Quercetin and Zinc: Zelenko Treatment Protocol (October 2021)

Dr. Zelenko’s main hypothesis based on the data showing that early intervention and treatment of high-risk patients with COVID-19 results in significantly few hospitalizations and deaths. This treatment regimen involving zinc, low-dose hydroxychloroquine, and azithromycin is also apparently known as, “The Zelenko Protocol.”

zelenko protocol

Update: Recently, Ivermectin has come to the fore as a more effective (also long standing, cheap, generic drug), in all three stages of COVID-19. Dr Zelenko has also updated his protocols to incorporate ivermectin as an option for both the prophylactic and treatment protocols as shown below. COVID-19 is a highly dynamic topic. Please refer to the latest FLCCC protocol.

Quercetin

Quercetin and Zinc

The Zelenko Covid-19 Protocols was developed by Dr Vladimir Zelenko. The protocol has as its centerpiece, but not exclusive piece, the combined use of Hydroxychloroquine (HCQ) and Zinc as a means by which a person can both help to prevent or mitigate the contraction of COVID-19, or can actually treat the disease once it has been diagnosed. 

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.

Foods high in quercetin include onions, kale, tomatoes, broccoli, asparagus, berries, red wine, citrus fruits, cherries, and tea. 

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 helps zinc by acting as a zinc ionophore (PubMed 2014), the same mechanism of action that hydroxychloroquine has via helping zinc pass the cell wall where it might halt viral replication.

This zinc ionophore activity of quercetin facilitates the transport of zinc across the cell membrane. It is known that zinc will slow down the replication of coronavirus through inhibition of enzyme RNA polymerase (PubMed 2010). 

The COVID-19 is an RNA (RiboNucleicAcid) virus and requires the RNA polymerase to replicate. Do take note that the study publication was a 2010 publication and is referring to a different coronavirus as compared to the latest coronavirus (COVID-19); though both are from the same family of coronaviruses.

A word about quercetin: Some physicians are recommending this supplement to reduce viral illnesses because quercetin acts as a zinc ionophore to improve zinc absorption into cells. It is much less potent than HCQ (hydroxychloroquine) as a zinc transporter, and it does not reach high concentrations in lung cells that HCQ does. Quercetin may help reduce risk of viral illness if you are basically healthy. But it is not potent enough to replace HCQ for treatment of COVID once you have symptoms, and it does not adequately get into lung tissue.

That said, if you simply cannot get hydroxychloroquine or ivermectin, quercetin is a viable stand-in. Quercetin works best when taken with vitamin C and Bromelain, as vitamin C helps activate it and bromelain helps with the absorption. 

Update: Recently, Ivermectin has come to the fore as a more effective (also long standing, cheap, generic drug), in all three stages of COVID-19. Dr Zelenko has also updated his protocols to incorporate ivermectin as an option for both the prophylactic and treatment protocols as shown below.

Zelenko Covid-19 Prophylaxis Protocol

Prophylaxis is an action taken to prevent or protect against a specified disease i.e. action taken before getting the infection. Greek in origin, from the word "phylax", meaning "to guard" and "watching." The Zelenko prophylaxis protocols are categorised based on the risk profile of the patients i.e. low, moderate or high risk.
  • Low Risk Patients: Young healthy people do not need prophylaxis against Covid-19. In young and healthy people, this infection causes mild cold-like symptoms. It is advantageous for these patients to be exposed to Covid-19, build up their antibodies and have their immune system clear the virus. This will facilitate the development of herd immunity and help prevent future Covid-19 pandemics. However, if these patients desire prophylaxis against Covid-19, then they should take the protocol noted below.
  • Moderate Risk Patients: Patients from this category are healthy but have high potential viral-load exposure. This group includes medical personnel, caregivers of high-risk patients, people who use public transportation, first responders and other essential personnel who are crucial to the continued functioning of society. These patients should be encouraged to take prophylaxis against Covid-19 in accordance with the protocol noted below.
  • High Risk Patients: Patients are considered high risk if they are over the age of 45, or if they are younger than 45 but they have comorbidities, that is, they have other health conditions that put them at risk. These patients have between a 5 to 10% mortality rate if they are infected with Covid-19. These patients should be strongly encouraged to take prophylaxis against Covid-19 in accordance with the protocol noted below.

