UlcerGard is rated 4.8 out of 5 by 247.
Rated 5 out of 5 by from Beat ulcer prevention This is the best ulcer prevention for hauling and competition. I like to dose my horse leading up to any hauling events, and I found the most competitive prices at Santa Cruz.

Rated 5 out of 5 by from A great over the counter product! [This review was collected as part of a promotion.] A fantastic product for keeping my horse's stomach happy at shows and ready to go at all times.

Rated 5 out of 5 by from IT WORKS!! I recently bought this for my 14 yr old quarter horse gelding due to him noting eating and was just grumpy. He usually has bug eyes and ears forward. He gets picked on in the pasture and recently had a new one added that acts like a stepbrother. Gave him a full tub and wow! I wasn't sure if it was ulcers because he's not cinchy and doesn't act like a typical ulcer horse. He was trotting around and rearing up on horses picking on him, which he never does. He started eating again and he doesn't look stress/ grumpy anymore. Will definitely continue treating with this and always have it handy.

Rated 5 out of 5 by from LOVE IT we have a chestnut American Saddlebred Gelding 9yr old that is a rescue who just seems to be having some issues. weather, feed, living change has caused ulcers to rise. did 6 days doses for him and there has been a major different in him. seems to be picking up weight a little more. Our Bay Mustang/TB 10 yr also got the 6 day doses. He is a mean grumpy man! some of it is natural but he was a bit of a brat with us and became very cinchy. He is so much more calm now and level headed. cant wait to ride him and see how much better he did. however I ended up buying 6 tubes not realizing 1 tube is 4 doses. so I now have 3 tubes left over. it is very pricey but it seems to be doing really good. its been a while since I have seen him be extremely loving and I am glad to have that side of him back.

Rated 5 out of 5 by from Amazing product I’ve had to use this recently as well As in the past. Ulcergard is beyond amazing for active ulcers. Smartpak does an amazing job of keeping the price low which is a huge help!!

Rated 5 out of 5 by from Precise for its function I bought this recently to have on hand for long hauling days. My girl has been having anxiety on eight hour travel days and I want to take care of her stomach.

Rated 3 out of 5 by from Works but Expensive [This review was collected as part of a promotion.] When it comes to protecting or healing foregut ulcers, this product works. Unfortunately, it is extremely expensive, especially if a horse requires more than the 1/4-tube maintenance dose.

Rated 5 out of 5 by from Love this product [This review was collected as part of a promotion.] My horse seems so much happier, less crankiness and more comfortable

Rated 5 out of 5 by from Works like a charm After two weeks I see a noticeable behavioral difference in my mare after a stressful transition to a new barn.

Rated 5 out of 5 by from I purchased this to have on hand "just in case" as I like to be prepared. Stress, shipping, stall confinement, etc. can all lead to gastric ulcers. This is the only FDA approved drug that can be used to prevent gastric ulcers in horses, so I feel better knowing I have it in my equine medicine cabinet.
Date published: 2020-11-21
Rated 5 out of 5 by from Works Awesome product that works. Highly recommend if you horse needs treatment for ulcers or preventive measures of gastric ulcers

Rated 5 out of 5 by from Great product with proven results! I give my horses UlcerGard prior to shows and while they are at shows. It helps my horses stay comfortable under the stress of showing.

Rated 5 out of 5 by from Completely different horse! My Saddle Seat Horse went off her grain. Still eating hay and grass but would not Eat her grain and supplements. After talking to my vet he recommended I start her on this in hopes that what she had was just ulcers and it was not something more serious. since my horse has been being a complete brat well riding (which was not completely uncommon for her) and she goes to shows every weekend. We figured ulcers were the most likely cause. Wow big difference she has started eating again and has stopped spinning and rearing during training. Can’t believe the difference! The only down fall is how expensive it is for someone like me who is not making money off of showing. I got it from my vet so it was even more expensive. But he took a good amount of time to help me out so I got it from him. But I will definitely be getting it from here in the future!

Rated 5 out of 5 by from My trainer recommended that I give this to my Ottb, she just came off the track a year ago. She is being very angry/uncomfortable about being cinched up etc. my mare loved it and tried to eat the tube. Smelled like cinnamon.

Rated 5 out of 5 by from Really helps My 29 year old quarter horse suffers from occasional ulcer problems. UlcerGard has helped him before and did not let me down this time either. He is perking back up and feeling better.
Date published: 2020-01-08
Rated 4 out of 5 by from It works, but a bit pricy This product definately works if your horse has ulcer, or early stage stomach issue. But it is pricy. And dosing instruction can be bet better. Make it simpler. My friend was using it but in the wrong dosing! It's easy to misunderstand. Maybe smartpak can give suggestion?
Date published: 2020-01-01
Rated 5 out of 5 by from Peace of mind I use ulcerguard when hauling and competing even though my horse does not have ulcers. One dose per day gives me peace of mind that I’m doing all I can to help keep stressful situations comfortable for my horses!

Rated 5 out of 5 by from Great product When I bought my horse 15 months ago and moved her to a new boarding facility she developed GI ulcers. I needed to move again so I started Ulcerguard several days prior to moving my mare to her new stable. She went from no grass to full grass pasture so I was worried. We did a slow grass introduction over 2 weeks. She transitioned and no GI issues this time thanks to Ulcerguard.
Date published: 2019-06-24
Rated 5 out of 5 by from Works great! [This review was collected as part of a promotion.] I have used UlcerGard to treat and prevent ulcers on a mare that was naturally very nervous and prone to ulcers. I saw improvement within the first week of treatment. Although it may be pricey to use as treatment, it is effective and worth the money!

Rated 5 out of 5 by from SmartPak was great to work with as always! The vet ended up being unable to order IM omeprazole for me (back ordered for weeks) so i ended up in a pinch needing this quickly and having no local options to pick some up (i'd already bought it all LOL). SmartPak made it happen and got it to me just in time! So glad this company is so great to work with, and offers one of the best prices available for this product unless you're buying huge quantities. The ONLY negative thing I'll say is that the packaging for the 6-pack is a bit wasteful - just 6 individually packaged boxes inside a larger box. But perhpas that's the only way Merial produces them?

Rated 5 out of 5 by from Who wants to deal with ulcers? Every now and then, I have to give my gelding a dose or two of an NSAID. When I do, I always make sure I have some Ulcergard on board. Who wants to deal with ulcers? I know I can rely on Ulcergard to deliver the right dose of omeprazole to help keep ulcers away. And it's really easy to add a tube or two to my Smartpak autoship!
