Have a 9 yr old with gut issues on it quite some time seems to be better than he was. Started my 26 yr old on the osteo max and she is moving better than she was on certain days .
Jaymie B.
I have had my 22yr old PSSM mare on both Gutx and Osteomax for a while now. It has made her be rideable again and has definitely extended her life and quality of life. She has been able to regain weight and has became a lot more active and asking to work again. Before starting these products I didn't know if I would ever be able to get on her again and was close to letting her go. Now she is happy and demanding to get out of her stall and work again. I have had this horse since she was 4 and I was young and we grew up together and she means the world to me. Thank you!!

We couldn’t get Beat to gain weight at all but once we put him on Gut X and Osteomax he started gaining and filling out

As you can see Maisie loves her gut X , usually she neighs when she sees the syringe. I also give it to my old rescue along with osteo max . I love these products and have recommended it to several friends with horses .
These products are game changers, they do work
Thank you for helping me help my horses
Brenda K.
Thank you 100x equine for making such great products!! The Osteo max and Gut X have been a game changer and helped our horses to be there best !!
Constance H.
My mare, Bo, didn’t have the best gut movement. After a couple bouts of compacted bowels, I have had her on Gut-X for several years now and have not had anymore issues. I have also added Osteo-Max to her feed program now as a preventative measure to injury for the competitive sports we participate in.

Osteo-Max and Gut X have made a huge difference for my horse, Cape.
We travel often between Virginia and Florida, and since we started using this duo, everything has changed. No more stomach issues on the road. His injections even seem to last longer.
These products have taken so much stress out of our lives. We’re truly grateful.
Vickie S Y.
I have been giving Oste- Max to two of my barrel horses for two years now, no injections have been needed. I give Gut x to four adult horses and one yearling that tends to have gas issues, since the gut x doses every day the gas problem hasn't returned. I love these products I don't have any plans of stop giving them. I also have noticed my Itchy mare no longer itches since being on Gut X that is a win , win for us.
Debbie R.
My navicular 28 year old boy is doing great, love all the products

Great product
Elizabeth L.
Gut X made such a difference! Not only is she happier and seems to feel so much better, but it has really given her a gorgeous notably nicer coat! The osteo X has made her feel and move so much better it has made its use as invaluable as the gut x and now I have to buy both! These products have made more of a difference than any other product Ive tried!
Susan G.
My colt was crabby from the get go and Gut X has made him happy. No more bad attitudes.
Anna O.
This old man just keeps changing and gaining more weight and is feeling his self. We love the 100% difference and he is on guy x, also the osteo-max. I can’t wait to watch him keep growing and changing. This is old many we would have never thought would ever be building muscle up in his wither area but he is.
Alexandra S.
Love the product and has helped my horse.
Deb B.
I brought home an underweight mare and started her on GutX immediately. I also started my IR mini on it, as well as they are both on Osteomax. Seems to really help!
Teri M.
My 25 year old looks amazing!! Use all 3 of the products
Karen B.
Very happy with both products. Gut X and Osteo Form

My 25 year old mare has Cushing’s disease. She has done remarkably well well since putting her on Osteo Max. She got off her feed so I put her on GUTX. No more tummy aches. I love these products!
Debbie P.
I know this product works and don't want to be without it.

