Quercetin in the Prevention of Covid-19 Infection

Quercetin is a flavonol, a subclass of flavonoid compounds. Of the flavonol molecules, quercetin is the most abundant in fruit and vegetables. Quercetin flavonol is characterized by 3 crucial properties: antioxidant, anti-inflammatory and immunomodulatory. The combination of these 3 properties makes quercetin an excellent candidate for dealing with situations in which oxidative stress, inflammation and the immune system are involved. The purpose of the study is to evaluate the effectiveness of an oral nutritional supplement based on quercetin in the prevention of Covid-19 infection.
