Can we ever get too much vitamin D?
Yes, say researchers. In fact very high intakes of vitamin D could be associated with similar risks as very low levels, say the team behind this study.
Published in the Journal of Clinical Endocrinology and Metabolism , the researchers investigated the association between all-cause mortality and serum levels of vitamin D in almost a quarter of a million people in Denmark.
“We found higher mortality in people with a low level of vitamin D in their blood, but to our surprise, we also found it in people with a high level of vitamin D. We can draw a graph showing that perhaps it is harmful with too little and too much vitamin D," explained Darshana Durup, from the University of Copenhagen – who led the research.
