Kidney Stone Risk Associated With Long-Term Vitamin D And Calcium Intake

Another "benefit" to the cure du jour.

A new study presented at The Endocrine Society's 94th Annual Meeting in Houston reveals that calcium and vitamin D supplements are linked to high levels of calcium in the blood and urine, which could raise the risk of developing kidney stones.

Lead investigator, J. Christopher Gallagher, M.D., professor and director of the Bone Metabolism Unit at Creighton University Medical Center in Omaha, NE said:

"The use of calcium and vitamin D supplementation may not be as benign as previously thought. Pending further information, people should not exceed the guidelines suggested by the Institute of Medicine, which are 800 international units of vitamin D, and 800-1,200 milligrams per day of calcium."

Oops.
