Objective: The literature was reviewed with an aim to evaluate the efficacy of the therapeutic \napproach of nutrition involving intervention of Vitamin D towards decreasing the severity of prevailing pandemic of SARS-CoV-2. Methods: A background research of literature was performed using the keywords "SARS-CoV-2", "COVID-19", "nutritional therapy", "Vitamin D", "immunity", "AEC2 receptors" and "RAS" in the Pubmed and Google Scholar. Results: This literature was review suggested that if combined with medical sciences, this nutritional therapy approach can end up as an influential solution to reduce the severity of SARS-CoV-2 infection, which is a prevailing pandemic. A combination of assessment, supplementation of this required micro-nutrient (Vitamin D), and monitoring can be used to aid the immune system of COVID-19 patients.
