Overview

Which horses benefit from senior joint support?

Normal aging and years of work can really take a toll on joints, causing stiffness and discomfort that can make a senior horse’s life more difficult. By providing your old friend with joint support designed to help keep him comfortable, you’re showing him how much you love him and appreciate the years you’ve shared.

Rated 5 out of 5 by from Senior pellets help I have been using the Senior Pellets for a month now and my horse is showing some improvement in joint function. I am going to continue with them and hope she continues to improve.

Rated 5 out of 5 by from Picky Eater Loves!!! I started my senior TB on this at the start of winter when I noticed him significantly slowing down. We would ride for 30 minutes before he would start moving normally and if he stood for any amount of time he was instantly stiff as a board in his legs and would have to start over in the warm up process. Now he kicks up in the field and has more life than some of the young horses on the property. He loves the taste and will beg for it. He eats it out of my hand by itself which is very unlike him. Definitely keeping him on it!

Rated 5 out of 5 by from It works for one one of mine!! Have a very well used schooling horse who is up in age. Has some stiffle issues . We tried to corrective shoe him that did not work. Vet recommended that we put him on the SmartFlex Senior pellets as it has the highest MSM Content. Within a month we could see a difference and three months later we are sound! He will remain on this product! Thanks smart pack!

Rated 5 out of 5 by from Very impressed My 25 year old TB has been there, done that! I have had him since he was 9! He raced until he was 7, and we had done jumpers, upper level dressage, and eventing through training level before being diagnosed with thoroughpin in late 2013 which led me to the decision to retire from eventing. His hocks would swell which would resolve in sweat wraps day after day. He would then become more stiff as the years went on. I had him on many joint supplements with very little result. It became very frustrating because I couldn't help my superstar be more comfortable. As time went on, I noticed a decline in his activity and his spirit. Even being 24 at the time I did not consider him a senior because his mind is as though he is still my 9 year old! I have been using smartpak for years and stumbled across this supplement in August. It seemed to offer all of the things I was looking to help make my guy comfortable. And let me tell you, I have never seen such great results like I have with this supplement. He is no longer stiff, his hocks RARELY swell. His overall attitude is happier! Our vet (who has been our vet for 16 years) still cannot believe that he is 25 this year! He does not look it, or act it. This is the happiest and best I have seen him in YEARS! We love our trail rides and have ventured out more in the fall of 2020 than ever before. Our last adventure was a hard 9 miles with many hills, and he was still going strong at the end of our ride. The group we were with couldn't believe how well we kept up nor could they believe he was a 25 year old been there done that retired racehorse and eventer! 10/10 recommend this product to anyone. Give this product a few months (I suggest 3-4) to really notice the difference. He is an EXTREMELY picky eater and I have had no issues with him taking this supplement!

Rated 5 out of 5 by from Smart Pak Senior Pellets Thank you SmartPak for making giving these hoof supplements to my senior equine beautiful Grullo horse easy. I can’t say enough good things. Simple, clean and exact.

Rated 5 out of 5 by from Keeps my horse young! My mare is 25 and she had quite a battle with Lyme disease over the summer. After rehabbing her from that, I thought it would be best to retire her. Figuring she would be happier and more comfortable on some sort of joint support (especially after the Lyme caused intermittent lameness and tender hooves) I decided to try this supplement. My mare has never in the 10 years I’ve had her, felt this good. She’s acts more like 15 than 25! And the results were so clear that my mom decided to try it for her senior mare as well! I cannot say enough good things about this supplement! To say I’m grateful would be an understatement!!
