    SmartFlex® III Resilience Pellets is rated 4.6 out of 5 by 517.
    Rated 5 out of 5 by from Bought this a few months ago for Magic, thinking just to see how he did. He has been off since late winter/ early spring for various reasons, the most recent injury being swelling in his tendon around his fetlock. Now being on this and having the summer off, Magic's legs are looking better then ever!!

    Rated 5 out of 5 by from Works very well for my older horse. My 21-year old mare is still going strong because of this product. I was going to retire her as her aches and pains of age and arthritis were taking their toll but she has a new lease on life with this product! I noticed a difference the 1st week, but then it took a few more weeks for the full benefit to kick in.I wish it were less expensive but you get what you pay for. The palatability question is funny (in my case) because this mare will eat anything.

    Rated 5 out of 5 by from It works! I'm not sure why I doubted this product and waited so long to put my mare on this. The SmartFlex lll has really helped her flexibility and lengthened her stride back to what it was before she injured herself.

    Rated 4 out of 5 by from Works well but... Works well but I would prefer a pelleted version. While my horse chokes it down if it is well hidden he tends to ignore his grain if it isn't. I love how his coat looks but my horse isn't terribly thrilled.

    Rated 5 out of 5 by from Flash is Flexible Again Our rodeo rescue had an injury 3 years ago. We have had him for two years and one of the most important improvements has come from using SmartFlex Resilience in his rehab program. Over a period of three months we could see him improve weekly. I continue to keep him on a smaller scoop because I know it will keep him in great shape and more comfortable.

    Rated 1 out of 5 by from Not for my mare! I bought this to help my mare with her joints. She refused to eat it. It smelled very strong and the pellets are large. So you cant hind them in her food. Even tried putting molasses on them. She just spit them out.

    Rated 4 out of 5 by from My horse has spunk I have been using this since winter has ended, I started to work my 14 year old Quarter horse a lot more with dressage and jumping. I wanted to have something that help him feel young, and boy does he! He acts like a 4 year old not a 14 year old! He is a lot more fit then he was last year and I think this product helped us get there.

    Rated 5 out of 5 by from Great product I've used this product with soft tissue injuries and it seemed to provide nice supportive care along with veterinary treatment. My senior mare also seems to enjoy it with decreased stiffness and a noticeable increase in range of motion.

    Rated 1 out of 5 by from picky eaters beware! I love Smartpaks but the Smart Flex III Resillience pellets and the Smart Pak Electrolytes are not for the picky eater. I am on month 2 and am still trying different "tricks" to get my mare to eat the two months supply that I bought. So sad! I can't review how they work - YET!

    Rated 5 out of 5 by from Fantastic Results! I started my 7 yr old TB gelding on this supplement last year. I can't say enough good things about it. Before the supplement, he experienced a lot of stiffness behind. I wanted to steer away from any further injections, and was looking for a long term solution. I researched different supplement options from Smartpak and found the SmartFlex III Resilience to be the best option. After two weeks of use I noticed a big difference in my horses trot. A year later and he is still doing awesome! He is now able to extend his strides and move about the dressage ring with ease. This is the only supplement he is on and I'm thankful for a great product, at a reasonable price, and happy to have done away with injections.

    Rated 5 out of 5 by from Great product that supports joints and tendons I wanted a joint supplement that both supported the joints and tendons which this one has it all. My mare bounced back from a tendon injury and this supplement insures she has the right amount of protection she needs to keep her legs healthy from the inside. Absolutely love this and my mare eats it up.

    Rated 5 out of 5 by from It is working! I bought this in April after having my 10 year old horse diagnosed with arthritis. He was off. Started on Smartflex III and he seems to be much better. I have not had a limp issue since we got him started.

    Rated 3 out of 5 by from My Horse Refused To Eat It :( Unfortunately, my horse absolutely hated these pellets, no matter WHAT I added to her food to try to hide the taste of the pellets she wouldn't touch it, which sucks because I'm sure it would have been great for her, SmartPak makes wonderful supplements that really work.

    Rated 2 out of 5 by from Not seeing any improvement One of my horses wouldn't eat it, the other two aren't thrilled and I haven't seen any improvement in their going (still have issues with stiffness) so I'm switching back to my old supplement.

    Rated 5 out of 5 by from Comprehensive joint supplement Started my 13 yo TB gelding on this supplement after finding out he has arthritis. It has all the expected ingredients for a joint supplement at high levels plus vitamin c. I was able to eliminate some other supplements and no longer had to add to there.

    Rated 4 out of 5 by from Works great!!! But... I noticed immediate improvement after only using for 1 week! But, my horse wouldn't eat the supplement in his grain so I had to add extra enticers (cereal) to it.

    Rated 5 out of 5 by from Happy Joints Bought this product couple years ago to help my mare repair and heal from injury. It worked so well to return her to musculoskeletal health, I've recently started another horse on this product to help protect his joints from the wear and tear of a busy training and AQHA show schedule. Horses also eat this product without hesitation.

    Rated 5 out of 5 by from Great Product I started an OTTB on this a couple of months ago. He is only 6 now but ran a lot of races in just 3 short years. I took him in as an eventing project and when he first came to me he was very short in his stride, not much energy and his feet needed some work. 6 months later he has an overstride and he runs and bucks happily when turned out.
