    MSM Pellets by SmartPak is rated 4.7 out of 5 by 373.
    Rated 5 out of 5 by from So happy this comes in pellets! I was previously feeding my horse the MSM powder, but because he gets some other powder supplements, I wanted to change anything I could to pellets for palatability. I feel more confident that he's eating his supplements now and getting the support he needs.

    Rated 4 out of 5 by from Pellets are crumbled The pellets are somewhat crumbled appart so picky eaters may not eat them. However my horses are fairly picky but did eat them.

    Rated 4 out of 5 by from Good product! My 31year old has been on this for 2 months and seems to be doing good. Helps him get around without pain or discomfort. He eats without a problem and he's a picky guy

    Rated 5 out of 5 by from Does it's job! Due to my pony and I being involved in the world of Eventing, my boy needs joint support as a preventative measure. A horse only has so much jump, and I firmly believe that what we take out of them, we must put back. Eventing is a very demanding sport on our horses joints, and SmartPak MSM Pellets does a fabulous job in supporting my best friend and his joint health. The pellets allow me to have peace of mind, knowing he is ingesting the full dose required for the day. No powder being left at the bottom of his bucket, and no wasted feed due to a picky eater knowing it is in there. I will always ensure my buddy has his SmartPak MSM Pellets in stock.

    Rated 4 out of 5 by from Smell good I purchased for a specific horse but he didn't like it. No surprise, he is the pickiest eater so I am using the pellets on an older horse who likes them.
    Date published: 2017-03-01
    Rated 5 out of 5 by from Easy to eat I feed pellets to my horses instead of hay so the horses can't tell the difference when I feed them these pellets. I've tried other MSM & they would leave it in the trough.

    Rated 5 out of 5 by from MSM Supplement I started my horse on these smartpaks about 2 months ago and I already see a huge improvement! I give him these to put off getting his hocks done until he FOR sure needs the injections. My gelding is more willing to go forward, can easily move his back legs and is less grumpy when we warm up. Amazing !
    Date published: 2017-01-10
    Rated 4 out of 5 by from Too soon to tell I started supplementing my gelding who has a thoroughpin. I am hoping that it will alleviate the swelling of his tissue on his back hock. It is too soon to know if it is working as I have not seen any dramatic change yet.

    Rated 5 out of 5 by from Very palatable for my picky eater. I bought the MSM pellets because my horse would not eat the loafers I had tried. He loved the pellets and they seem to help give him some relief from his DSLD.

    Rated 5 out of 5 by from Great value! My older mare seemed to really benefit from this product. I tried it in conjunction with another powder joint supplement (which she didn't really care for) that didn't include MSM. I decided to switch to smartflex senior as it was cheaper than both combined, but would highly recommend it for a maintenance joint supplement.
    Date published: 2016-08-29
    Rated 5 out of 5 by from Great Job! Use this for my mare that was diagnosed with EPM before I bought her. She is free of EPM, however I just want to give her system a boost, so this was recommend for horses that had EPM. She loves it, that's whats important!
    Date published: 2016-08-16
    Rated 4 out of 5 by from Easy to feed! My gelding has been on MSM pellets for a month. His heaves have been improving over that time. Although he takes other supplements and medication, I did notice an improvement since starting MSM. It's easy to feed and is great tasting.
    Date published: 2016-08-01
    Rated 5 out of 5 by from Great Results Bought this as a recommendation for horses that had EPM, my Mare has no signs of it, although It's highly recommend she stay on MSM.

    Rated 3 out of 5 by from Great product, Does not last I bought this product on 3/24/16. My horse was the only one receiving the loading dose (one scoop that was included once a day). I was the one making up his food. I found that it did not last the 56 days but is already gone. I started a few days after the order was placed so roughly 3/27 was his first dose. It was gone by 4/27. I love this product but hesitate to spend the money knowing it isn't going to last the full time.

    Rated 5 out of 5 by from MSM our horses will eat I have not had success giving powdered supplements or granular MSM, but they both eat this with their maintenance grain. It can help joints and hopefully help some with inflammation in our older horse's lungs or "heaves"

    Rated 5 out of 5 by from Definitely see improvement MSM pellets have really helped my pony during show season. He is less sore and even his hooves are stronger. Hopefully keeping him on these will see even more improvement. Great and affordable supplement

    Rated 5 out of 5 by from MSM Pellets are the best! My horse loves them, super easy to feed. He thinks they're a treat! No more messy powder to deal with.
    Date published: 2016-04-12
    Rated 5 out of 5 by from No More Cracking I bought this product almost two months ago for my 10 year old Paint mare. She was a little stiff and even lunging in the round pen she would snap, crackle, and pop. Although I have used her in the past for local team penning competitions, she really was used mostly for trail riding, so it seemed odd to me that she would be having joint issues already at her age. None the less, I decided to try a joint supplement on her. I didn't know if I should spend my money on the more expensive supplements because although she was a little stiff, she didn't have chronic joint or lameness issues. I decided to take my chances on a cheaper supplement based on the reviews of MSM by SmartPak and I am so glad that I did! Although it took a solid month to see the difference, I no longer hear cracking as my horse moves about and she has become much more supple and flexible. I have been stretching her as well so I am sure that helps, but the snaps and cracks are gone! I would definitely recommend this supplement for those who are looking to prevent joint issues and fix minor ones like my mare had. Give the supplement at least a solid month to work. I can not speak on how the supplement would work on extremely bad joints, but I can say with confidence that this will work for younger horses with beginning stages of joint and stiffness issues. **Oh and as a side note .. My mare is VERY finicky with what she eats (there are days she wont eat an apple because it smells different) and she eats this no problem with either her grain or a little alfalfa pellets.
    Date published: 2016-04-12
    Rated 2 out of 5 by from Not sure if it is working My ottb has been on this for 1.5 months now because her hocks were stiff (only noticeable when hoof picking her hind legs) and nothing has changed so far. If I don't see any results in the next couple weeks I am going to try a supplement with glucosamine instead.
    Date published: 2016-04-06
    Rated 5 out of 5 by from Great Results I use this product in addition to the SmartFlex Senior as I wanted a little more MSM than what that product offered. Having a white pony, he's prone to goopy eyes and a few other ailments that MSM can help plus a little extra for his joints couldn't hurt either. I've been pleasantly surprised with this so far. My pony hates powders, but has never had a problem eating every bit of these pellets. Plus the results in his eyes alone speak for themself.
    Date published: 2016-03-26
    Rated 5 out of 5 by from Pleasant surprise and great results. Mostly... I've had my 21 yr old TB gelding on this for two months in an attempt to alleviate mild stiffness out of the stall and to support his hocks and stifles. This is the only supplement that was added and there were no changes in work or environment during this time. It was a cool winter but the temps stayed steady without major fluctuations. Here's our result: Day 1 - 3: no significant change Day 4 - 14: He appeared "brighter" and more energetic & vibrant over the week, if even a little hot, possibly from feeling good. Hock action on longe was improved. Weeks three and four: Much more forward, started to use himself better, worked out of his normal stiffness in about 15 mins instead of the usual 20. Seemed jittery and overly alert but still manageable. Month 2: Solid works with good forward movement and getting his lofty trot back, skin issues/propensity for rain-rot seem diminished. Jitters subsiding but still noticeable. Has become a royal nuisance in the pasture bugging all the younger horses and wanting to play. Sighh. Can't have it all.
