Zinc and vitamin C intake increases spike and neutralising antibody production following SARS‐CoV‐2 infection.

Overall, seropositive men who were initially negative for neutralising antibodies were approximately four times more likely to develop neutralising antibody positivity by day 42 in the zinc + vitamin C group compared with other interventions (odds ratio (OR) 3.75, 95% confidence interval (CI) 1.69-8.32). Previous studies have not examined whether pharmacologic interventions could increase SARS-CoV-2 antibody responses. Future studies should examine whether increase in antibody production following zinc + vitamin C could sustain immunity against re-infection, and enhance antibody responses following vaccination among immunocompromised individuals. Zinc and vitamin C intake increases spike and neutralising antibody production following SARS-CoV-2 infection. [Extracted from the article]
