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 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

Rated 5 out of 5 by from My horse loves it I am so happy that I bought this it has helped my horse
Date published: 2015-11-12
Rated 5 out of 5 by from Supplement fantastic, packaging not so great I've had my horse on Senior Flex for over 10 years. It's the only thing that keeps his 36, almost 37 year old joints happy. However, the recent packaging change isn't the greatest. I saved my last bucket to pour it in, as the people who help care for my horse spilled the bag twice, as it's not nearly as stable as a bucket with lid.
