    SmartFlex® Rehab Pellets is rated 4.5 out of 5 by 271.
    Rated 5 out of 5 by from Very happy with it. My horse definitely noticed it, and was hesitant to try it but for only a few seconds. I do believe this helped improve my horses healing time. I know it gave me reassurance that I was helping her out.

    Rated 5 out of 5 by from It really works! I was skeptical at first, but this product was recommended by a friend. My horse was lame, but after a few weeks of rest and SmarkPak Rehab added to his feed, he is now sound and back to work. I am amazed and grateful! I plan to keep him on it.

    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!!!

    Rated 5 out of 5 by from Really works, impressive results! I purchased Rehab pellets last month for my 12 year old Standardbred who had suffered a tear in a stifle ligament last November. He was just getting better when he went off on the right. The vet said it was muscular, There was no change after two months following the protocol , in fact he was getting worse.I felt it was time to try something to supporthealing, his joints and muscles.Within two weeks of starting with the rehab pellets he was moving a lot smoother. One month into treatment and he's remarkablly strong and tracking straighter and feeling and looking like the horse I would teasingly call " Mr. Hot stuff".I only wished they made this product for people! Wow!

    Rated 4 out of 5 by from Quick results I bought this product after my QH mare tripped and came down in both front kness from the canter...had stovepipe right front leg next day. Now, after almost two months of lay up, hosing, and 25 days on Smartflex Rehab, she is back to 90% use!

    Rated 5 out of 5 by from Helping my boy recover! I'm so glad that I decided to put my older boy (17) who injured his S-I joint about 6 months ago. We tried multiple things for him. He didn't notice him get much better until this supplement. On this supplement he has been recovering very quickly! In about a month we can start trotting him again. I absolutely love this product, the vet told us how surprised she was how quickly he's been recovering since we started him on this supplement.

    Rated 5 out of 5 by from Amazing supplement! My 25 year old TB pulled his deep flexor tendon and had been lame and had heat in his leg for almost 3 months with not much improvement even with stall rest/sweating or wrapping. I started him on this supplement 1 month ago and he is now pretty much 100% sound and has not had heat in the leg for at least 2-3 weeks now. He no longer is in pain and back to his full self! With his age I had accepted he might never be 100% but now I believe I will be back to riding him in the future!

    Rated 5 out of 5 by from Great during recovery! Almost 2 years ago (in July 2013), my then 10 year old Dressage horse completely tore his front suspensory ligament. At that time, I put him on the SmartFlex Rehab Pellets not sure whether they would work or not, but I was willing to try anything. After 6 months stall rest (January 2014), I opted to do stem cell therapy. The vet gave him 8 months to a year to recover from the therapy with no promise of complete soundness. By July 2014 (only 6 months) he was given the okay to begin walking therapy under saddle. By September 2014, we were trotting, and by December 2014, we got the okay to enter full work again. He is completely sound now with no visible scar tissue over his suspensory on ultrasound. We went to our first schooling show in April and won our class. We are now riding in clinics and preparing for our first rated show in a couple of weeks. I believe the Rehab pellets gave him the extra support he needed to shorten his recovery time and ensure his ligament healed successfully.

    Rated 4 out of 5 by from So far so good! Happy horse! I bought this in Sept 2014 when my 15yr old competitive HJ mare was diagnosed with a medial collateral tear and a lesion on her lateral collateral ligament on the right front. We did stem cell therapy & shockwave therapy. I originally had her on Smartflex Senior, but once diagnosed switched her to this supplement. She's been on strict stall rest since September 2014, and now 7 months later, still on stall rest & daily hand walks. She eats this so willingly, and when I take her out for walks, she doesn't come out stiff or short strided. She has a very long flowing swaying walk, almost to the point where I have to half halt her frequently because she's walking faster than I. I really like the collagen & silica in this product, especially with the injury she has, along with the joint agents too so she doesn't get stiff on strict stall rest. I think a combination with aggressive veterinary treatment, therapeutic shoes and a great Farrier, the SmartFlex Rehab and the BOT bell boots I got(from Smartpak of course) have all been a contribution to her rehabilitation. I will likely keep her on this product until we start cantering much later this year, then eventually switch over to SmartFlex Combo Ultra which has the Smartflex III ingredients as well as the coat, gut & hoof ingredients...win win there! I will always have her on a Smartpak supplement from now! on.

    Rated 5 out of 5 by from Helped post-op Hock Chip Removal One of my lesson horses slipped coming off the ramp after the last show of the season - creating 5 chips to be removed from his hock. After his surgery we injected the joint and he had a reaction to the injection. I was getting nowhere with the swelling until we added SmartFlex Rehab to his diet. The swelling started to go down and I feel like it really helped speed up his recovery. He was able to make it to the first show of the season, and do Intro Level Dressage and WIN! He got two first places and High Point with a U12 rider!

    Rated 4 out of 5 by from Helping him heal Three months ago my horse pulled a tendon. He refused to remain confined and broke out every chance he got. When we managed to keep him in, he paced constantly. He wasn't healing or resting. We finally released him back into the pasture and I added Smart Flex Rehab pellets to his diet. After two months there is s noticeable difference. He no longer limps at s walk and seems much more comfortable overall.:)

He's been on the Rehab pellets for 6 weeks now and the joint swelling and the stocking up have completely resolved, and he is SOUND! SmartPak rocks!
