Excellent quality!Our 9yr old ottb has been on your MSM and Omneity for 8 months and is showing a remarkable difference in movement, coat, hoof, and overall health. Would love to incorporate an HLA supplement into his routine.

Just switched over to Mad Barn supplements. So far so good. Saving money and my horses are eating them. Using MSM for joints.

5 stars

It was free with a purchase, I passed it on to someone else at the stables

My horse won’t eat this powder. If I add it to his AT+ and Visceral he won’t eat those either so everything gets wasted.

I swear my arthritic 19-year-old QH gelding is doing so much better since he’s getting Mad Barn MSM. I rarely see a limp in him anymore!

love it the packaging and the product

Love this MSM !!! All my horses are doing amazing on it

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
