I've purchased your MSM several times, the last two bags I received had a very strong, unpleasant smell.

Have been giving MSM to my horses, dogs, and I have taken it myself. It has been very effective for all of us. Thank you for this product. However, your shipping charge of $15 is more than half of the price of the product, and that is really frustrating. So I might order more often if shipping was more reasonable

Love this powder, only complaint is I wish the enclosed scoop was a full dose for a 1000lb horse. Having to scoop out three times takes much longer when trying to efficiently feed multiple horse or preportion supplements ahead of time for barn workers.

Mad barn has been great to deal with so far. The msm was a much better deal than my usual supplier.

High quality and can't beat this price!

I noticed the change in my horse within a couple of days and was able to get her off of prescription pain medication. Thank you for making a pure uncomplicated product.

Great product for horses.

Great Stuff! So good foe hoses.

Using this for my nearly 30 year old mare. It really helps her age related stiffness, especially in winter.

MSM in combination with Omneity have made such a huge difference in my OTTB, her coat and hooves are healthy and she seems to be moving and feeling better.
