Works wonders!
I have a 5yo ottb who has always been hot and a very forward ride. We tried a few calming supplements and none really worked. My picky eater doesn’t have any issues eating it and it has helped his demeanor tremendously and he will stay on it for the foreseeable future.

Seems palatable
Horse ate it ok. Unsure if it helped or not. Could have been just seasonal change.

These work great for my colt! I can't miss a day or he'll be crazy without it! Recently recommended to a friend for her horse and notice a change already!

My horses refuse to eat it
I really liked the idea of pelleted Magnesium, and at first, both of my horses seemed to like it well enough. Within a week, though, both have begun refusing any bucket of feed/supplement that includes this product. No surprise for my picky gelding, but even my mare, who is generally happy to eat whatever she's offered, turns up her nose at this stuff. Yesterday I tried offering both horses each element of their respective buckets separately, and this is the thing they object to. I can't comment on the efficacy of the supplement itself -- I assume it's perfectly fine if the horses actually swallow it.

Glad I found this!
After researching all of the supplements, I found that most are lacking in magnesium. This was the best brand with the best price.

Good Product - Strong Smell
I had my horse on Ultra Calm SmartPaks for a couple years. He's matured a lot & is 8 now so I took him off them and thought I would try the MVP Magnesium 5000 as a replacement...a much lower dose of magnesium. After using them for a couple days I noticed that he wouldn't touch his grain. We tried a couple things to get him to eat it but nothing worked. They have a rather strong smell so I'm guessing that's why he refused it.
He's been very calm out on the trails so maybe he doesn't need a calming supplement now. I called your outstanding customer service dept. and they gave me a refund credit which I greatly appreciate. I'll continue to be a SmartPak customer in the future. Thank you!

Great
Bought this for my TB with kidney problems who can't have much sugar in his diet. Has helped keep his magnesium levels good, and have definitely noticed a change in how much better he feels. He loves the taste as well! The only problem is I bought the 10 pound bag and found the bag's quality not to be great, had to move the supplement to a container.
