My 26 year old stud was dropping weight and I tried everything from different feed, supplements, vet visits very often……after about a month on GutX you could really start telling a difference. Love this product and it will be part of my plan from now on.

I’ve been using this for almost two years my horse is 24 I’ll do anything to keep her gut healthy

Happy with product and now subscribed !

My horses do do much better using Gut-X. I just started giving to my granddaughter's horse. He's wasn't eating well and I can already notice a difference. Thank you!
Kim H.
Luv this product!! No colic symptoms in over 2.5 years
Sandy C.
Product works really well for my little mare.
Kay L.
It works great
Alex J.
I’ve recommended GutX to every client that I’ve had since seeing its impact on my personal horses. It helps with joint mobility, gastrointestinal health, and overall comfort. Happy healthy horses!
Pamela D.
My mare has been on gut x for years. I never run out, she’s a new girl since being on it
Alfred B.
My horse seems to love.. very palatable. I started off with two pumps in the morning and have since cut back to a single pump.. no issues to report. I can’t complain either.. keeps my boy regular and colic free. I’ve also been getting a lot of compliments on how he’s filling out… I see him every day so it’s hard for me to see the changes… however, I do see the changes in his coat and dapples!!! Very nice

From "Oh..." to "Whoa!"
I bought this yearling stud colt for his incredible pedigree, but when I first went to see him, it was clear he needed some TLC—matted, underweight, and under-muscled after being run off his feed by a dominant mare.
Because standard grains gave him total "grain brain," I put him on a ration balancer topped with Max Calm, GutX, and Amino Max. The results speak for themselves! The transformation between his arrival on March 25, 2026 and his latest photo on June 7, 2026, is night and day. He is finally turning into the growing athlete he was bred to be.
Putting weight on a young horse safely is a marathon, not a sprint. Along with quality hay and proper deworming, 100X Equine has been the essential boost he needed to build muscle, while simultaneously protecting his gut and keeping him level-headed. I wholeheartedly believe in these products—the proof is in the pictures! Thrilled with the results in such a short window.
Jeanne L.
My horse is so much calmer and has a better frame of mind, making him much more enjoyable to work with and ride. Once he got in the gut x, his whole demeanor changed for the better!
Heather D.
We haven't had any issues with ulcers since starting GutX, and Lady has been on it for a solid year now. I believe it plays a huge part in helping her look and feel her best!
Sherry G.
Great product
Andy B.
It’s amazing how much difference GutX makes.
Lisa H.
The GutX product gives this elderly 1/2 Arabian the ability to still take care of the newest riders. I can’t say enough good about it.
david m.
Great
Amanda P.
Since putting BlackJack on this product he has been jumping so much better!! We love it!
Will A.
Spicy mare has definitely calmed.
Christina s.
My mare was so fussy and suffered from ulcers the gut x and the chastberry worked so well and my mare is now competing and not fussy!
Pamela M.
Since I have been using the gut X my mare has relaxed and seems to focus better on her barrels
I think it’s because she feels good inside and out and doesn’t get do anxious anymore

