Is Zinc Useful to Boost Immunity Against COVID-19?

It is rightly said what we eat is what makes our body and who we are. A diet giving us every required nutrient in the right quantity is very important for healthy human sustenance. When our body has all the nutrients in the right quantity available, then our immune system is directly affected, and we can fight all the infections. We get to have good immunity and high resistance from diseases.

Sometimes people can’t have all the required nutrients in their diets, so additional supplements are also needed along with a balanced diet. 

We have seen in this pandemic that people who had good immunity have had the edge over those who didn’t for tackling coronavirus disease. People were advised to take additional supplements for vitamin A, vitamin c, zinc, etc. Let us look at how zinc is so important to tackle COVID-19.

Why is zinc such an important element?

Zinc is essential for the human body, and it plays a wide variety of roles. Zinc helps in pro-activating more than 300 enzymes in our body for enhancing our metabolic procedures. Zinc supplements are also given to people for the proper running functioning of the body at times of reproductive needs. Zinc is also a very important element for cardiovascular activities and enhancing nervous system functioning. 

What happens when zinc is deficient? 

Any nutrient in lower amounts than the required quantity in the human body can lead to a condition called deficiency of that nutrient. Any nutrient deficiency leads to the body becoming a target of many diseases and infections. 

Zinc deficiency causes conditions like a delay of growth in children and higher risks of getting infections. The deficiency of zinc also causes pneumonia risks in people who are suffering from coronavirus disease. 

As for the latest reports, more than 1.5 billion people are at risk of deficiency of zinc in the world. 

What are the effects of zinc on the immune system?

The human immunity system works upon the white blood cells, which fight with every kind of pathogen, causing all the diseases and infections. Different types of WBC are responsible for repairing, making antibodies, capturing and killing pathogens, and recovering the immune system after going through disease. Zinc is very important because zinc works as a support system in the production and growth, and maintenance of white blood cells. 

Zinc also plays another important function in anti-inflammation. It regulates inflammation and helps to fight infections by reducing the overproduction of cytokines which have pro-inflammatory effects. 

Zinc also helps in inhibiting the reproduction of disease-causing pathogens like rhinoviruses that are responsible for a  wide variety of diseases like the common cold and other respiratory disorders in people.
