With the prospect of a universally effective vaccine in doubt, many of us have turned to diet and lifestyle to “shore up our Covid-19 defenses.” While many of the supplement regimens marketed as cure alls for Covid-19 are lacking scientific validation, natural compounds like vitamin D are showing some promise in serious research settings. What other nutrients can battle Covid-19? Are there pharmaceutical drugs that can be repurposed to assist in treating the coronavirus? Our guest today, Dr. Theoharis Theoharides has some answers. Dr. Theoharides is an MD, and member of the faculty at Tufts Medical School, who also holds a PhD in pharmacology, and a master's in immunology, from Yale. We discuss the latest research on how flavonoids and other natural compounds impact the immune system and why this research matters for our approach to treating Covid-19 in the coming months.
