    Absorbine Flex + Max is rated 4.6 out of 5 by 155.
    Rated 5 out of 5 by from works great for my horse I am feeding Flex max to a 10 year old Standardbred gelding, a retired racehorse. He has ringbone and arthritis. He frequently walks "sore" but wouldn't classify him as "lame". He is strictly a pasture horse, never worked anymore. Winter cold is terrible for him. Usually I just fed him this supplement in the colder months, but this year he is sore through spring and summer. Started him on it two weeks ago, and he is now showing signs of no stiffness and pain.I have used it many times for him in the past but took him off in summer. I plan to keep him on it year round. Wish it was cheaper to purchase, but it really works so I will continue to get it for him. Good product ingrediants cost more, plain and simple. I tried other brands from the big box farm stores, none of them made a difference at all, as FlexMax has much higher amounts of t he ingredients it needs to be effective. Smartpak is the cheapest place to get it, and the free shipping helps too. It is always on my doorstep in 2 or 3 days from when I order. Very, very, happy with this product's results. Love SmartPak as well.

    Rated 3 out of 5 by from don't know yet I'm giving this to a 14 year old mainly for maintaining his joints. I can't tell if it is making a difference, but I'll probably continue to give it to him.

    Rated 5 out of 5 by from THE most finicky eater EVER loves this !!! We just started this product yesterday and I'm only writing this to help others with extremely picky eaters. Our 10 yr old Belgian gelding LOVES IT!!! After trying numerous other products that he refused, we will anxiously await the outcome of this supplement. He has a bum stifle from a pasture injury. I will update his progress.

    Rated 4 out of 5 by from really works Seems like after a week or two my older gelding started using Absorbine Flex + Max, he was able to get up in the morning without being so stiff after an evening race. Really helped him out so I started giving it to my other 2 boys so they could repair joint and cartilage before they got broke down and stiff

    Rated 4 out of 5 by from Pickiest Horse on the Planet Approved I literally have the pickiest horse on the planet when it comes to food. This is a horse that will starve himself to death before he eats something he does not like. He refuses grain if it does not have molasses in it, he refuses hay if it is not the right texture, he refuses every supplement I try, even if it is mixed in with a senior feed he does like, he will not eat the supplement or the grain. When I saw this supplement I was wary of trying another, but with the satisfaction guarantee, I gave it a try. I was shocked to see him eat this from the very start. I did not have to start out with hiding just a few pellets in his grain. True to it's word, it is picky eater approved. Since I have only been feeding it a short while, I can not say quite yet if it has improved his joint issues or not. He has pretty severe arthritis in his hock as the result of a broken and repaired splint bone. He does appear to be running around more, and I have yet to see him canter 3 legged like he has done in the past. Yes, on three legs. I am hoping that this supplement is helping and I will for sure order another container.

    Rated 5 out of 5 by from Really works! There is a noticeable improvement in my wonderful 15 yr old Paint gelding. While always happy to go trail riding, he has more "go", definitely more forward and less stiff. He has been playing in the pasture with my younger QH - galloping and bucking! I am very happy with the results. He cleans it up and the SmartPak is a great convenience. Worth the money.

    Rated 5 out of 5 by from Amazing product!!! I have bee using this on my 12 year old cob who's joints would pop every step he took.  I felt so bad for him after 2 months of being on this he has completely stopped popping.  He will not go without it from now on.

    Rated 4 out of 5 by from most complete formula for cost Researched joint supplement ingredients some years ago. Flex+Max has almost everything I want at therapeutic levels. I sometimes add MSM because I've been told that 10 g. is necessary to make a difference. There are one or two other combination joint supplements that I might rather use, however, Flex+Max was the most economical. My mare is 19, moderately fit, never worked all that hard, and so far hasn't demonstrated any significant/consistent joint problems. She does have arthritis in one hock/ vet. Has had some chiropractic issues this year. My own orthopedist said that glucosamine and chondroitin supplements might be preventative. With my previous horse, he did feel better on a joint supplement as he aged and began to show discomfort. So, I'm hoping to prevent or at least slow down any more deterioration and control what she does experience from time to time.

    Rated 5 out of 5 by from Love at first bite! My two AQHA's are fussy supplement eaters and they loved this at first bite! They clean it all up!  No product waste.  Therefore, I saw results in two weeks. Joint stiffness gone completely in my mare and more flex to my gelding--ages 11 yrs old and 14 yrs old.  I will keep using this in their daily rations.  Flex-Max delivers!

