Magnesium Oxide (MgO) is a scientifically proven quality source of magnesium supplementation for horses – very high 57% magnesium
This is a premium grade of magnesium oxide with a high level of magnesium and very low level of iron. For this reason, the price of this premium MgO may be higher than elsewhere. Buyer beware, MgO varies in quality. Balanced Equine only sells premium quality.

Magnesium along with calcium and phosphorus are known as the major minerals. Copper, zinc, iron, manganese, selenium and iodine are trace minerals. In a horse’s nutrient intake, either magnesium can be at too low a level compared to the NRC (National Research Council) daily recommendations AND/OR the calcium to magnesium ratio can be too high. Whichever one applies, the diet won’t be optimal.
The symptoms of a magnesium deficiency are the same as for excessive ionised calcium compared to magnesium. Symptoms include muscular symptoms from twitching to spasm, irritability, hypersensitivity, with a potential for intestinal symptoms and heart irregularity when severe. In more extreme cases, a horse can have gait disturbances, including stilted gait, base wide gait behind, difficulty controlling the hind end when turning and reluctance or inability to canter.
Magnesium has many different jobs to do in the body and one of the most important jobs is to control the movement of calcium along calcium channels in cells. The movement of calcium through calcium channels forms the basis for all ‘excitable’ tissue activity, including the nervous system, heart, skeletal muscle and smooth muscle in the intestinal tract, uterus, urinary tract and blood vessels. Magnesium controls the sensitivity of the calcium channel, and is also required for the production and storage of the energy packets (ATP) that is needed by the sodium-potassium pumps to do their job of clearing the calcium from the cell and put it back into storage sites.
Recommended feeding rate is 10 to 20 grams per day.
This is about 1 metric tablespoon depending on how packed (density) the MgO is in the spoon.
Balanced Equine does not recommend excessive supplementation of magnesium in horses – more is not better. Some excess magnesium is excreted but levels in the kidney and bone will rise. Excess may lead to depressed calcium and phosphorus uptake, intestinal, renal and heart issues. Never supplement sufficient magnesium to cause a horse to have diarrhoea.
MgO is a nutritional supplement product for inclusion in horse’s feed. Product has no therapeutic effect and is designed to be administered in a feed for voluntary ingestion for horses.
Animal consumption only.