Love the products

6 months ago my 19 year old thoroughbred was loosing weight.
His ribs were showing & he didn’t look great.
I had bloodwork done to see if we could identify a cause for his weight loss. Everything came back negative. This was obviously a great result but didn’t answer why he was getting so thin.
I decided to put him on Gut X.
Within a couple of months he started looking better.
This photo was taken at the beginning of June. He looks healthy & is definitely feeling happier.
Stacy C.
This has been game changing for our show horses. It helps with traveling stress and keeps our horses happy and feeling great year round.
Bobby R.
Our beautiful gelding is 26 years old and his weight and coat look fantastic I attribute it to the Gut-X.
Mike
I've had a great experience using Gut X from 100X Equine. After adding it to my horse's daily routine, I noticed positive changes within a few weeks. My horse seems more comfortable overall, maintains a healthy appetite, and has been looking and feeling his best.
One thing I really appreciate about Gut X is how easy it is to feed. My horse took to it right away, and I didn't have to fight with picky eating or feed refusal. Since starting the supplement, I've noticed improved condition, a shinier coat, and a more relaxed attitude, especially during training and travel.
As horse owners, we know how important digestive health is to overall performance and well-being. Gut X has become a regular part of my horse's nutrition program, and I'm very pleased with the results. I would definitely recommend it to anyone looking to support their horse's gut health and overall wellness.
Britni K.
Our beautifully spicy red mare LOVES her GutX!
Cortney A.
I use gut-x for my two Standardbreds and it is amazing! I couldn’t imagine them without it. Recently I added the calm as well for them an extremely happy with that product as well. Highly recommend 100-x products
Kari P.
Absolutely LOVE all your products!!!
Amanda B.
My gelding has been on GutX for 2 months and I am so happy with the results. He is more focused and less anxious. He used to weave in the trailer and in his stall, that has all stopped. Gutx is one supplement he will always have.
Kelly C.
Absolutely love the Gutx and have turned several of my friends onto using it! It made a noticeable difference in my show gelding when using it he stopped be girthy and being irritable when groomed snd became overall happier and calmer
Holly C.
I just bought my 2nd one.
Carol M.
My Gypsy mare has always had a spicy attitude, and is opinionated about her belly being touched. Sometimes she is cranky. I started giving her GutX about a year ago, and she seems much happier now.
Teresa N.
I have 2 horses om GutX for 2 different reasons.
Willie is an EMS, 23 year old warmblood gelding that has been on Prasend for about 4 years. Willie developed Fecal Water syndrome and I added GutX to his grain once a day and the FWS was controlled.
Watson is a 12 year old warmblood gelding with a "nervous" stomach. My trainer noticed Watson's gleaming coat and I mentioned Gut X. My trainer now uses GutX for many of her training horses. Wish my recommendation to trainer had helped with my GutX order and price. My horse will be returning home after being @ trainer for a year. My barn burned down and She has kept Watson for me. I will need to order some GutX. Terri Neese
Mikela R.
Has worked wonders on my cinchy mare!
Dianna S.
I've used Gut X for a couple years now. It helps my horse with fecal water syndrome.
Marla C.
My boys at 27 and 15 go like young boys. My chestnut suffers from ulcers and EPM and GutX keeps him comfortable and happy and my dun wonder horse is 27 and still trail rides carrying 250 lbs all over the Ozarks. Thank you for such wonderful products!
Jackie K.
I have two horses a 11 year old QH and a 5 year old Gypsy/percheron. My gypsy got grade 2 ulcers from being in heavy training then moving barns. We treated with vet prescription meds then immediately added GutX and 30 days later nothing! All gone. She’s since in a new training program and moved barns and no issues. This stuff is amazing so I put my second horse on it and now they both take it to prevent GI issues. I won’t go without it for them. Highly recommend
LISA R.
Definitely can tell a difference in our senior dogs.This stuff is great!
Monja B.
I’ve started using this after my horse’s first ever colic episode. My horse eats it right up with his grain. He’s been on it for a couple months now and he is looking better, especially for just turning 20 years old. Easy to feed and seems to do what it says!
whitney h.
My horses ulcer symptoms have significantly decreased!!
Beth H.
My mare has been on Gut X for over a month and I am thrilled with the results!
Kendra R.
Wolfie, a retired OTTB, has suffered on and off with ulcers. After a short time with Gut-X, he is so much more comfortable and back to his old self again! We are so happy we have found an amazing product to help this senior guy enjoy his retirement days!!
sheri d.
Gutx has helped our 3 and 4 yr olds stay calm with no loose poop and no stomach issues in general
Sherie S.
My beautiful boy Max was showing signs of ulcers and just a really bad attitude. I started him on the gut X and there was a definite improvement. When I ran out I didn’t reorder and they started coming back. So I put him back on it and he improved again so now all my horses are on it for life!
Terri B.
I have use gut x on my daughter mare that was showing signs of discomfort when getting saddled up. Once being on this product she has no more signs of discomfort. I also have our older mare on joint flex. I feel like she is getting around a lot easier since we put her on this one. I love all 100x equine products. Everyone that I have tried I has been completely happy with and have bought many times and will continue to buy.
Olivia W.
My horse has felt better and I haven’t had the first problems with ulcers since I started using this product..I recommend this product 100%
Theresa F.
Started my older boys on gutx. It has done well with gut health. But what I’m really impressed with is receiving a text message, checking in how everything was going from the 100x team! The Gal I was messaging was absolutely incredible and helpful. I shared some concerns I had and she was able to make some different recommendations. With that being said, I’m excited to try some of the other products To see if I can get some specific results I’m looking for! 5star Customer service!

