Rated 5 out of 5 by from Best Joint Supplement! Keeps my 12 year old quarter horse feeling like she's 5. Have never had a problem lameness or joint wise with my mare yet. She's feeling good and cruising around eventing and jumpers without a problem. She gobbles this right up!

Rated 5 out of 5 by from noticed improvement in 1 week! Horses eat the pelleted supplement without hesitation so you know they are getting the product! In the first week of feeding this supplement, our 5 year old warmblood cross had more reach in his stride and felt more comfortable in transitions. We have kept him on it for nearly a year to maintain his joint health during workload increase.

Rated 3 out of 5 by from My guy wasn't a fan. Super-picky gelding owner here. I loved the ingredients, but he didn't love the taste. I offered them in a feed bowl alone and there was absolutely no interest. Mixed in with his other supplements, grain, and hay stretcher, and who knows how many ended up in the substantial dust left in bottom of the food bin by morning. I was never quite sure how much he actually ate. Too expensive to not know they were getting eaten, so I'm moving on.

Rated 5 out of 5 by from Extremely palatable I've had trouble finding joint supplements that my horses will eat because they are very picky eaters but there has never been any rejection of this one.

Rated 5 out of 5 by from This is a Must Have!! I rescued my 2002 Swedish Warmblood back in 2011 and he was run into the ground at an early age and developed arthritis throughout his neck, ringbone, sidebone, and overall extremely stiff. The first vet that I had see him told me he was a lost cause and to put him down but I never gave up on him. Today I have a 100% sound horse and although he was cleared to jump up to 3' I feel like it's in his overall best interest to stick to flat work to keep him as comfortable as possible. Also his injections have lasted 3 years & counting!! I'm confident with a combination of this product, additional MSM, his previcox, and back on track products he will continue to stay sound and comfortable for another 15-20 years!! This is the only supplement I know for sure ALL of my future horses will for sure be given! Thanks SmartPak and Absorbine for providing my best friend the best supplements, we are forever customers!!

Rated 3 out of 5 by from I have used this product on and off throughout the years. I think the content of ingredients are worth using and beneficial. Overall, I think the product is worth using and priced comparably to others in its class.
Date published: 2016-12-14
Rated 5 out of 5 by from I bought this product about a month ago and since then my gelding has seemed to be more playful. At feeding time he is bucking and playing. Before I started this product I could hear him comingo because he was creaking and craking. It seems like the cracking ha's stopped and he is more comfortable.
Date published: 2016-12-08
Rated 5 out of 5 by from Excellent product! I have bought this product and love that it has Hyuralonic Acid in conjunction with the other joint products. It is a complete joint product.

Rated 5 out of 5 by from Helps hooves heal and strengthen I have a couple issues with my horse this summer, however I do feel that Absorbine Flex + is helping maintenance of hoof health so that I can focus on his joints with my vet and trainer
Date published: 2016-09-22
Rated 5 out of 5 by from Anyone can feed to their horse Have used this supplement for 3 months on my 20 yr old QH. She was showing signs of stiffness in the back legs. So I noticed she is better already ,she loves the taste and I like the price. So I'll keep her on this.

Rated 5 out of 5 by from Good results after three months I switched from smartcombo senior to this, plus omega horseshine. My senior warmblood was starting to get creaky and sore so I thought I'd change it up. I love SmartPak's comparison charts, because they support my obsessive comparison shopping. This product had the best combination of ingredients I wanted at the best price. I saw Absorbine as a sort of Walmart brand, but I decided to give it a try. There's no really scientific basis for attributing it to this supplement, but my old boy is eager to move now and is not slightly off anymore after three months on this combination and no other major changes. I've had great results with joint supplements in combination with omega supplements in the past. My horse is a Hoover so I can't comment on palatability-- he will eat it out of my hand and act like its a special treat, for what that's worth!

