A new study by King’s College, in collaboration with Guy’s and St Thomas’s NHS Foundation Trust and the University of South Australia, has found a connection between low levels of vitamin D and a higher risk of being hospitalized due to Covid. The research aimed to determine if vitamin D levels could impact the likelihood of contracting Covid and the severity of the illness in those infected.
The study, published in PLOS One, discovered that individuals with insufficient vitamin D levels in their blood were more prone to hospitalization with COVID-19, although low vitamin D levels did not increase the chances of initial virus exposure. These findings align with existing research indicating that adequate vitamin D levels may reduce the severity of diseases like Covid. The analysis involved health data from over 150,000 participants of the UK Biobank.
Professor Sophia Karagiannis, a co-author of the study and Professor of Translational Cancer Immunology and Immunotherapy at King’s College London, emphasized the significance of vitamin D in supporting a healthy immune system to combat infections. She highlighted the need for further research in larger and diverse populations globally to expand on these findings.
The professor suggested exploring ways to boost vitamin D levels, such as through dietary adjustments, supplementation, and controlled sun exposure, to potentially mitigate severe effects of Covid-19 infection. While vitamin D supplements are available for purchase, experts caution that it remains uncertain whether these supplements alone can alleviate the severity of Covid. More research is necessary to ascertain if enhancing vitamin D status could offer protection against serious Covid outcomes.