Judy O.
Gut X works great on my horse with a sensitive belly
Debra C.
I use gut x for pregnant and nursing mares, weanlings, yearlings, horses that are showing - pretty much in every life stage and activity level
Mark B.

Megan E.
My horse has greatly benefited from GutX. Her stomach has never been happier!
Natalie G.
I noticed a difference almost right away after starting my 9 year old mare on Gut X, and 30 days later she was a totally different horse. Calm and easygoing, no more issues with sensitivity during grooming, and no more fecal water. She’s been dealing with healing from a bout of ulcers for the last year, and the addition of Gut X really helped get her back to normal. I love this product!
Skylar W.
i love gut x
Tammy F.
Keeping my 3yo fat shiny and happy while in training!
Shannon S.
Have been using Gutx for 2 1/2 yrs, seems to help my mare.
Jill S.
I have two older mares that this product has help with their day to day mobility. Both used to walk up from the pasture with visible limps. Now, they both walk across the pasture not limping and will come trotting up from the pasture.
I have used the Gut-X on a young stallion that is hyper-sensitive to fly bites and would scratch himself raw on his shoulders and neck even with being on antihistamines. His has been on Gut-X for a year now. So far this year with no antihistamines, he has not scratched himself raw. Fingers crossed he makes it through the summer.
Lindsey S.
I started my mare on gut x after my friend urged me to try it because I questioned that she possibly had ulcers that had gone untreated. After being on it for a couple weeks I could already see the difference in her attitude, and even the way she rode. Very satisfied with the product, and I plan to start my gelding on it here shortly for maintenance!
Kari P.
I have been using this fabulous product for years and it has made a huge difference in my horse's condition.
Jodi E.
Gut X helps my horse with his loose manure. At least they resemble horse apples now, LOL!
Ariel U.
My ulcer prone horse should really well on this!
Keri L.
My mare is 24 years old and hard to keep weight on her. I have tried many thngs, but so far the Joint flex has worked best. She likes the taste and it keeps her moving and running barrels. I am now adding the Amino Max to see how that works.
Danny S.
This is the 2nd bottle I have purchased. It really works. Can tell such a difference in him.
Wendy J.
Gut-X helps keep my show horse healthy, happy and focused. His copper coat shines like a brand new penny! He’s energetic,, kind and loves to work. He gets to be himself when his digestion is so well balanced!
Trina C.
My 20 year old energizer bunny Mustang was hard to keep weight on and suffered from ulcers so I decided to give 100x products a try. After initially treating his ulcers, my vet suggested I put him on a daily magnesium supplement and my horse nutritionist suggested I add ashwagandha. When I discovered the Max Calm had both plus more it was a win! I bought both GutX and MaxCalm to add to his evening mash bucket and he is a changed horse! His appetite has increased and I am getting more focused and controlled energy from him on the trail. We regularly do 10+ conditioning miles and ride Competitive Mounted Orienteering races. I'm pretty confident the 100x products will help us meet my summer goal to enter an endurance race.
Wendy H.
I have been using this product for 5 plus years. It's been wonderful in keeping my 26 year old Friesian's intestinal health in prime condition. I attribute GutX to his longer than normal (for a Friesian) life span. I also use it on my pony who is a chronic colicker. It has helped to dramatically reduce her colic episodes.
Kacy V.
love this stuff. definetly see the difference with our horses.
Linda L.
Before GutX she would kick with back leg every time girthing her up , after using GutX , this behavior stopped!!! I’m sold
Kristin B.
I have a 30+ horse with severe fecal water issues. I haven't even finished the first bottle and it has almost stopped. I was having to wash his legs every other day and adding skin protection. I have not had to wash his legs in 4 weeks!!! I was skeptical but I'm sold on this Gut X
Madeline A.
Gut -X has helped my 22 year old mare in so many ways. From temperament to topline there has been such a drastic improvement. Having got her at 20 I walked in not knowing what she had been through, but knew she needed a little leg up. Gut-X gave her just that and more! I will be an avid supporter of it for all my horses forever.