My mule (approximately 18 yo when I got her) had been sold 3 times and brought back each time. I was told she wasn't a lovey dovey Mule that needed a lot of attention and was a hard catcher, not a lie lol I think I figured out the problem of her being returned though, Every time I cantered her, she would put her head down and shake it with a few crow hops added into the mix. I'm no expert on animals but after I thought of different reasons as to why, I thought maybe she has ulcers and I don't even know where that thought came from. So I decided to start her on Gut X and that issue with cantering is, and I'm happy to say it, gone! I'm on an extremely low budget, retired 74 years old and it is hard for me, but I recently added Osteo-Max to our feed regimen, as she ,(Squeakers the mule) is about 25 years old now. I noticed yesterday thar her forelock is shiny and softer than usual. Recommended both of these products to other riders and they have corrected their horses issues with the Gut-X. Squeakers is a much happier girl these days, thank you!
LaVerne D.
This product has really made a difference in my horse's health and appearance. Thank you!
Michelle R.
I have been using Osteo-Max along with Gut X for two years. As a 5 year old, she’s still growing, the Osteo-Max and Gut X have kept her comfortable and her coat looks amazing.
Ashley W.
Diablo DC is a 17-year-old Lusitano gelding who has competed successfully at the FEI Grand Prix level in dressage, international Masters in working equitation. He’s a multi-national champion and excels across several disciplines. USEF horse of the year, and a two time Breyer guest horse.
We recently started him on Osteo Max and Gut X. Diablo doesn’t receive any other joint supplements, but as he’s 17 and managing Cushing’s , we feed him Meta High Gain feed and we wanted something to support his joints and tendons.
Since adding these supplements, we’ve noticed a remarkable difference — Diablo is moving and performing like he’s half his age! Gut X has also made a tremendous impact on his day-to-day comfort, especially during the busy horse show season.
We’re so impressed with the results that we’ve started our other horses on these products as well. We highly recommend them!
Ashley R.
My 5 year old gelding had loss muscle tone through his top line and also had a sticky stifle. Seance on Osto-Max and Gut-X his weight has increased and his stifle doesn't stick as badly. Hoping after our second bottle it will take care of the stifle issue all together! is looking very promising
lisa a.
I’ve been using gutx on my horses for years but recently my stallion bowed his tendon & I started using osteomax on him too. Everyone loves it (even the kitties) and I def believe it does a world of good!
Donna J.
My aged gelding is 21 and previously suffered blown tendons in both hind hocks. He's been on OsteoMax for over a year. Recently he was given dental care and the vet was amazed that he is 21, saying, "He's in amazing shape for 21." He has also become an amazing babysitter for my orphaned foals. He runs in the field with the babies, plays Tug-O-War with them, and is actually a bit fat.
I attribute his excellent health to this product, as it has given him so much relief and healing. Thank you 100xequine for your amazing products.
The GutX has also saved me 2 emergency vet visits recently. My BLM mare coliced and 2 pumps of GutX brought her rt out of it.
Love these products. The proof is in the horses
Ronald F.
Impressive results
Kay G.
Diagnosed with deep digital flexor tendinitis. Was lame on front. Started using the gut x and the osteo max about 2-3 months ago. No lameness and about to begin riding him again. Really believe in these products
Allyson H.
We have tried numerous different supplements and osteomax and gutx are the only ones that truly work! I can’t remember which visibly see a difference in my horses movement and attitude after just one week!
Marlane T.
I have been using GutX for both of my performance horses for a little over a year, I have recently added the Osteo Max as well
This is a daily preventative maintenance for both horses
Product easy to dispense and horses eat it
Without any fuss
TAMMY B.
My granddaughter has a 25 yr old mare we are using for trail riding and shows. She came to us thin and crabby. We started her on Gutx & Osteomax. She has filled out and isn't showing her ribs, her hair coat is shiny now, has more energy and a happy attitude! Thank you sooo much for giving Spirit more years of a great quality of life! I've had several people notice her improvement and they have put their horses on Osteomax to help them.
