therapeutic dosage of calcium carbonate ?
Limestone gets its name from the Latin word "calx" which means lime. Limestone is primarily composed of the mineral calcite, which is a form of calcium carbonate. The name reflects the mineral composition and the fact that it often contains high amounts of lime.
calcium came from a rock. +++ Yes, that's its source for plants and animals, but as a solution in water of limestone's & chalk's principle constituent, calcium carbonate. Further back it derives from hydrolysis (a form of dissolution in water) of the calcium-silica compounds existing as minerals making up the igneous rock, granite. Thus released into the seas it can re-enter the complicated "rock cycle" by being taken up in the formation of limestone & chalk. Ultimately, like every other chemical element on this planet and around the Universe, calcium is created by nuclear fusion in giant stars whose eventual death has the energy to initiate these reactions, and then to blow them out into Space in Supernovae bursts.
