Research has found that patients with a vitamin D deficiency were almost twice as likely to test positive for COVID-19 compared to patients with sufficient levels of vitamin D.
With winter approaching, care home residents spending more time indoors and elderly people being particularly vulnerable to vitamin D deficiency, researchers are advising people take vitamin D supplements to reduce the risk of contracting COVID-19.
Vitamin D is found naturally in foods such as oily fish, red meat, liver and egg yolks, however, it is difficult to get sufficient amounts from food alone.
Vitamin D supplements are widely available at the majority of supermarkets and pharmacies. It is important to not take more than 25 micrograms per day as levels that are too high can be harmful.
