These horses will do best if also fed a low glycemic diet (one low in simple carbs; see accompanying box), but the supplementation of Mg will be beneficial even if the low glycemic diet is not fed. As well as being important for the function of nerve and muscle, Mg is involved in the formation of Hydroxyapatite, one of the principle components of bone and a major "hardener" of bone.

In addition, this trace mineral is known to support healthy cardiac function and calming in horses. In addition, a normal body Mg content is necessary for the maintenance of electrolyte balance, particularly for Calcium (Ca++) and Potassium (K+). Cells that are deficient in Mg show impaired CHO metabolism and a reduced insulin response. The main pathway for the deposition of Mg is via the kidneys. The GI tract absorbs what it needs and the rest is dumped. Cushing’s disease, more properly termed pituitary pars intermedia dysfunction (PPID), is a neurodegenerative disorder that leads to the enlargement of a portion of the pituitary gland in the brain of the horse which results in excess production of certain peptides and hormones that have a direct effect on the adrenal glands.
