Study finds vitamin D does not contribute to kidney stones

Increased vitamin D levels may prevent a wide range of diseases, according to recent studies. However, some previous studies led to a concern that vitamin D supplementation could increase an individual's risk of developing kidney stones.

However, a study of 2,012 participants - published in the American Journal of Public Health - found no statistically relevant association between 25-hydroxyvitamin D (25 (OH)D) serum level in the range of 20 to 100 ng/mL and the incidence of kidney stones.

This study - led by Cedric F.
