    Rated 4 out of 5 by from seems to help I bought this for my older horse who crackles and pops when she starts moving out of her stall in the morning. She seems to have less snap crackle and pop from those old leg joints

    Rated 5 out of 5 by from Really helps my gelding! I've been using this joint supplement for about 6 months and can really see a difference in my 7 year old OTSTB gelding. I chose the SmartFlex Senior because my gelding had 112 starts on the track so although he's only 7 1/2, his joints are like a much older horse. This has really helped him in the way he moves. He tracks up better and is really freeing up his back nod shoulders! Love this supplement!

    Rated 5 out of 5 by from Very palatable and I can see results! I bought his a few months ago for my very active/in shape 22 year old horse. He is a very picky eater & I have a hard time getting him to eat supplements. He ate this right up no problem! He mostly is in his stall with small run for the winter. I've noticed this supplement helps him be not so stiff.

    Rated 4 out of 5 by from It works! This stuff works both as a curative and a supplement. My 16-year-old mare put her hoof through a wire fence and had cuts, bruises and pulled muscles. I bought the SmartFlex to help her heal. She was on it for a week and I noticed improvement. She has healed completely and I now give a maintenance dose. She moves like an eight-year-old, is comfortable and happy.

    Rated 5 out of 5 by from Makes my senior mare feel young again! Switched my 26 year old mare from glucosamine injects to the smartflex senior pellets. Wasn't seeing much difference from the glucosamine so that's why I wanted to try something new. My mate has never really acted her age, just a little stiffness coming out to work and in the mornings, but I am really impressed with these pellets. She's the rowdy one in her turnout group now! Her gimp/stiffness starting out is practically gone. Very happy I switched:)

    Rated 5 out of 5 by from Mare with ringbone I have an 18 yr old mare with ringbone. Special shoeing helped some, but the horse was still in pain, some days more than others. After much research on various supplements to help with pain, I decided to try SmartFlex Senior Pellets and extra MSM. She now walks without limping and is much more comfortable. I love the individual packaging, as it is so easy to use and stays fresh. She eats the pellets without waste, too. I was teetering on whether or not to put her down, as I don't want her to live in constant pain, but the supplements have helped so much, that I don't have to make that decision at this point.

    Rated 5 out of 5 by from Great results! My horse was originally on the herb-free pellets. I switched her because showing isn't really in our future. At 24, she moves like she is years younger. I'll never get tired of hearing someone exclaim, "She's HOW OLD?" after seeing her under saddle.

    Rated 5 out of 5 by from A Senior Must!! I have a 40 year old Quarter Horse that is a real part of our family. I decided to give it a try to help the old girl get around a little better. Certainly glad I tried it. She loves it (unlike others that I have tried). Although at that age she is still slow moving, I can see a bit of "pep in her step". Anything for our old girl :) Yes, it does cost a little more, but just the fact that there is absolutely NO WASTE, is the perfect solution for me to help an old friend out.

    Rated 3 out of 5 by from Just So-So After almost 2 months of daily SmartFlex Senior Pellets, I didn't notice any difference in my horse. He isn't a picky eater, but he hated these. I had to use more than his daily ration of grain to get him to eat the pellets. (He's insulin resistant, so sugary additions weren't an option.) He's 21 and perhaps it's because he didn't have any debilitating age-related joint or immune system issues, but it's really not worth it for us. I will keep him on the Smart Hoof Pellets, since they seem to be working very well.

    Rated 5 out of 5 by from Great product! My 23-year-old horse has been on this supplement for about a month. I can tell a huge difference in the way he moves. He had a slight limp that seems to be gone. He seems more energetic, too. Finally, he LOVES the taste!!
