    SmartFlex® III Resilience Powder is rated 4.6 out of 5 by 221.
    Rated 5 out of 5 by from Starting to notice a change Started giving this to my mare a month ago and am beginning to see a change in her. She's a 15 year old ranch horse and was roped off of/ridden heavily, which gave her some arthritis. I'm already seeing a change in her personality and she seems much happier! The only thing I have noticed is she doesn't like the powder, but I just mix apple sauce in her grain and she gobbles it up.

    Rated 5 out of 5 by from Honestly a miracle. Been using this a month and a half now. my horse has pulled all four suspensories and severed his extensory tendon in his right hind. originally he had extreme swelling in all four legs, stiff joints, and all around unhappy. now only one leg is slightly inflamed and he is happily performing at fourth level.

    Rated 5 out of 5 by from Recommend My reiner has been on this for about four months and it seems to have made a difference in him. He feels better, moves out more, and isn't so stiff when being brought out of the stall. My trainer says that he has been riding better than ever before (owned him one year) and thinks the credit goes to the supplement!

    Rated 5 out of 5 by from great feature My trainer insisted I start SmartFlex III Resilience before my thoroughbred went back to the track--if he said to use it then it must be the best for joints!

    Rated 4 out of 5 by from Quality product but did not help my situation As with all Smartpak products, this supplement appeared to be of excellent quality and was always fresh. I did not notice a huge change in my horse with this product but his main issue is a bone spur in his hock so perhaps it wasnt the best fit for him. He was on the product for about 4 months. On the plus side, my horse is a bit finicky about his food and never seemed to mind eating this supplement!

    Rated 4 out of 5 by from Good But Not Perfect I have a horse with bone on bone contact in both of his stifles and hocks from racing and since I have put him on this supplement I have noticed a difference in his willingness to work and his attituce when working. It is not perfect because he still has some bad days where he doesn't want to do anything, but I think if I combined this supplement with injections he would be significantly better off. Overall the product has worked very well for a horse with racing wear and tear and I would definitely recommend this product.

    Rated 5 out of 5 by from So Far....Lovin' It! I've been feeding my 20 yr old OTTB this supplement for about 40 days now. I'll know better in time how much it's helping but for now it seems to be working quite well.I desired to get him on something that was comprehensive for joints...so many of the supplements contain glucosamine and chondroitin but not MSM, or contain MSM and glucosamine but not chondroitin. I was thrilled to find SmartFlex III Resilience. It contained everything I was looking for...and in doses that seemed as though they might actually make a difference (also difficult to find).Naturally, I love the convenience of SmartPaks. How does it get any better than peel-it-open-and-you're-done?!!! When I ordered the first batch, I ordered the powder. My horse wasn't too thrilled about this but wouldn't you know it, Smartpak called me before my next shipment to see how things were going. We changed to the pellets and he gobbles them right up. How cool is their customer service?!!I am reconditioning him at present and had noticed lots of crepitus in his joints as well as a lack of fluidity to his movement prior to starting SmartFlex III Resilience. After about 40 days on Resilience, I am thrilled to report that his fluidity is better than I've seen in years! He has spring to his trot and a forwardness that has been lacking for some time. In fact, I was so awestruck by how beautifully he was moving, I kind of forgot to pay attention to where my lines were, where my whip was, etc.I suppose I will update with another review after a few months and once we are back to under saddle work, but for now, I am VERY pleased with the results of this product. I can't wait to see what else is possible!!!!Thank you Smartpak for excellent customer service and a great product!!!

    Rated 4 out of 5 by from Keeps Us Going! I recently put my horse on this supplement as a precautionary move, although he did not have any issues at the time. Even though I didn't think we had any joint problems prior to using the supplement, it has helped him quite a bit as well as other horses in the barn!

    Rated 5 out of 5 by from Best joint supplement I recently put my 8 yr old gelding on SmartFlex resilience 3, a step up from SmartFlex 2. He's in a moe vigorous training program now and on cold mornings was showing signs of a little stiffness, he also has had a small click on his back fetlock for sometime. Wanting to be ahead of the curve I decided it was worth the money to try the step up. Within a week the stiffness in the mornings was almost non-existent and the leg click is almost gone.I would recommend to anyone wanting to prevent injury and maintain health!

    Rated 5 out of 5 by from Seems to Be Very Effective I use this on my senior horse - after the first two months it seemed to really make a difference and was far superior to any other joint supplement I had tried and doesn't seem to bother his sensitive stomach.It's pricier than a lot of other joint supplements, but in my opinion, worth it.
    Date published: 2012-07-31
    Rated 5 out of 5 by from Amazing product My horse was becoming stiff in the hocks and would continuely crack and pop his joints. I noticed a lot of people in the barn using this product and I gave it a try. There is no longer stiffness in his hocks and the pops and cracks are barely there anymore. I love it.

    Rated 5 out of 5 by from Great Joint Supplement I use this supplement on 3 competition horses that are in moderate to strenuous work and love it. One horse is on the mend from an injury and does very well with the SmartFlex III Resilience. Another horse is a hunter jumper and we like it to maintain her. An additional plus is they enjoy eating it in pellet or powder formula.

    Rated 5 out of 5 by from can't believe the results i've only had my brandenberg on this for about a month and a half now, and i'm astonished by the results. i've tried him on cosequin before, and not many results had shown, except maybe he wouldn't come out AS stiff. with the smartflex III resilience, pete has noticeably changed. he seems less sore in his workouts, recovers quicker from strenuous workouts, and seems overall a lot happier in his stall manners. i am so looking forward to what else this supplement will bring!!!

    Rated 5 out of 5 by from Best joint supplement out there! I have a half arabian that does everything so he has gotten joint supplements since he was four. He has always has wind puffs on all four legs, the only thing that I have ever found that takes the wind puffs down is Rapid Response. I don't like to feed it because it's made from shark cartilage and it has to be kept in the fridge. I recently tried him on SmartFlex III Resilience and it works even better than the Rapid Response! I am very happy with the product and my horse is too!

    Rated 5 out of 5 by from Great for Joint Health I adopted an Off the Track Thoroughbred less than a year ago. He sustained injuries on the track (some of which he raced on), including pins in one ankle & chips in the opposite knee, before being retired. My trainer jokes that he's a 6 year old youngster with an 80 year old body. All joking aside, my big bully needed a good joint supplement that would ease his arthritis & joint inflammation. When the weather turned chilly here in SoCal this winter, he was totally lame (couldn't ride him for over a month). I was about to retire him to pasture indefinitely. I've tried a few different supplements, since adopting him & nothing seemed to improve him much. Then I discovered that SmartFlex III Resilience has more Glucosamine, MSM & HA in it than almost all the other available supplements. My boy has been on it for over a month now & showed marked improvement within the first week!! He's doing flat arena work & light trail 3-4 days a week & shows no lameness, stiffness, or swelling in his joints before, during, or after his training sessions. He's much happier & relaxed as a result & so am I! My horse's trainer & vet were both impressed with the results. Couldn't have asked for a better product! Bully & I both thank you Smartpak!
