Vitamin D and COVID-19

An increasing number of studies highlight the critical role of vitamin D not only in maintaining bone health but also in supporting and enhancing the immune system’s defense mechanisms. As reported in The Lancet in July 2020 by Dr. Fiona Mitchell, the UK Department of Health recommended that all elderly individuals receive vitamin D supplementation during the COVID-19 pandemic. This recommendation was based on findings suggesting that vitamin D deficiency may be associated with an increased risk of adverse outcomes in the event of SARS-CoV-2 infection.