Rated 5 out of 5 by from Absorbine Flex + Max I was using the Equine Senior and switched to this. I do believe there is a difference and this is definitely better for my horse.
Date published: 2016-03-31
Rated 1 out of 5 by from Disappointed I had spoken to a rep from Absorbine about this product and was willing to give it a shot to save a few bucks every month (I had my horse on SmartFlex III Resilience at the time.) I ended up being very disappointed with this product. It has more of each ingredient in it (than SmartFlex), but somehow just doesn't work as well for my horse. He's stiffer, his one hind leg gets very stocked up, and his legs "click" more. I'm guessing for a horse that has never been on anything and gets put on this, it would be fine. But I'm switching back to SmartFlex.

Rated 5 out of 5 by from Really works I tried this product first when I had a draft horse whose arthritis made it difficult for him to get up off the ground. As long as he was taking this supplement, we did not have to help him up. I really believe in this product
Date published: 2015-09-13
Rated 5 out of 5 by from VERY Palatable and EXCELLENT results!! This is a high quality product par for the course for Absorbine; good science behind this product! My 14 year old mare is the most pickiest horse ever and she loves this product, I give it to my arthritic dog as well (per directions on the label); both have improved dramatically!

Rated 5 out of 5 by from great My horse is happy with this! He looks great! I would recommend this
Date published: 2015-07-06
Rated 5 out of 5 by from Helps a "sound" horse I originally used this product when I was given a bucket to try by a representative of the company. My horse has no soundness issues but the product did seem to help her feel more comfortable in her right lead canter. Recently I noticed that she was gumpy about the right lead again. Again she is totally sound and when I mentioned that she was not on any joint supplements one vet said why feed it if she doesn't need them. But in the back of my head I remembered that the trial bucket did seen to make her feel better. So I added it to my smartpak and am pleased with the results! She seems happier again!

Rated 5 out of 5 by from My picky eater loves the taste. Chief has been using Flex-Max for two years now. He is an 17 year old OTTB, with an old suspensory ligament injury. We just competed in a dressage show and received two blue ribbons. I am convinced that Flex-Max helps my guy feel and perform his best.
Date published: 2015-05-29
Rated 4 out of 5 by from Flex Max is palatable I am pleased with the product and will very likely order more as needed.
Date published: 2015-02-24
Rated 4 out of 5 by from works great This is a great product, I have an older horse now in his twenties and this keeps him jumping and I really makes a difference. I have used a lot of other joint supplements and I think that this has worked the best. The pellets are great because they are eaten right up. Overall I highly recommend this product.
Date published: 2015-02-24
Rated 5 out of 5 by from works well for my 19 year old TWH I had my horse on other joint products this Absorbine flex +Max worked the best for him. He is less stiff in the morning when he comes out of his stall and he is moving with greater mobility! Great Product
Date published: 2015-02-10
Rated 4 out of 5 by from Lots for a relatively low price I chose this as a "broad spectrum" supplement for a 15 year old mare. She likes it, gobbles it right up in her grain, and I think she starts out more easily and warms up faster since putting her on it 4 months ago.
Date published: 2015-01-21
Rated 5 out of 5 by from Great product and my picky Mare likes it ! Really great product for my 16 yr old Hanoverian mare. She is picky and eats this right up. I can tell and also my Farrier can tell when I started her on this months ago, that she easier to work on her feet, and her right back hock is not nearly as sore as it was previously.. she moves like she is 6 years old!

Rated 5 out of 5 by from Our pony doesn't have to act her age Our old pony is as active and moves as well as when we first got her over 12 years ago.
Date published: 2015-01-09
Rated 5 out of 5 by from it works! My OTTB has been on this for 3 months and has never felt better!
Date published: 2015-01-08
Rated 5 out of 5 by from Great supplement, and great price! This has been working well for my mare. Of the top ingredients that my vet wanted her to have in a supplement, in high amounts, this hits the nail on the head without breaking the bank. Other comparable supplements are way way way more expensive for not much difference in formula! As for taste, my mare will eat almost anything I put in front of her, so it's hard to say about picky eaters. Sometimes after a hard workout I give her extra, and I give it by itself with no grain and she eats it just like grain though.
Date published: 2014-12-12
Rated 3 out of 5 by from Good product Good product & my horse likes it. The bucket I got said it should last 60 days and it only lasted 30 though.
Date published: 2014-11-26
Rated 5 out of 5 by from finally! Bought this over a month ago and I've seen a huge improvement in my OTTB's flexibility and soundness!
