Where are you getting the information that
horses are over supplemented with magnesium? Mostly our earth is deplete in it
now from with the exception of some of the desert country (AZ comes to mind).
I can tell you it’s difficult to get
a good diagnosis as to the amount you need to dose. I’m in the PNW
(lots of rain) and there is virtually none in the ground here, so none in my
horse’s feed. I’m using a supplement that I feel comfortable has
enough for my horses (SportHorse Grass Supplement from www.uckele.com), so I’m not
supplementing anymore just plain MagOx. But, when I was it was approx 1 scant
tablespoon to balance the other feed/pasture that my horses were getting.
The sensitivity you’re talking about
does sometimes come with Magnesium deficiency. But, I’m sure there are
other things that could cause it.
I’d suggest calling your county
extension office (if your horse is on forage) and ask them about the content
of Magnesium. Then, get a good analysis on your hay if that is a big portion
of your horse’s feed. Then, you can look at that vs what you’re
supplementing and get a good nutritionalist to help you balance it all.

My trainer thinks my horse might be magnesium deficient and
wants to supplement her with a high dose of it...I don't know enough about this
to feel comfortable with doing this...Everything I have read is that horses are
much more likely to be oversupplemented than under...It is my understanding
that there are serious consequences to the horse if you overdose with Mg...My
horses all have free choice accees to TM and get grass hay in the winter
(grazing in the summer)...I feed Nutrena Triumph 10 when they are being worked
and supplement with 4Plex EQ by Zinpro Corp...This horse has not been working
the last two months- she has been grazing and getting fat...The trainer cites
her nervousness and hypersensitivity as reasons for her being deficient...
Can someone please give me an idea of what I would see in my
horse if she were indeed deficient with Mg. I don't feel like shelling out a
wad of cash to have serum/urine testing done just based on someone's
hunch...and I don't want to megadose with anything unless I know for sure that
the horse needs it. My thoughts are that the horse should be fine in the
mineral/vitamin department- I have not seen any muscle tremors/ or uncontrolled
twitching, but the horse is VERY sensitive to touch- and always has been-which
I have always attributed to her being a hot, endurance racing bred
horse...Thanks Susan
BTW the wither information was extremely helpful- and I plan
on having a saddle fitting done with one of those Putty pads...
