Vitamin D is amongst very important component for human growth. And changes in blood level of vitamin D should not be good for health. Researchers from University of Copenhagen are the first in the world to show that there is a connection between high levels of vitamin D and cardiovascular deaths.
In terms of public health, a lack of vitamin D has long been a focal point. Several studies have shown that too low levels can prove detrimental to our health. However, new research from the University of Copenhagen reveals, for the first time, that also too high levels of vitamin D in our blood is connected to an increased risk of dying from a stroke or a coronary disorders.
Peter Schwarz, Professor at the Department of Clinical Medicine and his team 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.
They have also analysed their mortality rate over a seven-year period after taking the initial blood sample, and in that time 16,645 patients had died. Furthermore, they have looked at the connection between their deaths and their levels of vitamin D.
the study confirms that there is indeed a correlation between mortality rates and too low levels of vitamin D, but the new thing is that the level of vitamin D can also be too high.
"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. 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", Peter Schwartz states.
That having too much vitamin D in our blood can be bad for our health has never been proven before, and it may have great influence on our future intake of nutritional supplements.
He concluded that these are very important results, because there is such great focus on eating vitamin D. We should use this information to ask ourselves whether or not we should continue to eat vitamins and nutritional supplements as if they were sweets.
As per peter, we shouldn’t simply up the dose to feel better. We should only consume such vitamins in close coordination with our GP.
The results of study were published in the world-renowned Journal of Endocrinology and Metabolism.
