It works great.

Quick delivery, very economical, works great! My sensitive mare was struggling with muscle spasms causing her to swing/flip her head and neck anytime she became uncomfortable. Body work alone was not helping. Speaking with my vet and looking at her diet, we decided to start her on magnesium. This has significantly improved her physical and mental comfort after 4-5 weeks of daily use. I will be keeping her on this as long as I have her! The price point is amazing, and it’s nice to have a product available that isn’t mixed with ingredients that have questionable utility (which also drives the price up). This is my first of many Mad Barn purchases. Thanks!!!

Love this company and its customer service! However, unfortunately, 3 of my horses won’t eat the magnesium. After chatting with them they were more than happy to help me find a solution. Only reason for 3 stars was because my horses didn’t find it palatable.

I like the fact that this person took the time, effort, expensive & research to come up with/particular products the horse can absorb ! Also affordable for the middleman!

Great product, easy to add to feed and horses eat it without issue!

My horse had an MG deficiency. Fed this for 6 weeks, re-check bloodwork, all normal.

I have been feeding my mare this for about 2 years. It has made a world of difference in her— she is much quieter and less agitated (charging, biting) with her pasture mates. She is very focused and consistent when riding too, before she was tense and would often buck when asked to move out. I never run out of this for her! Thank you for such a great and affordable product!

Absolutely IN LOVE with this product! My little specials have decided that the end of the ring is not harboring 😈 demons! The ride ability is much better!

This is by far the best powder magnesium on the market! The best potency and price.

Awesome product and awesome price!
