Rated 4.9 out of 5 by 15 reviewers.
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
Rated 5 out of 5 by this product is wonderful i really like this product i love how it makes my horse feel as i run barrels on her and it really does work!! she runs and turns so much better while using rapid flex!! May 9, 2010
Rated 5 out of 5 by Wonderful results I saw a friend use this for their horse that was in his mid 20's and would lay around and not want to get up. Within a week the horse was up and running around. I use it on a 20yr old and 17 yr old with great results. They act as if they are 10yrs younger. You can see they their joints and body motion feel so much better. (This does not hypp up a horse if you are asking.) March 20, 2010
Rated 5 out of 5 by Very good! i adopted a 24 year old arabian gelding with very bad arthrithis.. he would not eat the medication what the vet gave us, so i bought rapid-flex wich worked from the first week!and my horse has no problem with the taste. November 10, 2009
Rated 5 out of 5 by miracle product rapid flex is wonderful. i had a horse with severe arthritis. she could barely walk when i got her. my vet wanted to put her down she was so bad. after 2 weeks, she was up walking. after a month she was doing even better. 3 months my vet came back and couldnt believe she was up walking and even trotting to her feed bowl. he now recommends rapid flex to all his clients. this is a great product and i tell ever one to use it.

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.

How does this compare to devils claw plus or easy willow?

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.
