Children whose mothers took extra vitamin D during pregnancy continue to have stronger bones at age seven, according to new research led by the University of Southampton and University Hospital Southampton (UHS).
Bone density scans revealed that children born to mothers who were given vitamin D supplements during pregnancy have greater bone mineral density in mid-childhood. Their bones contain more calcium and other minerals, making them stronger and less likely to break.
