    Rated 4 out of 5 by from Tasty stuff My boy who's a very picky eater, seems to enjoy this on his grain every day. I haven't noticed a difference in the creakiness of his joints yet, however. It's only been a few weeks, but I'll continue to give this to him.

    Rated 5 out of 5 by from LOVE this product! This is the only joint supplement I have found to make a serious difference in my horse in a very short amount of time. Without Corta-Flx, he comes out of his stall very stiff in the morning. After starting him on Corta-Flx, 3 days into the loading dose he walks out like a champ. He will now gallop in the pasture with his friends and keep up with them - and he is 21!The pelleted form is very palatable - each horse taking this supplement will eat it right out of the hand.

    Rated 5 out of 5 by from Year Long, Lots of Progress Well, when I first bought my mare she started coming up lame. So she was seen by multiple vets, one being a lameness specialist. She was put on injections, and feed through. Corta Flx is the best feed through supplement out there. She's been sound and moving so fluidly since she's been on this supplement. It definitely gives her the extra boost she needs. It's inexpensive, palatable, and works great!

    Rated 5 out of 5 by from Good for picky eaters I use this on my TB who has mild arthritis in her hocks. I have noticed a significant difference after having her on this product.She's been on it for 4+ months, with Adequan and MSM. The combination works amazing for her.I was feeding the pelleted, but it is cheaper to feed the liquid. :)

    Rated 5 out of 5 by from Love This Product I have been a Cortaflex user for years on multiple horses. I have tried another brand that was supposed to be the same but the results stated otherwise!! My horses make faster, smoother, and more consistant runs when on Cortafelx. I just switched from the liquid to pellets. This makes life on the road much easier and not so messy in the buckets..my horses clean it up!!

    Rated 5 out of 5 by from Great Product - Recommended! I have been using this product on my retired A-curcuit H/J and my off-the-track TB in training and it is awesome! It does take a month or so to kick-in and see results but the results ARE noticable when it does! My vet recommended this to me for use on my guys from the retired Appendix to my now in training TB. It has worked great for the damage that has been done from the 5 ft fences & the prevention of future damage to my TB in training. I think the cost is good too considering some other products.

    Rated 5 out of 5 by from Maintanece Only Purchase I am using this product for a 3 yr old futurity hopefull barrel horse. It is being used as a maintanece only product so far, so not change has been seen since we started this product, but no change was expected either. Will continue to use as it seems to be a good product for the money.

    Rated 2 out of 5 by from Didn't seem to have any effect My 14 year old TB mare who plays low-goal arena polo has been on the Corta-Flx pellets with HA now for 3.5 months. I haven't noticed a difference in her gait, play, or attitude. In fact, she recently pulled up with a pretty bad soft tissue injury in her front fetlock (mysteriously by standing in her paddock?) and although she continues to eat the Corta-Flx the healing process seems pretty normal and slow (I also had her joint injected, applying Surpass, bute for the first week, handwalking). The pellet form, however, is very convenient to feed and she loves it with no palatability issues.

    Rated 5 out of 5 by from Highly Recommend I have used Corta Flx for many years for my horses suffering from arthritis. I recently put my miniature horse that suffers from Cushings,arthritis and chronic laminitis on this product. I noticed considerable improvement in his flexibility and movement one week after starting this product. He is down to getting bute once a day, instead of twice per day. Great product! Quick Results!

    Rated 4 out of 5 by from Decent product Corta-Flx is a good product and it does work. No problems with my horse eating this on his grain.I prefer SP Senior joint supplement and I think it works better for my horse than the Corta-Flx. Others at my barn really like the Corta-Flx. Just like any supplement it seems there some horses that do better on one and others that do better on another.I started to use the Corta-Flx when my horse stopped eating his SP Senior joint supplement (powder) but stopped when a pellet version of that product came out. I prefer the SP supplement over the Corta-Flx. However, this is a good product and worth trying.

    Rated 5 out of 5 by from Great Product I have a 19 year old retired race horse with a racing injury in his stifle. When he is on Corta-Flex he is noticiably more comfortable and has a greater range of motion in his left hind leg. He was doing so well that I tried taking him off of it, not a good idea, it really makes all the difference in his ride-ability!

    Rated 5 out of 5 by from Great Results I have had my Hanoverian mare on this product for 8 years. I have tried other joint supplements to see if I could achieve better results or find something more cost effective. She either did not show an improvement or would not eat the other joint supplements. She has done great with Corta-Flx and I highly reccommend it! My other mare I recently accquired has some arthritis in her hocks and she has shown great improvement since being started on the supplement as well! Great product!

    Rated 5 out of 5 by from Works great & quick!!! I absolutely LOVE Corta Flex! My 13yr trail QH started clicking in his front & hind limbs. I put him on the pellets after a vet recommendation. He is a picky eater & I was relieved that he loves it. After a week there was no more clicking & my boy was moving much better! I took him off for awhile to double check that it was working & he started clicking again. I have him back on the pellets & will definately keep him on them.

    Rated 5 out of 5 by from Best Invention I was originally using Cosequin as my mare's joint supplement. And it wasn't quite doing the trick. She is sixteen years old now, and is only just now showing arthritic signs. She is a driving pony, and when in hard work her joints, tendons, and ligaments get beaten up, so to speak. I just recently switched her over to Corta Flx and the clicking in her joints has gone away and she is moving better than she ever has.

    Rated 5 out of 5 by from Amazing results! Our 21 yr old mustang mare is arthritic in the spine. She is tender to the touch, and we even hated riding her, for fear we'd be putting her in more pain. Our trainer recommended Corta-Flx, and so we put it in her SmartPak. The results have been amazing. Our older mare is no longer sore to the touch, and runs around the turn out, bossing any other horse around like she's back on the wild ranges of Nevada. Her gaits are more fluid, and she seems so much younger! We know it's the supplement, because if we run out, she starts to seize up again. Thank you, SmartPak for including such a wonderful product in your service. Sincerely, Michelle in San Marcos, CA

    Rated 5 out of 5 by from It Really Works...Just Need Patience I used Corta-Flx on my 25yr old gelding who has a huge painful bone spavin from an old hock injury. I just wanted to get him to be as comfortable as possible. I had tried everything from acupuncture to injections with no changes. You have to feed it religiously for at least 2 mos. to show results. Eventually, he was back in the arena at our play days beating the youngsters & enjoying every minute of it. It really, really works. Just be patient.

    Rated 1 out of 5 by from Ineffective I used this product on a mare who was beginning to show signs of early arthritic changes. I did the loading dose, extended the loading dose period an extra week, and never got any response. I've heard others say it worked miracles for their horses, but it didn't on mine. Keep in mind that not all horses metabolize all medications the same. Keep trying different ones until you find one that works for your horse.
