02 Dec 2020 --- An analysis of 300,000 UK users of the ZOE COVID Symptom Study App found that supplementation of probiotics, omega 3 fatty acids, multivitamins or vitamin D was associated with a lower risk of self-reported SARS-CoV-2 infection. These findings stem from the largest observational study on COVID-19 and dietary supplement use to date, collected from over 1.4 million app users from the US, the UK and Sweden.
