What are the risks of calcium supplements?

ANSWER

At normal doses, calcium supplements may have side effects such as bloating, gas, and constipation. Very high doses of calcium can cause kidney stones. Research has found an increased risk of heart attacks and strokes in some people taking calcium supplements in addition to a diet high in calcium, though the true accuracy of these findings is being actively debated by experts.
