Quercetin and Zinc: FLCCC I-MASK+ Protocol for COVID-19
The Front Line COVID-19 Critical Care (FLCCC) Alliance was initially formed as a working group during the early COVID-19 pandemic days in response to multiple early reports of COVID patients with an inexplicably high need for prolonged mechanical ventilation and an excessive death rate. Based on rapidly emerging clinical trials evidence, the FLCCC team has developed the I-MASK+ protocol for prophylaxis and at home treatment of early stage COVID-19. Quercetin, zinc and a number of nutrients and drugs are part of this protocol, not only for critical care but also for prophylaxis and mild disease being treated at home. This article, we will dive deeper to provide the scientific background, related references and rationale of the FLCCC protocol.
This is a highly dynamic topic; therefore, we will be updating this article as new information emerges.
Quercetin and COVID-19
As of April 2022, there have been 8 published studies (7 RCTs) of quercetin (c19quercetin.com).
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.
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-Györgyi. Quercetin’s antiviral capacity has been attributed to five main mechanisms of action:
- Inhibiting the virus’ ability to infect cells by transporting zinc across cellular membranes
- Inhibiting replication of already infected cells
- Reducing infected cells’ resistance to treatment with antiviral medication
- Inhibiting platelet aggregation — and many COVID-19 patients suffer abnormal blood clotting
- 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.
June 19, 2020, 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.
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.
FLCCC (Front Line COVID-19 Critical Care) Protocol
The initial MATH+ protocol was released in April 2020. In early July and August, it was updated to include quercetin and a number of optional nutrients and drugs, not only for critical care but also for prophylaxis and mild disease being treated at home.
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, zinc, vitamin D, C and Melatonin and part of the latest FLCCC I-MASK+ protocol. For updated prevention and early outpatient protocol (COVID-19 positive), please check out FLCCC I-MASK+ protocol.
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.

- treatment (therapeutic) dosages are normally higher than the RDA dosages and
- 'maintenance' or 'preventive' dosages that are based on the recommended daily value.
You should ideally supplement your micro-nutrients from healthy and wholesome foods, fruits and vegetables.
Disclaimer: Always see your doctor before taking these supplements. Be aware that most of the 'treatment' 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.
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, social distancing and avoiding crowds. It's better to combine multiple strategies in order to defend yourself against this virus.
