Alice,

Dolomite is a balanced source of calcium and magnesium. Why is it not commonly offered as a nutritional supplement?

Dear Just wondering,

Dolomite is an extract from limestone and marble. Since it may contain the toxic elements mercury and lead, dolomite is not a recommended source for calcium and magnesium — other forms of these minerals are available that would be safer to take. See Calcium and Iron Maiden for more info about calcium supplements.
