We all want to stay healthy, and for many that means topping up our vitamin and mineral levels with supplements. Scientist from the University of Copenhagen had long known that low levels of vitamin D was detrimental to health, but their new study looked at what high levels of vitamin D do to the body.
The results shocked them. They found that blood levels of vitamin D above 100 nanomol per litre of blood increased the risk of dying from a stroke or coronary.
“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,” Peter Schwartz states.
“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. (source)
