Effect and application of vitamin C on Immune function during the COVID-19 pandemic

Abstract

To present a fresh idea for the COVID-19 treatment, the vitamin C influence on the immunity of the novel coronavirus was studied, by browsing through the pertinent literature. Using keywords such as "vitamin C", "COVID-19", "nutrition" and "immunity", Chinese and English searches were conducted in PubMed, Google Scholar, CNKI, Wanfang Medical, and other databases to analyze and summarize the vitamin C immune effect on the epidemic situation of COVID-19. In the treatment of COVID-19 patients, it could be concluded that vitamin C could have a certain positive influence, but the specific mechanism, the best use time, and the correct dose still need to be studied
