Senior-Flex™ Powder is rated 4.6 out of 5 by 142.
Rated 5 out of 5 by from Life Saver! I recently had to put my two senior mares through another move to a new property. My 29yr old suffered from severe stress due to the move and lost more weight than she could afford to. I took the SmartPak quiz and found this as a cheaper option to what it had suggested. I firmly believe that this product is why I still have her with me! She put weight on fantastically (and we all know that’s hard to do with older horses) and her coat is starting to grow back thicker just in time for cooler weather!

Rated 5 out of 5 by from Horse loves it! Long term platinum CJ user - bloodwork shows that balance does not work for her anymore. Needed a new joint support and this ticks all the boxes! Similar consistent and smell to CJ as well and fussy horse eats it all!!

Rated 4 out of 5 by from Great features I'm glad I found a joint supplement that my horse will eat! I can smell the yummy as soon as I open the pak

Rated 2 out of 5 by from Not sure if it helps Started about 2 months the heat has gone down in her joints but I still see discomfort when she walks

Rated 5 out of 5 by from Senior Flex I have been feeding Senior Flex for about 1 1/2 months to my 3 seniors. They are showing more flexibility and much less stiffness.

Rated 2 out of 5 by from Senior horse would not eat this product. Senior horse would not eat this product. Smart Pak kindly replaced it with the house brand in pellets.

Rated 4 out of 5 by from Loved the taste! I had to separate feed time because my younger horses wanted to eat this all up.
Date published: 2017-08-01
Rated 5 out of 5 by from Senior Flex for Maintenance I started Cheyenne on Senior Flex about 6 months ago to help prevent any joint pain or injuries. It seems to be helping my horse who will be 11 years this year. I will continue to use it as long as I am seeing improvement!

Rated 5 out of 5 by from Chancy Tru loves senior flex. My 20 year old Mare. Chancy has hip problems and was really stoved up. With Senior flex she feels much better and can actually kick up her heels some..
Date published: 2016-09-08
Rated 4 out of 5 by from Has everything she needs! My 24(?) year old mare needed something more than the Butlers pellets she was on to manage her mild arthritis. This supplement has good amounts of everything i was looking for (MSM, glucosamine, etc) with the added bonus of antioxidents for her immune system and probiotics. Don't have to supplement in probiotics for her anymore which is great because she will only eat so much extra "stuff" with her grain. She's picky and eats this well
