Rated 1 out of 5 by from Smells great to me, but not to my horse Bought this for a gelding with stomach issues, it smells wonderful to me, but I guess not to him. He won’t touch it. Sad! I can’t recommend it, due to that my horse wouldn’t eat it.

Rated 5 out of 5 by from Smells Great We replaced another gut supplement for my OTTB because she wasn’t eating all over her dinner. She loves the way this tastes. It smells like lucky charms! It’s also made her much friendlier and less irritation around her belly!

Rated 4 out of 5 by from Amazing Product If Your Horse Will Eat It! My mare was diagnosed with Lyme disease and required weeks of antibiotic treatment. Even though she was receiving a regular daily probiotic through another supplement, I wanted to add another at the recommendation of my vet to help offset any potential GI upset. GUT was not only incredibly affordable for a two month supply (I bought the smaller container) but it also supplies a fantastic spectrum and quantity of pre- and probiotics. It's only drawback is that it's not terribly palatable. I had a rough time getting my mare to eat it in her grain and ultimately ended up mixing it with a little applesauce and syringing it into her for a majority of the container until we switched her to a forage-based diet that she loves. I am now able to feed this to her in her morning meal, but I had to introduce it slowly over the course of about five days. She is now eating it on her own no problem! Overall, I'm really happy with the results and am glad I purchased it, though, as she never had a single loose poop while on this and antibiotics, in fact I felt like her poop looked better than it did when she wasn't on antibiotics! Her treatment is now done, but I will use up the rest of the container to repopulate her GI flora. I would not hesitate to purchase this again and definitely think it's a great general GI support supplement.

Rated 3 out of 5 by from This would be great if my horse would eat it. She normally eats anything if its in grain but she isnt a fan. Im going to try the pellets or something else

Rated 5 out of 5 by from It Works. I've been feeding this product from a local supplier who is unable to get it in the 10lb canister so I will now be purchasing from SmarkPak. I'm thrilled to see this product is available in the powder and not the pellet as I prefer to not feed my horse the binding agents found in pellets.

Rated 5 out of 5 by from Helped my horse feel better quickly I bought this over a month ago after my trainer recommended it to give to my OTTB who has ulcers. I feel like he responded better to this supplement than he did being on prescription oral pastes. After just a couple days of adding this to his evening meal, he appeared happier, was more willing to work and even cribbed less! My wallet was pretty happy about the price too :)

Rated 1 out of 5 by from My horse wouldn’t go near his grain I decided to try this out & my horse, who eats any meds or supplements I’ve ever given him, wouldn’t touch his grain with this in it.

Rated 5 out of 5 by from Great Product for GUT issues My horse was having loose bowel movements, so I got GUT and it has solved her issue. I recommend this product to everyone who has a horse with this issue.
Date published: 2020-11-03
Rated 5 out of 5 by from AMAZING! Absolutely LOVE this stuff, however, like many others that I am seeing in the comments and questions... wish SmartPak carried the pelleted version. I took my horses off of SmartPaks and now order through ValleyVet autoship to get the products I need (including the pelleted version of this).

Rated 4 out of 5 by from May Effect Absorption of Other Drugs I bought this for my horse who has neurologic pain issues in addition to being ulcer prone. When I fed this with his pain meds it did seem to make his meds less effective, which at the time I was unaware was a possible effect. I had not looked closely enough at the container upon arrival as there is a Caution that it may slow down the process of absorption with some drugs listed on the back of the container. However is not listed or pictured on the information page so just wanted to call this out for others so they don't go through the trial and error we did. I do wish it had worked with his feed program as it did keep his gut happy the handful of days I used it before I figured out this was happening.

Rated 3 out of 5 by from Powder vs Pellets Forgot to check whether or not I was buying pellets vs powder.... Forgot Smartpak only has powder. GUT IS FABULOUS... but my horse absolutely REFUSES to eat the powder. Now stuck with it and have to go direct to maker to buy pellet.

Rated 5 out of 5 by from Wonderful product I've used this product on three mares who have responded very positively. They are much more relaxed and comfortable under saddle. Plus it smells good enough to eat!

Rated 5 out of 5 by from Amazing Product!! When we bought my mare, we decided to scope her suspecting ulcers. She had a very extreme case and had a full month of gastro guard treatment. As son as we finshed the treatment, we immediately moved her onto a loading dose of GUT and now she get (1) scoop per feeding. When the vet came to rescope her he was AMAZED at how well her stomach healed, said he normally doesn't see them get that much better especially in the amount of time. I love this product and will be keeping her on it through the show season to keep her stomach happy.

Rated 5 out of 5 by from Works great for my mare! My mare is 25 years old and moved to a new farm and was stressed out. I felt like she was internalizing her anxiety. Tried the G.U.T. She loved it and I believe it has helped transition her to the new place.

Rated 2 out of 5 by from Horse would not touch it I bought this a month ago and my horse that literally eats anything would not even touch it. It has a very weird smell to a horse. Almost like candy.

Rated 3 out of 5 by from Good product horrible shipping I love the product but have to stop using smartpack because they are incapable of using any other shipper the UPS who has a long long history of damaging, losing and delaying my packages so I cant do business with a business that cant ship USPS or Fed Ex I did contact customer service but they can do nothing

Rated 5 out of 5 by from Really helped my OTTB's comfort! I started my OTTB on this a few months ago and he has made so much improvement! He is no longer touchy about his belly, doesn't try to kick or bite during grooming sessions anymore, and just seems so much happier! This is definitely the best gastric supplement I've used and I definitely recommend it for those who are struggling with ulcers.

Rated 1 out of 5 by from Horse wouldn't eat it I was hoping to give this a try, but my mare wanted nothing to do with it. If you'r horse is picky, I wouldn't recommend this.

Rated 5 out of 5 by from Gracious Customer service I had ordered GUT in plenty of time, but ran out before receiving the new shipment. Apparently, Uckele had run out of the 2 pound size. A phone call also revealed it would be another week before the order could be filled. Upon learning I was out of the product, the representative graciously told me she would expedite a 2 pound can at no expense to me, which I should receive tomorrow. Thank you for such excellent service.

Rated 5 out of 5 by from Smells great, great for picky eaters. I had originally purchased this for my old gelding who had reoccurring ulcers to hopefully prevent them. This seemed to work, he didnt have another onset while on this but I had assumed I could get away with only using this temporarily. He was an extremely picky eater at the time but had no problems with this (it smells like marshmallows!). He has since passed away and I began using this on my new guy when he came to help prevent ulcers. He also eats it with no issues and his appetite has been fantastic despite the stress of moving barns. I would definitely recommend this, a great value for the price!
