Immune System – Vitamin C and Quercetin

Marik, published paper, Jun 19, 2020.

“Quercetin and Vitamin C: An Experimental, Synergistic Therapy for the Prevention and Treatment of SARS-CoV-2 Related Disease (COVID-19)” in the journal Frontiers in Immunology, which notes:

“Ascorbic acid is a crucial vitamin necessary for the correct functioning of the immune system.  It plays a role in stress response and has shown promising results when administered to the critically ill.  Quercetin is a well-known flavonoid whose antiviral properties have been investigated in numerous studies.

There is evidence that vitamin C and Quercetin co-administration exerts a synergistic antiviral action due to overlapping antiviral and immunomodulatory properties and the capacity of ascorbate to recycle the quercetin, increasing its efficiency.

Safe, cheap interventions which have a sound biological rationale should be prioritized for experimental use in the current context of a global health pandemic.”

Incidentally, ascorbic acid (vitamin C) and the bioflavonoid quercetin (originally labeled vitamin) were both discovered by the same scientist – Nobel prize winner Albert Szent-Gyorgyi.  Quercetin’s antiviral capacity has been attributed to five main mechanisms of action:

1. Inhibiting the virus’ ability to infect cells by transporting zinc across cellular membranes
2. Inhibiting replication of already infected cells
3. Reducing infected cell’s resistance to treatment with antiviral medication
4. Inhibiting platelet aggregation –  and many COVID-19 patients suffer abnormal blood clotting
5. Promoting SIRT2, thereby inhibiting the NLRP3 inflammasome assembly involved with the COVID-19 infection

Thank you Dr. Livingood for this information from his Immune YOU Masterclass.

BTW, I’ve seen other videos of the high dose Vitamin C that works well as a therapy for acute cases of COVID-19 infections –  Intravenously administered by a doctor/naturopath.
