Overall happy with this MSM. The package I received had a tear in the bag so lost some product which was disappointing. Likely a one off case so would purchase again in the future.

Excellent service

My horse has been on high dose vitamin E for a few years. His blood is checked regularly to confirm the dosage. Before Mad Barn vitamin E was available I was using Elevate E which is a great product but very expensive. Mad Barn vitamin E is equal to or better and is less expensive, especially when having to feed high doses. Love it!

Super happy to have found a quality magnesium supplement at a very reasonable price! Fast and free delivery too!

I use these electrolytes when the temperature soar to 40C and my horses are sweating just standing around in the shade. No hesitation from all three senior horses when adding to their soaked hay cubes.

Everything that you do all the I information you provide makes me love your company.

Love the magnesium oxide! My new nervous gelding has calmed right down and has been able to finally enjoy his new home.

I was recommended to Mad Barn by my trimmer, who felt that my horses' hoof and overall health will benefit. It was easy to navigate the website, but I needed help to decide which product was the best for us. Communications were quick and knowledgeable. My order arrived in a few days and I started feeding it right away. The horses LOVE the taste of it. One of mine has been somewhat picky with his daily meal lately because I am adding some medicine to it. Now, he's digging in and eating as heartily as ever! I look forward to seeing what the impacts will be on their overall health in the months to come.

Shipping is free and I got my product very quickly!!! Service is incredible and answer questions quickly. Very helpful company!

Have only been feeding for a short time. But my two oldies are showing more of their previous personalities already. I will monitor over time.
