Rated 4.9 out of 5 by 12 reviewers.
Rated 5 out of 5 by Excellent Stuff! I have tried many joint supplements and this one works the best. Horse has no issue with the taste of it. It truly helps relieve arthritic joint pain! November 16, 2012
Rated 4 out of 5 by Great supplement Love it. Unfortunately, it is sold at walmart for $5 less than state line... July 31, 2012
Rated 5 out of 5 by Wonderful Product I tried different joint supplements for our 12 year old rescue who had suffered shoulder and leg injuries from an abuser. This product has him walking near normal and keeps him comfortable. He acts like a horse now! It's a staple in his diet. May 29, 2012
Rated 5 out of 5 by Love it! My 26 year old QH mare has had broken splint bones, bowed tendon, and a cracked sesemoid in her long career. Rapid Flex keeps her moving like she was 15 years younger. Easy to feed and always cleaned up from the grain dish. "Beaner" gives it a 4 hooves up. May 11, 2012
Rated 5 out of 5 by Works fast, makes all the difference I have a 9 year old eventer who has gotten a little sore in her hocks. I have had her injected but it's very expensive. When her injections ran out last year I decided to try a supplement before I had her injected again. Rapid Flex makes all the difference in her performance. Plus, with the natural pain relievers, she seems to be less stiff after a hard workout. I would recommend this product to anyone with a performance horse or an older horse that is a little stiff.

Rated 5 out of 5 by reordering I never write a review for anything I buy online. I have got to tell anyone looking at this product. BUY IT NOW! I have an aged Percheron mare which I adopted from a rescue. I have had her for a year. Recently she had a tendon issue which is healed and had a Very tough way of going. I knew when I adopted her she had some arthritis but it was not an issue until the tendon swelling. My horse was lame all over. Her back all of her legs it just broke my heart. The vet said I should consider putting her on a supplement for her joints and arthritis. I ordered Rapid Flex. It appeared to be affordable and contained yucca which was very important to me. This stuff is amazing! within 3 days the improvement was huge. Nothing works in 3 days right well this stuff does. My horse loves this stuff. Licks the bottom of her feed pan to get every single crumb. If your horse is stiff and can not get around you need to try this. Being a draft, my horse has worked very hard in her past, she was used to pull and drive. She had a very hard life before. If you love your old horse like I love my old horse and age has not been kind. Do try this product it is amazing. September 16, 2011
Rated 5 out of 5 by Awesome Product.. I have a 9 year old quarter horse and he absolutly loves this product. He has shown so much imporvemnt in how well he moves his body for me and he is even more willing to work for me. I dont notice him stiff anymore either, only happy. This product is for sure woth every cent! December 14, 2010
Rated 5 out of 5 by Amazing!! This stuff is AMAZING! I have a 4 year old OTTB that came off the track with an Osselet, I put him on this stuff after checking out reviews on-line about 2-3 weeks into his injury (i purchased him a week after his last race when he acquired the osselet.) It didnt really make a difference right away or anything but i can DEFINITELY see the difference now, 6 months later. He lost a minor amount of flexibility as is expected with osslets but it really did help with how much he still has left compared to what it would have been without. He's not taken a bad step since i put him on it, He used to limp before when being walked at a walk/trot now he shows no signs of discomfort. I really love this product if not for it i dont think my horse would have had a potential career in hunter/jumpers. He starts retraining in a few weeks :] Thank you Rapid-Flex! October 25, 2010
