Put my horse on this 1 month ago. He has put on so much weight. He wouldn't eat now he eats faster than the other horses. It's amazing

I love this product! GutX has literally works! I had a mare with huge behavioral issues, she was scoped and had Ulcers. After a second scoping, she had to be medicated an additional 2 months and was free of ulcers. I put her on GutX. A year later after a lot of stressful situations, the mare started having behavioral issues again, we scoped her and she was clean of ulcers. The mare ended up having ECVM and had to be put down. The discomfort this mare was in, should have given her ulcers, but did not on GutX. Thank you!

Very good product

Haven't had a colic since I started my horse on GutX a couple years ago. He was always having tummy trouble prior.
Gilbertson M.
Helps my older horses.

All 6 horses are looking great.
Kristin T.
we have used this product for several years on many of our horses and we are happy with it. Horses are healthy and look great for their age.

Paint is 30 YEARS old and because of 100x Equine, he is still teaching grandkids. He has suffered from fecal water syndrome. GutX is literally a lifesaving product for Paint. Before GutX he was consistently losing weight no matter how much he was eating. And, he was eating…but he was gaining no nutrients. Within one month, he began gaining and gaining! It has been a true miracle that he has recovered and continues to LOVE time in the arena. It’s where he truly shines and it’s apparent that he still wants to be there. I give 100X Equine all the credit!

I have 2 horses that have allergies it has help them tremendously with that and there ulcers. The one rides way better in the horse trailer. There products don’t have any ingredients there allergic to and there not allergic to the GutX. Love there products!
Deborah B.
It's part of our daily feeding routine!!
Christine Z.
Gut X gave me back the horse I fell in love with.! Its much more affordable than paying for ulcer care. He's calmer, both for cinching and under saddle. He's more affectionate. He doesn't mind the taste.
Karen R.
My horse is much calmer to trail ride with
Jordyn S.
My girl has been on GutX for about a year now & it has really helped with behavioral trouble caused by ulcers. We love GutX!
Candy M.
I started out using GutX on my Morgan about a year and a half ago. Once I saw the great results, we started using it on our other two Morgans. It’s a great product!
Skylar K.
Changed my horse in more way then one!!!
Candace H.
Works for my old horse.
Jeannette L.
I used these products with my elderly mare. She was nervous and had come through some physical and emotional trauma when I adopted her. She did really well with the Gut, Joint, and Hoof formulas! I will use it with my new horse, especially the Calm X blend!

Love the product!!!!

