Vitamin D - and possibly vitamins K and A - might help combat Covid-19, suggests a new study from the University of Bristol.
The research indicates that these dietary supplements and compounds could bind to the viral spike protein and so might reduce SARS-CoV-2 infectivity. In contrast, cholesterol may increase infectivity, which could explain why having high cholesterol is considered a risk factor for serious disease, the study noted.
'The findings help explain how some vitamins may play a more direct role in combatting Covid than their conventional support of the human immune system,' explained a researcher.
The study has been published in the journal of the German Chemical Society Angewandte Chemie.
