    SmartFlex® Senior Herb-Free Pellets is rated 4.7 out of 5 by 363.
    Rated 5 out of 5 by from Easy to feed I bought this for my Clyde cross mare when she was diagnosed with a stifle issue. It not only works , but overall her disposition is calmer and less stressed when in her stall due to bad weather . It took about two full months of building up into her system however, it was worth the wait . Due to her being 1,500 pounds , she is on a custom dose of three wells . I say give this product a try but do give it some time . My horse is more comfy and I am happy she no longer needs injections or a harsh prescription to keep her at a comfortable level of health .

    Rated 4 out of 5 by from Great features I am so glad I switched to the herb free. My mare seems to do better on this one.

    Rated 5 out of 5 by from Best Senior Supplement! I have been using this for a while now and I have tried all the senior supplements and my poor pony never changed, until I tried this one! He no longer limps from his arthritis and has more energy!

    Rated 5 out of 5 by from Really needs the full dose I have an 11yo TB mare that I wanted on pretty comprehensive joint support as she's been jumping her whole life. I had her on this, then to save a couple bucks I dropped her down to a custom dose of only half the recommended dose. That was a mistake! Within 2 weeks I noticed she was cracking and popping when she got up from laying down. I'm adding this back to her regular SmartPaks as I never noticed this while she was on the full dose. My mare gobbles it up without an issue.

    Rated 5 out of 5 by from It must be Delicious! my senior horse takes an oral med for arthritis. He hates it. I tried hiding it in his food. I tried hiding it in his food with syrup. I tried giving it with a peppermint. I tried giving it inbetween two peppermints glued together with syrup. I tried shoving it in an apple. Finally resorted to shoving it way back in his mouth with my hand, but he was really good at working it back out and spitting on the ground in front of me. One day I got smart and hid it in a few grains of the SmartFlex Senior Herb-Free supplement and he gobbled it up!!! No more problems, he takes it like a champ.

    Rated 3 out of 5 by from Early Days Haven't had time to see any results yet, but I like the herb-free feature and especially the pellet form. Too much waste with granular joint supplements.

    Rated 3 out of 5 by from Great Ingredients, Not Enough Results I tried this supplement on my 13yo Warmblood Cross who like most Warmbloods have early bone growth on his hocks. I wanted to get out ahead of any more progression. This had all the ingredients I was looking for, except I did not notice a significant different to keep paying this amount. I decided to go with Adequan instead. The loading does once a year seems to equal out to the same as an oral supplement and I have seen instant results.

    Rated 5 out of 5 by from It's working! My gelding has been on SmartFlex for about 2 months, and I already see a difference. He is only 11, but has joint issues and has had lameness in his his right hind from an old injury. After starting him on SmartFlex he is significantly less stiff and the popping and cracking in his hind end has reduced as well. I would definitely recommend.

    Rated 5 out of 5 by from Spring back in his step! My 20 yr old QH was getting very stiff in one of his knees. Noticed with trimming. And was clicking more in one of his back legs. He’s always been very active running horse all the time still was but noticed more walking to come see me then running like he always did. Thought I’d give this a try. It’s amazing difference in short time. And he’s back to his old jokester self Just generally feeling very good again.

    Rated 5 out of 5 by from Very palatable, I like the ingredients It's too early to notice if it's really working, but I ordered this a few months ago and my horse seems to like it. He is not quite as stiff as he was. He enjoys eating it.
