    MSM by SmartPak is rated 4.7 out of 5 by 154.
    Rated 4 out of 5 by from good value My horse has some age on him as well as various issues as a result of hard use in his younger days. MSM seems to keep him more comfortable. Despite being a picky eater, he consumes this product with little fuss
    Date published: 2014-05-08
    Rated 5 out of 5 by from Seems to help! My mare isn't very old (only 15) and before this supplement, whenever she'd walk up to me or around me, I could hear her joints cracking. Since putting her on this, I haven't heard not one sound come from her joints. She also seems to love running and trotting around now, especially when it's time to go home for dinner!

    Rated 5 out of 5 by from Great for low to moderate work My horse has been on and off this for several months and it works great. Switching to something with a little more oomph now that his work load is increasing, but I would highly recommend this for low to moderate working horses. Also, my horse isn't a super picky eater, and had no problem eating this.

    Rated 4 out of 5 by from Picky TB unsure of berry flavor I love MSM and I think this product is an awesome value, but my picky TB was not crazy about the pellets and is unsure of the berry powder. Sometimes he eats it, but usually it's left in the bucket on the bottom. Unfortunately may have to swap back to just the traditional MSM!

    Rated 5 out of 5 by from Love this product! I started my older horse on this product and have noticed her getting around a lot better. It's cheap and SmartPaks makes it so easy to feed.

    Rated 5 out of 5 by from My 6 year old has been on this for 4 months now and it's been working great! My vet recommend it as good way to start taking care of my horse muscles now that he's starting to work and jump more.

    Rated 5 out of 5 by from Good Purchase Only been using this product for about a month or so. So far, its kept my 3 year old Appaloosa from stocking up in her back legs. She eats it just fine along with all her other supplements. I think its great for the price and will continue to use it.

    Rated 3 out of 5 by from Good stuff for the money Noticed a difference on swelling in the hocks of my old mare. She doesn't stock up the way she used to with prolonged stalling

    Rated 5 out of 5 by from Im a big fan of MSM Im a big fan of MSM and have been for many years. Having it in the smartpak makes feeding simple. I personally feel Smartpak MSM holds its own against the "big name" brands. My horses eat the supplement fine... they dont pick thru it at all. Wonderful results.
    Date published: 2013-01-22
    Rated 5 out of 5 by from Positive results!!!! MSM made a big difference for my 19 year old Pony Club mare. Before it, she was just the slightest bit "off" after a day with no work or a hard ride but after starting her on MSM that has completely gone away and she is sound as a rock! Once her work load increases, as recommended by my instructor I plan to continue feeding it along with Cosequin. She says that has been successful with her geldings.

    Rated 4 out of 5 by from msm..yes I have been using this product for over 30 days and I believe it is showing positive results. I would highly recommend it. It is also economical compared to other comparables..

    Rated 5 out of 5 by from Great value My horse has been on this supplement for years, and I love it! It has much more research behind it than some other products (and is so much cheaper), and it's healthy for more than just his joints. He's 17 now and still going really well, he never comes out stiff!
    Date published: 2012-06-17
    Rated 4 out of 5 by from Awesome supplement! Very great supplement for the price. I could tell a difference after just a few days. I think the pellets might be better than the powder because the powder sticks to the bucket but overall I love it.
    Date published: 2012-02-28
    Rated 4 out of 5 by from Get the Taste Tester First! I love all the benefits of MSM and this seems to have the appropriate levels for a good price but my usual chow-hound mare wouldn't go near the berry flavored powder. At All.
    Date published: 2012-02-27
    Rated 5 out of 5 by from really works my 14 year old Haflinger started to be a little stiff as the temperature dropped and did not want to canter after an intense workout the previous day, I started on MSM and within 3 days no more stiffness and his energy level is up big time
    Date published: 2012-02-23
    Rated 5 out of 5 by from Helps my horse with his stiff joints when i ride him it the cold weather as well as in the warm...a lot simpler then measuring it out every day.
    Date published: 2012-02-13
    Rated 4 out of 5 by from Must have My horse does not seem to notice it is there. The price makes it so worth it! I am not willing to pay the money for Cosequin yet, so this is a great alternative.
    Date published: 2012-02-07
    Rated 5 out of 5 by from Excellent product! All of the Smart Pak products I've purchased have been great quality and exactly what I expected. Thanks so much.
    Date published: 2012-02-07
    Rated 4 out of 5 by from If you horse needs MSM - try this Both of my horses found it palatable and it was convenient to add to their meals in the Smart Pak well. A good value if your horse needs MSM supplementation.

    Rated 5 out of 5 by from Simple yet Effective For my horses in lower level training, MSM by Smartpak provides the appropriate amount of supplementation to maintain healthy joints. This allows my horses to train to their full potential.

    Rated 5 out of 5 by from No more creaks! I started using this on my 2 senior horses about 2 months ago. The gelding is 35 (but didn't really show signs of stiffness) and my 32 y/o QH mare who has a turning radius of the Titanic and creaks when she walks. While still stiff, the QH no longer creaks, seems to have improved her breathing, and her coat has improved from the case of rain-rot that I've been battling. I will definitely continue to use this product.
    Date published: 2011-11-28
    Rated 5 out of 5 by from Love it! Toby was put on MSM after his vet and I noticed some stiffness behind. In about 3 or so weeks I noticed a huge difference. His stride was much smoother and it felt as though it was easier for him to move out. I love MSM! He gobbles his Smartpak right up!
    Date published: 2011-11-20
    Rated 5 out of 5 by from Great Value I started my mare on this because I read that MSM can help with Sweet Itch. I also needed a mild joint supplement to support her-- we've had an easy summer and not been in heavy training, so I didn't feel we needed a whole lot of HA/Chondroitin, etc. She has done WONDERFULLY on this product-- she's not as itchy, her skin is healing, and she's not been stiff once this summer-- even after being on stall rest for 3 days when she hurt her frog. Great value, works as well as the more expensive MSM supplement we WERE purchasing before.
    Date published: 2011-09-29
    Rated 5 out of 5 by from COUGH IS GONE Success at last!! My gelding's cough has finally subsided after a year of vet bills and other treatments that didn't help much. The MSM seemed to do the trick. I wish I had tried it first instead of last.
    Date published: 2011-09-27
    Rated 5 out of 5 by from This product is amazing. Deuce's hips and hocks aren't sore anymore! He was having back problems because of the pain and it is totally gone!
    Date published: 2011-09-06
    Rated 4 out of 5 by from MSM by Smarstpak Eventing puts a lot of wear and tear on my horses joints, so a good joint support is a very important. I have tried several different types of joint supplements but even after having her on these supplements for months I never see a change. So i decided to just try plan MSM. So I went on here to Smartpak and gave there MSM a try. Ever since being on it my horse seems more comfortable! She also loves the taste!!
    Date published: 2011-08-18
    Rated 5 out of 5 by from Great addition for all horses I have my baby (just turned 4) and my big (17.3 1300+ lbs) Oldenburg mare both on this for maintenance with evening. For my peace of mind, its spectacular especially for the price. $9 a month? You can pass on McDonalds a few times for your horse to be more comfortable. Especially with my big mare with all the pounding she does on the joints, anything to help a bit. Only problem has been that she seems to not especially like the taste, so had to mask it with oil, and she's not a usually a picky eater... (quite the opposite)
    Date published: 2011-08-17
    Rated 4 out of 5 by from Good Overall Product This product has a good impact on the overall performance of my horse. Once we added this to his SmartPaks almost immediately we saw that he began to move more fluidly and had a much easier time extending and collecting himself. A good add to your SmartPak!
