    G.U.T. is rated 4.5 out of 5 by 146.

    Rated 5 out of 5 by from Great price, works wonders! I bought this for my new, underweight gelding. He has been on this for about a month and is not only putting on weight but is chowing down his food like never before!

    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!

    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!

    Rated 5 out of 5 by from Economical for Gi Support I ordered this product to support my horse who has had a mysterious loose stool problem for the last six to nine mos. Was hoping to "cure" it with this product and if not at least support his gi system while we and the vet figure out what's going on.--gastric or hind-gut ulcers, or food allergy. I was looking for a product with L-glutamine and aloe vera that is not pelleted or liquid (winter feeding) and this fit the bill. My horse likes it, smells wonderful, and I soak his feed so the powder gets mixed in. There has been no dramatic change but his tummy seems a little more comfortable and have kept any potential colic at bay so far. One thing you must watch for is the licorice as it should not be used long term. This product can be used during times of stress to help prevent colics, ulcers, etc, so you don't have to use it everyday if your horse doesnt need it. I have switched to smart gut for the time being as it has more mgs of some of the ingrediants but no aloe vera. I do wish I could get that in a powder because now I am adding a small amount of alfalfa with the pellets which is one thing I know gives him the runs! The other thing i wish these products did not have would be the L. ascidiphyllous (sp.?) since he could have an overload of that in his system which is causing some of his problem to begin with. DoConsult a vet or a nutrition expert to verify my last sentence as that is just what I read somewhere.

    Rated 5 out of 5 by from Seeing Improvement I started G.U.T. about a month ago, but was skeptical that anything could calm my spooky horse, as I'd tried a LOT of other supplements. This one seems to be working. He's more focused and calmer, in just one month. He likes the taste too.

    Rated 5 out of 5 by from Great product! My mate has been on this for a couple months and it's working great. She also loves the taste and licks every corner of her feeder. Would recommend to anyone looking for an effective product.

    Rated 5 out of 5 by from Just what we needed I was feeding my horse another, more expensive supplement for ulcers and still needed to give him a couple of tubes of ulcer guard a month to keep him "maintained", but I knew he still wasn't really comfortable. I finally decided I couldn't afford to keep that up indefinitely, especially with minimal results, so I did some research and liked the ingredient combination in G.U.T. What a difference this change has made! Since starting him on G.U.T. 3 or 4 months ago I haven't had to give him any more ulcer guard. I'm saving over $100 a month, but even more important than that is I now have a comfortable, happy, healthy, eager to work horse. I wish I had tried G.U.T. months earlier. It is just what my horse needs.

    Rated 5 out of 5 by from Smells wonderful My horse was going through a crisis in our training regimen. My trainer mentioned I should look into digestive support for my horse. I did my research and chose GUT. His whole temperament has changed. He is moving forward and enjoying his job as a jumper! I definitely recommend GUT!

    Rated 4 out of 5 by from Might up to 5 stars if she continues to improve Rescue horse very stressed over food is calming down nicely. My guess was damaged gut from poor feeding practices and starvation. She gets 3 meals per day and a dose of G.U.T. with her other supplements (no grain, of course)

    Rated 4 out of 5 by from Did wonders for our nervous horse! My sister and I put her little rescue Arabian on GUT because the mare was very nervous with ulcer like symptoms. The mare has been on this for a few months now and WOW what a difference! It is a whole new horse! We went from a horse who always chomped at the bit and spooked at its own shadow to a mare that jumps even the scariest jump like a hunter! She is happy and relaxed! The only reason I rated it as a 4* was because she isnt a fan of the powder. She gobbled up the pellets!

    Rated 5 out of 5 by from Great Results! I have a filly who just turned 2 years old and noticed that she was eating some of my other mare's droppings like a new foal would. Although she was a good weight and eating well I thought she might need some pre or probiotics she didn't have so I ordered and started giving her G.U.T. Since then she has stopped her previous behavior and is developing beautifully!!

    Rated 4 out of 5 by from Horse loves the taste! My nervous nellie 24 y.o. QH gelding has been on G.U.T. for about 3 months. Vet suspected ulcers when he had two bouts of mild colic after what he (the horse) considered stressful events (like I said, a nervous nellie). Started him on G.U.T. based on discussion with vet, listing of active ingredients in the product and user reviews. I try to keep his environment low-key (he's out 24/7 with a run in shed next to his best girlfriend and has several ponies and miniature horses to harass over the fence line when he feels he needs to strut his stuff). So far - fingers crossed! - no further colic episodes.