Starlight, a rescue horse that was found May 24, 2026, out on a mountain road. He was picked up by Equine Spirit Sanctuary, put on a rehab program that addressed his emaciated and dehydrated condition, with frequent meals which included a mash. We added lots of Gut-X to the mash the first couple weeks, to help him transition from starving to thriving. The second photo was taken July 8. He still has a long ways to go, but is doing great!
Abby
I started my older gelding on Gut X just recently because I had heard great things about the product. His coat has more shine, he has more energy, and he isn't cinchy when putting a saddle on! I will definitely be keeping this on his diet plan and will recommend it to others!!
Jil E.
This is Wally, my 23 year old grand prix jumper with his lease rider aboard. He was her grandmaster for learning to jump. GutX kept him calm and relaxed for her daily riding and at the shows. Amazing stuff! I've used it on my own riding horses after seeing it work so well for this team.
Jeanie S.
We had this rescued gelding on Gut-X shortly after he was donated to us about 3 years ago. After a couple of years, we thought he might have healed, so we took him off Gut-X, and kept supplementing with probiotics, and feeding wet mash from hay pellets. After a few months, he started to become less interested in his food, and was getting irritable again. We put him back on Gut-X at the end of June, and he is already improving!
Karen F.
I have used Gut-X for 4 years with my ulcer prone TB broodmare who has maintained her weight and attitude very well. I just started a new 11 yr old TB on it for traveling. I trust this product implicitly. Thank you
Katie T.
We were really struggling with the overall look of our TB- once we introduced GutX, everything else that we had already been doing just clicked into place. These photos are just 4 months apart. Super amazing changes.
Jen B.
Great product. My horses are happier and look amazing on it. Easy to feed and a great value.
Dorothy
I have tried so many products to help this horse. This is the only product to make a difference.
Jeffrey A.
100 x and Guttx have been game changers with my show horses
Patricia W.
I’m using GUT X on 2 retired race mares - one is 11 the other is 21! They look awesome! The 21 year old looks and acts like the 11 year old. ! The 11 year old TB never had much of a tail, it barely rubbed the top of her hock now it’s about 5-6 inches below the hock!
This is a great product! Thank you!
Christine M.
My horse, Tahiti, is a Draft mix. She is 26 years old. All of her life she had cow poop - always really loose. I tried everything to no avail. Then I heard about GutX. It took about a month to see a remarkable change in her poop. For well over a year now, she has normal poop.
Brian L.
Love the results I get with my Horses.
Patricia W.
My performance horse is 19 years old. I have been giving him Gut X for at least 18 months. He has a sensitive stomach and traveling tends to cause irritation. I ran out for about 2 weeks and we had a show during that time. I had been wondering if it helped that much and I found out. He wasn't himself and I could tell he just didn't feel well. We could tell when we saddled him.. Since then he is back on Gut X and back to himself at the shows.
Sharon N.
My horse, a 16 year old gelding, showed signs of digestive tract distress. This was confirmed by a vet exam, and his chiropractor also noted it. After starting him on Gut-X, his mood improved and his symptoms improved. Gut - X is part of his regular maintenance program and it helps keep him in performance shape.
Laurie C.
Love the Gut X product
Laurie D.
so far, my mare seems less grouchy so that is huge for me.
Tabitha S.
I started using Gutx 3 years ago. It helped my older guys keep thier weight on and my younger ones stomach coated. They all get it.
D L.
Had my horse couple years he’s over 20 and each time before and during tacking up cinching him even just touching his sides he would try to bite or kick or buck after two months of gut x he has completely stopped at the bad behavior to the point that my least experienced child rode him without issue…completely shocked in the transformation and super pleased..we thought we may have to scope him and get into way more then we planned so finding this product has been amazing
Vicki D.
This is Cashew, he is an AQHA gelding. Cashew is currently on GutX and he feels amazing! Love GutX!!
Beth R.
A staple in my barn. This horse in the picture has been battling laminitis and he cribs and I give additional doses and he stops cribbing. I give it right out of a syringe.
Debbie M.
Love gut x my horse is doing great on it thanks so much
Heather B.
100x equine has made huge improvements on my barrel horse and my old senior! These supplements not only helped with weight gain, but increased mobility and helped develop muscle mass. Both of my horses are extremely hard keepers and 100x equine has worked wonders on both of them!
ASHLEY L.
Love Gut X for my horses!
Karen F.
The horses love GutX. Picky horses even like it.
Brandy C.
Gut X has transformed my colts health & overall attitude. When your horse’s gut is in balance you end up with a happier horse. 100% will keep this in my daily feeding routine. Highly recommend.
Valerie B.
GREAT
Phyllis G.
Dip was suffering from ulcers and Gut X has been a game changer! It has definitely helped with preventing ulcers from recurring.
Deborah B.
Leased TB started on and results within two months
Terri S.
This yearling colt came to us in rough shape, was unhandled, very thin, and covered in rain rot. After just 2 1/2 weeks on our refeed program and GutX he looks like a whole different horse! He gained significant weight and skin has started healing. We put all our new intake rehab cases on Gut X!
Blake
100xequine has provided great customer service. Upon delivery of my order, I received a text message asking if I had any questions as a new customer. I really appreciated this service. I am looking forward to the seeing results of GutX.
Gwen N.
I absolutely love GutX! I’ve been giving it to my horse, Saturn, and it’s been one of the best supplements I’ve added to his program. He eats it without hesitation, and I’ve noticed such a positive difference in his overall comfort, attitude, and demeanor. He just seems happier, more relaxed, and more content day to day.
Knowing I’m supporting his digestive health gives me so much peace of mind, especially since gut health plays such a huge role in a horse’s overall well-being. The quality of the product is excellent, and I appreciate that it’s something I can feel confident feeding every day.
I genuinely believe GutX has been a great investment in Saturn’s health, and I’ll definitely be keeping it as part of his routine. I highly recommend it to anyone looking to support their horse from the inside out!
Kynadee B.
My horses love the Gut x and it has them shiny and happy!
Sharleen E.
Made enormous difference in weight and coat of my 18.3hh retired Grand Prix horse
Pheraby W.
My horses are 27 and 28 years old. Both were starting to show their age. Their coats weren’t shiny and they had both lost weight and muscle mass. With GutX being the only change that I made, they both have gained their weight and muscle mass back and are more active. And now are incredibly shiny.
Anneka
I have used gut x and have had positive results. Product is easy to use and my horse seems much happier.
Catherine G.
100x supplements is a staple in our barn! It keeps our horses happy, healthy, and shiny!

