Zinc and vitamin c will help in building immunity against COVID-19.

Micronutrients, vitamin c, and zinc are critical for a well-functioning immune system. But, these sole supplements are unlikely to prevent COVID-19.

Micronutrients, vitamin c, and zinc are critical for a well-functioning immune system. But, these sole supplements are unlikely to prevent COVID-19.A high dosage of vitamin-c and Zinc are provided to COVID-19 patients to enhance their immune system. Research supports that Zinc has an antiviral effect that improves immune responses and suppresses viral replication. Hence, adequate vitamins and minerals are required for the immune system's proper functioning. Zinc has the potential to be a supportive treatment in COVID-19 because of its immunomodulatory and antiviral properties.

Studies have shown that zinc supplements could decrease COVID-19 related symptoms like lower respiratory tract infection. A research article published on the NCBI website speculates that Zinc can prevent COVID-19 due to its antiviral effects. But there is no evidence regarding the same.

For infectious diseases, vitamin-c is a protective cover and, its supplementation would support respiratory defense mechanisms, prevent viral infections, and reduce their duration and severity. Patients with acute respiratory infections have indicated decreased plasma vitamin-c concentration. This necessary protective action makes it a target of interest in COVID-19.

Currently, there are no medicines or vaccine for COVID-19, according to the World Health Organisation (WHO). Recent evidence has shown that nutritional supplements play a supportive role in COVID-19 patients. Nutrients such as zinc, vitamin-c, and d, along with omega-3 fatty acids administered to the patients, benefited from reduced COVID-19's impact and decreased hospitalization length. In Myth Busters, the WHO states that no meals or supplements can cure or prevent COVID-19, and it suggests maintaining a good diet for general health.

A balanced diet with fruits, vegetables, and whole grains helps to maintain a healthy immune system. Supplements on the market might help the improvement of immune health. However, although these supplements may provide a small benefit for immune health, they should not be used to replace a healthy lifestyle. Moreover, the intake of any vitamin supplement must be under the guidance of a healthcare provider.

The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
