Senior Flex is rated 4.6 out of 5 by 141.
Rated 5 out of 5 by from Good Stuff! I have a 22 year-old Arabian with arthritis, and I tried several different brands of joint supplements. Senior flex is the most economical for the amount of Glucosamine per serving that I have found, and my gelding eats it just fine. It seems to help with the stiffness and everyone comments on how silky his coat has become since I started using it. Love it!

Rated 5 out of 5 by from Horse with problems? Not anymore! I started using Senior Flex on my 11 year old OTT thoroughbred. When she was given to me, she was cranky, colic-y, and so sore from old racing injuries I was told, "Oh she can't lie down anymore." Well, after 3 months she lies down, rolls, no longer chews or bites at her belly, and overall she just looks great! In fact, I believe she'd give Senior Flex 5 bucks! She's young again!

Rated 5 out of 5 by from Mr. Ed thinks it's great! This supplement seems to have everything my 25 yr old gelding needs. My parents and I love the idea of getting it in SmartPaks with the handy drawer! This way when I'm away I don't have to worry about my horse getting the right supplement amounts. For this price I was able to add a vitamin to my gelding's supplements. Some people say that their horses don't like the taste, but my gelding eats it just fine. Just the other day he was out in the pasture kicking and bucking, something he hasn't been able to do in years!

Rated 5 out of 5 by from Not Just for Senior Horses I've put my then 5 year old Paint horse on this product. I choose it due to its high doses of MSM, Yucca, and Vitamin A. I wanted the MSM, Yucca and Vitamin A to help with his recurrent uveitis, as well as preventative for his hocks. He is slightly straight in his hocks and I wanted to be proactive. Not only has this product helped his joints be more fluid, it also seems to help with his uveitis episodes. I have not had any issues with consumption, mostly since my horse will eat anything that does not eat him first, but I have noticed the smell is better - more like cake mix.

Rated 5 out of 5 by from A big help! Senior Flex has been a great help for my 27 year old Quarter Horse cross gelding. He's on a weight supplement as well, but Senior Flex has helped keep his arthritis under control, and since he's inactive during the winter, stocking up and horrible swollen tendons have always been an issue during these cold months. This year, J.R. has experienced very little swelling in his joints and his tendon areas. He's more comfortable and you can tell that his overall health is better, even through the winter muck.

Rated 5 out of 5 by from Great product! I have a 21 yr. old Arabian and I have used this product and seen excellent results. He remained a healthy weight and was not ever stiff! I have tried other products, some cheaper and some more expensive, and the best results are with Senior Flex!

Rated 5 out of 5 by from Excellent product! I have had my 28-year-old TB on this product for nearly a year and really like the results. She is normally a picky eater with supplements, but eats this just fine when mixed in her food. I have even begun giving it to my 9-year-old OTTB who just recovered from an injury (even though she is not a senior!) because I like the unique combination of ingredients. She eats it readily also.

Rated 5 out of 5 by from Excellent product! I started using Senior Flex last month on my almost-20-year-old mare and she is noticeably more energetic. She has already developed a nice sheen to her coat, and is moving out better than she has in years. She is keeping up with TBs half her age and hands taller than her on the trails. She obviously feels great, and I am crediting this product to the difference! I am feeding to her it all at once; I have had no trouble at all getting her to eat it. Thanks very much!

Rated 5 out of 5 by from Thank you for this product! Our 22 yr old gelding has multiple leg problems. We tried other products. It hasn’t even been a month since we started using Senior Flex and we see improvement already. Our horse will notice any change in feed and won't eat it. We feed this with a sweet feed as a treat. He loves the taste. If your horse won't eat it, try adding molasses on top. Thank you for the great affordable product. He's already moving and getting up easier than ever before!

Rated 4 out of 5 by from Tried It Again When I tried this product last year, my horses would not eat it. Since then, Med-Vet changed the product and I tried it again. The horses are eating it and I am anxious to see the results as time goes on!
Date published: 2005-08-23
Rated 4 out of 5 by from Great Product! I highly recommend this product to anyone with a senior horse. My 24 y/o TB has been on Senior Flex for 6 months now. This product by far has helped him the most! Trust me we have tried a few! My only reason for giving it four stars is that I hope to see it come in a pellet form soon! It would make me sneaking it to him much easier! Again, great product!

Rated 3 out of 5 by from Great Supplement/Bad Taste I have a 12yr. old gelding that will eat ANYTHING, yet he will do anything he can to eat everything but this supplement. The combination of joint support is great; I just wish it tasted better.
Date published: 2005-07-02
Rated 4 out of 5 by from Like a New Horse My 24 yr old mare was showing signs of arthritis with joint pain and stiffness. After about a month of being on Senior Flex, she was moving like she was 10 yrs younger. Three other owners have put their horses on Senior Flex since seeing her improvement. It is such a great product! I rate it 4 stars instead of 5 only because it is hard to get my horse to eat it. I have to make a small bran mash to sneak it by her. I am hopeful that MVP will come out with a pellet form of the supplement. I will keep her on it always, it's just that good.

Rated 4 out of 5 by from Good supplement I used this joint supplement on one of my horses who is an enormous pig. He ate it when it was mixed with a sweet feed that was really sticky and had molasses in it, but when I had to swich him to a lighter form of feed that was dryer and not as sticky, he refused to eat it. To fix this problem I added molasses to his feed and he eats it without a problem. I think that it made a huge difference in how he moved. He used to be stiff and I had tried adequan series and other expensive joint supplements, but this supplement seems to have the best results.

Rated 2 out of 5 by from Horses Don't Like the Taste I was excited about the contents and price of this supplement. Unfortunately, I have tried it with two of my horses and neither of them will eat it consistently. Even my food motivated horse has turned his nose up at it.
