Large trial to clarify role of vitamin D

The D-Health study, led by Associate Professor Rachel Neale of the QIMR Berghofer Medical Research Centre in Queensland, will follow 25,000 Australians aged 60—79 over five years.

“Vitamin D testing has become a huge trend. This country spends $150 million a year on vitamin D testing despite the fact that testing is unreliable and we don’t even really know what blood level to aim for,” Professor Neale said.

That vitamin D is important for bone health is accepted, but it is not known what level is needed, she added.
