    SmartFlex® I Maintenance Pellets Original is rated 4.7 out of 5 by 269.
    Rated 5 out of 5 by from Great Product for the Price! Switched my QH/TB gelding to this from Cosequin ASU. This product is much cheaper, easier to feed, and works just as well, if not even a little better.

    Rated 5 out of 5 by from Best value around I switched to this after a price increase on my then current joint supplement and couldn't believe how much I'm saving and it's not super messy like the liquid I was using ++ for everyone.

    Rated 5 out of 5 by from Helps so much! My mare has been on this for 2 months now and she has never felt better. no stiffness in her back legs which has made getting back into work, and shape, into a much more enjoyable experience.

    Rated 5 out of 5 by from Made a big difference! My 9 yo rescue gelding was showing signs of soreness in light training. I had my vet/chiropractor out and she adjusted him, and suggested we get on a joint supplement to help maintain him. After several months of SmartFlex, I am very happy at how comfortable he's been. I signed up for the automatic order, and love the discount! You can't beat Smartpak's customer service either.

    Rated 5 out of 5 by from Makes a Difference! I've had my gelding on SmartFlex Pellets for 3 months, since learning he had a previous hock injury. Within just a few weeks he seemed more relaxed when asked to trot, and now his stride is smooth and even. Thank you, SmartPaks!

    Rated 5 out of 5 by from Helping Horse with arthritis I started giving my horse this supplement two months ago, after noticing and confirming with my vet that my horse was having mild problems with her hocks. I wasn't a big believer in supplements, but I'm always willing to try new things to see if they are worth my wild. Though I can't visably see a difference, when my farrier came out this past week, he noticed that she was more willing to stretch out her hocks when he trimmed her. As a result, I am now a believer!
    Date published: 2017-08-12
    Rated 5 out of 5 by from Good basic supplement I bought this to help a little mare that was given to me who was out of shape and over weight. She was a little stiff to move and seems to be getting along very well on this.
    Date published: 2017-08-04
    Rated 4 out of 5 by from Feeling good again Started my 22 year old quarter horse on this back in May and now he doesn't seem to be as stiff in the mornings and he is even trotting around more in the pasture. I'm sure he is feeling good again!
    Date published: 2017-07-01
    Rated 5 out of 5 by from Drastic Improvement! I've had my gelding on this supplement for over a year and I couldn't be happier with the results! Sometimes he gets stiff in his hind legs due to lack of exercise or cold weather. This supplement has taken the soreness and discomfort out of his hind end. He moves so much nicer now, and seems much happier and healthier!

    Rated 4 out of 5 by from trying to get some joint support into my horse I am boarding three horses at two different stables. I visit one stable daily and the other once or twice a week. I need to give the horse I don't see as often a joint supplement because he is recovering from an injury. Smart Paks was a good way for me to go because it's easier for the barn manager and the price was competitive.
    Date published: 2017-02-16
    Rated 5 out of 5 by from Excellent product! My horse has been on SmartFlex Maintanvw for a little over a month now. I started her on this due to an old injury and it making her stride just a little off in the back end. Since starting this supplement she is back to full form! Back to her natural, high action stride that I and everyone who meets her loves so much about her! I couldn't be more happy with the product!

    Rated 5 out of 5 by from You make her feel so young! This product is wonderful and my senior mare feels and acts so much younger since she has been taking SmartFlex Maintenance 1. She has more spring in her step and has been wanting to jump crossrails. She has always enjoyed trails but now she acts even happier and finds her gaits and speeds up with pleasure. This supplement has made my gaited girl feel so much better and I feel better knowing she isn't moving stiffly now. She is a picky eater but has no issues eating the pellets.
    Date published: 2017-01-25
    Rated 5 out of 5 by from Less Stiffness Horse was having stiffness and occasional swelling. She's 13 so I wanted to get ahead of this before it gets worse. Mare has had no swelling and warms up much quicker since using this product.
