Zinc, an essential trace element, is known for its vital roles in various physiological processes, including immune function. One of the most intriguing aspects of zinc is its antiviral properties, which have been extensively studied and documented.

How Zinc Works

• Zinc interferes with the replication of various viruses in the cell. This action has been observed in viruses such as Flu, rhinoviruses, hepatitis C virus, and coronaviruses, including SARS-CoV-2, the virus responsible for COVID-19.

• Zinc ions directly interact with viral particles, destabilizing their structures. This has been observed in studies where zinc ions were found to reduce the infectivity of some viruses by altering their protein structures.

Zinc and Cell Entry: The Role of Quercetin

While zinc is effective in antiviral defense, its ability to enter cells is crucial for its function. This is where quercetin, a plant flavonoid, plays a significant role.

Quercetin acts as a zinc ionophore, which means it facilitates the transport of zinc ions across cell membranes. 

Vitamin C

Vitamin C helps the immune system combat viruses by enhancing the production and function of white blood cells, boosting the skin’s defense system, and acting as an antioxidant. This vitamin supports the immune response and reduces inflammation, which aids in preventing and managing viral infections.

Vitamin D

Vitamin D enhances the immune system’s ability to fight viruses by promoting the production of antimicrobial peptides and modulating immune responses. It helps reduce inflammation and supports the function of immune cells, such as T cells and macrophages, improving the body’s defense against infections.
