“If I have kidney stones, should I take vitamin D?” A recent study looked directly at this question in “stone formers,” who are people with a history of repetitive kidney stones. Dr. David Leaf of Columbia University Medical Center and a group of colleagues from Boston to Portland conducted this study on stone formers, who were also vitamin D deficient. If vitamin D causes kidney stones (a common belief), then how exactly do you treat vitamin D deficient stone formers?
