GUT™ Powder is rated 4.4 out of 5 by 186.
Rated 5 out of 5 by from GUT Slurpee I mix a scoup of GUT with two handfuls of compressed hat and 2 oz of Flaxseed oil. Add water, stir, let set for about 15 minutes to let the hay absorb the water. My mare LOVES her daily slurpee and her ulcers have resolved.

Rated 3 out of 5 by from Disappointed I bought this a couple of weeks ago. My horse refuses to eat it, even when mixed with lots of applesauce. I have been mixing a scoop with either water or applesauce and giving it by syringe. It is messy and difficult, but it seemed to help, as poo was firmer. I will look for another product, as syringing thick liquids in winter temps in not sustainable.

Rated 5 out of 5 by from So good so far! Just started feeding this about a week ago. He completed treatment for ulcers and I'm using this product to support his gut health. He is a very picky eater, so with every new supplement we start with very small amounts added to his grain and slowly increase the amount over a week. Yesterday was the first full dose and he gobbled it right up! I am relieved after reading some reviews that some horses won't eat it. You could also mix it with applesauce or molasses if you run into this issue and slowly decrease the amount. I will update this review later on after next year's gastroscopy.

Rated 3 out of 5 by from My horse would not eat it. My newest horse will not eat it. She is a very food driven horse and is the first one to her stall at feed time; however, she would not touch her food with this in it. I know it works because one of my older horses had great success with it years ago; however, it is a waste of money if you have one that will not eat it.

Rated 5 out of 5 by from Horses like the flavor - seems to work! I ended up putting all my horses on GUT after my OTTB was on it for a few months by herself. She became less girthy, less uppity about grooming her abdomen area, just in a better mood it seems. So the youngster to the oldster - all get a scoop every day.

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
