Protection against COVID-19: Latest Research from US Scientists

Vitamin C

Let’s take a glass of water and drown a Vitamin C tablet in it. As it bubbles, we will explain how vitamin C can help us prevent COVID-19.

Oxidative stress plays an important role in the development of infections in our respiratory tract. It weakens immune defenses, worsens lung tissue damage and aggravates inflammation. As we know, the lungs are ground zero for coronavirus. Vitamin C has antioxidant and anti-inflammatory effects; therefore, it helps deactivate harmful free radicals and protect lung cells from their aggressive effects.

Vitamin C is also widely recognized as a stimulant for our immune system. It enhances the synthesis of interferon proteins, which are among the first to fight viruses.

Vitamin D3

Do experts recommend other vitamins to prevent infection? Naturally. The sunny Vitamin D3 is an overall regulator of immune response. Its sufficient intake enhances our antiviral protection. Global scientific reviews show the role of this nutrient in reducing the risk of respiratory tract infections. This background suggests that Vitamin D may be efficient in protecting us from catching coronavirus

British researchers recently attempted to identify the relationship between average vitamin D levels in a given country and the number of cases of COVID-19. They drew attention to very low levels of this vitamin in the inhabitants of Italy, Spain and Switzerland, especially among the elderly. It was in these countries that high mortality rate from the new infection has been observed. Despite some critical remarks about methodology and conclusions of this study, there is no doubt about the great importance of Sunshine Vitamin for our health.


During the pandemic, there was a high demand for zinc supplements worldwide, and this is no coincidence. Zinc insufficiency makes human immune system less active.

Currently, many researchers are focusing on zinc’s ability to block RNA polymerase enzyme in coronoviruses, thus preventing their reproduction. This trace element may also reduce the activity of another very important enzyme, ACE2, with which the virus binds to enter the cell.

So, new drugs for coronavirus prevention may contain zinc, in addition to other ingredients, as there is already some evidence of its beneficial effects.


In US, treatment guidelines include Quercetin. We can offer a substance that is similar to in its molecular structure and functions, with a complex name of Dihydroquercetin. It is a bioflavonoid extracted from Siberian larch. In Russia, as well as in US and Europe, it is well-known under the name of Taxifolin.

Dihydroquercetin is a unique natural broad-spectrum bio-regulating substance. It is a benchmark antioxidant that prevents free radicals from destroying cell membranes and curbs inflammation. It also promotes oxygen and energy supply on cellular level.

To top it all, dihydroquercetin strengthens the walls of blood vessels, improves microcirculation, boosts immune defenses, and demonstrates antiviral and a number of other properties that help maintain functional activity of the lungs. Latest research data from China shows that dihydroquercetin has a great potential in fighting coronavirus.


You may wonder how this lullaby hormone can help protect us from infection at all. Melatonin is indeed primarily known as a regulator of wakefulness and sleep cycle. But who says that this is its only property? Melatonin is a unique molecule that has a regulatory effect on many physiological functions and processes in the body. It also has antioxidant, anti-inflammatory and immunomodulatory effects. Sleep-promoting effects of melatonin are just another advantage in this situation. Everybody knows that chronic lack of sleep increases the risk of catching infection. Melatonin also demonstrates anti-anxiety and antidepressant properties, offering precious moral support in hard times of lockdown.
