How much MSM is too much?
I started giving my mare pure MSM about 3 weeks ago because she's been cracking/creaking/clicking when she walks. She was supposed to get 2 scoops daily for a week as the loading dose. Now it's been 3 weeks, and she's still been getting 2 scoops a day. I don't think having 2 scoops a day for the extra 2 weeks will kill her, but should I continue? The only reason I ask is because just within this last week I haven't noticed any creaking/cracking noises when she walks. I don't want to cut her back on her supplement and have her cracking again, but I don't want the supplement to do more harm than good if I give her too much.