Christine R.
Great stuff
Cheryl S.
I use the GutX, have been for many years. Going to try the Osteo-Max for my 28 yr old Arab who is very lame with arthritis. I have been trying Equiox, bute, turmeric and nothing has helped
Lauralee C.
I use both Osteo Max and GutX
for my 24 year old show mini, who is currently retired and GutX for my other show minis. So far so good
Lora Lee A.
It really helps the 3 horses we have it on
Beth B.
GutX is an important part of my horse, Robin's, recovery from ulcers. Robin went from not eating and drinking after traveling, rubbing his ribs on stall walls and misbehaving on the trails to a quiet, calm good eater and drink when traveling after I realized he had ulcers and needed treatment. GutX every day at home plus Omeprazole and Outlast treats before and during traveling has made him a different horse.
Check out my video about ulcers in trail horses on my Iowatrailrider channel on YouTube.
Brooke R.
Abby my 13 yr old mare lost weight after she foaled. She seemed not like herself and overall sluggish. I started osteomax and she has found her shine! She runs around at ease and has managed to gain weight effortlessly. The before and after pictures speak for themselves! Thank you!
Cindy T.
Works good! I’m using on my mare that has a problem with sugar. Hope it helps with her soundness.
Vicki D.
I LOVE THIS STUFF I GIVE IT TO MY HORSE AND ALSO TO MY MINI PIG THEY BOTH ARE DOING WELL ON IT HELPS A LOT
Charlene C.
Keeps my mare going great
Catherine B.
Keeping my yearling happy. No upset tummy’s for him.
Barbara S.
I rescued my mare, Dolly, 7 years ago. She had a heavy load of red worms and tapeworms. I have managed to get rid of the red worms and so far this year, no tapeworms. She also has Fecal Water Syndrome. I had to learn and research trying to find remedies. My girlfriend suggested GutX. I was skeptical. I had already tried so many things combined and separate. I started her on GutX over a months ago. Her coat has deepened and she has dapples. And! She has a clean bottom. I WILL continue GutX.
Cassidee D.
GutX has helped my gelding in more ways than I can count! I love this product and would recommend it to anyone!
Chris M.
100x products have helped each horse we've used them on! Our horses are older but everyone says how youthful and athletic they still look. Going to give the calming product a try on a younger mare.
Tammy B.
Even over the winter, my two four-legged kiddos did so well on Gutx! They are maintaining weight and feeling great!
Samie L.
Your products have and continue to keep both of my horses healthy and happy. Thank you
Liz T.
Ten days, ten days and my HARD keeper senior gelding has made DRASTIC Progress! From having no energy and considering euthanasia to running through the pasture like he was 2 in ten days amazed me. I have no words besides THANK YOU 100x Equine. Thank you for giving me my partner back!
Susan M.
I absolutely love GutX! My mare had been showing signs of discomfort, and at times her attitude reflected what I believed was gut-related pain. Since starting GutX, I've noticed a remarkable improvement in her comfort and overall demeanor. She seems much happier, more relaxed, and back to being herself. I'm so grateful for the difference it has made for her, and I highly recommend GutX to anyone looking to support their horse's digestive health.

