“Quercetin, a naturally occurring dietary flavonoid, is well known to ameliorate chronic diseases and aging processes in humans, and its antiviral properties have been investigated in numerous studies.” (SagePub)
Quercetin aids the absorption of Zinc into cells
We have already learnt how Quercetin and Vitamin C work together to improve each other’s absorption into the body. Well, it has a similar synergistic relationship with zinc too. Quercetin is known as a “zinc ionophore”, which means it enhances the absorption of zinc into the body’s cells. In simple terms, it “holds the door open” for the zinc to enter into our cells. (Journal of Agricultural and Food Chemistry)
Quercetin enhances the absorption of zinc, and both have anti-viral functions. Zinc is a positively charged ion, so it has difficulty passing through the fat soluble cell membrane. This means zinc needs a “transporter” (ionophore) to help it to cross the cell membrane. Many fat-soluble nutrients can do this, but quercetin is a particularly effective, and may also enhance the antiviral properties of zinc. Please read our information about Zinc to learn more about the crucial role it plays in the human immune system, particularly in fighting off viruses.
