    MSM Pellets by SmartPak is rated 4.7 out of 5 by 361.
    Rated 5 out of 5 by from Love MSM This has definitely kept my sensitive skinned chestnut mare from breaking out because of bugs and allergens. She was coming inside with hives all the time and after a month on this, not more lumps and bumps!

    Rated 4 out of 5 by from Very palateable I started my young horse on this just because I feel like I should do something for his joints and MSM one of the few supplements to have scientific proof that it does anything. I haven't seen any changes but since I am using this for preventative purposes, that doesn't bother me. It's cheap and I feel like I'm at least not hurting; he's happy to have something extra to eat in his breakfast, so we're both happy.

    Rated 5 out of 5 by from My Mares magic gold I started my mare on this a month ago and she went from 17 to 7 years old. She acts like she is young again. She moves and runs more freely then she ever have before.

    Rated 5 out of 5 by from Go to Supplement MSM has proven itself to me. I was wondering today how long the great progress that my horse has made would have taken without using this supplement. I am also very happy with the weight and muscle that he has put on during this layup. The plan is to see if we can get him going again in a couple of weeks. I think it would have taken quite a bit longer without SmartPak.

    Rated 5 out of 5 by from This has helped my horse so much So I thought I would write a follow review about Smart MSM, my OTTB Finn has been getting this for now 4 years he is now 11 years old, with no joint problems at all. I love the pellets and I know that Finn eats all of it, in fact he will eat right out of my hand like a treat. Smart MSM has help Finn feel amazing his hooves are strong and his coat looks great it is a great supplement.

    Rated 5 out of 5 by from Haven't used it very long but... I have only been using MSM for about 40 days but if my mare's increased energy is any indication of it working then A+. She isn't hot but you can definitely tell she feels good enough to really move.

    Rated 5 out of 5 by from Great for the value! I have used this for two months, it is good product for the amount spent. However I did changed to another product for next month in my smart pak that has glucosimine in it as well however this product is WAY cheaper!

    Rated 5 out of 5 by from Super easy to feed I own a tank of a mare who has never come out stiff. However, being a hunter/jumper on a fairly rigorous work schedule (5-6 days a week), I wanted to put her on a joint supplement for preventative maintenance. I first tried the powdered version of the Smartpak MSM, because my mare isn't a very picky eater, but I found she left most of the powder behind when eating since it sank to the bottom of the tub. I finally moved to the pellet form and I'm in love! My mare will eat it with or without grain. As an added bonus, the vet said the MSM helped my mare overcome a mild respiratory infection by controlling inflammation.

    Rated 5 out of 5 by from Quality product Have always loved SmartPak. Have been using their products for years. Started my 18yo Dutch on the SmartPak MSM about 2 months ago and I noticed a difference in his comfort level within a couple of weeks. Highly recommend!

    Rated 5 out of 5 by from Won't Go A Day Without It! I have a 19-year-old ASB mare who has done it all (Saddleseat, Hunt, jumps, trails, therapeutic riding programs...) and is still in great shape. This is the only supplement she's on and she's been on it for about 3 years now. I won't go a day without it. She's never been arthritic or lame, but I like all horses to be on a joint supplement of some kind in order to keep them sound. My mare can separate a powder from anything (even applesauce ....quite impressive, really) so this pelleted formula is definitely a time saver and I know she's getting all of it.

    Rated 5 out of 5 by from Helps with allergic pruritis. My mule is allergic to gnat bites, we have been using smart bug off and now added MSM and he is much more comfortable, no longer scratching his neck and ears.

    Rated 5 out of 5 by from Outstanding results My mare was limping at a trot, Only at a trot, it was so strange! Had the chiro out, the vet out, and there was no reason for her being lame! I started her on MSM smartpak pellets on the day I received it, and it has been 5 days and she is no longer limping/lame on the front. She took off running and bucking when I turned her out this morning. Did some round pen work at trot and she is a different horse. I am amazed at how fast this worked for her. Will be using it on my retired reiner also.

    Rated 5 out of 5 by from Helping my aging horse with allergies. I started adding this supplement to the SmartBreathe smartpak I get for my 18 yo mare with IAD. She manages well on the SmartBreathe, but the extra MSM has made the difference between occasional coughs and no coughs, especially in the spring when she suffers more acutely from airway inflammation. In addition, she's moving more freely and seems more supple under saddle.
