The Council for Responsible Nutrition (CRN) Foundation, via its Vitamin D & Me! education initiative, has applauded new research conducted since the onset of the COVID-19 pandemic that demonstrates significant links between vitamin D and COVID-19. Multiple analyses have revealed that higher blood levels of vitamin D appear to be correlated with lower incidence or severity of COVID-19 in most but not all reviews of the research.
Thirteen recent meta-analyses, generated from more than 100 clinical trials published since the onset of the pandemic, have examined vitamin D and COVID-19. Most of the meta-analyses examined blood levels of vitamin D and COVID-19 while two exclusively examined vitamin D consumption in relationship to the illness. Meta-analyses are statistical reviews of data from multiple independent studies that address highly similar and succinct research questions to observe overall effects.
Most of the reviews found higher blood levels of vitamin D appear to be correlated with lower incidence of COVID-19. Several, but not all meta-analyses found greater severity of and mortality from COVID-19 were associated with lower vitamin D levels. One meta-analysis found reduced mortality with vitamin D intervention following COVID-19 diagnosis, while a smaller meta-analysis did not see a statistically significant relationship. Timing and dosage of the interventions may have played a role in the differing results. Summaries of these meta-analyses and links to the research are available on the Vitamin D & Me! website.
“This growing body of research does not indicate that vitamin D is a substitute for vaccines, mask wearing, social distancing or other behaviors to mitigate the spread of the coronavirus,”said Luke Huber, ND, MBA, vice president of scientific and regulatory affairs at CRN, “but the data does suggest that vitamin D levels may play a role, in combination with other therapies, in strengthening the immune system to resist the virus.”
According to CRN, Vitamin D & Me! provides a space for consumers to explore the collective research on this topic, to educate themselves on the emerging data and to hear directly from the researchers involved. It shares research, expert video interviews, news and education in a user-friendly format, with a particular focus on U.S. consumers ages 55+. The initiative has tracked and reported the latest research on the link between vitamin D and COVID-19 since May 2021 and has already attracted over 160,000 users to learn more about the science connecting vitamin D and COVID-19.
