COVID-19 or the novel Corona Virus is highly contagious and acute disease and is caused by Severe Acute Respiratory Syndrome Coronavirus-2 or SARS-CoV-2. The pathogenesis of Corona Virus is very complex and involves the suppression of host innate and antiviral immune response, cytokine storm is described as induction of oxidative stress followed by hyper inflammation which causes tissue fibrosis, pneumonia and lung injury. Several neutraceuticals have proven their abilities against viral pathogenesis and boosting immunity. These neutraceuticals involves Vitamin C, Vitamin D, Zinc, Selenium, and Copper. To boost immunity, combination of some of the phytonutrients may be used as food supplements. It may also help provide therapeutic assistance against COVID-19, preventing spread of virus and suppression of hyper inflammation. This review speculates the significance of nutrition as a mitigation strategy to support immune function amid the COVID-19 pandemic, identifying food groups and key nutrients of importance that may affect the outcomes of respiratory infections. To survive in the current conditions of COVID-19 it is necessary to build up the immunity. An appropriate diet can make sure that a body is capable against the viral pathogenesis.

Key words:    COVID-19, neutraceuticals, Vitamin C, Vitamin D, Zinc, Selenium, Copper
