Quercetin and Vitamin C: FLCCC Protocol for COVID-19

Quercetin is a natural antihistamine and anti-inflammatory plant pigment that boosts your immune system and may work to control viral replication, according to some research. It allows zinc to exert its proven antiviral properties; in treating COVID-19, quercetin may also lower inflammation, help clear mucus, prevent ventilator-induced damage and support immunity.

According to the research, quercetin has been shown to help fight obesity, Type 2 diabetes, circulatory dysfunction, chronic inflammation and mood disorders. It has even been found to help lower blood pressure. Researchers have found that quercetin can trigger tumor regression and begin the process of apoptosis. This is programmed cell death, without which cells can grow uninterrupted and develop into cancerous growths.



Quercetin was initially found to provide broad-spectrum protection against SARS coronavirus in the aftermath of the SARS epidemic that broke out across 26 countries in 2003. Now, some doctors are advocating its use against SARS-CoV-2, in combination with vitamin C, noting that the two have synergistic effects.

Quercetin

Incidentally, ascorbic acid (vitamin C) and the bioflavonoid quercetin (originally labeled vitamin P) were both discovered by the same scientist — Nobel prize winner Albert Szent-Gy├Ârgyi. Quercetin and vitamin C also act as an antiviral drug, effectively inactivating viruses. 

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 cells’ 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 COVID-19 infection
Similarly, vitamin C at extremely high doses also acts as an antiviral drug, effectively inactivating viruses. 

A molecular docking and pharmacological study, published in Heliyon, March 2021; highlighted that flavonoids such as quercetin was demonstrated to efficiently block the human ACE-2 receptor whereas
hesperidin, naringin, and ECGC were found to be efficient towards the viral spike protein.

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 quercetin, increasing its efficacy.

Quercetin and Vitamin C Work Synergistically

June 19, 2020, Dr Marik published the paper “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 quercetin, increasing its efficacy.

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


The paper presents evidence for the use of vitamin C and quercetin — based on their biological actions and pharmacokinetics profiles — both as prophylaxis in high-risk populations, and as an adjunct to drugs such as Remdesivir or convalescent plasma in the treatment of hospitalized COVID-19 patients.

Quercetin Dosage

Quercetin is also part of the FLCCC I-Prevent and I-Care protocols for COVID-19. 

The FLCCC recommends quercetin 250-500 mg daily for prevention (I-Prevent Protocol) and 250 mg twice daily for early treatment (I-Care Protocol). 

Quercetin works best when taken with vitamin C and Bromelain, as vitamin C helps activate it and bromelain helps with the absorption. In this study (PubMed), Bromelain also has anti-viral property against COVID-19 virus and anti-clotting property, and therefore may be useful against COVID-19.

Caution: 
  • Quercetin has one moderate drug interaction with warfarin. Do not take quercetin without medical advice if you are using warfarin.
  • Quercetin should be used with caution in patients with hypothyroidism (low thyroid hormone) and relevant thyroid hormone levels should be monitored.

About FLCCC Alliance

The Front Line COVID-19 Critical Care (FLCCC) Alliance was initially formed as a working group under “emergency” conditions of the early COVID-19 pandemic in response to multiple early reports of COVID patients with an inexplicably high need for prolonged mechanical ventilation and an excessive mortality associated with the prevailing “supportive care only” recommendations disseminated by the majority of national and international health care organizations.

As a group of highly published leaders in critical care with expertise in therapies directed at severe infections, in particular “HAT” therapy first developed by Dr. Paul Marik for the treatment of bacterial sepsis, and along with published high patient survival rates from our centers, we were contacted by equally concerned and motivated colleagues from other specialties.

In October 2020, the FLCCC Alliance identified, based on a review of the recent and rapidly emerging clinical trials evidence, that ivermectin, an anti-parasitic medicine, has highly potent real-world, anti-viral, and anti-inflammatory properties against SARS-CoV-2 and COVID-19. This conclusion is based not only from multiple in-vitro and animal models, but from numerous clinical trials from centers and countries around the world showing repeated, consistent, large magnitude improvements in clinical outcomes when ivermectin is used not only as a prophylactic agent but also in mild, moderate, and even severe disease states. Further, data from large “natural experiments” that appear to have occurred when various regional health ministries and governmental authorities within South American countries initiated “ivermectin distribution” campaigns which then led to temporally associated decreases in case counts and case fatality rates.

Based on these findings, the FLCCC team has developed the I-MASK+ protocol for prophylaxis and at home treatment of early stage disease.

Disclaimer: Always see your doctor before taking these supplements. Be aware that most of the dosages are above the recommended dietary allowance (RDA) and therefore such dosages should not be maintained on a long term basis. 

Our aim here isn't to replace your doctors' advice. It is intended as a sharing of knowledge and information. Do take note that supplements are not 100% protective or curative against COVID-19. 

Although ivermectin and hydroxychloroquine are relatively safe drugs, they are still synthetic chemicals that can have side effects. Vitamin D, C, Zinc and Quercetin are nutrients that your body require for optimal health. Nutrients are safer alternatives especially if your risk is low e.g. age below 50 and no other chronic illness. Discuss with your doctor on the benefit vs risk for each treatment.

Nutritional supplements are meant to tip the scales in favour of you in terms of your immune system and to improve your probability of a smooth recovery, if at all you do get COVID-19. 

You still need to follow the advice given by CDC, WHO and your local authority in terms of local guidelines such as mask wearing, vaccination, social distancing and avoiding crowds. If you combine multiple strategies, it's going to be difficult for the virus to spread and survive.
