Taking a multivitamin, omega-3, probiotics, or vitamin D supplement can reduce the chances of testing positive for Covid-19. A study published in the journal BMJ Nutrition Prevention & Health reports that the risk is lowered the most among women. It should be noted, however, that supplementation with vitamin C, zinc, or garlic was not associated with the study outcome.
Since the start of the pandemic, public figures and content creators have popularized the use of nutritional supplements to prevent and treat disease.

In the UK alone, market share increased 19.5% at the start of last year, with sales of vitamin C growing 110%, while multi-activity sales increased to 93%. Just as sales of zinc supplements increased by 415% in the first week of March 2020 in the US.
While nutritional supplements may help maintain a healthy immune system, competent health authorities have not confirmed whether this is linked to a reduced risk of contracting Covid-19.

To see if multivitamins, omega-3s, probiotics and vitamin D supplements help prevent the Coronavirus, researchers analyzed the information provided by 372,720 adults in the United Kingdom in May, June and July 2020.
Between May and July, 175,652 people took the supplements regularly, while 197,068 did not. About 67% of women and more than half of them are overweight. In total, 23,521 people had tested positive for Covid-29 and 349,199 had tested negative between May and July.
Therefore, medications have been associated with a reduced risk of infection. After accounting for influencing factors, such as basic conditions and regular diet, no effects were observed among those taking vitamin C, zinc, or garlic supplements.
Professor Sumantra Rai, Executive Director of the NNEdPro Global Center for Nutrition and Health, co-author of the joint journal, commented: “To date, there is little convincing evidence that taking nutritional supplements has any therapeutic value other than maintaining the body’s normal immune response.” .
