Worked on my OTTB
I bought this for my OTTB who is very anxious. When I ride her, it usually takes a good 15 min of prancing around or straight to a canter to calm her down and then we actually start working and riding with a purpose . But sheâs been on this every day for a little over a month and her attitude has calmed down tremendously, itâs like Iâm on a different horse . Love love love. Our feeder at the barn said it even calmed her down in her pasture at feed time , no more being pushy and bucking around while getting her grain .

Actually works!
Been using this for 6 months for our young gelding and recently ran out. I wasnât sure if he still âneededâ it, but he really does seem more fussy and tense these last two weeks without it. So I am contributing his change due to not having this as part of his daily feed. IâmNot exactly sure the magic behind it, but itâs affordable and works. Will be repurchasing for the third time!

Definitely helps
Have a horse with some nerve issues, put him on it, within 3 weeks started seeing a huge difference. Have purchased it twice now and will definitely continue. Makes for a happier horse. The bag is very large , closes easy enough, scoop makes for easy measuring. Product last for a good while, for the price, it’s just right.

Works!
My always over reactive colt (gelding) 4.5 yr old was always a hard to catch guy in the pasture would walk away from me ALL the time even with treats, grain etc. I decided to add Magnesium to his diet and Day 1 he walked right up to me int he pasture i thought okay this is a fluke? since being on it it has not changed he walks up to me follows me around completely different horse in way of being so over reactive with most everything. i can even walk up to him and fly spray him now in the pasture without him walking off. I decided to put my rescue mare on it since she get anxiety when haltered up. she also comes right to me now but she is new here and i wasnt sure of her personality anyway.

Your nervous horse
If you have a horse that is antsy while working, this is the product for you. It is not a Tranquilizer. The effect is very subtle, but a nervous horse that is antsy will walk and focus on the task at hand. I have used this for multiple breeds Horse and Pony, and will continue using it as needed.
