Thinking about vitamin D with Andrew Grey and Tom Chatfield - a podcast by The BMJ

Interest in vitamin D, and it’s association with a range of health outcomes continues - at least if the regular flurry of papers on the subject that are submitted to The BMJ are anything to go by, and with Covid-19, interest has piqued again.

GPs are regularly asked to prescribe it, and to test for deficiencies. Low levels of vitamin D are associated with a large number of health outcomes, but, given the high costs and low accuracy of tests, would it be easier just to recommend taking supplements without testing vitamin levels first, taking a “won’t hurt but might help” approach? If so, should we all be taking them, and would doing so help to prevent against COVID-19?Our guests:

Andrew Grey is an endocrinologist and an associate professor of Medicine at the University of Auckland.

Tom Chatfield is a philosopher, author and broadcaster, whose work looks at humans and technology, as well as cognitive biases.
