Role of vitamin C in COVID 19 treatment
Different researches based
Dietary supplements containing vitamin C along with vitamin D i.e are a safe, low-cost,as well as an effective way of improving the immune system fight off COVID19 and others acute respiratory tract diseases according to the research done by Adrian Gombart of Oregon State University’s Linus Pauling Institute & collaborators at the University of Southampton (U K), the University of Otago (New Zealand) & University medical center ( Netherlands).
