We all want to stay healthy, and for many that means topping up our vitamin and mineral levels with supplements. Scientists from the University of Copenhagen have long known that low levels of vitamin D is detrimental to health, but their 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 nano mol 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 a 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 between 50 and 100 nanomol per litre, and our study indicates that 70 is the most preferable level…
These are very important results, because there is such great focus on eating vitamin D. We should use this information to ask ourselves if 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,” . (source)
This is the first time that having an excess of vitamin D in the blood has been linked to ill health.
Getting adequate vitamin D is vital to prevent diseases such as rickets, which is making a comeback at the moment. Not getting enough exposure to sunlight is more often the cause than a lack of vitamin D in the diet. Women, particularly those whose culture dictates that they cover all exposed flesh are particularly prone to the condition.
Vitamin D also allows the body to utilise calcium more efficiently and a deficiency can lead to weakened structure of the teeth and bones. This makes people far more susceptible to minor injuries causing fractures and to tooth infections causing general malaise.
