Does quercetin take the sting out of covid?
A few days ago we wrote about a sponsored Italian-Pakistani study, in which supplementation with an easily absorbable form of quercetin accelerated the recovery of subjects with covid. The same researchers published another human study in which quercetin reduces the risk of complications from an infection with SARS-Cov2. And yes, that study was also paid for by a manufacturer.
The researchers experimented in Pakistan with 152 people who were infected with SARS-Cov2, as the corona virus is officially called. The subjects were not so ill that they had to be hospitalized when the study started. They stayed at home and were given painkillers and anti-inflammatories.
Half of the subjects took a supplement containing 500 milligrams of quercetin phytosome twice a day for 30 days. In total, the subjects received 1000 milligrams of quercetin phytosome per day.

One minus point less
A minus of the study we discussed last time was that the subjects in the quercetin group were 6 years younger than the subjects in the control group. This was not the case with the study we are now talking about.
The research we are writing about today, like the study last time, was conducted and funded by the creators and manufacturers of the proven form of quercetin. The patent for that quercetin variant is in the name of the sponsor, the Italian Indena. [WO2019016146A1]
In the control group, 29 percent of the test subjects eventually ended up in hospital, in the quercetin group this was 9 percent. In the control group, hospital stay lasted an average of 3 days, in the quercetin group 1.7 days. These differences between the groups were statistically significant.
In the control group, 20 percent of the subjects needed oxygen. In the experimental group this was 1 percent.
In the control group, 11 percent ended up in the ICU. In the experimental group, no one went to the ICU.
Finally, 3 subjects in the control group died. In the experimental group, no one died.
Supplementing with quercetin-type molecules could [...] be considered a promising strategy for the treatment of viral respiratory infections", write the researchers.
