    G.U.T. is rated 4.5 out of 5 by 139.
    Rated 5 out of 5 by from Liked the natural ingredients I have been using this going on 2'mo now and have seen much improvement in my mare. She is more comfortable and has a better attitude. So far this is helping better than other supplements I have tried. Is also very palatable.

    Rated 5 out of 5 by from Completely changed my boy! I have a 8 year old warmblood that is very dramatic about anything and everything. I have always believed in preventative supplementation...with that said when I came across GUT a few years ago I put my gelding on it, I got such good results with appetite energy and attitude I was super pleased. He stopped being so cranky about things and so dramatic. After a year or two I changed him over to another digestive supplement that claimed to be even better and literally in three days he changed back to the cranky drama queen I put him back on GUT and boom he was pleasant. Also it smells like my match green tea from starbucks!!! and he gobbles it up...and he is picky!

    Rated 5 out of 5 by from Really helped my grumpy baby Can't say enough good things about this. I bought a three year old AQHA/APHA gelding in January who did not transition well to his new home. We treated with omeprazole and he was on SmartGut Ultra for a few months. The results were moderate-enough to tell they helped but not enough to help with attitude problems and some spookiness. He always just seemed genuinely displeased to see people and he would get so angry over small things. I switched him to GUT at the end of April and he has completely transformed. He is no longer angry and displeased with everything and everyone and has a much better attitude overall. I did also switch him from SmartTranquility to Smart Calm Ultra. Because I did them at the same time I cannot contribute his changes solely to GUT but they are working so well I have no plans to switch him anytime soon. I do also treat him with omeprazole for shows and follow the regimen of half a tube a day for 2 days before, 1 tube a day during and half a tube a day for two days after. I don't want ulcers to ever be a thing that needs more than this so I'm extra cautious. Lots of alfalfa and electrolytes as well while away. I was initially concerned about the powder form but he gets DAC Bloom as well and has no issues with that and I've not seen him turn his nose up at this either. Thats probably not a testament to palatability as he eats pretty much everything but its certainly not so bad that he will turn it down. This is a great, economic alternative to some of the other things on the market and seems to work just as well if not better. Im glad to finally have the sweet natured, quiet horse I bought back :)

    Rated 5 out of 5 by from Great Ingredients at an Economical Price! I've had my OTTB on this supplement for a month now. I was weary at first because it's a powder and he's usually not too keen on consuming powder, plus he eats a pellet that isn't sticky, so powder doesn't sit well on his meals. I tried it anyway, and upon opening the smartpak, realized this would be easy to feed! It smells like a cocoa type mixture, very yummy, and my OTTB LICKS his dish clean. Something he's NEVER done over a powder before! I've noticed significant reduction in girthiness as well as some firming up of his chronically loose manure; something that even SmartDigest Ultra (which he's also on) hasn't done over the last 6 months. I decided to put my horse on this after doing a full 30 day treatment of Omeprazole for Ulcers, and didn't want to throw him back on an acid reducer, but rather something with a more comprehensive ability to soothe the stomach. This is that product!

    Rated 5 out of 5 by from Works well for digestive issues in horses. After having EPM, my horse had digestive issues and giving him GUT, helped a great deal. It's economical and palatable and has worked well for my horse.
    Date published: 2016-02-19
    Rated 4 out of 5 by from Good ingredients, highly palatable Honestly, my horse wasn't having obvious digestive issues but he has a history of chronic laminitis. I read that laminitis can be linked to improper digestion. So, I'm giving G.U.T. more or less as a preventative. I don't know if it is helping or not but it makes sense that probiotics would help. It smells great and my horse loves it. I'm hoping that this along with dietary controls will prevent a recurrence.

    Rated 3 out of 5 by from not sure about this I've had my horse one this supplement for about 3 weeks now. I'm not sure if it is really helping at all with the ulcer problem we seem to be having. He gets a scoop every AM, I may give AM and PM a try. He wasn't sure about eating it at first but now he gobbles it right up. The powder is so light that its very dusty if you shake up his grain to mix it in. It does smell like vanilla pudding, which is nice for me when i open the container! ha!