Protocol for Low and Moderate Risk Patients

The Zelenko protocol for low to moderate risk patients contains four nutrients that can be easily purchased over-the-counter or online i.e. quercetin, zinc, vitamin C and D3.
If Quercetin is unavailable, then use Epigallocatechin-gallate (EGCG) 400mg 1 time a day

Protocol for High Risk Patients:
  • Hydroxychloroquine (HCQ) 200mg once a day for 5 days, then HCQ 200-400mg one time a week (ScienceDirect) (Find a Doctor)
  • Vitamin D3 5000 IU/day or 50000 IU once a week (Amazon)
  • Vitamin C 1000mg once a day (Amazon)
  • Zinc 25-50mg/day (Amazon) | How much zinc to take with hydroxychloroquine?
OR
  • Ivermectin 0.2 mg/kg — one dose on day 1 and day 3, then take one dose weekly (ivmmeta.com). (Find a Doctor)
  • Vitamin D3 5000 IU/day or 50000 IU once a week (iHerb)
  • Vitamin C 1000mg once a day (iHerb)
  • Quercetin 500mg/day (Amazon) (iHerb)
  • Zinc 25-50mg/day (iHerb)
Z-Stack Supplement: In an effort to make it easier for patients, Dr Zelenko has developed an oral supplement that contains all four: vitamin C, quercetin, vitamin D3 and zinc. It’s called Z-Stack Vitamins

Notes: 
  • 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.
  • The use of HCQ is highly controversial. The best scientific evidence from randomised controlled trials suggests that HCQ has limited/no proven benefit for post exposure prophylaxis, for the early symptomatic phase and in hospitalised patients. Considering, the unique pharmacokinetics of HCQ it is unlikely that HCQ would be of benefit in patients with COVID-19 infection (it takes 5–10 days to achieve adequate plasma and lung concentrations). Finally, it should be recognised that those studies which are widely promoted to support the use of HCQ are methodologically flawed. Source: Page 16 of FLCCC Alliance – COVID-19 Management Protocol (version Aug 6, 2021)
  • How much zinc you should take per day depends on the type and forms of zinc, as each supplement contains a different amount of 'elemental zinc'. The percentage of elemental zinc varies by form. For example, approximately 23% of zinc sulfate consists of elemental zinc; thus, 220 mg of zinc sulfate contains 50 mg of elemental zinc (Ref). Zinc picolinate (20% of elemental zinc), zinc ascorbate (15%), zinc chloride (48%), zinc carbonate (52%), zinc citrate (31%), zinc bisglycinate (25%) (Ref) and zinc gluconate (14%) and zinc oxide (80%) (Ref).

Notes:
  • Precautionary Note: Ivermectin has a number of potentially serious drug-drug interactions. Please check for potential drug interaction at Ivermectin Drug Interactions - Drugs.com. The most important drug interactions occur with cyclosporin, tacrolimus, anti-retroviral drugs, and certain anti-fungal drugs. 
  • Due to the possible drug interaction between quercetin and ivermectin (may increase ivermectin levels), these drugs should not be taken simultaneously (i.e. should be staggered morning and night). 
  • Ivermectin is also lipophilic and therefore, bioavailability is maximised on a full stomach; or best to be taken with meal.
  • Vitamin D3 RDA (Recommended Daily Allowance) is 800–1000 IU/day. The safe upper-dose daily limit is likely < 4000 IU/day. Be aware that most of the 'treatment' dosages for nutrients are above the recommended dietary allowance (RDA) and therefore such dosages should not be maintained on a long term basis. 
  • Vitamin D deficiency has been associated with an increased risk of acquiring COVID-19 and from dying from the disease. Vitamin D supplementation may therefore prove to be an effective and cheap intervention to lessen the impact of this disease, particularly in vulnerable populations, i.e. the elderly and obese. 
  • When Is the Best Time to Take Vitamin D? Morning or Night? It is possible that increasing vitamin D levels during the day may act, in part, as a signal that suppresses melatonin generation (source). Therefore, it's better to take vitamin D (with meal) during the day and melatonin to be taken just before bedtime.
  • It is likely that vitamin C and quercetin have synergistic prophylactic benefit. Quercetin should be used with caution in patients with hypothyroidism and TSH levels should be monitored.
  • Please consult with a qualified doctor and only use human ivermectin. Ivermectin for animals contain excipients (binding and storage compounds such as polyethylene glycol (PEG)) that are known to cause liver failure in high doses. 
 

