CORTA-FLX® is the first of its' class to feature pure, micro-sized, water soluble, isolated nutrients comparable to the active ingredients found in Chondroitin, Glucosamine, MSM, and Hyaluronic Acid.

CORTA-FLX®'s smaller molecules mean higher levels of absorption and enhanced consumption. Made from fortifying ingredients, FLEX-FORCE® Pellets with HA have been specially formulated to improve joint function in horses of all classes.

Rated 5 out of 5 by 5 reviewers.
Rated 5 out of 5 by Love IT! After giving weekly shots of glucosomine, my mare was still stiff on cold days. I wanted something cheap that worked well to add on top. This was it! After only a month she is running around like a 5 year old, bucking and just having a great time! I decided on this after looking into devils claw and straight msm, but decided on this. I like that there is not a large amount of msm in this, as I was told it was bad to feed long term. January 14, 2013
Rated 5 out of 5 by Nice Product, Great Price Have an older mare that was getting stiff enough that we were having trouble even trimming her. Took some hunting around to find something that worked and was affordable, this product did it for us. The trimmer even noticed that she could stand easily for him, and she moves much more freely than in past months. I was surprised how quickly it made a difference. January 28, 2012
Rated 5 out of 5 by Exceeds expectations! I was at my minds' end trying to find a supplmt that would REALLY work for my 25 and 31yro horses. This really came thru for me! Horses are more "fluid moving" and cantering freely again! December 19, 2011
Rated 5 out of 5 by Fantastic Product I use it on both my mares, one just for general purpose and the other cause she is older and needs it. It does a great job and keeps them both pain free and their joints working good. The price is affordable on a tight budjet. It really does work and the horses love the taste, I give it to them with a little grain. September 2, 2011
Rated 5 out of 5 by Great product! It was really nice to see a quality product for a more than reasonable price on the market. I was skeptical at first because of the price but i was willing to try it, and i was way worth it. One of my horses is getting a little older and is ridden alot, all year and has mild arthritic symptoms especially in winter, this product worked great for him! Hes able to move out much better extending his trot and collecting better. So happy to see him more comfortable. So worth it to try. :o) January 11, 2011

Why did you choose this? Store
I have a 20 year old horse, want to keep him sound and happy for as long as I can. This product had all of the major joint supplements I wanted, for a very good price, matched with the amount of servings you get, for that price.

Seems to work a little better than just Glucosamine. There are more supplemental items in this product.

So I ordered a 4lb container that says it has 128 day supply. But it ran out in about half the time it should have lasted. Has anyone actually measured how many scoops are in it?
Tobin R on May 1, 2014
Best Answer: Hi, I buy the flex force pellets also. The maintenance dose is 1/2 of a scoop. If you use the maintenance dose I find it usually lasts the 128 days as stated. When it comes I put a smaller scoop in the container that way I feed a full scoop and there's no measuring.

Really trying to decide in Flex force and corta flx??
A shopper on Mar 16, 2014
Best Answer: This is probably the best supplement for the price. I use the flex force pellets as my base and also purchase msm and glucosamine powder so I know my horse is getting the right levels of each. I also combine this with a vitamin. With all of that I still pay less than purchasing a product that has more glucosamine/ msm already in the pellets. I've had my horse on this product since she was 4 and she will be turning 7 this spring and haven't had one lameness issue with her. It's a great product I'm glad I ran across it!!
