Calcium supplements appear to increase the risk of kidney stones (American Journal of Clinical Nutrition, Jul. 2011). Some people make more kidney-stone forming oxalate after large doses (2,000 mg) of vitamin C (Journal of Nutrition, Jul. 2005).
Excess amounts: Too much calcium over a prolonged period can cause constipation, kidney stones and poor kidney function. It may also interfere with the absorption of other minerals, such as iron and zinc. Excess amounts are only consumed via supplements.
