This case study was based on the novel opinion that daily intake of vitamin C can serve as a prophylactic and curative intervention for the coronavirus disease of 2019 (COVID-19) via homeostatic and epigenetic mechanisms. To substantiate this hypothesis, some Nigerians who used vitamin C based regimen consented to share their experience in the prevention and management of the coronavirus irrespective of their country of abode. Participants all agreed to the use of their information for the public, albeit anonymous, via appending their signatures on an informed consent form. The documented cases took place from March 15 to September 1, 2020, this was to allow for more time to be able to observe the participants. The study provided evidence that regular use of Ascorbic acid tablets and vitamin C enriched plants could improve the immunity needed against the infection of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).
