||P.235 left column: "Aging represents a major risk factor for magnesium (Mg) deficit. Several alterations of Mg status have been identified in the elderly [refs 1-13]. Total body Mg content tends to decrease with age, with bone being the main storage compartment of body Mg. Of the 21-28 g of Mg present in the adult human body, about 55-65% is in the mineral phase in the skeleton, 34-44% in the intracellular space, and only 1% in the extracellular fluid [primary source]."
