Product Overview

Which horses benefit from comprehensive gastric support?

Your horse was designed to consume small amounts of forage throughout the day, so his stomach produces acid 24/7. In a natural grazing situation, where a horse is chewing and swallowing consistently, his gastric acid is buffered by forage and saliva. This buffering action helps keep excess acidity from damaging the sensitive stomach lining. Unfortunately, many common elements of modern horse keeping – such as training, travel, increased stall time, and feeding practices, like large grain meals – are often at odds with how horses were designed to live and eat, which can lead to gastric upset. A stressed stomach can negatively impact your horse’s health, attitude, and performance, which is why providing a selection of ingredients that support gastric health is a smart way to help him look and feel his best.

SmartGut® Ultra Pellets is rated 4.7 out of 5 by 266.
Rated 4 out of 5 by from Great featured Upon recommendation of my trainer, my mare is on her second month of this product. Based on the excellent assistance of a SmartPak representative, review of the product and my trainer's endorsement; hopefully it will be another of my mare's supplementsls.

Rated 5 out of 5 by from Veterinarian recommended My horse is doing well on SmartGut Ultra pellets. My Veterinarians had recommended this product after diagnosis of ulcers. After our initial medication treatments, SmartGut Ultra has helped my horse feel his best. I am happy with SmartPak products.

Rated 5 out of 5 by from Great support for my ulcer prone horse I had my mare on SmartGut for prevention after she had some pyloric ulcers a year and a half ago. She still gets ulcery with changes such as the new arena being put in (trucks coming and going next to the paddocks), herd changes, etc. I wanted to see if switching to SmartGut Ultra would improve her tummy issues. She has been so much more relaxed with the switch. The trucks have been coming and going again, bringing new footing in and she doesn't even look. Part of her herd left for a show and it's not a big deal this time. She still has the same energy and curiosity, just not the typical signs of an upset GI that she normally might get with these changes.

Rated 5 out of 5 by from Happy Mare! My mare has always been a little nervous. We have been showing ARHA quite a bit this past two summers and she was showing beginning signs of gastric distress. (Not eating well at home and on the road, grouchy, etc.) This product has helped her tummy chill out, she is eating great at home and on the road, and back to her wonderful sweet self. Thanks SP for making a easy to use, effective, and palatable product!

Rated 5 out of 5 by from SmartGut® Ultra Pellets works great I started our young horse on SmartGut® Ultra Pellets to protect his gut while starting his training. I notice he stays calm and seems more focused. I love this supplement and will keep him on it forever. I think gut issues happen a lot in horses that act up and owners don't realize it. I highly recommend this product!

Rated 5 out of 5 by from Works! My 4yo ottb was scoped by my vet and diagnosed with grade 1 ulcers after suddenly becoming quite difficult (and that's putting it nicely) in training and just being grumpy in general which is not typical for his personality. I treated with omeprazole and stated him in one Smartgut Ultra. Wow! He's now so comfortable, willing, and back to his sweet self!! I always want to make sure all my horses have the support they need and Smartpaks is where I turn for effective supplements.

Rated 5 out of 5 by from Does what it says it's supposed to do My very pron ulcer barrel horse has been on these for about a month now. I see a huge difference with her. I'll know even more once she goes back to full competition. As of right now they do what it says it's supposed to do... protect the lining of the stomach from creating ulcers. She seems so happy and energetic, so I feel they are doing the job. I'm also an equine vet tech and all the vets I work with (5) recommend this product to help protect.

Rated 1 out of 5 by from Didn’t work I’ve been using for 2 months and my gelding has another bout of colic. I don’t feel it worked at all.

Rated 5 out of 5 by from Passed the taste test!! My horse is happy to eat the Ultra pellets! And his tummy is happy!

Rated 5 out of 5 by from Miracle worker for suspected ulcers I have a 5 y/o dressage horse and noticed he was increasingly girthy and irritable after moving him across the US and living through the PNW wildfires, including evacuation from his farm! I was 100% sure this induced ulcers so I put him on this for a month and after 2 weeks he was back to his plucky self. He eats anything in front of him (including hoof picks, gloves, plastic, etc) so I can't say much on palatability, but this was 100% worth the money.
