    SmartFlex® Rehab Pellets is rated 4.6 out of 5 by 262.
    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 5 out of 5 by from Great product Started using this product a few months ago and after a few weeks I could see a huge difference in my horse's soundness-she has some arthritis and a previous ligament tear.

    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!

    Rated 5 out of 5 by from Great Products I am anxious to see how these help my gelding recover from his tendon injury
    Date published: 2015-10-23
    Rated 5 out of 5 by from Very pleased with this product. My horse suffered a mild strain of his high suspensory ligament, my vet initially said he would be laid up for six months. After 3 weeks of smartpak rehab, the vet rechecked him 30days from the initial diagnosis and said that he was healing so well that he would give him another 45days of rest, recheck, but feels confident that he will be able to return to light work. So that would be just over 2.5months rather than 6months. My horse and I are thrilled about that! He has also been living in his Back on Track quick wraps, so they may deserve some of the credit for the healing too. I just purchased a second bucket of SmartPak Rehab to continue him on it while he recovers and starts back to work.

    Rated 5 out of 5 by from AMAZING RESULTS Our 19 year old AQHA gelding "Goodnuff For The Blue" AKA Cactus has been on the Smart Pak Rehab supplement now for almost two months after he obtained a major infection in his joints causing him to walk on only three legs and made his white blood cell counts sky rocket greater than our vet has ever seen. Our vet told us that most horses never live after an infection this bad in the joint. We were advised to consider "other options" but Cactus still looked like he wanted to fight so I spoke to one of SmartPaks great customer service guys and he suggested this rehab supplement along with the nutrition diet I had already set up for him. We went to the vet yesterday to get his cast off his front leg and the vet was VERY surprised at his progress and how well he was walking along with how well he has kept up his body condition. I have to say this supplement had a lot to do with his progress and he will continue to stay on this till he is fully recovered. He actually gets to go back out to pasture in one month he is doing so well and its been three months since the injury. Thanks a lot Smart Pak and Smart Pak Team!!!
