Recent headlines have claimed that a supplement of vitamin D may help protect against the coronavirus – but is there any truth to the reports?
Vitamin D is famous for helping to keep our bones healthy. But it’s vitamin D’s impact on immunity that is grabbing the headlines. The report came from the Irish-run TILDA study which looks at the health of older people in Ireland. This study found that older people who were deficient in vitamin D were more likely to have respiratory infections compared with people who had good levels of vitamin D.
Vitamin D deficiency is common in Ireland, mainly due to our ongoing lack of sunshine. We should make vitamin D when the sun shines on our skin – but lack of sun means we can struggle make all the vitamin D we need. Although we can get some vitamin D from food, it is difficult to get the full amount. It is even more difficult for older people to have healthy levels. As we get older, it is harder for our bodies to turn sunlight into vitamin D. The TILDA study found that 27% of people aged over 70 were deficient in vitamin D and this jumped to 47% of people aged over 85.
