A preferred calcium compound/citric acid molar ratio in the composition of matter of the present invention is between about 0.6 and about 1.5. In a most preferred embodiment, the composition of matter of the present invention consists essentially of calcium hydroxide and citric acid having a calcium compound/citric acid or calcium hydroxide/citric acid molar ratio of about 1.25. The composition of matter of the present invention has a utility demostrated by dissolution in water to form a liquid dietary calcium supplement comprising soluble calcium citrate. This composition of matter may comprise one or more of a flavorant, lubricant, sweetener or colorant usable to maintain a powdery texture or to enhance the flavor of a beverage prepared therefrom.