This is a staple in my barn

Wonderful products that keep my horses feeling their best!
KYRIE R.
The palomino in the photo had massive ulcers and had them twice a year where I thought he was colicing but it was actually ulcers so vet put him on ulcerguard which did nothing and a dear friend Ann Alley recommended 100x gutx and he has been a different horse since put on weight and very much a happy boy getting into everything again. Thank you gutx and 100x Equine for this amazing product
Ruth E S.
Older horse. Seems more comfortable
Macy R.
My 8 y/o OTTB has been on GutX for 6 months. She has gained weight and has gastric ulcer symptoms have disappeared
Joey L.
My horses love it! They feel so great. They will basically eat it raw! It’s one of my favorite supplements to use! I use the OsteoMax , GutX and the RegenX,
Christy B.
We’ve just started our journey with GutX and I feel really good about helping him out. We’ve been showing almost every weekend since March.
Erin S.
My horse was stalled for nearly two months due to a hoof injury, and his stool became watery due to the stress and change in his routine. I gave GutX a try to see if that would help, and definitely have seen a major improvement! He is turned out again now but I am keeping him on it since it seems to be helping him overall.
Barnett K.
I can’t say enough good things about Gut X! My horse, Pokey, absolutely loves it and eagerly eats it every day. Since adding it to his routine, I’ve noticed a positive difference not only in his gut health but also in his overall mood and attitude. He seems more comfortable, happier, and settled, which has made a noticeable impact on his performance and daily well-being.
It’s reassuring to know he’s getting quality digestive support while enjoying every bite. If you’re looking for a gut health supplement that your horse will actually love and that delivers results, I highly recommend giving Gut X a try!
Arva E.
My 24 year old mare was diagnosed with ulcers two years ago. Vet treatment plus a change in lifestyle helped tremendously, but she still wasn’t quite her usual self. I added Gut-x to her diet and within a month she was back to being her sassy adorable self. Recently she started showing symptoms again (girthy, grumpy, biting at my daughter’s feet when she rode) so I immediately more ordered Gut-x. A few weeks in and she’s feeling great.
Phyllis G.
Gut X has been a life saver for my horse Dip!
Kristine W.
I decided to try Gut X because my overall easy going mare started to hate work. We primarily trail ride, and she started being incredibly unhappy during our rides. She became spooky and just overall nervous about everything while we were out. I raised her and have loved everything about her until the recent shift in attitude had me contemplating selling her. I started her on Gut X 2 weeks ago, and while I don’t know if it works that quickly, we just got back from the best trail ride I’ve had with her in a long time! She was relaxed and actually seemed to enjoy being out. Very excited about our future with this product.
Beth H.
My mare has been on Gut X for over a month and I am thrilled with the results!
Abby
After putting my older horse on Gut X he has been so spunky and you can tell he feels a lot better! I will definitely be rebuying this!!

Great product! Love it!

This stuff actually works!! When we bought Hitch a little over a year ago, his coat was long and rough. He stood parked out all the time and the previous owner said he bucked her off and was flighty. I suspected ulcers and started him on Omeprozole. We saw improvement after 45 days, but his coat never fully shedded out and he struggled to put on weight. I had another horse on GutX, so put Hitch on GutX too. I am AMAZED, truly AMAZED by the results. His coat is gorgeous! Not just shedded out with a nice short summer coat, but he is shiny!! He is no longer stressed and on edge. His sweet personality has come out! He is no longer at the bottom of the hierarchy in the pasture. His performance in the rodeo arena has greatly improved - I never thought he would be as fast as he is now. He is just a different horse. I am in awe that a squirt of GutX once a day has made such drastic improvements! No more expensive Omeprozole treatments - GutX is the way to go and I now have three horses on it daily. Thank you 100x!!! Hitch’s life did a 180 and we all benefit from that!
Janis M.
Bella was very thin and crippled when I paid to rescue her. She was a hungry girl and not social with the herd at all. I suspected ulcers so started her on Gut X. After 2 months she' gained weight and is much happier and getting along well with the rest of the herd. I plan to keep her on Gut X for quite awhile.
Ellen B.
Gut X has made all the difference in my horse. He isn't bloated and fat anymore. He is very nice looking.
