Vitamin K may help protect against kidney stones

Healthy levels of vitamin K help prevent excess calcium build-up in the blood and along artery walls. Doctors thought chances for developing kidney stones would increase when vitamin K levels are low.

In this study of 1,748 men and women, doctors measured levels of a protein that inhibits calcium buildup—matrix gla protein (MGP). Vitamin K activates MGP. One-third of the participants began the study with high levels of inactive MGP.

Over the 12-year follow-up period, those with the highest levels of inactive MGP were 31 percent more likely to have developed kidney stones than those with lower inactive MGP levels. The findings suggest that increasing vitamin K in the diet or adding vitamin K supplements may help keep kidney stones from forming.
