Middle-aged men with high levels of vitamin A in their blood are more likely to break a bone in later years than those with lower levels of the vitamin, report Swedish researchers this week.
The authors point to current food fortification and widespread supplement use as a possible cause of the raised levels of vitamin A.
[...]
The team concluded: “Our findings suggest that current levels of vitamin A supplementation and food fortification in many western countries may need to be reassessed.”
"One may conclude from such data that supplements containing vitamin A should not be routinely used by men or women and that fortification of cereals with vitamin A should be questioned," writes Lips.
