A research team recently conducted a new study to determine whether immune system supplements could offer protective effects against coronavirus. The gastroenterologists looked for a scientific justification and possible benefits, as well as disadvantages in clinical studies for the treatment of COVID-19. Economic analyzes show that taking supplementation as a preventive measure against Sars-CoV-2 can be traced back to the pandemic.
How immune supplements can help against COVID-19
The lead study author and his colleagues focused their research on melatonin, vitamin C, vitamin D and zinc. Plus, they highlight various herbal compounds like green tea and curcumin. For example, the authors explain that ascorbic acid, also known as vitamin C, contributes to immune defense by supporting the cell functions of both the innate and adaptive immune systems. In the journal article, they discuss the mechanisms by which each of the immune system supplements work and how each one could be of benefit to a patient battling COVID-19. Zinc, for example, has been shown to inhibit coronavirus RNA replication. The team also found that taking zinc when symptoms started can shorten the duration of the illness. However, the latter is due to more harmless coronavirus infections such as a cold.
Finally, the lead author of this study and his colleagues provide brief explanations of the ongoing clinical research. In doing so, the team wanted to test the effectiveness of each dietary supplement in fighting COVID-19. The researchers claim that there is ample data linking low vitamin D levels to higher susceptibility to COVID-19. However, the authors caution that any benefit of supplements against the coronavirus depends on the results of randomized controlled trials and peer-reviewed literature. It is already known that the pathogenesis of COVID-19 includes an inflammatory phase. This has the potential to develop into a cytokine storm and is characterized by high levels of interleukin (IL) -6 and other markers of inflammation. Frequently used immunomodulating food supplements, which are being researched in this study, could therefore have a biological plausibility for a beneficial benefit.