    Rated 5 out of 5 by from Very Pleased My mare had spinal degeneration and was very uncomfortable in spite of bute, steroids, and generic glucosamine. I started her on the Absorbine Flex + Max to try out a different supplement approach. She responded well and we were ultimately able to stop the steroids. She spent her final year on the Flex + Max. She was also a fussy eater, so finding a supplement she would eat was a big bonus.

    Rated 5 out of 5 by from Joint comfort Epic is an 18yr old Oldenburg mare used for dressage. She also is a proven broodmare having 6 foals of which 2 are premiums during inspection. I feel dressage can be hard on a horse because they must work off of their hindquarters. I take glucosamine myself - I am definitely older than 18 - and I believe it helps me. So why not try it for your horse too?

    Rated 5 out of 5 by from Really helped My mothers horse has pretty bad arthritis so we put him on these (reccomended by our farrier) and it really does help him! He has a lot more get up and go on these supplements. The horse eats them like candy!

    Rated 5 out of 5 by from Great Product that Works! This product is great. I have 6 horses in my barn on it and they are all doing great! The older horses feel better, the competition horses dont come out of their stalls stiff and the results are very noticeable. I would highly recommend it to anyone. I have all ages, breeds and picky eaters on this. They even eat it without grain. The price is great too considering the amount of HA in the product.

    Rated 5 out of 5 by from A good supplement I have fed 4 full buckets of this to my Mini who is foundered on all 4 feet. She has a correct trim, sole support, and a proper low sugar diet, she's in good weight, and lives on soft, supportive footing, but she is still extremely lame on all 4 feet and lays down most of the time. I started her on this as a last ditch effort to keep from putting her down. With this supplement, she could get by with about 1 gram of bute per day, and while still sore, she would walk around outside with the others, and even trot a few steps on good days. I ran out and did not buy any more because I didn't realize it was working that much. Within about a week, she had hot, pounding pulses in all four feet, and was again miserably lame and laying down all the time. She was back up to 2 grams of bute and still wouldn't move much. I put her on Rapid Flex fast acting joint supplement - double dose - because it has devil's claw and yucca in it. That seems to help her a lot also. So I don't think it has to be THIS joint supplement, but she just needs something. I would not hesitate to buy this again, and would if it had Yucca and Devil's Claw for added pain relief. My hope is to stop the bute completely and I couldn't do that with this supplement. I hope I can with the other supplement. Overall this is a GREAT product and did improve my foundered Mini significantly!

    Rated 5 out of 5 by from Absorbine Flex+Max I have an 8 year old Mustang that has had alot of issues getting a correct barefoot trim. He has developed arthritis in one knee. I have a 19 year old quarter horse mare with navicular. I started feeding the Mustang one month ago and have noticed improvement in his stride and his turning. I decided to try the mare on Absorbine Flex also. It has been two weeks now and I am noticing marked improvement.

    Rated 4 out of 5 by from Good Product This product has really been good for my senior horse. Have used a number of other products for joints and this one is doing the job! It is also easy to use and no issue with being consumed as it is pelleted and goes in with the feed - with no residue at all.

    Rated 5 out of 5 by from Great Joint Supplement! My mare is only 13 y/o, but I decided it couldn't hurt to put her on a joint supplement. I chose this one base on the ingredents. And I must say, I feel the improvement. She feels great! I am truley surprised at how much it has helped her. It's worth the money.

    Rated 4 out of 5 by from Good First Time The first pack I got was amazing. It smelled delicious and my horse loved it. The second I got wasn't so great. It had this really weird smell. Not sure why. My horse still ate it, it just left me a little wary. Not entirely sure how it's doing for him with soreness. We discovered that he has a bone chip which is causing the soreness in the front end. The supplement seems to help keep the rest of his legs compensate for it, but it's still a crazy mess.

    Rated 5 out of 5 by from Great suppliment We use to use the Cosequin ASU which I love but is SO expensive! This supplement seems to provide the same results at a fraction of the cost. All my competition horses are on it. My 14 year old thoroughbred Rhett has been competing in the 3'3" Performance Working Hunter division and is on this supplement. He is moving and jumping great since starting it. He has been on it for about a year and half now and we were able to go over a year before having to do hock injections thanks to this supplement.

    Rated 5 out of 5 by from Great ingredients for the price I was using a more expensive product and getting great results, but I have 3 horese on joint supplements and had to reduce cost. I found this product and switched one horse at a time. Still getting great results at half the cost. Results I value are less tripping on the trail, less joint stiffness, better fluid movement, hind legs reaching under and extending, loser hock movement and willingness to jump.

    Rated 5 out of 5 by from Love this Product I have my 25 year old QH horse on this product and I love it. He has been on quite a few different joint support supplements over the past few years, but he will continue to be on this forever unless there is a huge price increase :) Definitely the most bang for your buck with this product.
