Senior Flex is rated 4.6 out of 5 by 141.
Rated 4 out of 5 by from My Seniors are Still Going! I own three older horses, ages 21, 23, and 27. Although they all have slight issues with soundness, these are manageable, and two of them are still showing in lower-level dressage. This product contains all the proven "good stuff", at a reasonable price.

Rated 5 out of 5 by from Senior Flex My trainer recommended this product for my 11 year old OTTB and I'm glad she did! He doesn't appear to be as stiff as he was and I don't hear anymore "popping" which is a plus. I would definitely recommend Senior Flex to everyone.

Rated 5 out of 5 by from Great product I put my aging gelding on this after seeing how well it worked with our old mare. She went from being crippled with her arthritis to running around the pasture like a 2 year old again. I know it will work well on my gelding. I highly recommend this product for all aging and old campaigners.

Rated 5 out of 5 by from excellent product I have been using senior flex on my 13 yr old fjord gelding for 3 years; he has coffin joint arthritis in his right front leg. He is sound and comfortable. Had recently read positive reviews of this product in Horse Journal

Rated 5 out of 5 by from Great Product I really love Senior Flex. I have been using is for 3 years and my horse does great on it and he loves the taste. My horse is 20 years old and acts like he is 5. He has a lot of get up a go and I credit the senior flex. I would recommend this product to anyone who has a horse in their senior years.

Rated 5 out of 5 by from Works wonders! Great product. It's a great value for the money. I love that it also has Ester-C and probiotics in it as well. Did lots of comparing and this one was the most bang for our buck. Really helped the joints of our slightly arthritic gelding and growing sport horses!

Rated 5 out of 5 by from SR FLEX I just started the product so it is to soon to tell. But so far things seem good.

Rated 5 out of 5 by from Great for jumpers! This product has keept my daughter's 21yr. horse jumping high! No squeaky joins and no stiffness! Low price and works great!

Rated 5 out of 5 by from Woohoo! My horse is very picky about his supplements, and he actually eats this. Not only that, but my 21 year old TB would look as though he's walking on eggshells when heading out to the field, and now he's at the head of the pack, usually prancing or at a full out gallop (with a few joyful leaps and bucks thrown in). It makes me feel good to know how great he feels since using this supplement!

Rated 5 out of 5 by from lONG TIME USER I own a 31 year old Arabian mare that I have had since she was 16. Around the age of twenty she started to slow down and our Vet suggested a joint supplement. After much research where I considered cost vs. ingredients I was looking for, I chose Senior Flex. My mare has been on this supplement faithfully since then. We still trail ride several times a week and she is doing great! No one thinks she is as old as she is. In fact, I had a Vet out for an emergency call this winter for a wire poke to the eye area. She thought my mare was in such good shape, she was the topic of her next in service on the senior horse! I will continue to keep my horse on this product hopefully for many more years.

Rated 5 out of 5 by from Good Supplement My horse is a 23-year-old thoroughbred, a racehorse turned hunter. He still works 4 or 5 days a week, though not like he used to. I believe the Senior Flex from Smart Pak helps keep him from being very stiff and also gives him energy. People cannot believe he is 23.

Rated 5 out of 5 by from Senior Flex Senior Flex, is by far the best supplement I have ever used on my horse. He is a 28 year old Quarter Horse Gelding that sustained a knee injury when he was 17. When I got him, he was so lame at the walk he was painful to watch. After many trials an errors, he now gallops everyday! I have never been happier with any other product! I would reccomend it to anyone with a senior that needs a joint supplement. Smells great and he loves it!
Date published: 2009-05-16
Rated 5 out of 5 by from Won't go without it! I have a 27 yo OTT Tb. mare who is still competitive in HUS and O/F and in wonderful shape! No one believes she is a "golden oldie!" Senior Flex combines all the right ingredients for an older horse at a wonderful price, and the stable owner doesn't have to scoop from a variety of tubs. I recommend this product to anyone with a horse over 12. Happy riding!
Date published: 2009-05-05
Rated 5 out of 5 by from Great Purchase This product has kept both of my older horses in great shape! They are both in their late 20's and still running around the pasture feeling spunky!
Date published: 2009-05-05
Rated 5 out of 5 by from Great Product We've been using Senior Flex for about five years and are very pleased with the results. We have done price comparisons in our area and SmartPak is also the most affordable way of providing supplements. It arrives on time each month and we never worry about a thing.

Rated 5 out of 5 by from Good for the old guys I find this supplement to be the best buy for the money and has really helped my 22 year old Hanoverian, and my 21 year old Trakehner...they move more freely and just seem more comfortable in general.

Rated 5 out of 5 by from Love This Product I love this product for my Saddlebred. Who is turning 27 this month. He suffers from arthritis and his legs swell up in the winter months. He has alot of pain just walking around. I previously used Senior Flex and decided to try other brands on the market. Not only were they more expensive, but after many months of failure. I came back to Senior Flex. Nothing compares to Senior Flex. I will keep him on this product from now on. It provides him with so much relief and comfort. He acts much happier now and his legs look great. There is no need to look for a better product. You found it.

