Magnesium oxide. Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium (see also oxide). It has an empirical formula of MgO and consists of a lattice of Mg2+ ions and O2â ions held together by ionic bonding.
Magnesium oxide is a common compound in the earthâs crust, comprising 35% of its content by mass. However, it has been found in medical studies to have one of the lowest degrees of bioavailability, as low as 4% bioavailable in one study.
