Gut-X got my older horse off of Ulcergard ! And Osteo Max has eliminated the need for stifle injections on my younger horse. Both horses are on both off these products, plus Max Calm every day. Love 100X Equine

My mare was lame when I got her and thin. She has been on your product now since January and has improved in weight, doesn’t limp anymore and has a foal at side. I love your products for horses and dogs!
Amanda B.
I have already said all in my video. This is an amazing product…. Love love love it. I certainly would not be without both gut x and osteo max. My old horse has leg issues and cannot take pain meds because of his gut. I definitely need your products. Thank you 100 Equine
Toni M.
YES! My girls, ages 33 and 34, are thriving with support from OsteoMax and GutX! They’ve been on both products for over 3 yrs, and look & feel half their age. Both products made a significant improvement in their well-being from the get-go — and they ‘re at the top of my list for supplements!
Karin C.
I love all the products.

My 11 year old Hanoverian Desi has always been a harder keeper, had a poor top line, tight in his back, an over thinker who
worries and gets spooky, and has had a weak left stifle that can be sticky. He has been on your supplements since early last winter 2025. He is on GUTX, Osteomax and max calm. He looks better this spring than he ever has! He has developed some top line, is calm and relaxed in his work, better traveling,
and is moving better then ever! Your team checks in regularly to see how he is doing and
has helped me with dosing and a plan for
Stressful traveling. I couldn’t be happier with your products and the support you provide! Thank you for all your dedication to these
Fragile 1400 lb creatures!

24 and 26 years old! Still going strong thanks to GutX and Osteomax!

Man I don't even know where to start! We have been using 100x products for 3 years now but just started the max calm with my 5 year old filly and WOW WOW WOW what a difference it has made! She went from always on edge and anxious to calm as can be and so affectionate now. She is also on gut x and osteo max. We love 100x products and will be customers for life

I used Osteo Max before with my gelding Gabe who is now almost 30…. This year he started to go downhill after having a leg injury. Even with great vet care and premium feed/hay and alfalfa it was not looking good. Several years ago, I used Osteo Max and loved it and overtime I stopped re-ordering…. I was running out of options and saw an ad for Osteo Max and GutX. I instantly ordered it again. It made such an amazing impact on Gabe. He’s been back on it for approximately five weeks and has rebounded. I will never stop using it again. I truly believe that it helped save Gabe’s life. My neighbor who has helped with this journey is amazed at what the product has done for him I will update in a couple of months with another picture as every day is a improvement for him I can’t thank y’all enough for this wonderful product

Second time ordering GutX and osteo-max. Noticeable improvements in all horses.
Linda L.
I have used GutX and Osteo Max since you started the company. We got free samples at the Mid Atlantic Reining in Lexington,Va. After I used it I loved it and my horse was amazing. So I don’t need to take a picture or tell you how great it is because I am an original user. Thanks for making it. Linda H Leatherwood.

I’ve used it on two of my ranch/cowboyin horses now. The first one made a believer out of me so I started using it on another one. Great stuff, multiple benefits!
Cierra S.
Started my 24 year old gelding on gutx and osteomax and it has done wonders for him. He is keeping weight on now better and he is running around the pasture again. Since I have started my two mares on both supliments and couldn't be happier with the results. I will always be 100x customer.
Courtney C.
I absolutely love Gut X. It has been such a great tool for overall health and has made a giant impact in helping build and keep top lines as well. I have a hard keeper 25 year old stallion on it and within 4 weeks he looks fabulous and has a great shiny, slick coat as well! Just started him on the Osteo Max and if it’s anything like the human version they offer(which I use and it’s helped a ton) I’m expecting great things for his joints and laminitis as well!
Lisa P.
I have 4 horses all on Osteo max and gut x and I think the product is awesome it’s easy to feed and I feel it helps my horses a lot. We travel to events on the weekends the gut x really helps them feeling great with all the travel and the Osteo max is a bonus keeping everything else moving as it should!
K8m D.
Our 26 year old Dutch warmblood and pur 24 year old breeders stock paint horse have done FANTASTIC since we added GutX and Osteomax to our array of supplements. I cannot say enough good about these products as they have turned our old horses around. Easy to use and very palatable for our picky eaters. Cannot recommend them enough!
Shara B.
My 27-year-old gelding continues to do awesome on the OsteoMax and the GutX. And, your periodic specials of "free 1/2 gallon with purchase" are always great! Thanks for the amazing products and your customer service!

I purchased my mare in 2024 from an animal rescue. She was malnourished, her hair was dingy, and she clearly had ulcers. She also had some issues with her hind leg. I started her on GutX and OsteoMax. She has been on these supplements for two years now. She has transformed into a completely different horse. Gone are the limping issues or stiffness. Her coat is healthy and shiny. She has gained muscle mass and zero issues with ulcers. I would highly recommend this to anyone. Great products!
Dan S.
I love Gut X and Osteo-max! The results I have seen are amazing. My horses are happy and I can tell they feel good. There coats are shiny and smooth.
Rachel W.
We love our 100X products! I use the Osteomax and GutX on my show gelding and the Max Calm on my mare that is a nervous Nellie! All products have made a big difference!
Anna B.
We have garyella on osteo max and gut x and she's doing great. She's 19 .
Tammy P.
We placed our horses on OsteoMAX and GutX at the beginning of this year. They look amazing! Other people have noticed and inquired about the supplements they are taking. Their top-line has significantly filled in and their coats are shiny. They are 20 and 21 years old and look very healthy.

