    Rated 5 out of 5 by from Success! I started my horse on this two weeks ago. He was treated for ulcers three months ago, but he started biting the cross ties and acting up again when his belly was groomed this month. I decided to put him on a supp to manage what appears to be a reoccurring problem. The first week was hard to tell since we had severe weather but now? I curried his belly today and he dozed. My horse is not at all picky (he's a hoover) so him eating every bit is not much of a measure, but there you go. Yes, it's a spendy supp, but I'm happy to pay it in exchange for his calm, happy demeanor when I handle him. Should be a life saver when the show season starts up again and he's on the road. I like feeling like I'm being proactive keeping him comfortable.

    Rated 5 out of 5 by from Made a huge difference for my horse My horse was treated for ulcers about a year ago, and started showing symptoms again, not wanting to eat, tense and nervous under saddle, dropping weight. I will be treating him again, but needed something to make him more comfortable while I come up with the funds. I started him on this supplement and within a couple of days he was back to finishing all his grain, and much happier under saddle. After a few weeks his weight was back up. I am beyond thrilled with the results!

    Rated 5 out of 5 by from My horse loves this product I have been purchasing this product since my vet first gave me a free one month container. My horse has ulcers from neglect from his previous owner. This is my 2nd automatic delivery of this product. I plan to keep him on it for the rest of his life. He is 18 years old and has been doing 100times better since my vet gave us this product.

    Rated 5 out of 5 by from After treating a 19 year old retired gelding for pyloric ulcers I made the decision to do preventive therapy for him. After an extensive literature review in the peer-reviewed veterinarian journals, I selected SmartGut Ultra. To-date he has been ulcer free!

    Rated 5 out of 5 by from Great results! I started my horse on Smartgut ultra after being scoped and finding grade 4 ulcers. I was thrilled when after his 28th day check on treatment of gastrogard we could begin weaning him off treatment as his ulcers were nearly fully healed. I definitely believe Smartgut ultra played a huge role in making him more comfortable during treatment.

    Rated 5 out of 5 by from My guy finally is filling out. I bought this for a rescue I got in May. He came to me very thin, pretty lame, colicky, cribbing after every meal and he had signs of having been on painkillers/meds for some time. I suspected (due to scars, symptoms) that he had had some injuries that kept him stall bound and on meds for a good part of his recent years and likely suffered gastric issues from that. After 2 months of 24 hour pasture/turn out and good feed, he still seemed uncomfortable, cribbed and wouldn't fill out, especially in the rear and top line. After just 3 weeks on SmartGut, he looks great! His hind end has filled in, and his spine is far less prominent. He is also much better tempered and LOVES his food. The cribbing still happens, but far less and only after feed times & if he has access to something he can grab with his teeth- otherwise he doesn't bother. I highly recommend this product for anyone with older, thin horses just to help them out.

    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 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 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!
