Selenium Status and Covid-19 Patients

In cases of severe Covid-19 disease, patients have significantly lower concentrations of selenium and selenoprotein P and significantly higher levels of oxidative stress. That is to say, there is a more intense formation of harmful free radicals in patients with severe Covid-19 disease [Skesters 2022].

Corona virus
An adequate supply of selenium and zinc and vitamin D is essential for resistance to the corona viruses and to other viral infections. Here, Skesters er al show that Covid-19 patients have significantly lower levels of plasma selenium and selenoprotein P and significantly higher levels of oxidative stress.

Note: Oxidative stress is the bio-medical term for an imbalance between harmful free radical activity and protective antioxidant activity. Selenium is a key component of antioxidant selenoproteins such as the glutathione peroxidases and the thioredoxin reductases.

Role of Selenium and Selenoprotein P in Covid-19 Disease

Researchers have been investigating the role that selenium may play in reducing the severity and mortality of Covid-19 infections. Studies have shown a close relationship between low selenium status, Selenoprotein P deficiency, oxidative stress level, and Covid-19 disease incidence, severity, and prognosis [Skesters 2022]. read more

Selenium Deficiency and Heart Failure

Heart failure – the inability of the heart muscle to pump a sufficient quantity of blood out to the body – is a debilitating disease, resulting in shortness of breath, congestion in the lungs, and pooling of blood in the lower extremities. Heart failure is equivalent to diminished quality of life.

Mitochondrion
Depiction of a mitochondrion. The mitochondria in our cells convert energy sources such as fatty acids, glucose, and ketones into ATP energy molecules. Sufficient intakes of micronutrients such as selenium, Coenzyme Q10, and zinc are important for mitochondrial energy production and for antioxidant protection of cells, lipids, proteins, and DNA.

The prognosis for heart failure is poor, and the available medical therapies for patients with heart failure are inadequate. New treatment strategies are needed [Mortensen 2015].

Yin et al have analyzed the data from 39,757 adults in a cross-sectional study from the 2005–2018 US National Health and Nutrition Examination Survey. Their findings suggest that high levels of combined dietary antioxidant micronutrients are associated with decreased prevalence of various forms of cardiovascular disease and that selenium has the greatest contribution to this association [Yin 2022]. read more

Selenium Supplementation Strengthens Immune Response to Covid-19

The available vaccines do not seem up to the task of preventing infection by the fourth wave of the Covid-19 virus. Accordingly, people in high-risk groups may want to start on a course of supplementation to address possible deficiencies of selenium, zinc, and vitamin D to strengthen their immune response [Alexander 2020].

Covid-19 vaccine
Resistance to Covid-19 and other viral infections, strengthening of immune system function, and reducing chronic inflammation all depend on adequate intakes of zinc, selenium, and vitamin D [Alexander 2020].
In this article, we will address the importance of adequate selenium intakes. Readers are encouraged to google zinc and Covid-19 and vitamin D and Covid-19 on their own.

Early initiation of adequate selenium, zinc, and vitamin D supplementation in high-risk individuals and in high-risk areas and, certainly, as soon as possible after the time of suspected infection with the Covid-19 virus can help the immune system [Alexander 2020]. read more
