A cohort study published by the American Journal of Public Health suggests that there is no significant risk of kidney stones with Vitamin D supplementation. In fact, only 13 cases of kidney stones were reported in the cohort of 2012 subjects whose serum levels of vitamin D ranged between 20 ng/ml and 100ng/ml and who were followed for a median of 19 months. However, the study did report that males, older people, and people with a high BMI had a greater risk for kidney stones, regardless of vitamin D levels. These results would render patients supplementing with vitamin D for protection against multiple diseases less concerned about kidney problems, according to the authors. Have any of your patients taking Vitamin D reported concerns related to kidney stones?
