A recent study published in the journal BMJ Nutrition Prevention & Health, claims that consuming multivitamins, omega-3, probiotics or vitamin D supplements may reduce the risk of testing positive for SARS-CoV-2, at least among women. Contrary, vitamin C, zinc, or garlic supplements were not shown to be associated with a lower risk of testing positive for the virus, in the study.

This study utilized information supplied by 372,720 UK individuals who were taking dietary supplements and found that probiotics, omega-3 fatty acids, multivitamins or vitamin D were associated with a lower risk of SARS-CoV-2 infection: by 14%, 12%, 13% and 9%, respectively, mainly among women of all ages and weights. 

This study comes as a large clinical trial to inform evidence-based therapeutic recommendations.
