FLEX-N-ACTION is rated 4.5 out of 5 by 109.
Rated 4 out of 5 by from Seeing improvements My guy with bad knees has improvement with this supplement. It won't be 100% but he definitely is more comfortable.

Rated 5 out of 5 by from Affordable! This product had great levels of everything you want in a joint supplement. And it wasn't expensive. I think many other brands charge just for the name!!

Rated 5 out of 5 by from Great product The pellets have made my 17 year old thin thoroughbred happier than ever. The pellets have helped comfort his joints through our dressage and jumping lessons throughout the week!

Rated 5 out of 5 by from Great product I can see an immediate improvement in my gelding who required a lot of time off. He still looks muscled up and ready to work.
Date published: 2016-04-27
Rated 5 out of 5 by from Great benefits! I bought this supplement about a month ago, my horse is a pretty easy keeper and this supplement helps keep her an easy keeper by hitting all the key points I like in a supplement.

Rated 5 out of 5 by from Good Quality Supplement I switched my 11 year old Thoroughbred gelding from the basic Fluid Action joint supplement powder about a month and a half-two months ago. He wasn't eating the Fluid Action, but from the beginning he has been happily finishing all of the Flex-n-Action pellets! I like that this supplement has a great price, and offers a lot of important ingredients in levels recommended by my vet. He seems quite happy on it, and the cracking in his joints I heard while he was on the prior supplement has gone away. So far so good, he and I are quite happy!

Rated 4 out of 5 by from Love the big pellets, easy to feed! I bought this for my gelding who was having swelling in his hock, I believe it to be wind puff(will have ex rays done this spring). I haven't seen and improvement in his hock yet but love the long pellets, easy to feed. You can feed the pellets out of your hand or mix with grain. My gelding ate them from day one! I'm still feeding from the container(: only gave 4 star since I haven't physically seen improvement on his hock.
Date published: 2015-01-07
Rated 4 out of 5 by from So far so good! Purchased this for my older gelding who has become a picky eater and has some seasonal stiffness & mobility limitations. Have had no problems with him eating it on his grain. So far he's moving better but it hasn't been that cold yet! I'll give a 5-star in the spring if he's still this sound after the winter!!
Date published: 2014-12-19
Rated 4 out of 5 by from Great Value for the price I got this for my 10yo gelding. We do a lot of stuff in the summer including lower level jumping and endurance rides, so I wanted to get it as a preventative. I haven't noticed any changes yet, but I only started it a month ago, and he didn't have any major problems to begin with. That said he hasn't come out stiff at all in the month I've had him on it. I will be trying Smartcombo pellets, because with winter coming I'd like to have some extra supplements in there, and after doing some research, I think the joint supplement in the smart combo just provides a bit more.

Date published: 2014-05-26
Rated 5 out of 5 by from joint supplement I recently decided on this product by doing heavy research into the joint supplements for horses. I wanted Glucosamine HCl, Hyaluronic Acid, Chondroitin Sulfate and MSM all in one supplement. The amounts are just about as good as it gets, yet I do still give one scoop of pure MSM in addition. There isn't any "forbidden" herbs in here and I know it helps a lot in my OTTB's. I bought this one in the bucket which is hard to open, reseal, and open again, but only one "medicine cup size scoop" (included) once a day, not overly pricey and best yet-pellets!! I'm sold! :)
Date published: 2014-04-03
Rated 4 out of 5 by from Good value I recently switched over from the Flex-N-Motion because it really wasn't providing enough collagen/gelatin for tendon/ligament support, plus this one is a bit cheaper.  I like that this one includes MSM, but it's a bit on the low end of the range.  I had some leftover MSM from when I was feeding the Flex-N-Action, so I'm adding just a small scoop to get up to the suggested range for my mare's weight.  Otherwise, I think this supplement is a great value, it provides the Glucosamine, HA, and Condroitin Sulfate in all the recommended amounts.  Just wish it came in bigger's a pain to order one every month, but I guess that keeps it fresher!

