Great product for custom supplements! Doesn't cling or blow away like the powder form.

Love this. Clean simple product. I believe making my horse feel more calm. No problem eating it in his feed.

Love the product and the Mad Barn completely. I started my gelding on Magnesium Oxide because he's levels was making him very nervous and just a flight risk to ride. He had taken 4 bags worth of Magnesium Oxide, I seen a bit of change but not really as much as I was looking for. However, I will definitely be ordering again because I do think he did get some benefit from your Magnesium Oxide some. And the price compared to others OMG, hands down great folks, great product and amazing prices.

I’m impressed, I really do see good results, it definitely helps neutralize behavior.

Amazing. Did not change horses personality. But total drop in anxiety. Will reorder for ever

Great product at a great price!

Has not arrived

horse is eating it well!

High quality, palatable, no odor, excellent cost to quality ratio

I was looking for a cheaper option to the Heiro supplement for IR horses to save me money. The Magnesium Oxide is the cheaper option and has worked for me, so I dropped the Heiro.
