Magnesium malate, the magnesium salt of malic acid, is a mineral supplement often used for nutritional concerns. It is represented by the chemical formula C4H4MgO5[1] and has a molecular weight of 156.376 g/mol. Magnesium malate is discussed as being a more bioavailable form of magnesium, along with other forms such as citrate and glycinate.[2]

Dimagnesium malate is another common form of this compound seen in the dietary supplement market, produced by such dimetalhydroxy malate-yielding processes as the one described by a 1997 patent awarded to Albion Minerals.[3] The primary difference in this compound can be seen by its characteristic of having two elemental magnesium molecules, whereas magnesium malate has a single elemental magnesium molecule.
