good insurance for nightime feed

The barn manager recommended it and swears by it for horses prone to colic. I also saw supporting research. I like the pellet since my horse is finicky. He seems to like it. Using this helps save me work from having to add mineral oil to his meals.

a great gut tamer for training and anxious show horses.

My horses seem to like the taste of these pellets and I want to help protect them from ulcers and colic. Preventative maintenance!!!
DONNA H on Jul 16, 2016
I've used this several times over the years and have noticed differences within days. My gelding was losing weight and getting girthy and sensitive when grooming his stomach. Put him on this and he is gaining weight again and is no longer girthy. Would recommend this for maintenance and gut health.

Seems to offer pretty good protection for my TBs delicate stomach issues

Purchased hoping to cut back on ulcerguard; seems to help and is palatable.

Vet recommended and seems to be working well for my horse.
Bridget M on Jul 10, 2015
This has really helped my OTTB! Great product! He is gaining weight and has a much better temperament. I didn't know ulcers could cause such pain in horses. I am so glad to have found this. If I go to shows I double the amount in his am and pm grain and then on top I take a few tubes of Ulcer guard paste with me to shows to ensure that he is comfortable. works great!!!!

Recommended by a friend who has had good results using it.

Keeps my mare's tummy very happy!
SHARON B on Sep 26, 2014
I have a nervous animal that is always too thin. The reviews that I read described animals that were having the same issues as my horse and they had success with this product. I'll try it and see if it works for me.
Jannette C on Sep 3, 2014
Horse had ulcers
Nancie S on Aug 18, 2014
I love this product! We had a horse that would rear and paw when tied to the trailer and would tend to get a bit nervous while waiting to go into the show ring. After reading some reviews on the product, I decided to give it a try. It has worked WONDERS. So glad I didn't go the really expensive route that other show people did.

Needed for joint supplement
JOANNE W on Jul 15, 2014
recommended by a friend. My horse was always irritable before I started using this product. Now he is much more pleasant and a lot more comfortable. Works wonders for horses with ulcers!!
ANGIE H on Jun 21, 2014
This is strictly a trial run. My local feed store in Alaska does not carry the product. One of my horses has ulcers, which has made her un-ridable. I want to see if this product will help her to the point of getting back under saddle.
CECIL P on Jun 17, 2014
works great for my 2 older horses
JEANETTE G on May 27, 2014

When Budley doesn't get this, I am paying for a vet bill. I guess he has a very sensitive tummy.

I had a horse that would sometimes just collapse during riding at competitions & was a little nervous. After starting this U-Gard I never had that problem again!

U-Gard works for equine ulcers. I have had my stallion on it for approximately 8 years. Prior to that time he had regular bouts of colic because of his ulcers.

How many feedings do u get in this container?
A shopper on Jun 25, 2016
BEST ANSWER: It last about a month. I no longer feed because it didn't work. When I had our mare scoped after being on this she was still stage three with ulcers. So vet recommended using Ranitidine .We started feeding this as per vet instructions and after 28 DAYS on this we had her scoped again and they were all healing. Now we only give Ranitidine a couple days before a competition and a couple days after. Not expensive either and your vet can call it in to your Pharmacy.
Can you feed this to a horse who has ulcers already?
Cheyenne N on Apr 12, 2016
BEST ANSWER: i'm sure it's OK. But the way to cure ulcers is to buy the generic brand of acid reducer that starts with a P. I don't remember which, but it is the one with little pellets in capsules, not the tablets. It was something like 10 pellets a day for 7 days. Empty the capsules into the horse's food. The capsules come in 3-packs, and I think I bought 3 and had 2 bottles left over. It costs a fraction of the prescription horse version. A friend said her vet told her about it. It worked.
I only feed grain once a day. Can I put the recommended amount (2 oz) in that one feeding?
Holly N on Nov 18, 2015
BEST ANSWER: I have done that and it works, but I have a gelding who is a stress case that does better twice a day. In the morning I just give it to him with a handful of grain and he cleans it up.
how long does it take u guard to work?
A shopper on Apr 6, 2015
BEST ANSWER: Years ago, I actually started with a paste product and then heard about U-Gard. I decided to try it and it is great!!! I have used it ever since for my stallion. I can't actually say how long it should take to work, but it has seemed to work right away. I did stop the paste product as soon as I started U-Gard with no breaks and he did not have an episode in between the changeover. I now use it for two mares that are on daily pain medicine to keep them from developing ulcers. I gave it to my sister for her dog that had stomach problems and she is now using it daily for two of her dogs because they are on joint medication. My daughter is doing the same. My stallion suffered for years with colic. In 2006 he had a extreme colic episode. All the local vets said he was surgical because of his history even though they had not examined him. I called an animal hospital in Kentucky to see if they could do the surgery even though we were going to have to borrow the money. I just happened to talk to a vet named Dr. Carol (I haven't found her since). She actually LISTENED to me and asked me questions about his symptoms. She said it sounded like equine ulcers and told me how to diagnose it. SHE SAVED MY BOY'S LIFE THAT DAY WITHOUT EVER LAYING EYES ON HIM!!!!! I will never be able to thank her enough. The U-Gard has done its job since.
Will u-gard pellets help with a horse that has extra fecal water when passing manure?
A shopper on Feb 27, 2015
BEST ANSWER: U-Gard is formulated for the prevention and treatment of gastric ulcers. Please consult with your horse's veterinarian about your concern for the manure.
