Longevity Briefs: Healthy vitamin D levels could reduce COVID-19 infection severity

Posted on 30 September 2020

Longevity briefs provides a short summary of a novel research, medicine, or technology that caught the attention of our researchers in Oxford, due to its potential to improve our health, wellbeing, and longevity.

Why is this research important: COVID-19 has recently taken its one millionth victim, and with a second wave becoming increasingly apparent across Europe, and many other parts of the world, the search for something to alleviate the impact of the virus is crucial. It has been suggested that vitamin D has a protective effect against COVID-19.

What did the researchers do: To investigate this a research team based at the Tehran University of medical sciences, Iran, collected and analysed hospital data from 235 patients infected with COVID-19.

Key takeaway(s) from this research: They found that 74% of the participants had severe COVID-19 infection and 67.8% were deficient in vitamin D. After adjusting for confounders, the data showed a significant relationship between Vitamin D deficiency and clinical severity of COVID-19 infection. Based on this the researchers suggest that maintaining sufficient levels of vitamin D in the general population, and even more so in hospitalised patients, is critically important in reducing morbidity and mortality associated with COVID-19.
