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.

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 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 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 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!

Rated 2 out of 5 by from Fussy mare would not eat it I tried introducing a little at a time, and she wanted no part of this supplement. Disappointed because of good reviews and price point.

Rated 5 out of 5 by from Great product My horse likes to eat this so it's easy to get into her. I feel it really helps soothe her stomach out.

Rated 4 out of 5 by from Less manure Bought this for my two senior horses, specifically for one who is very gassy and tends to show some anxiety. I especially like the herbal ingredients. I'm noticing less gas and both seem to be utilizing their feed better and have less manure. I have a super picky eater so I had to introduce this very gradually. It helps to wet his other supplements so the powder sticks and he eats all of it instead of being left at the bottom of his bucket.

Rated 5 out of 5 by from My picky eater loved it I bought this product for my gelding who has having all of the symptoms of ulcers. Within 10 days I noticed that his symptoms had started to go away, he was less irritable in his stall, ate his feed with no issues and was not sore when saddled. This product is amazing, plus it smells great and my finicky eater loves it.
Date published: 2019-05-26
Rated 3 out of 5 by from Horse loved it, but it didn't work for us I tried this for 2 months since the ingredients and price looked great. It did smell good and my gelding ate it right up, but it didn't help at all with his girthyness and poor attitude. I guess it just isn't what he needs. I am now trying something a little more pricey.
Date published: 2019-03-05
Rated 3 out of 5 by from Powder didn't work at all for my girls I was anxious to try this on my two mares because I am having to feed hay cubes at the moment due to a local shortage of quality hay, and they eat the cubes quickly then spend a lot of time standing around with nothing to nibble. Knowing that this can build stomach acid, I wanted something that would help soothe their bellies and hopefully prevent ulcers. This product has great reviews and despite several that say their horse refused to eat it, a lot more have said their horses eat it right up. I wasn't worried because my mares are not picky eaters at all and gobble their grain like it's a last meal. But I was shocked when both of them turned up their noses at their grain with this on it. Tried again the next day, same thing. They eventually ate it at some point during the night when they got hungry enough, but this isn't a great option in my mind, since they share a paddock and I want to know that they aren't eating each other's meals, which have different supplements in them. Long story short, I am going to try this again in the pelleted form (from another website), since I think this is a good product, I just wish Smartpak carried the pelleted form of this, and am now stuck with a bucket of powder that I can't really use.

Rated 4 out of 5 by from Love the supplement, BUT daily cost is misleading I bought the 10lb bucket in Feb, it's now mid Oct and I only have maybe 10 days left of it. Which means it lasted me roughly 250 days, not the advertised 302 days. I do not over fill the measuring scoop provided. I don't expect it to be exactly 302 days, but being off by 50 days seems really misleading. However, I'll keep buying because it works for my mare. I ran out for a couple weeks one time and she was noticeably less happy.

Rated 4 out of 5 by from Would recommend I started my gelding on this after being treated for ulcers with a daily paste. Seems to be working to prevent ulcers from returning. It’s always a plus when my picky eater will eat a powdered supplement- this one he approved of!

Rated 5 out of 5 by from I feel confident I feel confident I have done the best by my horse. He seems relaxed no comfortable now. And of course love the convenience of smart pal so I never wonder if or how much of his supplement he got

Rated 5 out of 5 by from Definite improvement I've had my OTTB gelding on this for a couple months now and I have seen a noticeable improvement in his demeanor. I've been through a number of stomach supplements and ulcer treatments with him as he has always been girthy and generally unhappy tacking up, and sometimes cranky under saddle. For the four years I've owned him, he would always grind his teeth the minute you set a saddle pad on his back, swishing his tail, even before you tighten the girth. Did a course of GastroGard, but nothing offered lasting results. Now, two months in with daily use of G.U.T., the tooth grinding and anxiousness are virtually gone. He is a different horse on the ground. Riding he is much more relaxed, no crow hopping or tail swishing. We had zero issues with palatability; his grain is always soaked so it mixes in well and he eats it willingly. I have also started giving him a small scoop of hay pellets with about a 1/3 scoop of G.U.T. to munch on while tacking up before our rides just to settle his stomach. I think it's definitely made the difference in our workouts. He is happy and more relaxed in work now. Add to it the bonus that it's not as pricey as some of the other supplements I tried that made no difference whatsoever.

Rated 5 out of 5 by from Great product After trying several digestive products I finally found one that works. My mare hasn’t had diarrhea since started on GUT.
Date published: 2018-01-31
Rated 5 out of 5 by from Wonderful Alternative Fair warning, this powder smells like hot cocoa mix, and I was worried my horse wouldn't eat it, but, he licks his tub clean every day. So far I am loving this supplement, and I think my gelding is as well. I turned to this product after searching for an alternative to a much more expensive product that had similar ingredients, to help with digestive issues and to hopefully prevent ulcers. My horse had started to get really grumpy whenever I did anything around his gut, including girthing him. I haven't really been able to see if the girthiness has improved since winters mean little to no riding for us as I have no indoor to ride in and lots of snow. Hoping I might see a difference in the next few weeks as I get back to riding.
