    SmartFlex® Rehab Pellets is rated 4.5 out of 5 by 271.
    Rated 5 out of 5 by from Condylar Fracture of Cannon Bone My horse took a jump into the ditch while I was running him and he came out lame. I had no idea what was wrong.....took him to first vet to get X-rays and she found nothing (Lack of Experience) My horse was lame for months and i figured it was his splint bones, tendon or suspensory ligament. So I did my research and gave this supplement a shot. Months later my horse was doing okay had no problem walking, trotting, cantering. I was trimming his hooves and noticed that he had leaned on me a lot more when I picked up the uninjured leg. Ended up taking him to a specialist and behold condylar fracture of the right front cannon bone...I was very mad at the lack of knowledge from my previous vet (also saying I could ride him in December when this happened in October), and very distraught. The Vet was amazed, he had worked on racetracks his whole life and has seen these fractures before many times but never saw one that was healing perfectly on its own. I did a lot of research and found that many ingredients in this Rehab formula are building blocks for bone regeneration. Bone doesn't heal it regenerates. 720 mg of Silica, 1,500 mg of collagen, Chondroitin Sulfate, Hyaluronic Acid all building blocks for bone regeeration. Plus it helps the joints out tremendously. I truley believe that this supplemtn played a huge part in keeping my horse sound and can't wait to take the next set of xrays to see how much it has healed. I already ordered more of this supplement besides having him on dicalcium phosphate. In pellet form this goes right in my horses normal supplements and he doesn't even notice it. Eats it all and hes a picky picky eater. Not fond of the DiCal.....lol

    Rated 4 out of 5 by from Seems to help a bit My horse has been laid up for months with a collateral ligament injury, and after reading the description on the SmartFlex Rehab pellets, I thought it might do him some good. It's a little expensive, but I do think it makes him more comfortable than if he'd been without it, and he seems to be recovering well, despite being given a pretty depressing diagnosis. Not sure if it is a coincidence, but I think this has really helped my horse.

    Rated 1 out of 5 by from My horse is an extremely picky and suspicious eate I have tried the SmartFlex Rehab Pellets for the past month or so. I have tried one packet, a half packet, a half packet, a table spoon and then a mere teaspoon that aired out to reduce the odor for 12 hours, for 24 hours, and for a whole week mixed in with approximately 7 cups of oats. If there are even a few little pellets mixed in with the grain, my horse walks away from the grain bucket and won't eat anything. I am certain that this is a good product, it is just that my horse will not eat his oats with the product in it. I recommend it to others to try as a well researched and well balanced product that is a good value.

    Rated 5 out of 5 by from Only Supplement I'll Use I first started my TB on this supplement when she slipped on ice and tore through 3 different ligaments and tendons in her left hind as a 13 year old. One vets opinion was that she would never be more than pasture sound. It took over a year and a combination of therapies, but she was jumping around 3' courses comfortably. We were even able to do the occasional 3'6 without soreness issues. There is still a disability in that leg (has a difficult time with lead changes), but she is 100% sound. I took her off the supplement and switched to a lighter version for her semi-retirement. The difference was slow onset and I thought her age was starting to catch up to her. She was reduced to light riding this past summer and almost full retirement due to her discomfort and stiffness. After a year off of SFR, I decided to give it another try. She has been back on it for 2 months and my now 20 year old TB is acting like her 12 year old self again. The difference is HUGE. I will not be switching her off this supplement again!My mare is a horribly picky eater and will not take bute in any form or any way. On other anti-inflammatories she just goes completely off her feed. She LOVES this supplement and I have never had any problems with getting her to eat it. It does have a stronger smell and I can't imagine the taste is much better. My thought is that it is from the Devil's Claw, which some horses are fine with and others don't want anything to do with it.

    Rated 3 out of 5 by from I got this because my miniature horse got hurt from a goat , I had him on Finish line with Ha , I called to see what product to use for him that may be better then Finish line with Ha they said the SmartFlex Rehab pellets , well he hates it I have to force him to eat it, the smell is awful. So I called to stop it , I'm going back to the finish line , with it he was even trotting, with this he is limping still bad.But that don't mean it won't work on your horse.If you caqn get them to eat it.

    Rated 5 out of 5 by from Switched back!! I had been using this for the past 6 months with good results on my 6 yr old with difficult stifle issues- some ligament issue with secondary joint soreness. He had PRP in August too and then became sound. My older guy was changed to HylaSport and I thought I would try my younger on it too, but within a week, he was worse. I immediately ordered the Rehab formula again and will keep him on this. I should not have changed. Lesson learned. Sometimes you don't know something is working until you stop using it.

    Rated 5 out of 5 by from So far so good! My aging WB has issues with soundness. So far this product seems to have given him some mobility back. It has only been a month. Time will tell.

    Rated 3 out of 5 by from Unsure of long-term benefits, yet Excellent ingredients and wide range of needed nutrients, but cannot testify towards the effectiveness of ligament/tendon rehab, just yet. My gelding, who suffered a suspensory tear in February, was starting to heal up in Sept-Oct, but then started degrading again. He started this supplement in mid-late October and it is only early December, so holding out hope on the supplement's success. No signs, yet; he is still off on his stride and the leg gets puffy with any amount of trotting.