    Rated 1 out of 5 by from My horse's ulcers came back after a few months I added this to my horse's smartpaks to try to keep her ulcers from coming back after treating for 30 days with gastrogard. Well, a few months later, they were back, and I'm another $1000 out for another 30 days of gastrogard. No changes in training during that time, no shows, etc. Very bummed. I wanted to try something more affordable first but it cost me a lot more in the end. I'm going to try the Smartpak Ultra GI next.

    Rated 5 out of 5 by from Exactly what I was hoping for! I started my gelding on GUT a month ago and am so pleased with this product! He is quieter, more comfortable and less spooky. I would definitely recommend trying GUT

    Rated 5 out of 5 by from Seems to work! I've used this for over a month and I believe it's working great. My mare was not gaining weight, very picky eater and slightly girthy. I wanted something to help her gut with the stress of showing, training, and weight gain. She is no longer girthy, is eating all her grain and eats this supplement super!

    Rated 5 out of 5 by from Awesome product I bought this about 45 days ago for my seven year old ottb. He had an ulcer flare up, and would eat around the zantac and tums in his bin. He is a very picky eater, so I was worried he would eat around this too. I was wrong. He loves this. He even finishes his smarthoof supplements now, which he would previously eat around. He was on a loading dose of am and pm for thirty days, and now gets it once a day. He is a different horse. No longer surly to go forward, he actually tried to break into a canter today for no good reason! This is epic because when previously asked to canter, he would pin his ears and be very unhappy about the experience. He is a happy horse again thanks to this product. I highly recommend it for ulcer treatment and prevention.

    Rated 5 out of 5 by from Great product Has been working for my horse just fine. The powder sticks to any grain really well, it has a sweet smell like malt balls.

    Rated 5 out of 5 by from Works Well This is the best ulcer prevention supplement that I have tried. I like how comprehensive it is. I still also give my horse an antacid when he travels or goes through anything stressful just in case, but I didn't want to have to use an antacid all the time and this is a good daily alternative for prevention. It is also more palatable than I expected. I wasn't sure if he'd like it since it was a powder, but he eats it just fine.

    Rated 5 out of 5 by from Great ulcer prevention I used this on a very sensitive horse who had received Ulcer treatment 60 days prior. GUT really prevented further ulcer symptoms from coming back during our very busy show and traveling schedule.

    Rated 5 out of 5 by from Exactly what we needed!! My horse has been on this for two months now and i couldn't be happier. he is always anxious and nervous, especially in new situations, which makes him prone to ulcers. he used to buck and run like a colt every time i would tighten his girth, and just all around act unhappy but quite friendly. this stuff has just made him all around happier because his stomach isn't hurting anymore. i wish i had him scoped so i could physically show the difference!! its absolutely perfect and easily affordable. plus he is a SUPER picky eater especially with powder, and he just LICKS the feed tub clean!
    Date published: 2015-02-18
    Rated 4 out of 5 by from Awesome so far... I started my mare on GUT about six weeks ago. A little background so this review makes sense: I am a graduate student and I moved from my long-time barn in Madison, WI to a barn near the Twin Cities, in MN in September 2014. My OTTB mare was in fairly intense dressage training (~6 days a week) when we moved. She dropped a little weight (not surprised, OTTB after all) but after about two months at our new facility, her personality changed. She was wired, spooky, resisting contact under saddle. She was also getting more anxious on the ground. I chalked it up to incoming cold weather, etc. I had her adjusted with a chiropractor in mid-November, who noted that her back was sore. I knew it wasn't a saddle fit issue and I expected soreness from working her topline, but her musculature had grown immensely and it seemed unlikely it was just pure muscle soreness. Around this time I accepted a PhD position in Colorado, meaning another big move for my mare. Due to weather constraints, she was moved to a private boarding facility near Oshkosh, WI. She will move to CO in another 6 weeks. Knowing that I was moving her lot and that moving was hard on her (weight loss) I started to suspect ulcers. Coupled with the behavioral changes, I decided that something was 'off' with her digestive tract (even on a probiotic) and after some helpful research with SmartPak, chose GUT. Because I'm in CO and she's in WI, I can't attest to riding personality changes (hence four of five stars) but the managers at new facility said she's an absolute dream on the ground and was starting putting weight back on. It seems that GUT is helping her feel better and I feel better feeding it - hoping it will also ease her transition out to CO. It's worth the money if my girl is feeling better! Oh, and my mare is the PICKIEST eater and she's eats this right up!