Debby D.
Both Osteomax and Gutx and helping my 21 year old mare through lots of trail rides. This one was over 9 miles with lots of hills! She did great!
Chris N.
My two Percheron geldings have been on Osteo Max and Gut-X and not only do they move better their hair and coats look great. At 14 years old their joints would creak a little and after being on this product their joints are quiet and squeak free. Will be feeding this forever it’s a great supplement.
Christina K.
My mare has been on both osteo max and gut x for about a year. She continuously was cinchy and would come out of her stall stiff. I would do yearly injections. Since being on both of these no injections, comes out fluid and I can tell her gut health is improved as she is no longer cinchy!! Great product!
Lindsey P.
Ellie struggles with navicular and weight issues, since Gut X and Osteomax she holds her weight well, and has been sounder then ever. I run a training/boarding facility and have ever single horse on these products and always will swear by them!
Lindzey D.
So far so good!
Pamela R.
The difference in our horse is amazing, he's at a healthy weight. Muscle tone is the best he's probably ever been and most people think he's younger than 10 and he's almost 21!
Thank you for your products!
Karen M.
Seems to be a good supplement
Miriam B.
I have a 22 yr old mare that was diagnosed as navicular, she has fibrotic myopathy, and an old splint bone fracture. Needless to say, she was lame. I spent thousands of dollars on special shoes,(for 7 yrs!) Magnawave, acupuncture, chiropractic, massage therapy and countless supplements. You name, it I tried it. Then I went to a new vet who suggested I try osteomax for 30 days and then re-xray. The results were incredible! Her navicular bursa is no longer thickened, she no longer short strides becase of her myopathy, and the splint bone has remodeled. She is sound for the first time in 10 yrs! She has been on it for 6 months now and will be forever.
Fast forward to now. My 39 yr old mare was seriously injured in a fall in September of 2025, to the point we were ready to put her down. After very high doses of steroids and many banamine injections, she was no better. She also stopped eating and lost a tremendous amount of weight. She was on daily doses of ulcerguard, but still would not eat. As a last ditch effort i ordered gutx and put her on Osteomax as well. In 3 days she was completely weight bearing and started eating again. I had to syringe it into her in the beginning becase she wouldn't eat. Now she is doing amazing, got her chiro work and acupuncture done yesterday and she is one happy girl. Thank you for your amazing products! I just ordered jointx today, excited to see the results. Sorry for the novel, but this is worth writing about!
Isabel A.
I’m so glad that I decided to use this product, as it has made a huge difference in our horses and pony.
Gratefully yours, Isabel
Ashley F.
My Boys fill so great and my main guy was really lame and dealing with narvicular issues due to farrier problems
We have been on osteo max and gut x for almost 5 months and i wouldn’t change it
It is pricy witch is hard sometimes but I have to have it
Crystal L.
Love these products!!!
Michelle B.
My 25 year old OTTB loves this. He refuses to eat any supplements, except for the Osteomax and the Gut X. He loves both of them! If he misses a day of the Gut X - he gets loose stools. Best product at an affordable price.
R S.
The difference we have we have seen in less than a month on these products (GutX & OsteoMax) is amazing! We have a couple of hard keepers with some ulcer issues and they are thriving and look better than they have in several years! Within the first 6 days coats were improving, weight was coming back on and overall body condition was improving drastically! AMAZING product! AMAZING results! We will never be without it at our barn!
Hearts T.
Our therapy horses are doing so well on their Gut X and OsteoMax!
Jill U.
Enjoy the product
Sherry b.
Working well!
I am happy with both products!
Eddie S.
Older paint prone to leaky gut /stools if not on GutX has helped tremendously keeping his stools normal, and the OsteoX keeps him mobile. Also have my 16+ mare on the Osteo to keep her movement fluid.
cheryl c.
GutX and OsteomaX worked wonders on my two old geldings.
Susan F.
It really makes a difference!
MELODIE K.
Our horses love it and thrive!

