The BDA backed the UK’s chief medical officer, Sally Davies’ decision to review the issue, after an increase in vitamin D deficiency was shown among at-risk groups. These include women who breastfeed, people not exposed to sufficient sunshine and the over-65s.

The government currently only advises vitamin D supplements for pregnant women and children under 5. But some parents report that they were not aware of this advice.

At-risk groups

Davies will now be contacting health professionals across the UK on the need to prescribe and recommend vitamin D to all at-risk groups.

Jacquie Lowdon, spokeswoman for the BDA Paediatric Group, said: “The BDA welcomes the announcement by the chief medical officer that all health professionals will now be proactively asked to prescribe vitamin D supplements to all at-risk groups. This is a recommendation that dietitians have always supported.

“This is an important public health message which has the potential for significant health benefits. It is strongly supported by the BDA.”

Vitamin D is produced by the body when outside in direct sunlight. It also makes sure the body absorbs enough calcium in bones and teeth, preventing illnesses such as Rickets.
