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!

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.

Gut X has made all the difference in my horse. He isn't bloated and fat anymore. He is very nice looking.

Recommended by our team after our horse had surgery for strangulating lipomas .

My 22 year old Halflinger has had FWS since I got him 3 years ago. I tried all kinds of treatments with no success. 2 pumps of GutX twice a day and a scoop of probiotics has worked - no more dirty tail!

My mare gets nervous with all that goes into
Horseshows with tailoring, new stall, different food, new neighbors, etc and I wouldn’t show her without gut-x! Thank you for the best thing I’ve ever used for her gut
Clint S.
Within a couple of days using GutX my gelding was feeling so much better!! I'm keeping him on it for sure! Love all your products they really work!

Good product!

Max is happier and less cinchy with GutX
Kisha H.
We bought Charlie recently and due to the stress and changes to new feed, she became "a little loose". We of course put her on GutX right away and within a few days, her stool was solid and her coat began to shine! I keep all of your products on hand for all fours my horses!
TAMMY R.
I’ve been using GutX for years and love it . My 2 youngest have been on it since weaning. It helped them through the weaning process and kept them healthy and thriving through there training . I love it so much , my whole herd is on it now .

Very nice product! GREAT customer servoce!!!

My horse had lost quite a bit of weight almost overnight after having to move to a new barn, and just overall looked skinny and unfit even though he was eating a ton. We added GutX and within a month, he put the weight back on, looked healthier and had a gorgeous shine back to his coat.
Kimber K.
These rescued and now retired therapy horses have never felt better! We ran out for a couple of weeks and they could feel the difference! Their coats are shining and the pep in their steps is back again!!! Thank you so much for such great products!
P.s, MaxCalm is a game changer for trailering!
Jessica M.
After every Queen Run and barrel race, our 24-year-old horse, Mac, is treated nightly with Gut X and Regin. Since adding these two products to his routine, we’ve noticed a huge difference!
Long trips and busy weekends used to be much harder on him, but his gut health has improved significantly, and he stays comfortable even after traveling. He never misses a chance to come running to his bucket at feeding time!
Performance-wise, we’ve also seen a noticeable difference in all three of our horses that are on this regimen. We’re very pleased with the results and look forward to keeping them on these products.
Thank you, 100X Equine, for helping keep our horses feeling and performing their best!
Cassie K.
Works great!

I just Wish it didn't cost so much money.

Used GutX for a period of time. Then being an overthinker I wondered if I really needed to. Stopped for a while. I am now feeding it again and very happy.
Shirley B.
My horse loves it! It makes him feel good! And when he feels good, I feel good!

Osteo-MAX
I cannot say enough and absolutely love the Osteo-MAX !! It has made such a difference and almost stopped any prescription that prescribed medicine from my mayor. She’s older and has had issues for several years and this has been an absolute game changer. I tell everyone about it. I absolutely love the product. Thank you so much.!!!!
Julia O.
I’ve been using Gut X on my barrel horse for two weeks and I’ve noticed a big difference. She seems more comfortable, is eating better, and stays calmer at races and jackpots. Before starting her on Gut X, I was always worried about ulcers because of the stress that comes with hauling and competing, but since adding it to her feed, she has stayed healthy and hasn’t shown any signs of ulcer issues.
What I like most is that it’s easy to feed and gives me peace of mind ,knowing I’m helping protect her stomach before problems start. My horse is performing well, keeping her weight on, and feels great. I’ll definitely keep Gut X in his program and would recommend it to anyone looking to help prevent ulcers and keep their horse feeling their best.
Janice C.
This has helped my 21 year old lesson pony. I'm pleased with the results. I haven't gone to the 1 squirt a day yet. I'm hoping it's just as effective.
Kelly S.
Amazing products.
It's helped one of my mares kidney values come back to normal!!
She's on the amino gutx and hydro max.
Hope for many more years.
Madison K.
I’ve been using GutX for about 2 years now and I absolutely love this product. The GutX helps my horses perform at their best and keeps them feeling good traveling down the rodeo road. I’ve had a horse come up with bad ulcers and wouldn’t even enter the arena and after using GutX he started walking into the arena calmly. GutX is now a staple in my feeding program and I start all my new horses in it.
Kandace D.
My horse, Tango, is 24 years old this year. He is a Palomino. His white tail has never been white (if you know what I mean) except for the last 2 years when I started him on Gut X. He has had a complete transformation with his stools...and his tail really is WHITE. My only regret is that I didn't start him on this YEARS sooner! Thank you
Denise B.
I just started the GutX with my new mare and I've already noticed a difference! She's been gaining weight really well and handling all new experiences really well too. I'm very excited to keep her on GutX to help set her up for success.
Hope W.
Finn's tummy feels much better with the Gut X
Nancy T.
My horses love your products. Great stuff I have ever used. I just ordered another two gallon of Gut X and Joint.
Thank You

What a change! Since using GutX and Max Calm, my mare has improved greatly in focusing on her job. I can’t wait to get back in the show ring! GutX and Max Calm will be a staple in my barn. They work while not breaking the bank!
Conor B.
Keeps my horses feeling great and performing at their highest

Horses do great on this prouct

I have a 17yr old draft paint cross who has fecal water syndrome. She’s been on GutX for almost 5yrs, I never plan on taking her off it! It works like a charm, and quite honestly they only thing that works for FWS!
Sandie H.
Have been using your products for years they do a great job for my horses. Thank you for good products.

This colt has always had a bad attitude. This has been great for changing that to a happy disposition.

Guts has kept my colicky horse colic free for years! Great product!
Cathy S.
My Vet and any visitors say my 29 yr old mare looks great and does not look that old. She has DSLD and it has been progressively effecting her recently. I cannot say enough about the Gut-X and Osteo-Max. She has no back teeth and the Gut-X has kept her gut on track along with keeping her colic free. Her joints are affected by her DSLD but her top line and body condition have been great.
I would also like to thank Madison for asking about and helping with her. She is a pleasure to talk with and continues to keep in contact about my mare. I value her opinion what she sees in the photos I have sent her.
I struggle as a worried horse Mom when it comes to the health and well being of my animals to give them all I can to the end. I delivered this mare and she has been an awesome show horse . She went on to be a lesson horse and bring 4-H kids to State and local shows.
She deserves the best I can give.
Chesney L.
love this product! completely changed my horses gut issues!
T W.
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.
Heidi W.
I’ve been using this for almost two years my horse is 24 I’ll do anything to keep her gut healthy
Alfred B.
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
Michaela B.
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.

Great
Amanda P.

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
moriah v.
Love the products

I love gut x
Karen S.
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!

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!
