Research just published in the Journal of Endocrinology and Metabolism shows that mortality is greater not only for those who are Vitamin D deficient, but that an excessive level of vitamin D is also associated with increased mortality.
Lack of vitamin D and its association with a number of health problems has been the focus of a lot of research in the past few years. This newly reported research from the University of Copenhagen reminds us that more is not necessarily better when it comes to vitamin D.
Peter Schwarz, Professor at the Dept. of Clinical Medicine stated,”We have studied the level of vitamin D in 247,574 Danes, and so far, it constitutes the world’s largest basis for this type of study. We have also analyzed their mortality rate over a seven-year period after taking the initial blood sample, and in that time 16,645 patients had died. If your vitamin D level is below 50 or over 100 nanomol per litre, there is an greater connection to deaths. 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. In other words, levels of vitamin D should not be too low, but neither should they be too high. Levels should be somewhere in between 50 and 100 nanomol per litre, and our study indicates that 70 is the most preferable level.”.
That having too much vitamin D in our blood can be bad for our health has never been proven before, and it should have an important impact on the manner by which individuals take Vitamin D supplements. People should coordinate their taking of vitamin D with a medical check up including a blood test, to hit the sweet spot of a Vitamin D level of at least 50 nmol/L but not much higher than 70 nmol/L.
