    Rated 5 out of 5 by from Awesome product I love Smart Gut Ultra. I first used it over a year ago. My picky eater of a horse was showing symptoms of ulcers. I started him on Smart Gut Ultra and within a week he began to enjoy eating again. Also as a bonus, he became less of a hard keeper. Since then, I've put 6 other horses on it and they have all flourished. Smart Gut Ultra has become my go to supplement for my horses. Thank you SmartPak!

    Rated 5 out of 5 by from seems to work I started my older gelding on ulcer supplements due to herd bound issues,anxiety, and occasional gas colic. He is more comfortable and relaxed. Probably the magnesium is a big factor. He eats it greedily. It seems this has made a difference.

    Rated 5 out of 5 by from Works like Ulcerguard My horse gets tummy trouble every time he has minor episodes of pain - a shoeing issue; his saddle needs adjusting; he gets vaccinations - well you get the picture. He's a sensitive guy. Sometimes it takes me a bit of time to sort out where he is uncomfortable and by then he's gassy and showing several signs of an ulcer. He has scoped positive in the past. He gets Smart Gut Ultra Pellets every day - 2 scoop. One time when he was showing signs of an ulcer, I decided to double up on his Smart Pak and found within a week he was fine. Since then I keep a 5 lb. of SmartGut on hand and if we hit a rough patch, I add an extra scoop each day. I have not had to use Ulcerguard in a long time.

    Rated 5 out of 5 by from Works for my ulcer-y gelding I treated my horse for ulcers and was using enteric-coated omeprazole granules as a preventive for 2+ years. Expensive, but waaay less than GastroGard or UlcerGard. When there was a hiccup in shipping the granules, I had to find something else. After much online research, I chose SmartGut Ultra -- it was the only product that had research to back up the claim that it prevented the rebound effect of taking a horse off omeprazole. It's been 18 months now and it's working great. No problems with palatability at all and no ulcer-yness whatsoever.

    Rated 5 out of 5 by from Love this My mare had grade 3 ulcers and after healing them my vet recommended the SmartGut Ultra. She is doing so well no with no sign of the ulcers returning! It is on the expensive side but it's well worth the money!

    Rated 2 out of 5 by from Didn't work but very palatable My horse stopped eating grain and hay when he was moved to a new barn so I treated with omeprazole for a month weaned him into 1/4 dose and started feeding smartgut ultra and stopped omeprazole after three days. Seven- eight days of just smartgut ultra, no omeprazole, and he went off grain and hay again after coming home from a trail ride over to his old barn. the anorexia wasn't as bad as 6wks ago but I'm back treating with omeprazole and disappointed the smartgut ultra didn't work well enough. He liked the taste until the day he went off grain again

    Rated 5 out of 5 by from Keeping my horse comfortable! I ordered this product after consulting your very knowledgeable person as a follow up to prescription treatment for ulcers. There has been no recurrence of signs of discomfort and the horse has returned to his former happy disposition prior to diagnosis and treatment. I plan to continue using this product. Smart Pak wins again!

    Rated 5 out of 5 by from Great product I bought this for my horse who became girthy and very very spooky. He had never been like this before. I wanted an ulcer medication, but I wasn't sure what would be easiest. These smartpaks are so easy, and the medicine works great! I have my horse back, and he has been doing phenomenal.

    Date published: 2017-03-03
    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!
    Date published: 2016-11-29
    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.
