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.

Gelding is a little stiff, I usually use SmartFlex but this is on sale so I'll try it.

Best joint supplement on the market. We have a 22yr old Quarter Horse who had joint issues and was sore for him to move around. Now he is in Western and English horse shows almost every weekend and if not showing is out pleasure riding 6-10 miles per day and most of it in a trot or canter. Love this stuff.

Best Answer: The Rapid Flex is a blend of a variety of natural herbs used for inflammation which is the cause of pain. Devils Claw is a single ingredient and may not be enough depending on the horse's issue. Easy Willow is the base ingredient of aspirin and should not be used long term due to effects on the overall health as well as stomach issues. Longer than 2 or 3 weeks is long term. It can be more effective in the short term. I have used Rapid Flex and Easy Willow with good results but for different purposes. I now supplement daily with tumeric (non-irradiated) for overall inflammation since the main purpose has resolved/healed.
