No, calcium citrate is not of higher quality than calcium carbonate. It is, however, the preferred calcium source for the small number of individuals who have no stomach acid (achlorhydria). The majority of people have a normal pH and for them, calcium carbonate has been proven to have a superior absorption rate than calcium citrate. Calcium carbonate also has twice as much elemental calcium by weight as calcium citrate. The term ‘elemental’ calcium refers to the available calcium in a supplement. For example, calcium carbonate has 40% elemental calcium so 1,250 mg of calcium carbonate provides 500 mg elemental calcium.