Rated 5 out of 5 by from great value This is the best product as far as active ingredients /dollar. It has everything I was looking for and not the products I didn't need. I also like that it is a pelleted supplement - doesn't get left in the bucket.
Date published: 2013-12-31
Rated 5 out of 5 by from great product started using this product on my daughters 11 yr. old Appendix Quarter horse. It definitely works he is not as stiff as he use to be and seems to be much happier.
Date published: 2013-05-09
Rated 5 out of 5 by from Feel-Good Supplement This supplement met all of my big guy's joint needs at a reasonable cost. He hasn't had any major joint issues, but (just in case) for his comfort, and my peace of mind, this supplement has him covered!
Date published: 2013-04-15
Rated 4 out of 5 by from love it! I really love this product. All the ingredients of a much more expensive product in a very reasonable package. My picky mare eats it right up. And you can't beat the cost! Her joints still crack some, but I haven't found anything else comparable to the price/ingredients.
Date published: 2013-02-07
Rated 5 out of 5 by from Great for joints I have a 12 y/o TB mare who was jumped extensively in her younger years. I started working her and she was not moving as well at the end of our rides. I put her on this product and she moves well throughout the whole session. I used smartpak's compartive rater with regards to other joint products and this had everything I was looking for along with a great price. I would definitely recommend this for joints!

Rated 4 out of 5 by from Helped out my old timer big time Seems to be working very well on my older horse. For the price you can't beat it.

Rated 5 out of 5 by from Good supplement Using this for preventative maintenance. See no difference between this supplement and the more expensive brands. She eats it well and none is left behind.

Rated 5 out of 5 by from Good Value My 6-year-old OTTB moves better than ever, strong and sure. Great value!
Date published: 2012-05-03
Rated 4 out of 5 by from Not entirely sure whether it worked or... I just started my horse on this product a month ago in hopes of helping her be more comfortable in her stifles and hocks. She was on SmartPak Maintenance, and I felt for her workload she needed a step up, but without the huge step up in price. This product has great ingredients, and my horse felt really good yesterday, however, she did just get her first round of Adequan and Legend. Those injections may have something to do with how she felt, however, generally they take awhile to work. So, I am cautiously supporting this product. Will have to wait and see...

Rated 4 out of 5 by from Flex-n-action this is good but too much MSM for a horse with ulcers so went to the Flex-n-motion it has no MSM and if ok for horse with ulcers and winter arthritis last winter, so only fed the msm only for short time and went back to no MSM Thanks for all your support on the help line.. the difference is incredible for her when she is not on MSM but it does help her arthritis stiffness in winter, just don't like feeding it too long or etc. Thanks for your help

Rated 5 out of 5 by from love Love LOVE this product!!! My Greyson is a FORMER auction Killpen horse. He came to me unsound. At first I thought it was because of never really having his feet done. After about 8 months I found an AWESOME farrier. His feet are not the problem. Long story short, I figured I would try this. All I can say is W-O-W!! For him to go to a STRONG head bobbing lame, short choppy steps, can barely pivot to No head bobbing and 95% sound. Im happy he is comfortable. That's all I ever wanted for him.

Rated 5 out of 5 by from Best buy The joint supplement chart is the best way to review all supplements. We have tried a few brands but have kept with Flex n Action for the % breakdown of each ingredient. Our 13 yr TB, sound three years since knee surgery loves it.
Date published: 2012-01-20
Rated 5 out of 5 by from Huge improvement Did not expect a big change in my gelding but saw a huge improvement in his attitude towards learning new and difficult things. Warm up is a lot easier for him now too. He is a little picky with supplements in powder form so these are perfect since they are pellets. He also loves them as treats :)
Date published: 2011-09-22
Rated 5 out of 5 by from Really helped my daughters horse Tory is 20 years old and has been the love of my daughters life for over 15 years. When he started to have knee issues she was very concerned. Talked to our vet and the recommendation was to try Flex -n- Action. After just 6 days on the dose knee swelling was greatly reduced and he is feeling better in work outs and wanting to go hunting again. Helped us get get back in saddle and enjoy horse ownership.

Rated 4 out of 5 by from Good Product & Price! This is a repeat purchase. Has the ingrediants I want & a price I like. My horse eats the pellets - no powder left in the bottom of buckets. Easy to measure out, I feed at night in the dark! 25 year old Zia moves so much easier when we are competing in the CTC rides - that's why she is a repeat champion!! Thanks SmartPaks.

Rated 5 out of 5 by from great value was surprised. this product worked very fast and I saw results in just little over a week.
Date published: 2011-06-06
Rated 2 out of 5 by from No. My horse would eat these straight from my hands, but then again, he'd eat the kitchen sink if I offered it to him. He was on these for almost six months and I noticed absolutely no difference. Changed to straight MSM (along with a few other extras) and he's acting like a five year old again. Would not recommend this product.
