Quercetin VS COV-19

Sep. 05. 2022

Milan, 23 February 2022 – Very important results from a recent human study led by University of Pavia, Italy, and involving 120 high exposure healthcare workers: quercetin supplementation helps maintaining health conditions in 75% people working in a COVID-19 infectious environment.

Such evidences confirm once more the efficacy of quercetin, in being a favourable supplementation in situations where possible exposition to SARS-CoV-2 risks is higher.

It’s important to remind that in the global emergency due to COVID-19 it’s required to follow the guidelines provided by international and local Health Authorities. Social distancing, mask use, consulting the doctor if any symptoms occur are the strict and necessary rules everybody must follow. And only drugs must be used in acute clinical situations.

But at the same time supplementation of specific botanical ingredients, like quercetin, can play a positive role, thanks to its proven capacityto modulate the body physiological response to a possible infection, capacity due to the pleiotropic mechanism including the senolytic action. It’s also worth remembering quercetin’s proven properties to modulate immune and inflammatory responses in individuals experiencing respiratory discomforts.

“Quercetin, for its crucial properties, fulfills the need for a multifactor action that is useful for the potential counterbalance of a possible COVID-19 infection – explains Mariangela Rondanelli, Department of Public Health, Experimental and Forensic Medicine, University of Pavia - Given this background, the aim of the study was to evaluate the potential effect of 3 months’ supplementation with Quercetin (250 mg twice a day) as favourable modulation of body physiological response when symptomatic COVID-19 may occur. In total, 120 subjects were enrolled, with 60 in the supplementation group and 60 in the placebo group. Subjects underwent rapid COVID-19 diagnostic tests every 3 weeks. During our study, 5 subjects had COVID-19, only 1 out of 60 subjects in the quercetin group and 4 out of 60 in the control group. Complete clinical remission was recorded at 7 and 15 days in the supplementation and placebo groups, respectively”.

Another important result of the study is related to the long-term protective potential of quercetin, as further says Mariangela Rondanelli: “Analysis showed that, at 5 months, those who had taken the supplement had a protection factor of 14% more to stay healthy, than that of those who had taken a placebo”.

The study carried out by the University of Pavia adds to those, conducted some months ago, which showed that quercetin supplementation helps people maintaining their health condition in a SARS-CoV-2 infectious environment, without substituting the standard precautionary measures and treatments envisaged by the medical protocols.
