Executive Summary
Study by Barbara Levine, MD, Cornell University Medical College, et al. published in the October issue of the American Journal of Clinical Nutrition finds that calcium citrate supplementation (1 g per day) did not increase the lithogenicity (measured by urinary calcium oxalate saturation) of 14 women with a history of kidney stones. The researchers warned, however, that the findings do not mean that all calcium supplements will not contribute to the formation of kidney stones because "other calcium salts might not produce the same results" and stones may arise from other dietary factors
