Research so far has shown the benefits of vitamin D and C against coronavirus as well as the crucial role of zinc and magnesium.

An article by Dr. Thanutchaporn Kumrungsee, published in Frontiers in Nutrition, promises to start the debate on another vitamin, found in fish, potatoes, and bananas, that appears to act against the coronavirus: vitamin B6.

“In addition to washing your hands, food and nutrition are among the first lines of defense against Covid-19 virus infection. Food is our first medicine and the kitchen is our first pharmacy,” details Dr. Kumrungsee who is an associate professor in the Department of Life Sciences at the University of Hiroshima.

In this article, she and her team pointed out the evidence that vitamin B6 protects against chronic diseases such as cardiovascular disease, diabetes by reducing inflammation and oxidative stress.

“Coronaviruses and influenza are among the viruses that can cause lethal lung injuries and death from acute respiratory distress syndrome worldwide,” she adds. 

As she explains further, thrombosis and the “cytokine storm” (hyperinflammatory condition) may be associated with the severity of the coronavirus. The “cytokine storm” is a self-destructive reaction of the immune system that severely worsens the condition of several patients with Covid-19. At the same time, thrombosis, which is also associated with the coronavirus, can damage vital organs such as the heart, lungs, liver, and kidneys.

According to her: “Vitamin B6 has a close relationship with the immune system. Its levels always drop in people under chronic inflammation such as obesity, diabetes, and heart diseases. We can see from the news that obese and diabetic people are at high risk for COVID-19.”

What is B6’s role in all this? Vitamin B6 is a nutrient that works beneficially against thrombosis and inflammation. It is noted that good sources of B6 are considered starchy vegetables, bananas, nuts, whole grains, beef liver, fish and poultry. Deficiency of this vitamin is associated with a weaker immune system and higher susceptibility to viral infections. 

So, by taking this particular vitamin from our diet, we strengthen our immune system and create the first line of defense against the coronavirus and other infections.

Although no clinical trials have been conducted to test this hypothesis, the researcher believes that this first hypothesis may shed light on how vitamin B6 may reduce the severity of COVID-19.
