes build up pressure and the plungers pop out after awhile. Then the mixture goes all over. I do not recomment this product if you plan on carrying it around mixed up in syringes. I've no idea if it works since I was only able to use half of a syring before all the rest of the mix was lost. I won't use it again that way.

Rated 3 out of 5 by from Only one of my horses will eat it This was recommended as a low sugar electrolyte and unfortunately my horses won’t touch it.
Date published: 2019-07-16
Rated 2 out of 5 by from Helps if you can get your horse to eat it! This does help keep horses drinking, but even our least picky eater does not like this stuff, even mixed with sweet feed! I tricked them into getting a few bites in but now as soon as they smell it they won't go near their feed.
Date published: 2019-07-01
Rated 5 out of 5 by from A must have [This review was collected as part of a promotion.] I've been using this for years. Great product that i can't do without.
Date published: 2019-07-01
Rated 5 out of 5 by from Great product and Affordable I've had my 5 year old future Endurance horse on this for the past year. I love it, it's very cheap in the biggest bucket yet a quality product. My horse cleans his food bowl every time though he does get heavily soaked grain since he's choked 3 times in the last 4 years thus the powder is dissolved. If fed dry, it is a very fine powder, and has a strong apple smell and flavor, Patriot's an apple guy so he loves this stuff.
Date published: 2019-06-01
Rated 4 out of 5 by from Quality product My horse tolerates (does not love though) this powdered supplement
Date published: 2019-05-14
Rated 2 out of 5 by from My horse wouldn’t eat it I’ve been using this supplement for about two months, and my horse has stopped eating it. He isn’t a super picky horse, so I was surprised by this. I tried it in feed, and he was leaving a lot left over! I think it’s a fine product if your horse likes it though!
Date published: 2018-10-02
Rated 4 out of 5 by from Strong flavoring Gets the job.done and most of my horses eat this. It is a very strong apple flavor so some of the picky eaters actually do better with a flavored pellet.
Date published: 2018-08-21
Rated 5 out of 5 by from love it! my very picky 13 yr old mare loves is with a little water in her grain, she licks the bowel clean every time! My 3 yr old love it too! definitely helps, we will have 100 degrees plus for weeks at a time. works great for me! Some of the horses at the barn did not like it. i like that it is a powder so i can add water to my horses grain because that is the way she likes it and i can add it to water when traveling because i know she likes the taste of apple-a-day (she is very picky about her water too). highly recommend!
Date published: 2018-08-09
Rated 4 out of 5 by from Bring on the pellets please! This product is a very fine powder, which I know my horse doesn’t like the feel of on the end of his lips and mouth. I was desperate though to get an electrolyte because of the hot, humid Minnesota days! I have had to douse it with molasses to get him to eat it. I think this is a great product, but would love love love it in a pelleted form.
