Bulk Magnesium Oxide?

Where can you purchase MagOx in bulk? I’m in CT and I’ve had no luck with Tractor supply or the local farm and pet. Seems crazy to spend the money for a little bag of a branded supplement (like MVP) that is the same thing. I know I’ve heard people on this board say they’ve purchased in bulk…was it online somewhere?
Thanks!

Ask those places if they can get it. Often they can, but don’t keep it in stock. Tell them it’s a cattle supplement and that might ring a bell for them.

I think you can buy it from HorseTech as a single ingredient in bulk.

Most feed stores will order it if you ask. I had bought a 50 pound bag. Ended up selling it to someone else.
My horse won’t eat powdered anything, he’s just sure I’m trying to poison him.

Just call around the livestock feed stores, someone will have it. Not the “garden center” feed stores (if you know what I mean), but the REAL feed stores. If you can’t buy 100 bales of hay and a uterine bolus for a cow, it’s not a real feed store. They’ll have it-- you might have to drive a bit to get there, but I buy feed grade 50lbs of MgO for like $5 a bag and it lasts me FOREVER, so it’s worth it.

I don’t feed it in bulk, but I am feeding Remission which has Mag in it plus some hoof supplements and other vitamins for a very good price. The 10lb bucket is almost a year’s supply.

I also like this which is just Mag by itself

I use DiMagnesium Malate which is supposed to be better absorbed in equines, but who knows as every source has a different opinion. Anyway, I order it from Amazon: https://www.amazon.com/gp/product/B00BOV8LMI/ref=od_aui_detailpages00?ie=UTF8&th=1

All the different magnesium forms have different concentrations of elemental Mg, and different absorption rates.

Mg Malate is only about 20% Mg. MagOx is 56% Mg. At some point, absorption isn’t as important as the % of Mg in the product. I’ve been tempted to do a spreadsheet with all the forms, to figure out how much of each you’d have to feed to get, say, 10gm of Mg, then find the costs associated with some of the more commercially available products, but have never gotten the energy for it LOL