Corey J.
GutX has really helped my draft mule deal with the gastrointestinal impact of multiple pain meds and older age. He really perked up after about 3 weeks on GutX and the difference was remarkable! Madison routinely helps me sort out what each of my horses needs and is quick to respond and offer great advice.
Kisha H.
This is my new baby horse, just shy of a month on GutX. Her stool was pretty loose due to the stress of trailering, change in feed, and a new life. She is happy and thriving now!
Avery S.
I always use it on the road the GutX and it keeps my horses guts calm and I just really love it.
Catherine P.
I was given my horse as her prior owner was ill, from day 1 she was nervous and cinch when saddled . As my barn mates all use your products, I decided to try the Gut x and it has changed my horses world no longer cinch and nervousness is much better! Thank you so much for a great product
Heather D.
As you can see ! Amazing results!
Laura N.
We were ready to give up because no matter what products we tried we could not control our geldings anxiety and ulcers when we away from home. A friend told us about GutX and since we started on GutX as part of our feed program we have a different horse. The easy to feed formula has improved digestion and calmed his anxiety and behavior. I would recommend GutX to any horse owner who is interested in improving their horses overall gut health.
Autum M.
Horse finds it palatable. We use this for our mare on the road to rodeos. It helps ease her tummy, and it's easy to travel with.
Carol D.
Used it for many years.
Diane N.
I've been using GutX for about four years now. I'm totally sold on it! My older horse (21 this year) is prone to ulcers, but he hasn't had any problems since I started him on GutX. It even helped him adjust to the medicine he now has to take for Equine Cushing's disease. So naturally I am giving it to my new young horse as well - I want to keep her happy and healthy. Good work, 100X Equine!
Lisa H.
Both of my horses. 21 & 9, have done well on GutX! My 9 yo mare was was beside herself on alfalfa and at first thought it was just her temperament. My 21 yo gelding g would take his jay and dump it in his water and was losing weight. Tried GUTX and it’s been a lifesaver for both.
Teresa H.
Have been giving Gut X to my 27 year old quarter pony for about 3 weeks for potential ulcers (extra cranky and didnt want to be touched anywhere on her barrel) and already seeing the difference. She didn't want to touch it the first few times even when it was mixed with grain but competition from her pasture-mate to eat it changed her mind. Now she eats it freely. Even the farrier noticed she isn't sensitive around the back half of her barrel any more.
Randi R.
Gut X is a game changer!! My horse looks and feel amazing!!
Amanda B.
Great product.
Holly S.
Both my mares are rescues and came from bad situations! Tried other products such as Magna Guard and nothing worked. This is two months after being on Gut-X! No more cranky mares, biting at bellies , or anxiety! Overall happy horses and beyond thrilled with the results! Will
continue to use from here on out
Christine J.
I use GutX on our Mare who is a bit of worry wort It has worked wonders on her. I highly recommend. I’ve had no issues with her health ever since I’ve started using it..
Judy
I have used this on my older horses.
Lee H.
This has really helped our pony and performance horses with their over all busy condition
Valerie D.
My gelding is 34 years old and he was having problems with the squirts so I tried the Gut X
and it has been such a great product. No more problems and he’s very happy now and so am I.
Thank you so much for having Gut X for my one in a million boy.
Kim R.
Hands down the best supplement. All my girls look and feel their best.
Donna J.
Boone is a 1 yr old Warm Springs Reservation gelding. He came in with a thick winter coat that still hadn't shed out when all the others were shed. I began using GutX and within 30 days he has shed out and has such a shiny coat that feels like silk. I'm amazed at the difference. I have said it before, liquid gold!!!
Suzie K.
I have used GutX for over 5 years and it has worked wonders on my horses. Keeps them gut-healthy even in stressful times.

Candy F.
I give Gut-X to my senior horses (and one not so senior!). I call it colic insurance, and we've had success with them all on it.
Jana M.
I’ve been using this product for years! GutX is by far the best digestive product on the market. All of my senior horses just glow with health.
