06 Sep 2017 --- Researchers from Trinity College Dublin have discovered that one in eight adults over the age of 50 living in Ireland is vitamin D deficient. According to the research, this increases to one in four over winter, and 5 percent of adults over 50 are even vitamin D deficient during summer. The study has implications for people living in sunlight-starved countries across the globe and has led to calls for public health policy to consider supplementation.
