Quercetin-studies are looking at this potent antioxidant, great for heart and lungs, to see if blocks viruses from entering cells. shown in dozens of studies to have anti-carcinogenic, anti-inflammatory and antiviral activities.
- Promotes cardiovascular health
- Supports antioxidant status
- Quercetin is an AllerTame flavonoid, i.e., one that may promote a healthy immune response to environmental challenges.
What Does Quercetin Do?
According to the Department of Pathology and Diagnostics at the University of Verona in Italy, quercetin glycosides and other flavonoids, are “anti-viral, anti-microbial, anti-inflammatory and anti-allergic agents.”
Recent in vitro studies have demonstrated that quercetin acts as a potent antiviral agent by inhibiting viral replication of several respiratory viruses, including influenza virus, parainfluenza virus, respiratory syncytial virus, adenovirus, and rhinovirus.
In one study, quercetin inhibited influenza A virus replication in the laboratory more effectively than the anti-flu drug Tamiflu®.
For the same reason I take NAC, I take Quercetin. These two nutrients help protect my lungs. And Quercetin is great for allergies. It blocks the allergic response at several points. It suppresses the actions of immune system cells, reducing the amount of the substance called histamine, that accounts for itchy skin, watery eyes, and (more dangerously) loss of blood pressure during serious allergic reactions. Quercetin also impairs the function of certain cell types that lie at the heart of the allergic and autoimmune processes.
Quercetin blunts the allergy-like components of the asthma response. It reduces the number and activation of inflammatory immune system cells, cuts histamine levels, and relaxes airway smooth muscle.
In chronic obstructive pulmonary disease (COPD), chronic inflammation, oxidant stress, and physical damage to the lungs conspire to obstruct airflow. In severe cases, the walls between alveoli (tiny air sacs) break down in the condition known as emphysema, that results in wheezing, labored breathing, and eventually heart disease.
The novel coronavirus is in a family of coronaviruses that includes everything from other SARS viruses that cause serious respiratory problems to the common cold.
Quercetin has been tested against other viruses in the Corona family. A 2004 lab study showed that it blocked the entry of another SARS coronavirus into cells. And a 2012 study concluded the same thing.
A Montreal scientist by the name of Michel Chrétien is studying Quercetin. He recently received a 1 million dollar donation to begin a clinical trial. That study was proceeding in China, but now that the virus is controlled there, it may have to move back to Montreal.
Additional studies are needed, but for now it looks like Quercetin is another supplement to begin taking. My family and I are taking quercetin.
Quercetin is a phenolic antioxidant found in onions, green leafy vegetables and fruits such as apples and cherries. Quercetin supports cardiovascular health via its role in the inhibition of LDL oxidation.* Quercetin is one half of the rutin molecule, another phenolic antioxidant, but it is the more biologically-active antioxidant.*
