I’ve been using MSM for my 23-year-old mare, Daisy Chain, who has mild joint pain, for the past two years. A few months ago, I switched to the Mad Barn brand. It’s a good product—easy to measure, mix into her feed, and palatable for her. Since starting MSM, Daisy has shown noticeable improvement in her comfort and mobility. The Mad Barn MSM aligns with their reputation for high-quality supplements, and I appreciate the affordability and convenience of their products. I would recommend Mad Barn MSM to anyone looking to support their horse’s joint health!

I love mad barn’s MSM, it really seems to help my horse’s joints and ligaments!

Seems to be helping my dear old gelding get around the pasture this winter. He’s looking perky!

This product seems to be working well for our horses

I am very happy with this product. My horse stretches more easily and what little stiffness he had seems to have been alleviated. Plus, it is very palatable - which is good, because he is quite a picky eater.

Appears to be helping my sore ottb so far! 🤞

Was super easy to order. Shipped very quickly and arrived within a week of it being shipped!

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.

Started trying it over the summer on some of our senior horses and saw a great improvement in their mood and movement. It is a daily for our arthritic and younger horses to help maintain their joint health.

i can’t really say anything about it because the mare i use it for has a few medical conditions right now so results are unsure but im sure it works great