    Rated 4 out of 5 by from Helped a lot though horse does not like They smell gross to me and my mare does not like the taste, but she was overcoming a tendon injury, and so I crushed them up and hid them in some bran mash making her eat them when she would not eat them with her other feed. I believe she healed faster because of this product. It is a good quality product.

    Rated 4 out of 5 by from Vet noticed a difference Bought this for my friend who's horse had a suspensory ligament injury. Another horse at the barn also had same injury.

    Rated 2 out of 5 by from Not tasty Unfortunately my horse refused to eat the supplement and after not eating his food in protest I had to stop giving them to him. I tried molasses and everything. As soon as I stopped he went back to eating his dinner. I'm sure they are great but I was unable to get my horse to try them. Thanks for the refund!

    Rated 5 out of 5 by from decreased inflamation Noticed improvement in swelling as soon as 3 days after starting. She had a suspensory problem. I had tried another product but no noticable change. I loved the smell of it and she loves to eat it with her oats.

    Rated 5 out of 5 by from Awesome! My horse has DSLD and both back suspensory ligaments are severely dropped. He has always popped and cracked when he walks. I recently started discussing my options with him as far as how much longer he may have (mainly due to the fact that he was dragging his back legs and starting to trip more). As a last resort I decided to start feeding the rehab supplement and to my amazement he's walking around SO much better! He barely cracks now and he seems to be more willing to move around :) I'm very happy with this product. Although I know there's little I can do for his condition, I'm happy to know I can help him feel better.

    Rated 5 out of 5 by from LOVE THIS!! I recently purchased this product for my 5 yr old OTTB mare that had sustained a small fracture on her knee while running and was lame. After using the product for 60 days I saw a tremendous amount improvement in her movement and is more comfortable. I would highly recommend this product and would use it again.

    Rated 4 out of 5 by from i believe there is a difference; will update just started my Extreme Mustang Makeover Mare, that i was so very fortunate to be able to purchase at the event, on this product. yesterday and today, i realized she was much more comfortable because she allowed me to groom her croup, hips and glutes and didnt try to politely step away from my reach. i do believe it is all the anti-inflams in the product working to relieve some issues from training and competing. the competition is very hard on this Mustang as they have had nothing done with them since capture. happy to say i am looking forward to continued comfort for her.

    Rated 5 out of 5 by from In just 5 weeks... I bought my mare on February 17th of this year. One month later she was off with desmitis of the upper suspensory and some minor fraying of fibers. Not a terrible diagnosis, but still 8-10 weeks off with a round of shockwave. Vet shockwaved her almost exactly three weeks ago, and while obviously that helped a lot, he was amazed to see how good she looked today on the lunge line and on the ultrasound! 5 weeks later and we are walking under saddle :) Vet said to "keep on doing what you're doing" and I believe part of that is using these pellets! He also said she looked a lot better health wise and I have smartshine, smartlytes, and and U-gard to thank for that too! Also, special thanks to customer service rep Eden for all her help on the phone after Adeline's initial injury. She was so kind and helpful.

    Rated 5 out of 5 by from Really works! I had my horse on this for about 3.5 weeks and she started to show a lot of improvement in her general flexibility. Went from being nippy about being touched to calm.

    Rated 5 out of 5 by from Serious Injury In the fall of 2015 my 2 year old mare seriously injured herself breaking a wooden post and dragging it. She both seriously sprained her knee and in the same leg sliced her deep and superficial digital flexor tendon right under the fetlock. The vet says it wasn't a complete tear (obviously or else the outcome would have been much worse.) Though it was iffy for a long time if she would ever be sound again. I will definitely recommend SmartFlex Rehab to any of my horsey friends after using this. Both our vet and I say these had to have helped, because even though she didn't start getting these till the wound was closed it did help her soundness and recovery. 4 months on these and the severe swelling is now gone. No other treatment besides these. No bute. You couldn't tell now just by looking at her that she almost became a pasture ornament a season ago.

    Rated 5 out of 5 by from Excellent supplement! I received this supplement for my 11 yr old quarter horse gelding on 3/3.. starting feeding in his daily feed that day... I'm amazed at the results I'm seeing! Amazing supplement! He had an older hock injury that would leave him stiff some days with minor swelling. He also had mild partial facial paralysis on the right side. Not only is he moving around better with no swelling at all but his facial paralysis has almost completely subsided! I'm thrilled with the results so far

    Rated 5 out of 5 by from Well - My Horse Is Sound Now My horse had been lame since September with a suspensory injury and EPM. I changed him to the SmartFlex Rehab pellets in January and he trotted out sound for his next check up! I'm seeing a big improvement in his soundness and recovery using this product.

    Rated 5 out of 5 by from Finally, a product that makes a difference! Very rarely do I support spending money on things that go in my horse, and out the other end. BUT, I truely think this product has made a difference. The vet couldn't believe how fast my mare was healing and rebuilding after her severe hock injury. I happily spend the money on this supplement!
