Wonderful magnesium product!
I have a gelding that can be a little reactive on windy days or when riding in the indoor. He is a picky eater so other magnesium products have been difficult to feed so I switched to the Magnesium 5000 and he eats every pellet! He is more focused during training and along with proper work and a foraged base diet, his topline has never looked better. I recommended magnesium to all horses in training. They get support for recovery from the harder rides and overall seem more restful in their stalls.

A More Relaxed Ride
: I have a fairly spooky mare, so these are a staple in the barn to have. While she already gets a more comprehensive calming supplement that includes some magnesium, I like to give these to provide additional magnesium. While these can be given daily, I give these to my mare during harder workloads, stressful events, new environments, etc. I really like that these are simple, affordable, and easy to feed pellets. My mare will even eat these if given separately. Strongly suggest to any horse needing that additional Magnesium.

Helps!
I have used this supplement (mostly)on and (occasionally) off for a few years now with my OTTB gelding and I do notice a difference in him when I stop adding it to his feed.

DOES NOT WORK
Does not work, he’s been on this 3 months now. And he is actually getting more jumpier.. and I just missed the deadline of changing back to his original supplement and will now have 28 days of supplements I won’t use.

Great results
We added Magnesium to our Smartpak on the advice from our vet.
He seems calmer and less tense during work and would highly
recommend this product.

Stressed mare calm again
My mare started having problems with stress when we went to rodeos and horse shows. This really helped her and she's much happier and calm. She's calmed down during riding and has been used in lessons for children! Loves the flavor and gets mad when I forget to put it in her food. Will most likely give her this for the rest of her life to help her calm down and rest.

Great changes in young TB
This has made a huge difference for my rambunctious young TB, his naughty baby behavior is pretty much non-existent since I started this supplement. I was skeptical a supplement could make such a difference but I am sold! I have him on 2 scoops a day, will try to wean to 1 soon and see if it is enough..
