Be careful: This vitamin can result in cardiovascular death

In public health, vitamin D has long been a focal point. Some studies have shown that very low levels can prove harmful to our health.

However, the new study by Copenhagen University reveals, for the first time, that even the very high levels of vitamin D in our blood are linked to an increase in risk of death from stroke or coronary death.

The results have just been published in the popular Journal of Endocrinology and Metabolism”.

We've studied vitamin D levels in 247,574 Danish, and so far this is the world's greatest basis for this type of study. We have also analyzed their mortality rate over a seven - year period following the initial blood sample, and 16,645 patients were then dead. Furthermore, we have looked at the connection between their death and their vitamin D levels,” explains professor at the Clinical Medicine Department, Peter Schwarz.

The bottom line is clear: the study confirms that there really is a correlation between mortality rates and very low levels of vitamin D, but what's new is that vitamin D levels can also be very high.

If your vitamin D level is below 50 or over 100 nanool per litre, there is a greater link to death.

And when the numbers are over 100, there seems to be an increasing risk of death from stroke or coronary death. In other words, vitamin D levels should not be too low but not too high. Levels must be somewhere between 50 and 100 nanool per litre, and our study shows 70 is the most popular level,” said Peter Schwartz.

That the excess level of vitamin D in our blood may be bad for our health has never been witnessed before, and that could have a profound impact on our future receiving food supplements.

These results are very important because there is a huge focus on the consumption of vitamin D.

We should use this information to ask ourselves whether or not we should continue to consume vitamins and food supplements as if they were cookies. We should not simply raise the dose to feel better. We just have to consume such vitamins in close coordination with our doctor”, concludes Peter Schwartz.
