    SmartFlex® II Support Pellets is rated 4.6 out of 5 by 278.
    Rated 5 out of 5 by from Great Product I purchased a late 2 yo warmblood gelding last fall and immediately started him on this product. He is very growthy and I am a believer in prevention! He is doing what he should be as a 3 yo with no issues!

    Rated 5 out of 5 by from Great for my senior My 22 year old is in minimal to no work through winter and into spring and this keeps him moving well in his pen. He has some arthritis in his hocks and defiantly has troubles If he doesn't have joint supplement to help. This was a great option for him until summer will come along and I will have to move him up to a higher level of support. Will use this again next winter. He is a picky eater and he eats any of smartpaks pellets right up. :)

    Rated 5 out of 5 by from Protects precious joints!! I have had my 7 year old appendix mare on this joint supplant going on a year now. We compete lower level hunter/jumpers and eventing. Knock on wood, my horse has not had any injuries when it comes to her joints. I really do feel like she has a invisible protective shield around her legs that helps prevent any issues. I love this supplant and it comes in pellet form...yay! She eats it up. Love this product

    Rated 4 out of 5 by from Don't recommend the largest bag I have been using this supplement for about 7 months and usually I buy the two month supply bucket. The last time I ordered I went with the largest 4 month supply bag option so I wouldn't have to order as frequently. The amount of pellets that are ground up is annoying and I'm disappointed. I feel like it makes it difficult to give my horse the correct amount of this supplement. Aside from this issue I do like the supplement and have seen a difference in my horse.

    Rated 4 out of 5 by from Good Joint Supplement I cant say exactly about this supplement. The horse that I have put it on is a 6 yr old Thoroughbred. He is long in the pastern and has windpuffs and a spint on the front. In other words he plays hard.I put him on this to support and to help prevent any joint issues. This seems to cover all the bases for the $, as in ingredients.But I can say that he is a real picky eater and he doesnt mind eating these pellets!

    Rated 5 out of 5 by from Perfect for my show mare in moderate work! I like that this supplement offers more than the typical maintenance. It supports and protects my 8 yr old mare's joints from everyday stress and keeps her moving free and comfortable.

    Rated 5 out of 5 by from Great suppliment We have just entered our second month of using this suppliment and already I can tell a difference moving from his old suppliment to this one. He has nice full extension at the trott. I can just tell he feels good because he is energetic and collwcts up nicely. He never leaves any in his bin and nine is wasted as with the powdered supplements.

    Rated 4 out of 5 by from Works for alleviating pain In one month of using this I can tell the difference in my horse's joints. He used to move with an uneven stride to avoid stress on his hind legs but now he is using his back legs and doesn't fight the canter! I can always tell when he is off, and a month of this snapped him out of his offness. I only say its good because I only tried it on my one horse, but he does have a pretty strenuous workload. I do not know how effective it would be for other horses.

    Rated 4 out of 5 by from Noticed improvement I bought this for my 11 year old mare who has some stiffness in her hips. I have been feeding her 1 scoop/day for about 4-5 months and I've noticed improvement. I used to hear some clicking in her movement and it has been reduced after a few months on this supplement. I get the pelleted version and it is easy to feed, I never notice any picky-ness whereas I sometimes have trouble feeding her powdered supplements. I would recommend this product as an affordable option for mild stiffness or other similar mild issues.

    Rated 5 out of 5 by from Picky Mare Approved!!! It took lots of sampling to find the joint supplement that had features I liked and was in a formula my picky mare would eat. I love that it gives her such wonderful joint support without breaking the bank. She moves great on it, no stiffness issues at all.

    Rated 4 out of 5 by from Very palatable and Easy!! We are using smartpak as a preventative measure, but the horse loves it and so do I. She's a very picky eater but never even notices the pellets are in her feed.

    Rated 4 out of 5 by from My horse (12yo American Warmblood TB/QH/Perch gelding) is moving around a lot more even with the cold weather setting here in Maine. He is much more playful and active.

    Rated 5 out of 5 by from I was skeptical when I signed up for smartpak. But now I'm glad I did. My mare has issues with her stifle and the vet and farrier both recommend joint supplements. The Smart Flex coupled with corrective trimming and hill work is giving me my 5yo horse back. I'd recommend this to anyone who's horse has joint trouble.
    Date published: 2014-12-02
    Rated 4 out of 5 by from Love it! I started my mare on this when she started "hopping" around her barrels. She was always smooth and easy around them and then when I started her back after a little time off, she would almost fall down or she would get really choppy. I decided to put her on this and we are in our second month. Loped her through a few times just yesterday and she was better than ever. The only thing is that she doesnt like the taste of them alone. I had planned on just giving her the supplement because she can stay fat on air, but I guess a handfull of grain won't kill her! Overall I am very happy with this product!

    Rated 5 out of 5 by from great product I really like the product however I prefer the pail to thesmart packs the piece are bigger and not as crumbly.When the pieces are bigger she eats it all up but if it crumbles she leaves the crumbs but the product is excellent.