I started using gutx and Osteo-Max to help with gut and tying up and have see improvement to help my mare be more comfortable.
A M.
I started Chica on GutX and OsteoMax and she has done remarkable. I am going to order the CalmX to see how she does, we do parades and I normally give her a powder supplement hopefully, this works better. She has filled out, her main, tail and forelock are super long, and she is doing great for 21 years old. Thank you for a wonderful product.

Bailey came to me from a kill pen. He had been down in the trailer and had been trampled by the other horses. He was underweight and sick. He’s been diagnosed with EMS Cushing and the vet said the worst case of Lyme disease he’s ever seen I had put Bailey on Butte because he also had a horrific abscess in his front foot And he was sore all over . He lost more weight after he came here and then with all the medication‘s the doxycycline especially is hard on their gut he quit eating so my friend had a thoroughbred that she got out of the Kilpin and she put him on GX and Osteo Max so I ordered the GX for Bailey And I in two days could see the tremendous difference in his attitude and within the week he was back to eating and now he’s putting weight back on and he’s getting back to being his happy self. I can’t say too much for this product I just wish now I could get him on Osteo Max for his feet. He has ringbone on 1 foot and a star of ringbone on the other , that’ll be the next product I purchase I’m already subscribed for the gut ex and I’m gonna keep him on it no matter what I I wish the Osteo max came in a smaller size so I could afford to get it because I’m a senior citizen on Social Security, and it’s hard to get that amount of money together with all the bills that we’ve had but it’s a great product. Great, great product.
Jennifer C.
Without Osteo Max and Gut X I don’t think Big Mo would still be moving let alone showing at 17! It’s made a huge difference for him and it shows!
kathryn Y.
I use all your products and my horse feels and looks better then ever!! Supplements are amazing and words can’t describe how great your Equilaser has worked on him!! ❤️
Prissy M.
Not only are the 100X products great ! The customer service is highly rated in my book. Thank you 100X Equine !
rhonda m.
I travel extensively with my horses, mainly camping in primitive areas. Rarely are they in pens, usually high lines. They travel on rough terrain and forage is not always the same. I would NEVER travel without Osteomax and GutX.
Donna W.
I just started Osteo-Max on my gelding two weeks ago for lameness in right front. We have two m ore weeks of the loading dose but I already see an improvement. This product is great and I love the ingredients and that it's in liquid form. I will keep ordering. Thank you.
Cortney D.
We loves these products!

I have 2 mares on Osteo max and Gut ex that travel and compete. for both there has been a definite improvement in digestion and joint health.
Ann T.
Sugar our thoroughbreed was loosing weight, started to bite when we placed a saddle on her and became very reactive to the cinch. We started her on GutX and OsteoMax with the initial starting dose of twice a day, then down to once a day for maintenance. Today she looks great, appropriate weight, is back to performing. Great product.
Treana H.
I use Osteomax and Gutx and the results are fantastic. With Gutx my horses look and feel their best. I use Osteomax to keep my performance horses working great. Highly recommend any of the products! We couldn’t be happier and will continue to use the products on our horses and dogs.

Eclipse is a 25 yr old Part Arab with 32 allergies. This Spring I noticed she had a great coat, tail and mane. Her joints no longer click. It has to be that I added OsteoMax and Gut X to her regiment. Will never deny her these products. Thank you!
Lauren C.
We have a 18 year old rescue appendix gelding that has horrible teeth and is a hard keeper. After adding gut x and osteo max he has kept weight easier and built more muscle. He is an amazing horse and I love to see him thriving!
Ellen M.
I was told by a friend of mine about the Osteo max and the gut X for my 11-year-old aged gelding. I truly believed a month ago I would never be able to show him at Congress. But I have had him on the product and showed in the open and finished sixth. I cannot be happier that I found these products.
travis t.
I have great results from osteo max ,max calm and gut ex on my two 16 year old rope horses
Sheila H.
starting my 7 year old mare now, so she has a good start on it now for 3 mos and she seems to be doing great
Jessica L.
I can’t say enough good things about 100X Equine and their OsteoMax supplement. My horse has been struggling with stringhalt, and after my friend ordered OsteoMax for me to try, I noticed a real difference. Within a few weeks, my horse started moving more comfortably and freely, with much less stiffness and jerky motion.
I’ve tried a lot of products over the years, but this one truly stands out — the improvement has been remarkable. I’m so grateful to my friend for recommending it and to 100X Equine for making something that actually works. My horse looks and feels better than he has in a long time!
Lindsey
I have my mare on both the GutX and OsteoMax. I’ve seen such an improvement in her movement and overall health since starting these products!
Susan C.
Works great!
Holly W.
We absolutely believe in Gut X and Osteo Max for our performance horses. They always look and feel great even with the stress of hauling during this busy time for rodeo families. We will never go without these supplements for our horses and have tried many on the market. Thanks, 100X Equine!!!
Leslie B.
Cisco is 20 and a great trail horse! Riders best friend. Nothing he won’t tackle and particularly happy if he gets to jump a log! He has a bum shoulder, arthritis, but he would never tell you that!! He has been on this combo osteo-max and gut-x! Doesn’t skip a beat!! I have 3 horses on it. Great product.
