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!

All my horses are on the magnesium supplement and they love it, i see a difference. Yes I recommend it to everyone who has horses.

Helped my horse relax.

A good number of our horses leave the magnesium in their feed buckets
