It is a 28-day study and involves participants aged 30 and above.


  • Vitamin D helps boost immunity.
  • Several COVID-19 patients have been diagnosed with Vitamin D deficiency.
  • This new study may help find Vitamin D’s effect on COVID treatment.

Vitamin D has been in the news for months now. A fat-soluble vitamin, vitamin D is one essential nutrient that helps boost immunity and prevents viral infections. Moreover, an adequate dosage of vitamin D may also reduce the risk of heart disease and respiratory troubles – two of the severe effects of COVID-19. An earlier study, published in The Journal of Clinical Endocrinology and Metabolism, found that over 80 percent of people affected with Covid-19 suffer from vitamin D deficiency. Hence, experts around the world recommend loading up on this nutrient for nourishment and immunity.

Adding to this major observation, a new study by researchers at Brigham and Women’s Hospital is all set to find the possible effects of vitamin D on treating COVID-19 infection. Titled ‘Vitamin D for Covid-19 (VIVID)’, it is a clinical trial to evaluate whether vitamin D can reduce the severe symptoms of the virus.

As per the official website of the trial (, the researchers will focus on people aged 30 or older, who have been recently diagnosed with COVID-19. “People who have received a recent positive test result and had onset of their symptoms within the past 5 days may be eligible to join the VIVID study,” a statement on the website read.

The participants in this study are asked to take vitamin D or placebo study capsules every 28 days, provide 2 at-home blood samples (by finger-prick) and complete two brief online questionnaires- one regarding the start of the trial and the other to be filled once a week for 28 days of taking the pills.
