Too Much Vitamin D Poses Risk


A study done at the University of Copenhagen is the first in the world to show a connection between high levels of vitamin D in the blood and cardiovascular deaths. Higher levels of the vitamin were associated with an increased risk of dying from a stroke or a coronary.

“If your vitamin D level is below 50 or over 100 nanomol per litre, there is a greater connection to death,” says Peter Schwartz, professor at the Department of Clinical Medicine at the university. “We have looked at what caused the death of patients, and when numbers are above 100, it appears that there is an increased risk of dying from a stroke or a coronary. Levels should be somewhere in between 50 and 100 nanomol per litre, and our study indicates that 70 is the most preferable level.”

 A lack of vitamin D long has been a concern from a public health standpoint. Several studies have shown that low levels of vitamin D can have detrimental health effects. This most recent study shows that it is a critical to find a balance.


 The results recently were published in the Journal of Endocrinology and Metabolism.
