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.
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.
