Rated 5 out of 5 by from Helped my guy enjoy his grain again! After figuring out my gelding had ulcers I decided to give this a try. It has worked wonders. He now is back to eating and back in the ring! I'm now on my third bucket!

Rated 3 out of 5 by from It’s ok Seemed to work ok, but I wouldn’t get the powder again. It practically explodes opening it and my horse didn’t seem to like it in his grain. He would snort and it would just go everywhere. He ate it though.

Rated 5 out of 5 by from U-Gard I bought this a month ago and so happy I did. It is so convenient to have it in a SmartPak pack.

Rated 5 out of 5 by from Works great for our horse! Our horse has. Long time history of ulcers and the maintenance dose each day staves off the ulcers!

Rated 5 out of 5 by from Great for Maintenance!! A really good supplement for my mare, will always feed it. She stayed happy and healthy from the switch of 24 hour pasture to dry lot/stall, unlike my old gelding who had ulcers. Calypso also enjoys the taste- always goes for the grain with this stuff on it first! My personal favorite is the larger bucket, because it is easy to open and close when feeding unlike twist tops and has lasted way over 2 months.

Rated 5 out of 5 by from Worked Great!!! I bought UGard to help with the maintenance of TJ’s ulcers. At first she wasn’t sure of the powder, but grew to eat it with her grain. She is a happy girl right now.

Rated 4 out of 5 by from Peace of Mind I put my senior on this because he's had to have high daily doses of bute lately for his ringbone, and I wanted some assurance that I was protecting his stomach against possible irritation and ulcers. This seems pretty palatable--he eats it top dressed on his grain each morning and doesn't complain. Not sure if it's having the desired effect on his stomach, but so far so good!

Rated 1 out of 5 by from Horse wouldn't eat it Can't tell if it would help his ulcers or not because he wouldn't eat it.

Rated 5 out of 5 by from Ugard is great! I use Ugard in my ulcer prone horse's pre-ride alfalfa snack to help keep the stomach acidity down during my ride. It makes a noticeable difference in her comfort level which helps make us have productive rides.
Date published: 2017-06-20
Rated 5 out of 5 by from Awesome product Absolutely love U-Gard! I noticed a difference in my horse's behavior a couple weeks into using this product. Much calmer, less wood chewing, less agitated during grooming. I highly recommend this product if you suspect your horse may have, or be prone to, ulcers.

Rated 2 out of 5 by from My Horse does not seem to like it. I think it might be that the powder does not dissolve very quickly. it also seems to become thicker. need to use a lot of water.

Rated 5 out of 5 by from U-Guard gaststric aid My horse has issues and I need to bag alot of supplements with pills. She is a senior horse and this is a supplement I have considered to keep her digestive system heathy. I'm glad U-Guard comes powder form to bag along with the other supplements. An SAA test was just taken and results came back fine. I will be keeping my horse on it.

Rated 5 out of 5 by from Super colic and ulcer profuct I heard this might help horses with undiagnosed colic issues and cribbing. I tried it and I'm 1 day my horse cribbing reduced to almost nothing and he is back on his feed. And watching still for colic reduction. We were unable to check for ulcers which I suspected were colic cause but the uguard has made dramatic improvement in horses overall conditions. Great product.

Rated 4 out of 5 by from Love it! My mare is uptight and very girthy so my trainer suggest an ulcer supplement. I got the pellets and am almost done with my first months supply. Surprisingly I am noticing subtle differences; more shine in her coat and less ridged when I ride her and her little forelock is growing out more than usual. I am impressed and am purchasing the powder form this time (I got the pellets but they were more expensive and didn't last as long for the price).
Date published: 2017-02-15
Rated 5 out of 5 by from Great product I am happy with the results I have gotten from putting my horse on this supplement.
Date published: 2017-02-02
Rated 4 out of 5 by from Decent product. I like the ingredients in this supplement. And my horses did eat it. My only issue is it's so messy and hard to mix - not the best powdered supplement I've used. I tried both water and oil, but either way it's messy and stuck more to the bucket than the grain. So I'm switching to the pelleted form of the same product, as I do think it's a quality supplement.

Rated 5 out of 5 by from Helps anxious ulcer-ey horses Put my gelding on this about a year ago and within the first few months he stopped cribbing and there was a definite change in his demeanour. Smartpaks make it so much easier!
Date published: 2016-12-28
Rated 5 out of 5 by from Very easy! My horse ate it in his feed with no problem! Put weight on his top line and filled out in the rib area. LOVE this product.

Rated 4 out of 5 by from Helped with crabbiness I bought it originally to try to stop my bad cribber. I haven't really noticed a difference in his cribbing. But he does normally get crabbier as the cooler weather moves in and so far has been quite pleasant. I do believe it has helped him be less crabby and so I am happy I put him on it just in time for fall and winter!

Rated 4 out of 5 by from Decreased Diarrhea! I tried the Smart Gut ultra and had no luck for my 2 sensitive stomach horses. I switched to the less expensive U-Gard and my boys are feeling much better!
Date published: 2016-08-30
Rated 5 out of 5 by from WORKED FOR DREAMER! My farrier worked with a veterinarian and believed my horse was "girthy" due to stomach ulcers. She also touched a pressure point that my horse responded to that would be another indicator. After taking U-Gard she has shown improvement for certain.
Date published: 2016-08-17
Rated 4 out of 5 by from Bought this to ease ulcer pain Im still not sure if its helping or not, but my gelding loves the taste of this powder mixed with his pellets!

Rated 5 out of 5 by from Love It! My hot barrel horse suffers from ulcers, and after using this product she has gained weight, calmed down, and is overall more happy than she has ever been. I would highly recommend this product.
Date published: 2016-05-18
Rated 5 out of 5 by from A+ My dressage mare has always struggles with weight and ulcers. After treating her ulcers with Succeed, we continued with U-gard during the hard keeping show season and summers, where she tends to get an ouchy stomach. After some time off over the winter, I restarted her on U-gard and immediately noticed an improvement in her appetite, attitude, and overall gastric health. It's definitely my go to supplement for her sensitive, easily stressed out stomach. Helps keep her preforming at her best during show seasons and intense training. My only negative is the powder is very messy and sometimes difficult to mix unless with soaked beets or something else to stick to.

Rated 3 out of 5 by from Maybe it needs more time... I tried this on a bit of a whim because I suspect my TB may have some GI issues. He's getting scoped in June, but I figured it wouldn't get to try UGard for a month. It was within my price point, and the reciews were ok. I got the loading dose and was giving it twice daily, as suggested, but really didn't notice much of a change in his girthiness or irritability. I decided to switch off after a month and try a two week sample of Redmond GoldSupreme, which is touted to have similar results. After a week he was not grunting when I was brushing his belly. I'm not 100% sure whether it was coincidental or not. Maybe I'll give UGard another longer trial in the future, but one month didn't cut it for me. Also, it is very powdery! A lot stuck to the feed bin and was left behind....
