To keep my horse pain free.
Dawn K on Apr 7, 2019
My 20 years young mare has RINGBONE in her front left coffin joint. This product seems to keep her sound along with having removed her shoes about five years ago and having her barefoot except when ridden at which time she wears the Cavallo “glove” on both of her front hooves.

FlexMax has all of the joint-sustaining ingredients I like to use, and is pelleted and palatable. Good product!
Katherine H on Feb 6, 2019
I have horses in their late teens to 30s, some with joint issues. I believe this product helps keep them more comfortable.
kim f on Feb 5, 2019
works great
Melissa R on Jan 30, 2019
Did a lot of joint supplement research for my soon to be 22 year old. According to vet & scientific data, Absorbine Flex Max was the only joint supplement with the proper amounts of the individual joint ingredients (ex: glucosamine, chrondroitin, MSM, HA, etc.) for which the ingredients would actually WORK. Most other supplements on the market do not have enough of said ingredients to be effective to the horse's joints.
ALLISON H on Jan 19, 2019
My 18Hh+ Percheron gelding has arthritis in his knees. The cold winter weather really affects his mobility. These pellets are a blessing! He feels and moves so much better when on these pellets and State Line Tack has the best price for them!
morgan S on Jan 17, 2019
seems to work
APRIL F on Jan 16, 2019
Because I think this product has the best amounts of glucosamine and chondroitin after researching this-- and I have some horses in their late teens that have had some soreness issues. I feel this product helps them stay sound.
kim f on Dec 13, 2018
has all the ingredients identified to help joint soreness/stiffness.

Good product at a reasonable price.
Dennis J on Nov 15, 2018
This has worked wonders on several of the horses at our barn. One with arthritis, and another that has previously had her hocks injected.
James R on Nov 8, 2018
my mini has a stiff stifle and these pellets are awesome! he loves them too!
Lisa R on Nov 5, 2018

Great product.
Robert T on Aug 31, 2018
My senior citizen needed some joint support so based on the ingredients and reviews thought we would give this brand a try.
Patricia M on Aug 22, 2018
My horse had an infected elbow joint and I hope to keep it moving for her without arthritis. She likes the taste.
CATHERINE H on Aug 8, 2018
I like Absorbine products very well. The company is very supportive of charities and has supported mine in the past as well. This particular supplement also had some additional ingredients that I thought would help my horse.
Joni Z on Aug 7, 2018
I have read great reviews on it.
Nina P on Aug 6, 2018
It works well for my horses joint problems.
Eva B on Aug 1, 2018
We compared the ingredients of this product to a comparable product, which was very expensive, and identified that they were very close. We have been using this product for over a year and it provides good joint support for our 19 year old mares.
Christina G on Jul 26, 2018
Many joint supplements in one product. Palatable, and pelletized, which my horses prefer to powder.
Katherine H on Jul 24, 2018
Have been using for years. My two geldings, 20 yrs & 22 yrs, look and act much younger than their age and I think the FlexMax plays a big part in their flexibility.
CATHERINE C on Jul 4, 2018
Best concentration of all supplements of all joint needs.
Debra S on Jun 29, 2018
recommended by the Vet works great
KAREN B on Jun 21, 2018
Used it for the first time a 2 months ago, went back to the old supplement it does not work as well a Flex Max. So I am reordering it again with auto ship.
Eva B on Jun 18, 2018
My mare (20yo) has had continuing issues with arthritis, which has been very hard on her. Using Flex Max has made a HUGE difference. She stays on this regularly now. WORKS GREAT!
Mark P on Jun 5, 2018
This has helped my senior gelding so much, he now moves around like a youngster again. I was so glad to find that Stateline had the best price too!
Kerri S on Jun 2, 2018
Good reviews and results on this product for my aging horses.
Michelle W on May 12, 2018
My mare was having recurring lameness and joint pain issues after suffering a fall. We saw a lot of improvement after using this product. As a bonus, we also saw improvement in healthy hoof growth and overall condition. We just took in an OTTB who seems to experience similar pain issues and has an injured hoof. We are hopeful this product will help both issues.
Audre R on May 9, 2018
Again, this horse has been on this supplement and I am just continuing it.
Paul C on May 4, 2018
My 25 year old mare has arthritis, and she has been on Flex Max for several years. She moves a lot easier being on it. She seems happy enough. I would recommend it to anyone with a horse with arthritis.
Kim Y on May 2, 2018
Horse had golf ball sized inflammation on front right leg that is arthritis according to the vet. This product took a very lame horse to sound again.
angie l on May 2, 2018
Have senior horses, product has ingredients that help their joints.
Cathy Q on Apr 10, 2018
Been using forever with terrific success, BUT... price has increased 33% (!!!) here since last order. Looking for alternatives.
GeezingInVA on Apr 6, 2018
My horse is now 25. It was suggested by my vet to find the product with the highest concentration of ingredients, this was it. This is a good DEAL!
Catherine L on Apr 1, 2018
My mare has been doing good on this!
kayla w on Mar 16, 2018
Recommended by my Vet. No untoward side effects and accepted readily by my horse.
George M on Mar 7, 2018
Using to help 32 year old gelding with his joints. Not sure if it is helping but figured I would give it a try! He is doing well.
Linda B on Mar 3, 2018

velma g on Mar 1, 2018
Appeared to be best product for ingredients and price.
Donna L on Mar 17, 2019
Regular use for my 5 senior horses.
Cathy Q on Feb 12, 2019
the measure included in package has a line at about 1/2 way up..... is the the dose or is the complete measure filled the proper dose?
S R on Jan 2, 2016
BEST ANSWER: My 28 YO mare has had minor joint problems; per the Vet's recommendation, I fill the scoop to the top and dose once in the AM with her regular grain. I suggest that you contact your Vet to determine the proper measure and dose times for your horse's activity level. Also, you should ask your Vet about what joint supplement he / she would recommend given your horse's medical condition(s)..
Is this safe for horses with Cushing's? My 28 year old tb mare has lost tons of weight and looks scary and was just diagnosed with Cushing's. She just started on prascend yesterday.
A shopper on Jul 29, 2017
BEST ANSWER: We would suggest consulting with your veterinarian.
