One prime example would be quercetin, which is a naturally occurring zinc ionophore.24 As reported by the Green Stars Project,25 “Researchers from Oak Ridge National Lab used the world’s most powerful supercomputer, SUMMIT, to look for small molecules that might inhibit the COVID-19 spike protein from interacting with human cells and, interestingly, quercetin is fifth on that list.”26

Quercetin is one of only three natural products found to inhibit the SARS-CoV-2 spike protein. The only natural product found to be slightly more effective is luteolin, a polyphenol found in radicchio, green peppers, serrano and green hot chili peppers, chicory, celery and many other foods.27

Quercetin is another flavonols compound found in a variety of foods, including apples, Brassica vegetables, capers, onions, tea and tomatoes, just to name a few. It’s also contained in medicinal products such as Ginko biloba, St. John’s Wort (Hypericum perforatum) and elderberry (Sambucus canadensis).

Research has already demonstrated that quercetin is a powerful immune booster and broad-spectrum antiviral. As noted in a 2016 study28 in the journal Nutrients, quercetin’s mechanisms of action include the inhibition of lipopolysaccharide (LPS)-induced tumor necrosis factor α (TNF-α) production in macrophages.
