FOR IMMEDIATE RELEASE
Further Insights into Covid-19 Etiology and Susceptibilityby Michael PasswaterOMNS (March 22, 2023) As we pass the three-year anniversary of the World Health Organization's declaration of Covid-19 as a global pandemic, more than 6.8 million deaths have been attributed to the SARS-CoV-2 virus with 1.1 million (16%) of those deaths occurring in the United States. Over 6 million Covid-19 patients have been hospitalized in the United States. Over five billion people have been vaccinated including 230 million people in the United States. [1] Yet there is still no consensus on the most effective treatment. From 2020 onward, informed by past experiences with infectious diseases, genomic analysis of coronaviruses, and early treatment efforts, some natural medicine advocates have suggested that adequate doses of glutathione, vitamin C, selenium, zinc, and vitamin D may be helpful. [2-10] Two recent studies deepen our understanding of how SARS-CoV-2 attacks our cells and tissues, and which individuals are at risk of becoming seriously ill from the infection. A study of 106 people in North Carolina with Covid-19 in late 2020 (all unvaccinated) showed selenium intake to be inversely related to Covid severity index among those with below average selenium and zinc intake (higher selenium intake = lower disease severity). [11] This is consistent with population studies in 2020 and 2021 in China associating more severe disease and mortality with lower regional selenium levels, and retrospective studies of hospitalized patients with Covid-19 in Germany identifying low total serum selenium and selenoprotein P status, along with advanced age and low zinc levels, as predictors of mortality. [12-15] A recent mechanistic study also confirmed the previously predicted destruction of host selenoproteins thioredoxin reductase 1 (TXNRD1), selenoprotein P (SelenoP), and selenoprotein F (SelenoF) by the SARS-CoV-2 Mpro protein. Additionally, this viral protease was shown to destroy glutamate-cysteine ligase catalytic subunit (GCLC) which is a rate limiting enzyme in the production of glutathione. Destruction of TXNRD1, SelenoP, SelenoF, and GCLC weakens host immune and antioxidant defenses, genetic replication "proof-reading", and hemostasis while also supporting a shift from DNA to RNA production within the cell - effectively hijacking the cell to become an RNA virus factory instead of a host DNA factory. [16] Together, these new publications add support to the central roles of selenoproteins (proteins containing one or more selenocysteine amino acids) and the sulfur containing antioxidant glutathione in preventing Covid-19 and similar infections. This is also consistent with successful studies that have suggested the use of IV glutathione and IV vitamin C to reduce the risk of viral infection and aid recovery. [17-20] A drop in glutathione levels impairs vitamin C recycling which dramatically increases the demand for vitamin C intake. Thus, a selenium deficiency may increase the risk of a severe viral infection, because it can cause deficiencies of glutathione and vitamin C, which can impair the body's ability to combat increased cellular oxidation and acidosis, and to support a robust response by immune cells. (See also "Vitamin C Levels in Critically Ill Covid-19 Patients" http://orthomolecular.org/resources/omns/v17n17.shtml ) Does this mean we should take massive amounts of selenium supplements upon testing positive? No, It means we should consume a well-balanced diet, supplementing as necessary to maintain a full supply of nutrients, including selenium (as selenium yeast or methyl-selenocysteine) to optimize our health and resistance to infectious disease. Steady moderation is a good approach with selenium (100 mcg/d) and other essential trace elements. It also means medical doctors should continue to explore the usefulness of selenite injections and similar interventions as part of the treatment of acute viral infectious disease outbreaks, and further study the usefulness of selenium and other micronutrient testing to evaluate disease susceptibility and prognosis as well as to target personalized interventions. Does this mean vitamin D isn't important for Covid-19 prevention or treatment? No. Vitamin D, selenocysteine, and cysteine have epigenetic and functional interdependencies. [21-25] Nutrients work best as a team. With approximately a billion chemical reactions occurring each second within each of the 37 trillion cells in the human body, a broad balanced array of nutrients is continually needed to build and sustain the sophisticated functions of human life. Most of us need to take vitamin D supplements (2,000 - 10,000 IU/d) throughout the winter months to maintain a healthy vitamin D status. To learn more: Selenium not only benefits the host constitution and defenses, but it also has positive impacts on the mutagenesis and pathogenicity of viruses. [26-27] Virus replication is unstable and allows frequent mutations. However, the viral environment influences the rate and character of these mutations. Several varieties of viruses, including influenza, enteroviruses, and coxsackie viruses, have been shown to rapidly take on more harmful characteristics when allowed to replicate in a selenium deficient environment. [28-31] Oxidative environments also increase the rate of viral mutations. [32-34] See also Viral Mutations and the Risk of Second-hand Malnutrition'" http://orthomolecular.org/resources/omns/v17n19.shtml Whether the invader is tuberculosis, poliovirus, influenza, SARS, Zika, SARS-CoV-2, mpox, invasive streptococcus, avian influenza, Ebola, venom, or the Andromeda Strain, the wisdom of Dr. Fred Klenner applies: "The answer to these emergencies is simple. Large amounts of ascorbic acid 350 mg to 700 mg per kilogram (2.2 lb) g body weight given intravenously. . . Ascorbic acid is also given, by mouth, as followup treatment. Every emergency room should be stocked with vitamin C ampoules of sufficient strength so that time will never be counted-as a factor in saving a life. The 4 gram, 20 cc ampoule and 10 gram 50 cc ampoule must be made available to the physician." [35]
"In my department and other hospitals we highly recommend the
Vitamin C goes to work fast - it doesn't need to be incorporated into proteins before it begins to help fight the invasion and support the host. It also offers benefit to every cell in the body, helping to support the intense metabolic bursts of activated immune cells, as well as helping maintain the integrity of blood vessels. In critical illness, large doses help counteract cellular acidosis and restore enzymes to constructive rather than destructive activity. It is not blocked by the blood-brain barrier. Aside from rare instances of G6PD deficiency, vitamin C has a tremendous safety profile over a very wide therapeutic range. Glutathione, selenocysteine, vitamin D, niacin, magnesium also are key nutrients to optimizing immune responses and recovery. [36-43] ConclusionThe threat of infectious diseases is ubiquitous. SARS-CoV-2 and many other RNA viruses have a destructive impact on selenoproteins and glutathione. Viral replication within selenium deficient, oxidative environments promotes more rapid and more pathogenic mutations. Selenium and glutathione are critical, but they are not silver bullets. Nutrients do their best work as a team. A strong base of selenium containing selenocysteine, sulfur containing cysteine, and zinc helps to optimize vitamin D, vitamin C, B vitamins, and essential lipids for overall wellness and infectious disease prevention. Four pillars of overall wellness and infectious disease protection are to: Sleep well; Exercise the body and mind well; eat well, supplementing as necessary and flexing up nutrient intake - particularly vitamin C - in proportion to the scope of infection; and cultivate a positive, grateful mindset and social support network.
