    SmartGut® Ultra Pellets is rated 4.7 out of 5 by 226.
    Rated 5 out of 5 by from Super product We have several horses on this product and are very pleased with the results.

    Rated 5 out of 5 by from It's working for my ulcer-prone Warmblood After treating my horse for ulcers, I used a more expensive treatment for prevention. When I took him off that, he developed ulcers again. After treating the second bout of ulcers, I put him on SmartGut Ultra Pellets. I'm very pleased to report that a recent scope showed no evidence of ulcers, which confirmed that this supplement works.

    Rated 5 out of 5 by from really helps i used this supplement on my 19yo gelding for his whole life- it really help him to keep up with me! I can totally tell when he's off it- he starts to show bad behavior and refuses to do everything. when he's on the supplement- he can and will go wherever i'll point him to. A little too pricy though He never shows bad behavior or pain in his belly while he's on it. thank you SmartPak

    Rated 5 out of 5 by from Working well and my picky eater is liking it My horse was having some hard to diagnose issues that included obvious pain/discomfort but not colic, refusal to work, and a very poor attitude in general. After a gastroscopy revealed some sort of irritation in his gut, the vets recommended SmartGut Ultra in addition to some other things to manage stress. Collectively, these seem to be working. His happy personality and willingness to please have returned.

    Rated 4 out of 5 by from best so far I have owned a mare who cribs for 10 years and have tried many different products to help her . This is the best product I have found so far to help decrease her cribbing, she's actually able to go without her collar occasionally

    Rated 4 out of 5 by from Keeping my mare going Seems to be helping my mare, glad I tried it. My mare is a fussy eater and she will eat these pellets right out of your hand. It is worth a try to help horses with ulcer symptoms.

    Rated 5 out of 5 by from Great ! I had my mare on 30 days of omeprazole and still not eating that great, most symptoms had subsided, kicking at belly when cinched, ear pinning, ect but not until about 3 or 4 days on the smart gut ultra did she start eating all her food, now she is eating 3 meals a day without any hesitation, all ulcer symptoms are gone and she is happy as can be !

    Rated 5 out of 5 by from Love it We have been fighting ulcers in my show horse for a year. We were treating him with a preventative however they still came back. I started him on Smart gut ultra about a month ago. His attitude has changed, he has started to put his weight back on and just over all doing better.
    Date published: 2016-05-16
    Rated 5 out of 5 by from Research suggests the ingredients may help ease symptoms of gastric ulcer syndrome, so worth a try after treatment. So far, so good! And, not too expensive which is always helpful!

    Rated 5 out of 5 by from AMAZING!!! I bought the SmartGut Ultra Pellets for my horse after trying for several months to treat his diarrhea. Vet said she could find nothing wrong, but might be start of an ulcer. My other horse had passed away and the stress seemed to have created a problem that many of the other products I tried on him could not help. Within a week of being on the SmartGut Ultra Pellets he had no diarrhea! I couldn't believe it! He is 27 years old and I thought that he was going downhill, but now he is playful and sassy again! Thanks SmartPak for creating a product that helped my boy!

    Rated 5 out of 5 by from Great Product!! My horse had two impact colics over the winter and 2 gas colics along with being super gassy. Every since putting him on this we haven't had any colic issues ( knock on wood ) and he no longer has excess gas =D He has been much more happier. Happy horse= Happy owner =)

    Rated 5 out of 5 by from Vet suggested this Mini's needed gastro guard but it was not in my budget. This has been a successful supplement, they feel better and I plan to keep them on it a few more months with hopes of getting them off the nsaids soon ( had laminitis from grass). They can be picky, but they ate it without complaints.

    Rated 5 out of 5 by from Just what we needed I had a weanling shipped to me, and after terrible weather and a much longer trip than usual, she arrived under the weather. It seems she had started an ulcer (not confirmed) from such a long journey. After a week of Ulcer meds, my vet recommended switching my filly to Smartgut Ultra. I called Smartpak, and of course they helped me with dosage, shipping, etc. It arrived in 2 days, and helped get my filly back to feeling terrific. Definitely recommend!

    Rated 5 out of 5 by from Winner Product! I've had my 5 year old Quarter mare on this supplement for one month and I am THRILLED with the results! She was grinding her teeth and showing sensitivity on her flanks, her underside, her complete tummy area since I got her in July (2015). Each time I touched her sides or tummy during grooming or tacking up she'd grind her teeth and threaten to bite or kick. Per my vet's suggestion, she had a month long course of omeprazole and a dental float. Then I added a month of SmartGut Pellets. She was still grinding her teeth and showing some sensitivity, although both were greatly reduced. Within a week of starting her on the SmartGut Ultra Pellets, the teeth grinding stopped!! And the sensitivity vanished! Thank you SmartPak! Thank you Supplement Wizard! We are both eternally grateful.

    Rated 5 out of 5 by from Turned my horse around My horse always loses weight in the winter, but this year has been the worst. He was losing interest in eating and wasn't finishing all of his feed. He had no fever, wasn't sick. One month ago I started feeding SmartGut Ultra. He has totally turned around. He's coming in for feed, eating every morsel in his tub and beginning to add weight. I am very glad I gave it a try.

    Rated 5 out of 5 by from All I can say is WOW!!!! I have been fighting with this for over a year. It presents as respiratory, with heaving, coughing and heavy wheezing (diagnoses heaves). Tried SmartBreathe which didn't work. Went through 2 courses of steroids and antibiotics, would clear up and then come back. Started watching him and noticed that when he got really bad he would pass gas and poop a lot and then feel better, like let's get up and canter better, so I tried SmartDigest thinking hindgut. Had a really bad episode while camping and once again after passing lots of gas and pooping A LOT, he was better. (he still always breathes a bit heavy at the heave line). Started reading up on ulcers and all the puzzle pieces seemed to move in place. Ordered SmartGut Ultra and within a day could see a huge improvement! A week and a half after starting it, we went for a ride and he ran into a very stressful situation which started him wheezing and breathing heavy but the difference this time was that instead of being out of commission until it all passed through him, he was fine in five minutes and we finished out our ride with him in "normal" condition. What a wonderful product! The only downfall is the price :( Worth it in the short term but expensive if he has to stay on this

    Rated 5 out of 5 by from Made the difference pharmaceuticals didn't! My coming 4 year old futurity prospect started acting off with the weather change; lying down much more than usual, and over the course of three days started looking at her sides, kicking her belly, classic colic signs. We treated with Banamine and she went back to herself the rest of the day. Next morning she was back down and acting depressed. Took her to the vet and received a diagnosis of Colitis and an upset stomach though no colic. Vet treated with antibiotics, kaopectin, Platinum Bio Sponge, and electrolytes and recommended small doses of banamine if she acted really off with continued antibiotics and Bio Sponge. Charlotte also had bad diahhrea. Two days later she was still staying away from the herd, not eating or drinking well, and depressed. I had some SmartGut that I hadn't opened yet, and started her on it. The next day she was back at the bale with the herd, and acting perky. It's been a week now and she is back to herself, and possibly even a little happier! She has always been a bossy mare and I see less crankiness in her now! Will be keeping her on this product for a very long time! Thank you Smartpak!
