Vitamin D Levels Not Linked to Kidney Stone

A recent study of more than 2000 participants who were followed for a median of 19 months found no statistically significant association between vitamin D levels in the blood and incidence of kidney stones. Body mass index was significantly associated with kidney stone risk. Only 13 participants developed kidney stones during the study: eight had 25-hydroxyvitamin D serum levels below 50 ng/mL and five had levels equal to or above 50 ng/mL. The findings are published in the American Journal of Public Health.
