    MSM is rated 4.7 out of 5 by 279.
    Rated 5 out of 5 by from Affordable Joint Care! I have been using this supplement for about one year. I have a 16 year old Appaloosa gelding who was a rescue. I have decided to use him for barrel racing, and I wanted to give him something basic to keep his joints healthy. Overall, he is a very healthy horse, so I did not feel that I needed to put him on an extensive joint supplement--just something basic to help him ease into work and keep any swelling or discomfort away. He has done very well on this! Sometimes he does not eat all of the powder, but it eventually gets cleaned up in his feed tub. Pellets would be nice, but I do like how economical this particular supplement is. I couldn't be happier with the results!

    Rated 5 out of 5 by from Great product product arrived in good condition and upon opening there were no visible lumps or clumping that you sometimes see in other MSM brands.

    Rated 5 out of 5 by from Noticeable Results I started my older, retired endurance horses on this at my vets suggestion. I saw noticeable improvement in their comfort levels and the elasticity of their gaits after the first week on the recommended doseage. Even my farrier commented on how much better they felt to him in terms of their flexibility as he worked on them. I was sold! This is a great product at a great price!!!

    Rated 5 out of 5 by from A Staple for all of my Horses! I lost my 25 year old Quarterhorse to EPM. The Vet never told me or the Farm owner (this is a new business for them) that all Horses in the area are exposed to EPM. I know what it is because it is like Multiple Sclerosis in Humans. Had I known my Horse was exposed I would have managed him differently. Now my surviving Horses all get this MSM every day to help keep Inflammation in check.

    Rated 3 out of 5 by from Just OK For Me I tried this brand of MSM out for the first time recently. While it's good, when I got the package home and read the ingredients, it appeared that this MSM is only half strength to the Animed brand we normally buy, which SmartPak does not carry. The consistency was a bit different (not necessarily negative), but overall, we were not thrilled with the product. I then repurchased the Animed. They had their loading doses, then with the Animed, they only need it 1x/day vs. 2x/day with this brand. OK product but we'll stick with what we've got.

    Rated 5 out of 5 by from Hard to say after a month Hard to say after a month and my horse doesn't currently have joint issues in just trying to prevent them or delay them after she jumped a fence as a 2 year old clipping her knee on the post all the way to the bone. She's 10 now and thankfully has not had any lameness issues. Good thing is that she eats it and she doesn't eat many of the "picky eater approved" supplements!

    Rated 4 out of 5 by from I bought this to try on my horse since she tends to get very body sore. I have had good luck with this product on horses in the past. Unfortunately it does not seem to be giving much benefit to my horse. I would still highly recommend this product to people. For the price, I feel like it is a very worthwhile product to at least try for one's horse.

    Rated 5 out of 5 by from Great price I am a very loyal MSM user, and have fed it for years. I love this product because of price(especially since I get free shipping through SP!) and its ease of use.

    Rated 5 out of 5 by from Love the quality! I've bought this before and will continue to buy! I feed a supplement that has a little MSM in it but not as much as I'd like, so I supplement with this product. All my horses have eating it since day one. Great value for a great product!

    Rated 5 out of 5 by from Great! I just needed a little something extra for my older dressage gelding in addition to hock injections & polyglycan. Not as creaky or stiff and super cheap!
    Date published: 2015-01-01
    Rated 4 out of 5 by from Amount not as stated Bought this because of good reputation to hold me over until after Equine Affaire when I purchase for the year. The bag contains about 30 servings, not 46. I let smart pak know and they are looking into it. I called select the best directly, they investigated and agreed there was a problem. They promptly sent me another bag to hold me over free of charge, and are addressing the incorrect serving problem with their quality control/production people. The product is good, but until they can correct the problem going forward, you are getting 30 servings, not 46.