Hope everyone took advantage of the memorial day savings I sure did. Picture is my girl Kat she is on osteomax, gutx, Amino max and now calm max . So is my 31 year old girl Annie. Love these products.

The product was recived on time and I was made aware of all delivery information.
becky t.
I’ve seen wonderful improvements in one of my horses. He always seemed a little stiff and like he was sore I put him on this. He’s great. His attitude has calmed down and he writes beautiful.
Because of that I started giving one of my pregnant mirrors it because she seemed a little sore in the hind end and now she’s moving around Great after being on it for two weeks
DIANA T.
Fast delivery. I'm looking forward to seeing if these products have the desired effects

This is my 34 yrs old Criollo/Peruvian Paso mare, Coco Chanel No.5. At age 23 she was diagnosed with arthritis in the shoulders, hips, and knees. We tried different feed supplements, Legend injections, and lots of Equioxx to try to keep her comfortable and moving. Every winter I’m sure it will be her last as she’s just so uncomfortable and off. I heard about Osteo-Max and researched it. I dreaded this winter and decided to give it a try. All I can say is this is the very first winter in at least 10 + years (probably more) that she’s not limping, she’s not off or favoring any legs! Day before yesterday, she objected to my spraying her scratches with antifungal, pushed through a gate, and took off cantering and galloping up and down all the hills surrounding the barn for a good half hour before letting me catch her! I saw it with my own eyes…she has offered to canter very occasionally the past few years, but it’s in the mid 20’s in the dead of winter and she was freely cantering and galloping around like she did 15-20 years ago!! IM SOLD ON OSTEO-MAX!!! Thank you!!

I justa want to share with you all another BENEFIT of GUT-X . My senior (20 and rescued) came with a huge sinus infection due to 4 bad teeth. This was going for almost a years ( I was told by the rescue place) . We removed his tooth we gave him antibiotics and bute , the infection was gone but it came back and again antibiotics and bute , etc . During this whole time I doble the dose of GUT-X as a wall stomach protector ! I don’t know if everyone knows but bute reduce the formation of the mucus in the stomach and the acid then damage the walls producing ulcers ! So GUT-X IS A MUST HAVE DURING THIS PROCESS! It saved his life ! Sometime we can see the changes from the inside , but it only take a happy HORSE FACE to see the results ❤️ thank you Gut-X
Samantha M.
In july of 2022 my mare suffered a deadly jaw fracture that required surgery and ICU Care for 90days at a rehab facility with round the clock care at her 12 week xrays revealed little to know healing her care team recommend adding 100x products ontop of light therapy and that's just what we did from late October to January 5th her xrays revealed the Jaw was healed and her vet team at rood and riddle equine hospital was over the moon just couldn't believe her xrays and removed her implants as they was causing her major discomfort she will continue to stay on 100x products while she recovers from her 2nd surgery

I have been using these products for 5 months and have noticed a difference.
Jason G.
My horse has been lame on the left hind for over a year. Nothing has seemed to help, we started this osteo max 3 weeks ago and we have seen a huge improvement.
Lisa B.
Started using about 3 weeks. Have seen a change in my moms horse. Shoulder issue n moving better
Debbie S.
I have a clients horse here who had a thyroid issue in may then a metabolic founder. They have done all sorts of medicine and 3 sets of corrective shoes and she is still lame. She has been squared back on her haunches that she even developed a string halt reaction. I read into this product and talked it over with the vet who said YES try it. Well 3 weeks into the GUT X and the OSTEO MAX she is walking almost normal and the string halt is almost gone. She gets better everyday. I am so in love with this product. It is definitely a life saver. Thank you so much for this amazing product.
Phillip L.
It is still fairly early to tell but I think it has helped both of the horses I have it on. Osteo max for my 10 year old race horse and GutX for a 22 year old.
Lisa M.
My 13 yr old partner has been troubled with soreness in his front feet for the last few years. I have tried several things over the yrs trying to help prolong his barrel racing career.
Only after a couple of weeks on Gut X and Osteo Max it is amazing. No more walking out of the stall stiff. He is moving like he did yrs ago!
Rick C.
18 year old heeling mare with swelling in knee, 30 days on osteo max and is staying in the ground now as I dally
Elika S.
I bought Gutx for my mare with decal water syndrome. I have tried almost all supplements for this condition and nothing worked. It took about two weeks and now my mare’s rump is clean! I’m so thrilled with this product.
I also bought OsteoMax for her. She’s been on/off lame due to an old tendon injury. So far, so good. I need more time to see if there’s any improvement.
Erika S.
Horses are eating both products, the OsteoMax and GutX. I'm feeding the Osteomax to my 2 year old up and coming racehorse and her tendons are always cold and tight! I feed the GutX to my seasoned 4 year old racehorse who is prone to ulcers and she has been behaving well so it seems to be working!
Kelly B.
I have noticed a big improvment with my horse after being on both Osteo-Max and Gut X
She feels great to ride and is so much happier from being saddled to enjoying being riden.
Josey P.
My horse has been on both products for 3 weeks, and I have seen a huge change in him. He is more mellow and willing to work with no fuss.
Leigh H.
My colt has been on these products for about 2 weeks, he is looking great!
