    Grand Flex is rated 4.7 out of 5 by 27.
    Rated 4 out of 5 by from Noticeable improvement! My horse has struggled with arthritis for a few years now and this has worked the best for him yet!

    Rated 5 out of 5 by from great price and results my horse is in full time work at age 14. she is moving great, comfortable and there's no joint swelling

    Rated 5 out of 5 by from Love this product! Works well on my show horses - keeps them very sound.
    Date published: 2014-06-02
    Rated 5 out of 5 by from Love this supplement. Great results and afforable! I've been giving this to my TB gelding for a few months now and he's doing great. He has fetlock issues due to an injury sustained while racing and GrandFlex has improved his movement tremendously. I feed it mixed with a little rice bran and he hoovers it up so he must like the taste. I also tried giving this to my German Shepherd who has some mild joint issues. She hated the taste and won't touch it. Not even mixed with her food.
    Date published: 2014-01-14
    Rated 5 out of 5 by from Good product! This is a good joint supplement and I think its really working. My "picky eater" doesn't like it as well - but my mare eats it without a problem.
    Date published: 2011-12-07
    Rated 5 out of 5 by from grand flex is great! i bought this because it was the most affordable even over smart supplements...i was skeptical when i received it because it had a bad odor but said it was apple flavored and my mare ate it up...she is 11 and has nevicular disease so i wasnt sure it would work but to my surprise it seems to have done way more than just help...she is happy and energetic so we can tell she feels much better and is in less pain

    Rated 5 out of 5 by from grand flex I love this product. My mare loves it and it is so good for her joints as she is growing and training harder.
    Date published: 2011-10-06
    Rated 5 out of 5 by from Quick and amazing results! We started our 22 yr old horse on it about a month ago, and wow, we saw amazing changes in about 3 weeks. We thought the horse was perfectly fine, no health issues, no joint issues. But once the SmartPak kicked in, she was so much perkier and her mood improved. Now she acts like a young horse again, which, sometimes gets her in big trouble! I highly recommend this supplement! The only drawback is, that she does not like the taste of it, she kicks over her grain bucket trying to get rid of it, but after all she licks everything.