Early Treatment Prevents 'Long Haul' Side Effects

It's worth noting that when you treat early, your risk of developing long-term side effects, commonly referred to as "long-haulers," is virtually nil. Not a single one of Zelenko's patients who received treatment within the first five days of symptom onset went on to develop long-haul symptoms afterward.

According to Dr Zelenko:
 
"I had patients that were long-haulers, but they came to me after that window, and they were already advanced in the inflammatory process. At that point, the cytokine storm had already taken hold. They had developed blood clots, some of them had pulmonary infarct, or strokes actually.

Others developed ARDS or catastrophic lung damage and pneumonias, and others just are not themselves. I don't know how to describe it, but it ate away part of their souls. They're not the same people. There's depression, there's lack of energy. There's a psychological impact as well.

So, it's not that I don't deal with long-haulers, I do. But the way to prevent the long-hauler syndrome is to intervene within the first five days, with appropriate antiviral medication in high-risk patients. That is 100% successful."
 

About Dr Vladimir Zelenko

He graduated with a B.A. degree with high honors in Chemistry from Hofstra University. After receiving an academic scholarship to attend S.U.N.Y. at Buffalo School of Medicine, he earned his M.D. degree in May 2000. Dr. Zelenko completed his family medicine residency at South Nassau Communities Hospital in Oceanside, N.Y. in May 2004. Since then, Dr. Zelenko has practiced family medicine in New York’s Hudson Valley. He has been described by his patients as like a family member to thousands of families, and is a medical adviser to the volunteer ambulance corps in Kiryas Joel, New York.

When asked about studies that seemed to discredit the efficacy of HCQ in treating the Chinese coronavirus, Zelenko explained “You don’t fire a gun without a bullet in it and then say the gun doesn’t work when you don’t kill the target. The studies that were done on HCQ did not include the use of Zinc.  HCQ is what opens the cell and enables Zinc to attack the virus. One is not effective without the other, or without a suitable substitute for HCQ. The studies were designed to fail.”

Dr. Zelenko says that both prophylaxis measures and actual case treatments need to be customized to the individual. As a general rule, he says, those people who are in the higher risk groups, both by age and by other pre-existing conditions, require more aggressive actions on both the preventative and diagnostic side.

“This virus remains relatively stable inside the host for about the first five days,” Zelenko says. “After that it starts to multiply rapidly. It also starts to migrate from sinus to lungs and cardio areas where involvement becomes more severe and treatment becomes more difficult. The key is early intervention.” Zelenko again mentioned his 84% success rate in high-risk patients.

June 1, 2021: The Drug that Obliterates 97% of New Delhi Cases by Justus R. Hope, MD


May 19, 2021 - A study by Juan Chamie, Jennifer Hibberd of the University of Toronto and David Scheim of the US Public Health Service, shows the sharp rise, fall and resurgence in excess deaths (among the over 60 year-old cohort) in Peru as the virus waxed, waned and waxed again.


Apr, 2021: Prevention study from Singapore (N=3,037) showed "Positive impact of oral hydroxychloroquine and povidone-iodine throat spray for COVID-19 prophylaxis: an open-label randomized trial."

Ivermectin vs Hydroxychloroquine

Clinical evidence to date has reported promising results for Ivermectin in prevention, early treatment as well as late treatment for COVID-19. While both Ivermectin and Hydroxychloroquine might be useful for early treatment, Ivermectin has a broader potential benefit i.e. prevention, early treatment as well as late treatment / hospital treatment.

Can hydroxychloroquine and ivermectin be used together? The 2 drugs do not seem to have a between-drug interaction. However, no in vitro or in vivo studies have been conducted on the combined effect of HCQ and ivermectin on COVID-19 infection.

That said, the Zelenko protocol recommends that both hydroxychoroquine and ivermectin can be used together, especially for high risk patients. If you have started with only one, the second agent may be added after about 2 days of treatment if obvious recovery has not yet been observed.

Quercetin is a viable stand-in, if you simply cannot get hydroxychloroquine or ivermectin. Quercetin works best when taken with vitamin C and Bromelain, as vitamin C helps activate it and bromelain helps with the absorption. Do not forget to combine it with zinc.

Although ivermectin and hydroxychloroquine are relatively safe drugs, they are still synthetic chemicals that can have side effects. Quercetin and Vitamin D, C, Zinc 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. If you are on multiple medications, be aware of supplement-drug interactions that might enhance the possibilities of adverse effects.
