    Corta-Flx is rated 4.5 out of 5 by 68.
    Rated 5 out of 5 by from Simply the best. I've used this product off and on for over 20 years with great results. Currently, I have a mare who has advanced ringbone and this product has helped her regain mobility and comfort so that she may be exercised lightly and continue with un-mounted work in our equine-assisted Psychotherapy program.

    Rated 5 out of 5 by from Used for ringbone I started my draftXqh mare on this a month ago to improve movement. She has almost fused ringbone and I haven't had to give her any bute in three days! (She was on 2 scps/day with 12hr t/o) I started the other four horses on it as well I'm so impressed!

    Rated 3 out of 5 by from I used this and Bute at same time and they helped I used this for two months along with Bute and the combination seems to help. I only gave 3 stars because I'm not sure if it was the Bute or the Corta-flex or if it was the combination that helped.

    Rated 4 out of 5 by from It works! Have tried other products for 23 yr old with some success but this seems to have had a faster and more noticeable effect. She's less stiff and sound in front again. still some creaky hocks but she had a hard life prior to coming to us at age 12.

    Rated 3 out of 5 by from Cotta Flex I bought this in June per my vet.  My horse is 26 and has soreness and joint issues.  I have since retired him and put him on Corta Flex.  It has seemingly improved his movement and comfort.  But I'm starting to think my horse is no longer responding to this product, we may switch to something else.  I have found this situation to be true in two other horses- a friends horse and one of my others.  All in all I thinks it's a good product but you may need to switch to something else every so often...

    Rated 5 out of 5 by from Locking stifle solution. I have an 8 year old Haflinger gelding who has weak stifles and after having been on stall rest after an extended illness, his stifles started locking on him. After reading the reviews for this product, I thought I would give it a try. I started seeing results after 2 weeks and even though he is still on light duty, I haven't seen the stifles lock once. My barn owner is very impressed with the results she has seen as well. Will definitely be adding this supplement to his feed on a regular basis. Dry or liquid form, he cleans up every last bit. Glad I found this.

    Rated 5 out of 5 by from Great Product Have noticed a difference in my horse since starting him on corta-Flx pellets. He can be a picky eater, but he never leaves this in his feed tub. Love Smart Paks for their convenience, too!

    Rated 4 out of 5 by from Best Value Like other reviewers, I was also hesitant to try different supplements due to financial reasons. I had used Corta-flx with great results years ago before there were a million other supplements to choose from, as it was vet recommended. Like other reviewers I figured it was outdated compared to newer items on the market, but I could afford it so gave it a try. I am so glad I did. I foxhunt, hunter-pace and trailride my mares. Not only is my mare that was stiff feeling unbelievably more comfortable with improved gaits and improved attitude - but also their coats are really glowing more than when they were just on their Purina feed alone.

    Rated 5 out of 5 by from I keep coming back to this one I started using this product over 10 years ago when it first came out. I have tried other products, and I keep coming back to this one. It works. I do have to discontiue it a week or so before endurance rides because it contains MSM (a big no-no for endurance competitions) but that is easy to do because I can just cut the Smart Pak well off and save it to double up after the ride.

    Rated 5 out of 5 by from all-around standby Corta-Flx is a good buy suitable for horses young and old. I supplement with Focus SR for my 24-yerar-old thoroughbred, and it is a good combination that I feel works better than the Corta-Flx Senior supplement.
    Date published: 2011-08-30
    Rated 5 out of 5 by from Keeps them going! I use this on 2 horses. One older stiff mare and a huge thoroughbred as a preventative. It works wonders on the older mare! It also worked very quickly , i saw results within the first week on the loading dose. She now moves with ease. Seems to be keeping the big guys joints happy and moving free.

    Rated 5 out of 5 by from Works like a charm My Clyde gelding was on a flex supplement when I bought him this spring. The first time the farrier was out he could barely hold up his hind legs for the farrier and we had to lower the hoof stand and give him breaks. I was hesitant to try different supps for financial reasons, but had used Corta Flx on an old mare of mine that I had 12 years ago. I had figured that if his current supplement didn't work with all of the new technology available then Corta Flx must be outdated and probably wouldn't be any better than what he was on. Not to mention it is one of the cheaper supplements on the market. I was wrong!! The next time the farrier was out my gelding stood very comfortably for his hind feet to be trimmed! I will always use Corta Flx!!

    Rated 5 out of 5 by from Can't move without it! Put both my horses on this and noticed a BIG difference in their movement. Both where not stiff anymore. One of my boys is 19 and the other is 25. Both started to move amazingly. I tried switching to a cheaper supplement to save money and they became stiff again. My 25 year old wouldn't run in the pasture anymore. Never again will i take my horses off of CortaFlex. Nothing will compare!

    Rated 4 out of 5 by from Picky Horse Loves It! My horse can be a little picky when it comes to supplements. I have the liquid form of CortaFlx because I was told that it is absorbed better.....(questionable...). But with CortaFlx, she will eat it, even without grain (it even smells yummy). I am not sure if it is actually doing anything, because I am using it mostly as a maintenance because my horse is only 5, however she has a small amount of arthritis in her hocks. We keep her on Adequan as well. I am thinking about trying the pellets next time because the liquid is messy.
