Recent research shows that taking probiotics may reduce the risk of COVID-19 infection and the onset of symptoms in unvaccinated people.
The study, conducted by Duke University and published in Clinical Nutrition in December 2023, included 182 participants. All of them had been in contact with family members who had contracted COVID-19, but the participants had not exhibited symptoms themselves, and none had received the COVID-19 vaccine. The researchers randomly divided participants into two groups, one taking probiotics and the other taking a placebo (control group) for 28 days.
