    SmartFlex® Senior Pellets is rated 4.7 out of 5 by 1517.
    Rated 5 out of 5 by from Zak loves his new supplements The pellets are easy to fed and my older Arab gelding eats them right up. The auto ship feature is not only a good savings but he will never be with out them. That gives me peace of mind. I look forward to many more trail rides with Zak thanks to SmartPak.

    Rated 5 out of 5 by from I Love SmartFlex Senior! I've been getting this for a while now and can so tell the difference! My mare has been a great horse for me and has taught me so much. Now she has a knee problem that prevents me from riding her; but she still follows me around the barn and gives me lots of love and kisses. SmartFlex Senior has helped her tremendously. She stays comfortable and still can enjoy her pasture. Thanks so much SmartPak, from Cutter and I both!

    Rated 5 out of 5 by from Acted 10 Years Younger I bought this for my 23-year-old gelding because I noticed that he was losing some muscle mass along his back and butt as well as some stiffness in his back legs while riding him. Before this, I was not really a believer in supplements but after trying this out for around 6 months I can say without a doubt that it helped him tremendously. He came back to life! He kept his weight on and began to build back muscle and the stiffness was significantly reduced. I only stopped giving it to him when I realized that some of the herbs we not allowed if you wanted to show your horse. When I found out I immediately switched the herb free version which we are currently in the middle of trying out, fingers crossed its as good as the original!

    Rated 5 out of 5 by from Horse loves it I bought this product because of all the combined ingredients for joint health. My horse loves it mixed with his grain though I find the pellets to be a bit sour smelling (probably due to the glucosamine).

    Rated 4 out of 5 by from Good for seniors. My 17.5 year old still loves to go XC. Great energy, hopefully this senior supplement will keep him moving!

    Rated 5 out of 5 by from Good Product I have been using this on 1 pr more horsed for 10 years. I try to never run out of this additive, but I don't have it autoshipped . I believe my horses are more comfortable with it. I buy it by the bag instead of the smart-pak, to be Enviromentaly Freindly. I wish I could get the discounts the the paks get.

    Rated 5 out of 5 by from Worked a miracle for my senior girl My old lady (now 25 and with two bad hocks) was having a hard time getting up and I was getting phone calls about her lying down. I started her on this and within days she was getting up no problem. When I ran out, I went to something else (thinking the prevacoxx was the reason she improved) and she was again having problems getting up. I switched her back to this and again she was able to get up no problem within days. She will be on this forever. I recommend it to everyone.

    Rated 5 out of 5 by from Wonderful product! I've been ordering SmartFlex Senior for many years for Sebastian. This guy is 33 years old and will take you for the ride of your life if he gets his head. Yes, he's skinny, but still going strong. I attribute a good deal of his condition to SmartFlex Senior.
