I started using MSM a couple of years ago to help with my mare's arthritic hocks. The last order was full of firm lumps, where previously the product was lump free. A little more of a nuisance to mix it in the feed. Otherwise I have no concerns.

“I chose Madbarn!” -Pepsi All of our horses are on MadBarn supplements. We love the Omenity, Visceral +, Spirulina, Magnesium …. Basically everything. We absolutely stand by this brand 100%. We rescued this mare from a bad situation; When she came to us, she was a rack of ribs. We tried everything to help her gain weight (including putting her on free choice hay) - the only thing that truly worked was putting her on beetpulp with spirulina, Visceral + and magnesium! I believe these products aided in saving her life. Thank you Madbarn for keeping all of our horses happy and healthy!
