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.

This product is awesome. My 18 year old Paint mare has improved in 3 weeks. She is very arthritic in her knees and seems to be not as stiff improving her mobility.

I have aging horses and this product seems to help them move around well. They don't seem to be as stiff in the joints.

This stuff works! Amazing recovery for my arthritic horse...more movement with obvious less pain. Works fast too

any side effects, like hyper active ?
A shopper on Sep 5, 2014
Best Answer: I have used it on both of my TB horses without finding that to be the case. One is very easily influenced by feed/supplements and gets lots of energy easily, not the case here. Both seemed to benefit from it. One is still in work and the other is retired. Seemed to work on the old joints as well as the one recovering from an injury. I would recommend the product because of the added benefits that the yucca, devils claw etc give!

What would the dosage be for a pony approximately 800 lbs?
Elizabeth H on Nov 3, 2014
Best Answer: That's a great question and I'm glad you sought some guidance before starting the product. I have been using Rapid Flex for a few years for an 18 year old gelding with arthritis in his knees. He is approximately an 1100 pounds Quarter horse. The full serving cup size is for an average size horse (according to them that is 1200 pounds). Therefore, I would feed an 800 pound pony 2/3 of the cup provided. Good luck and I hope your pony gets the relief it needs!