    Rated 5 out of 5 by from Best Ulcer Supplement EVER This is the ONLY supplement I use for ulcers or suspected ulcer because it is the only one that WORKS and is also cost effective.  For mild cases, I used only G.U.T. and the ulcers always seem to heal.  For bad cases I use the G.U.T. after 30-60 days of UlcerGard.  This is the best ulcer supplement ever.  Recently I got a paint horse with a sour attitude that was a picky eater. 2 weeks of G.U.T. and he now eats anything and is the funniest, goofiest, most fun horse I've ever known.  G.U.T. saved his belly AND his brain!!!!
    Date published: 2013-12-05
    Rated 5 out of 5 by from Love this product Rescued a paint gelding that was about 200 lbs under weight, had ulcers and infested with worms. Once the worm problem was taken care of he gained maybe 100 lbs back but I couldn't keep any weight on him no matter how much he was fed- Grained morning and night with various weight boosters, grass for atleast 10 hours a day, free choice hay in the pasture and in his stall ( about 1/2 bale put into a hay rack every evening) most of the time he wouldn't even touch his hay and barely ate his grain- probably has a small stomach from being starved so long. Anyways after figuring out he more than likely had Ulcers, I just bought GUT to try it on him... WOW what a difference, complete difference horse from the night I started him on it to the next morning. He didn't act as if he was in much pain, after a few he started gaining weight and keeping weight on. Now he is happy and healthy. I tried switching to other digestive products and they don't work at all compared to this stuff. My horses don't even hesitate to eat it, just top dress it on their grain and everything is GONE! Would highly recommend it to anyone! Best part about it, its made/manufactured right here in the USA right here in my state too!

    Rated 5 out of 5 by from Complete 180 I suspected hind gut ulcers after much research and decided to try GUT to help. WOW!!! Complete 180 from my mare!! She's willing under saddle, friendly, and looks great too! It smells like marshmallows, she eats it right up! I do mix with some CocoSoya to help keep the powder on her food. I would recommend this to ANYONE who thought their horse might have ulcers.
    Date published: 2013-07-05
    Rated 5 out of 5 by from Awesome Product! I have had my horse on the product since I bought him 5 years ago. He had trouble gaining weight due to an ulcer. He hasn't had any gastric problems since I've him on it. It is very reasonably priced. An absolutely great value. You really get your money's worth from this product. And my horse, who is a very picky eater has never been unwilling to eat this product.
    Date published: 2013-07-03
    Rated 5 out of 5 by from amazing FIRST to the people who say this tastes like marshmellow, read the ingredients. the first one is marshmello roots -.- my horse gets chronic ulcers, so after treating him with omneprozeole i wanted to put him on something permanent. he is a super picky eater, but he gobbles this up. hours after i give it to him, he will always return to his bucket to lick it up. i have been using it for a month and the ulcers havent returned ( like before i started using this) i tasted it and it does taste like marshemllows. btw for those of you who are dealing with ulcers here are some of my suggestjions: i give this to him wtih 4 handfulls of safe choice (horses love it) and a handful of beet pulp. beet pulp is good because of the calcium. also give them as much straight alfalfa as possible, once again because of the calcium. Definaley buy this product, im going to order 4 more so i never run out!!! (the container lasts a long time, and iv been giving slightly over a scoop)
    Date published: 2013-05-24
    Rated 5 out of 5 by from Loved G.U.T! I had no issues with this product! My horse wolfed down his grain as usual. We have used have a lot of problems with cinchy-ness and general crankiness after I rode for extended amounts of time. Both of these issues cleared up in about two months of continued use of GUT. His coat is even shinier than ever. I would strongly recommend!

    Rated 5 out of 5 by from Great Supplement! I've added this supplement to two of my horses' feed (twice daily) during and after a 3-month ulcer treatment and it does a fantastic job of continuing healing, controlling stomach acid during stressful workouts/events, and addressing hind gut health. It is also has microbials, allowing me to discontinue a separate probiotic. For all that it addresses, it's a great value, and my horses enjoy the taste of both the pellets and the powder.

    Rated 4 out of 5 by from Great stuff, evntually I really like this product. It did take some getting used to for my mare. She didn't want to eat her food for a day or so, but after mixing it in at each feeding she got used to the smell and eats it happily. I used this product after she had been treated for ulcers for a month and then after the weaning off period. I wanted a little something to keep her belly happy, but not include antacid. So far so good!

    Rated 5 out of 5 by from Looks forward to eating it! This only came in a powder, so I was a little apprehensive at first. After one week of handfeeding it to my horse, he now laps his bucket clean. Loves the stuff. It smells like marshmallows. He was formerly treated for ulcers, and I wanted an affordable product with no antacids. I have had excellant success with this. He is happy, accepting my leg, and moving forward. His coat is shiny and he's holding his weight perfectly. Mouth quiet and working in bridle. What more can I say? He's always gonna have this in his SmartPak!

    Rated 5 out of 5 by from Huge Difference! At first my gelding didn't want to eat it but after only giving him the choice to eat the powder with the grain, he devoured it. Noticed a huge difference in him from time I got him to current time. More calm, digests food well and doesn't act like he is in pain. For the people whom cant get their horse to eat it, leave it out over night for them. I'd only give them the option of eating their grain with the powder mixed into it or just plain don't eat your grain for the next few days. I've tried U-guard powder and liquid, never noticed a difference in any of my horses. Also have tried cheapest stuff on market, this is the only one that seams too ease my horses.
