"Calcium supplements are intended to be consumed with a meal, and when taken as directed, the two forms of calcium are absorbed at roughly the same rate. However, when taken on an empty stomach, the body has a much easier time absorbing calcium in its citrate form vs. its carbonate form..."

As an example, calcium carbonate is 40 percent elemental calcium, so 1,250 milligrams (mg) of calcium carbonate contains 500 mg of elemental calcium. Be sure to note the serving size (number of tablets) when determining how much calcium is in one serving..."
"Calcium citrate is absorbed equally well when taken with or without food and is a form recommended for individuals with low stomach acid (more common in people over 50 or taking acid blockers), inflammatory bowel disease or absorption disorders."
