Is excessive use of Vitamin C and Zinc Tab healthy?

As the second wave of pandemics hits the nation harder than before, a lockdown is under action. People are more educated and aware in comparison to the first hit of the virus.

They have started taking rules more seriously. Hand washing, masks, and sanitizers are not taken lightly and many people have been aware of the importance of multivitamin tablets or vitamins such as Vitamin C and Zinc. This has led to people consuming these medicines. 

However, is it safe? Are there any prescriptions? And if there are, what are some risks that come through these tablets?

These are some questions to understand properly before having such medicines by ourselves.

How did it start?

It is not pinpointed to one source or fact which started this idea of Vitamin C and Zinc fighting the COVID-19 virus but maybe instead of their general helpful properties.

Vitamin C and Zinc reduce the level of chemicals called cytokines that are harmful to the body and are produced in the body during infections. 

Zinc helps increase the production of these infection-fighting white blood cells and T cells. Vitamin C is also known for boosting immunity and is claimed to be most effective against respiratory-based illness. 

Since the virus is as dangerous as it is, there is no definite cure or medicine. COVID patients were given multivitamins and appropriate pain relief medicines. This is also probably why everyone started having supplements.

Another reason why these supplements have suddenly seen massive adoption is of course because of the Internet. There are many websites and videos on how having vitamin C and Zinc can help protect people from the virus. 

Why Vitamin C and Zinc?

Vitamin C and Zinc are two essential micronutrients that play functional roles in nutrition, immune support, and maintenance of health. Vitamin C is a highly effective antioxidant that protects proteins, lipids, and carbohydrates from damage.

Zinc is a crucial part of cellular differentiation and proliferation. It is helpful in reducing the risk of pneumonia and common cold and the incidence of respiratory tract infection as reported by hindawi.com.

Vitamin C and Zinc have been proven by many scientists to aid in symptoms closely related to the symptoms of the virus. 

However, the human body cannot produce or store vitamin C. The recommended Vitamin C dosage is 90 mg as reported by healthline.com.
