Great product. Fast delivery

Super easy to order and arrived quickly

Hello, I think it is good for my two retired 20 year-old horses. It is part of a combination of good conditions and care like very big boxes, good vitamins and hay and a daily two to ten hours of being outside depending on the season and the weather.

Always have had prompt service.

My appy has been doing great on the msm!!!

Still have not received this.

I hear less snapping and cracking of joints since using the msm

Not sure how absorbable it is

I purchase this for my daughters senior mare, my older gelding and mare. My daughters mare is 21 and when we first got her over a year ago she was stiff in the hind end and a bit underweight. A year later and with the help of MSM from MadBarn she is so much better. Much more supple when she walks, she’s been on numerous trail rides without any soreness afterwards and her attitude is great. We have her on W3 oil and she’s been holding her weight gain well. Great products and I highly recommend!

I ordered MSM to address a "clicking" issue in my 19 yr old mare's left hind leg. Six weeks into introducing this product to her daily diet, I have noticed that the "clicking" has disappeared. Thanks, Mad Barn!
