14 Jun 2019 --- Over a quarter of adults aged over 50 are deficient in vitamin D, according to researchers from Trinity College Dublin. Over half (57 percent) had inadequate serum vitamin D levels, of which 26 percent were classed as vitamin D deficient. The research demonstrates that vitamin D deficiency is prevalent in older adult populations living at Northern latitudes and highlights the importance of public health strategies throughout midlife and older age to achieve optimal vitamin D status. The researchers emphasize low supplement use in these regions and call for food fortification and other strategies to be considered at policy level for older populations.
