Vitamin D Focused Approach to Nutritional Therapy for the Management of SARS-CoV-2 Pandemic: A Review

Abstract

Background: In several studies, Vitamin D supplementation was found useful against the highly infectious SARS-CoV-2 to reduce the mortality rate and severity of its infection. Viral replication was also found to be affected negatively with vitamin D administration. Objective: The study was performed with an aim to study the efficacy of therapeutic approach of nutrition by 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 key words “SARS-CoV-2”, “Covid-19”, “nutritional therapy”, “Vitamin D”, “immunity”, “AEC2 receptors” and “RAS system” in pubmed and google scholar. Results: 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 to human kind. 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. Conclusion: Nutritional therapy with Vitamin D as a major factor can be used to increase the immunity of an individual to fight against the highly infectious SARS-CoV-2. However the actual mechanism about how Vitamin D supplementation functions to improve health of an individual is yet unclear.
