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 harmful and is connected to an increased risk of dying from a stroke or heart disease.
The level of vitamin D in our blood should neither be too high nor to low. Scientists from the 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.
“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”, states Peter Schwartz, Professor at the Department of Clinical Medicine and physician at Glostrup Hospital.
“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. You shouldn’t simply up the dose to feel better. We should only consume such vitamins in close coordination with our GP”, Peter Schwartz concludes.
