Upper and lower respiratory tract infections are among the most common infections globally, and in the United Kingdom, they account for about half of all oral antibiotics prescribed. Antibiotic overuse and the emergence of “superbugs” that are resistant to their effects is a global problem that is becoming a serious concern. Considering this, the potential role of immunonutrition as a “prehabilitation” in helping to tackle bacterial infections and reduce over-reliance on antibiotic usage is gaining interest. This narrative mini-review summarizes current knowledge on the roles of certain nutrients in helping to modulate immune function, with particular focus on vitamin D. Vitamin D supplementation appears to reduce the risk of acute respiratory tract infections and thus could have a valuable role to play in reducing over-reliance on antibiotics. Investment in high-quality trials is needed to further explore this field.

Objective: The aim of this review was to assess the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19, and how vitamin D supplementation might be a useful measure to reduce risk and also to outline the research progress and literature available of the epidemiology, pathogenesis, and clinical characteristics of COVID-19 patients information regarding the ongoing pandemic.Unani medicines can play significant role as adjuvent therapy to control the adverse effect of COVID-19 and can also act asa a best Immunomodulator. Methods: Aliterature search was conducted using the databases PubMed, Medline, Scopus and Web of Science. We described overall possible association between COVID-19 and Vitamin D. We have searched by the names corona virus, covid-19 and vitamin D association with COVID-19. Result: Through several mechanisms, vitamin D can reduce the risk of infections by lowering viral rates of replication and also reducing concentrations of pro-inflammatory cytokines that are responsible for the inflammation and injuries in the pleura. Conclusion: It was additionally observed that COVID-19 and vitamin D have a crude substantial relationship and specifically the mortality induced through this infection. The most susceptible crew of the populace for COVID-19, the getting old population, is additionally the one that has the most deficit Vitamin D levels.
