Powdered Magnesium Oxide for Equine
Horse magnedium. White powdery. Very fine substance. I prefer to use the more granular magnesium.

Easy to use.
I have an older thoroughbred who's on the extra spicy side of her ancestry even though she's retired from all forms of competition and only does light riding so finding a supplement that helps calm her down and she will eat is a must have. I like that this product is Organic and family owned. My first thought of this Magnesium supplement was that it was rather expensive. However once I received it I see that it uses Magnesium Glycinate rather than Magnesium Oxide, which is what most supplements use and is a very cheap and not readily absorbed type of Magnesium. Magnesium Glycinate is also less likely to cause diarrhea After several weeks of adding this to her evening bucket I've seen a marked improvement in her excitability and have seen a much calmer horse. I'll definitely be buying this again.

Horse won’t eat it in dry food. Only mush
This has a strong lemon lime scent to it. If I put it in dry feed my horse won’t touch it. If I put it in mush he will eat it

Might work, or it might not....?
I got this for a 24 year old Paso Fino mare who competes in both endurance and NATRC. She's highly sensitive, probably has PPID/Cushings and extremely hard heat cycles. However, she will NOT eat it and will go on a hunger strike for up to 2 days after I add this to her feed. I tried a full scoop for a few days and she stopped eating, leaving most of her grain. I waited a few days after removing it from her diet, and once she was back to eating, I attempted to split the serving in half. Once again, back to a hunger strike. She has been on a different company's magnesium oxide with zero issues, so she -will- eat grain with MagOx. I gave up trying to give to my mare and opted to see if my 16 year old Rocky Mountain gelding would eat it (he is slightly less sensitive, but is starting to exhibit some symptoms of PPID/Cushings), and he devours it with zero issues. So, unfortunately I'm unsure if this would have resolve the issues with my mare as I cannot get her to try it, and my gelding doesn't have the same issues.

Good magnesium
I have had my equines on magnesium of various brands/types over the years. It seems to help with so many things. This is favorably comparable, and seems easier to eat than straight mag. Even my picky eater will eat a quarter-scoop of this (he usually turns up his nose at any supplements, so a quarter-scoop is a win for him). Seems like a quality supplement!

Acceptance in a time of stress
I am currently using this supplement for my mini. With the recent change to a dry lot, I have felt that she has been stressed. She loves her grass and her pasture so to be forced to go to a new area I think has been a stressful on her. This supplement has been easy to add to her ration balancer feed. I do think it’s helping her to accept and be more calm in her new space. It’s a very simple supplement to add that appears to have no flavor or one that even my picky eater doesn’t mind.

It's expensive but it's worse if the horse won't eat it
We've got a retired 27 year old world champion quarter horse. we still compete him locally because he enjoys it and he's so well trained that my 72 year old wife, and both our granddaughters, can compete, and win, in various classes by just sitting in the saddle. We don't know how much longer he'll be around but we'll do whatever it takes for him to enjoy the rest of his life. Magnesium is good for hoof health, arthritis, bones, sleep, anxiety, and numerous other things. As long as it doesn't make him lethargic we'll keep using it. In other words he really doesn't need to calm down and he doesn't have any anxiety. He deserves and lives the life of a king. We've tried other magnesium supplements. Some he would eat and some he wouldn't. Old horses get more and more difficult to keep weight on. They can be picky eaters. Dillon isn't really picky but he sometimes doesn't have much of an appetite. It's really important that supplements don't discourage him from eating. This magnesium supplement is very palatable. I tasted it before giving it to him. It's not bad. I won't say it taste great but I wouldn't say alfalfa taste great either. He seems to like it and that's the important thing. Is it beneficial to him? We've had him on it for a couple of weeks so it's too early to tell anything definitive but the point of most supplements is preventative. Some benefits you can readily see. Things like calming, energy, sleeping, even the effect on pain or stiffness, but things like bone health aren't so obvious. At this point we're pleased with this supplement even though it costs more than most others we'll continue to feed it. We just started a four year old on it. He can use a little calming. I'm considering taking it myself as a test of the effect it has on arthritis.