Rated 5 out of 5 by from Great for the senior horse I really like this supplement. The large amount of Yucca seems to work the best out of anything that I've tried for my 18 year old OT TB. When I was working 1/2 time I tried to save a bit and took him off of it and the difference was significant. He is much more comfortable and fluid moving.
Date published: 2009-04-28
Rated 5 out of 5 by from Excellent Joint Supplement My 18 year old Miniature Horse had an old stifle injury with arthritis. Had tried other joint supplements, but after 1-2 months on Senior Flex she is running and bucking around the pasture! Before she could only manage a trot. I highly recommend this product!
Date published: 2009-04-27
Rated 5 out of 5 by from Senior Flex People question the value of giving horses oral joint supplements--some say they don't work. My 29 year old gelding has been on Senior Flex for about four years. He still runs and kicks up his heels like a youngster despite his arthritis. I think that Senior Flex deserves at least part of the credit.
Date published: 2009-04-27
Rated 3 out of 5 by from not palatable I like the mixture available here but think the MSM affects palatability. While my 30 yr old gelding started out eating it after a couple months he turned off and wouldn't touch it. Not on it long enough to see the benefits.
Date published: 2009-04-24
Rated 5 out of 5 by from great combination product My competitive 18yo TB is on this product and I love it. I like that it has both glucosamine and MSM in it along with some digestive help in the lactobacillus. Great product for the money.
Date published: 2009-04-20
Rated 4 out of 5 by from Bridges the gap I have 2 horses on this product who are both in their low 20's. Any signs of stiffness are gone and they both act a lot younger.I do believe that this product has really helped them deal with age related stress. My almost 31 year old horse ( recently put down due to congestive heart failure) was on it for almost 3 years and was still being used in a lesson program up until one month before he died. this product was a really great bridge in giving them all joint comfort and also helps with their overall condition. For horse with dramtic joint issues you would need to go to something stronger, but for my guys this does the trick.

Rated 5 out of 5 by from Super! We have an older mare with arthritis. She has days where she is very stiff. She is really responding to the Senior Flex. I have noticed a spring in her step and more flexibility. I would recommend this product!
Date published: 2009-04-09
Rated 4 out of 5 by from Really Works We have a retired Throughbred that had been used for hunt/jumping and dressage and the effects of that are showing in latter life. Sr. Flex keeps her active and helps her not to be so stiff.

Rated 5 out of 5 by from Great product I have been feeding this to my now 26yo Morgan for 2 years. My farrier cannot believe how good my horse looks! I am still able to drive my horse and do some light riding. No product is going to reverse the arthritis in his fetlocks and hocks, but this product has kept him comfortable and mobile despite his age. He is a bit picky about eating it (not sure if it is a flavor or texture issue), but I use a liquid fat supplement anyway and that seems to help "stick" the SeniorFlex to his grain ration so he eats all of it. Great supplement for a reasonable price.

Rated 5 out of 5 by from This product works MIRACLES! Before Senior Flex. my old (32) man was retired. His arthiritis had gotten to the point that he could not comfortable be ridden or even lead around for a leadline lesson. I figured I try the Senior Flex after doing some research on joint supplements. Within a few weeks, Stormy was able to return to his job teaching little kids how to ride. Granted, his work load was very small, but he was happy to be back with the kids again. He even taught a few how to lope! On top of the joint benefits, he was able to put on weight and keep it on, which had been a struggle before Senior Flex. I've used this on a number of horses since Stormy, and have seen the same results every time. Now I tell everyone I know with a horse over 15 that they should try it.
Date published: 2009-02-05
Rated 5 out of 5 by from Senior Flex Works I have an older gelding (approximately 19) and I've had him on Senior Flex for almost 2 years. I noticed a difference after the first few weeks. He is definitely more flexible and not as "achy" on those cold or damp days. You can also see he feels better when frolicking out in the pasture. I tried using another joint supplement for a few months, but didn't see any greater improvement from the Senior Flex; which was also substantially less expensive. I know Senior Flex works, so I switched him back.
Date published: 2008-09-25
Rated 3 out of 5 by from Like Not Love My vet said he felt the probiotics weren't necessary. Otherwise it seemed like a good blend for joint health. No complaints, but not wild about it either. Does tend to sift out of the grain because of powder consistency.

Rated 5 out of 5 by from What a difference!!!!! I have a 13 year old Paint mare with a serious pelvic fracture that left her sore and bow legged. It was a challenge to find anything strong enough to help the pain and discomfort. I put her on this product, reluctant that it would never work and that I probably wasted my money. Boy was I wrong!!! She used to not even be able to walk out of her stall without nearly falling down and now she springs out like she had only been in there for five minutes. I switched her off once, and she went instantly lame within two days, put her back on and it worked like a miracle. I'll never switch again. Thanks MVP for such a great product!!! Nothing like it on the market!!!
