Calls to include vitamin D as part of a national strategy to tackle COVID continues to gain momentum as health experts have pushed Ireland’s government to consider and act upon the latest evidence. In an online meeting of the Joint Health Committee this week, Dr Daniel McCartney highlighted a lack of official action in the face of research suggesting a protective role of vitamin D against COVID-19. “Despite the now dozens of positive studies including tens of thousands of participants, there has been no policy change in Ireland to advance what we believe to be an extremely low risk, readily implemented, cheap and potentially highly effective intervention to mitigate this public health crisis,” he said.
