Have used this for years. Vet says it's good stuff. Used it on one horse until he died at 30. My 20 year old has been on it for 4 years and my show horse is also on it.

I bought this for my barrel mare to help keep joints healthy and pain-free.

Horse needs it to help joints.
Deborah G on Jun 24, 2017
My older newly gelded fella has some big back hock joints....not sure if it's old injury or from breeding mares. He sometimes seems stiff and sore after the farrier comes and he has to bend those joints. I am hoping this offers him some relief!
Holly M on Jun 21, 2017
Best ingredients of any other joint supplement. Has worked for my Senior horse for 3 yrs now.
LORI P on May 30, 2017
this definitely works to provide relief for my 32 year old who has arthritis in his hip.
Larry G on Apr 5, 2017
It's a good value.
Ann B on Dec 29, 2016
i have a senior horse that is stiff after riding, hope to alleviate some of that and make him more comfortable
JEFFREY H on Nov 4, 2016
Has all 4 major joint ingredients
STEPHANIE M on Jun 8, 2016
I have a 22 year old horse who basically has degenerative joint disease in her hock. When she's on this she seems to do better, her hock doesn't bother her as much. When she goes off of it, her hock seems to bother her more. I tried another brand before this and saw no difference. I'm sceptical of "herbal" medications, but this one does seem to be genuine, at least for my horse. Not saying it would work for someone elses as all animals react different to different things. I would recommend.
Leslie H on Nov 30, 2015
My horse has stiffness on the front shoulders. This is the only joint supplement that I have found that helps him.
CINDY H on Nov 29, 2015
My mustang (unknown age) has been moving slower and slower. want to helkp him through the winter.
LINDA M on Nov 15, 2015
Works great
CINDY B on Oct 14, 2015
has all the things my vet recommended and great price.
LAUREN R on Aug 28, 2015
Because Absorbine products are ones you can count on. The ingredients offered good levels of the supplements I'm looking for and adding fenugreek to the pellets makes them quite palatable. My horse really likes this joint supplement and it has helped his overall movement since he's been getting it every day. He's 29 and is slightly arthritic.
SUSAN T on Aug 14, 2015
Easy to feed and really works as joint supplement for my aging games ponies. Made them more comfortable and happier during performance.
Jennifer C on Jul 31, 2015
It has worked wonders on the joints of our 24 year old horse. He has improved a great deal.
Patricia G on Jul 28, 2015
Have been buying this for a number of years in the hopes that it helps to keep my horses from having joint problems-prevention better than a cure. Have not had lameness or stiffness although I can't say absolutely that this product is the reason. Horses that I currently own are in their upper teens and still going strong.
Sandra S on Jul 20, 2015
Just thought I would try it but Flex Force is a much better product.
JUDY K on Jun 14, 2015
osteo arthritis
K I on Apr 9, 2015
This product has the highest amounts of glucosamine, chrondroitin, and hyal. acid of any product. It is very palatable and easy to feed.
MARY S on Jan 13, 2015
needed to buy for my gelding that has ringbone
Christina H on Dec 22, 2014
I purchased because of the good reviews and I needed this type of supplement in a pellet formula. Tried another supplement with somewhat the same Ingredients but it was in powder format and my horse would not eat.
BIANCA B on Dec 1, 2014
Great product. Love that it's pellets.
Susan K on Oct 11, 2014
I have a 19 yr. old horse with beginning arthritis. This product has really helped him and he likes the taste
R K on Oct 11, 2014
Was recommended by a friend - This has helped my horse to the point he is lame free! He developed arthritis in his hip as a result of Lyme's disease. The massage therapy was slow - incorporating this supplement into his daily diet has made a marked improvement in his demeanor and ability to participate in all our equine activities! THANK YOU!!
MARIE B on Sep 28, 2014
My vet recommended that I use a product with a very high glucosamine content because of my mare's age-related arthritis, and when I did a comparison of the various products on the market this one had the highest glucosamine content.
JULIA R on Sep 17, 2014
have a mare that needs joint replacement. Like the pellet option, instead of granules. Easier to administer
Leslie B on Sep 8, 2014
I like the pellets instead of powder none of the product is wasted. My older thoroughbred needs a joint supplement and this product makes it possible for him to roll in the grass scratch his back and get back up. Thanks Absorbine.
MARY M on Jul 3, 2014
cuz it works
SARAH L on Jun 11, 2014
Highest level of ingredients at the best price
SHERIDAN C on May 13, 2014
Great product, easy to use. I hated Cosequin as it's a pain to mix and expensive. Flex Max is a product my mare will eat without my having to worry about her blowing it out of her feed pan (picture dollar bills floating through the air) or having it sink to the bottom and not get eaten at all.
MARILYN F on May 7, 2014
This seems to work the best for my horse.
Doris R on Apr 2, 2014
This product has the best levels of the ingredients that will help my horse remain sound. He is a picky eater, but loves this supplement. I just got another horse who is older and I will now put him on it also. Good product!
KAREN H on Mar 23, 2014
We have a horse with severe arthritis in his knees. Flex Max and his monthly injections keep him comfortable and allow him to run and play.
Dannielle M on Mar 2, 2014
needed a pelleted supplement with HA for our traveling horse
Tobin R on Feb 26, 2014
good results, the vet likes it, use it on horses and dogs

How do u feed this... is it a treat? Says pellets? But says u feed a scoop. So do u mix with water I'm confused?
Ashley T on Nov 23, 2016
BEST ANSWER: The pellets are tiny, about the size of a feed supplement (such as Senior feed), the scoop is about 1-2 ounce cup that comes with the supplement. I throw a scoop of the supplement in mixed with some sweet feed or senior feed (about a coffee can size scoop) just to ensure they eat it. I have never had my horse turn their nose up to it, so it must taste ok.
No need to mix with water.
Hope that helps!
Is there a loading time or just once daily?
shelly on Sep 7, 2018
BEST ANSWER: It does state to load for the 1st week I believe, but I didnt do it. Have a vet friend who says it is not necessary. This stuff works great. Had my 17 year old QH on it for 1 year now. Took him off for a few months and noticed a huge difference!!
will this help with navicular?
debbie e on Sep 16, 2016
BEST ANSWER: A quality arthritis supplement such as this one may help navicular, depending on the severity. A supplement specifically targeted for navicular is made by Figuerola, please see the link below. We have to recommend that you consult with your horse's veterinarian for treatments for your horse's particular condition. Often it's a combination of both supplements and supportive shoeing or hoof boots.
