Magnesium citrate (3:2) (3 magnesium atoms per 2 citrate molecules), also called trimagnesium dicitrate, trimagnesium citrate, or the ambiguous name magnesium citrate . The substance may come as anhydrous or hydrated salt with varying properties.
The anhydrous salt has good solubility in water (~10% or more at 25 °C) and contains 16.2% elemental magnesium by weight. Its taste is slightly bitter-alkaline.
The hydrated salt may have 3 to 14 molecules of water attached to it and has much lower solubility in water (2% or less at 25 °C). [1] This form doesn't have any noticeable taste.
Commercially available are the anhydrous salt, as well as nonahydrate (with 9 molecules of water attached) and 14-hydrate. [2] The nonahydrate form contains 12% elemental magnesium by weight.
