Vitamin C: your immune system guardian

10 June 2020

Coronavirus disease 2019 (COVID-19) is a virus (more specifically, a coronavirus) identified as the cause of an outbreak of respiratory illness. According to data as of 17 May 2020, 213 countries and territories around the world have reported a total of 4,739,796 confirmed cases of the coronavirus COVID-19, and a death toll of 313,773 deaths.

At this point, there is no specific treatment for coronavirus. Treatment aims to relieve the symptoms until patients recover. Scientists are laying the groundwork to develop a vaccine against COVID-19. Before the successful development of vaccine, the best way to prevent infection is to avoid being exposed and enhance immunity. When it comes to natural immune support ingredient, you cannot help but talk about Vitamin C.

Vitamin C

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin that is naturally present in some foods, added to others, and available as a dietary supplement. Humans, unlike most animals, are unable to synthesise vitamin C endogenously, so it is an essential dietary component. Vitamin C is required for the biosynthesis of collagen, L-carnitine, and certain neurotransmitters.

Vitamin C is also involved in protein metabolism. Collagen is an essential component of connective tissue, which plays a vital role in wound healing. Vitamin C is also an important physiological antioxidant and has been shown to regenerate other antioxidants within the body. In addition to its biosynthetic and antioxidant functions, vitamin C plays an important role in immune function and improves the absorption of nonheme iron, the form of iron present in plant-based foods. Insufficient vitamin C intake causes scurvy, which is characterized by fatigue or lassitude, widespread connective tissue weakness, and capillary fragility. One study out of Switzerland actually found that getting enough vitamin C can help reduce symptoms and shorten the duration of respiratory infections, such as the common cold, bronchitis or sinusitis. Plus, it could also improve the outcomes and reduce the incidence of other conditions like pneumonia, malaria and diarrhea infections as well.

How does Vitamin C contribute to immune defence?

Vitamin C affects your immune health in several ways. Its antioxidant activity can decrease inflammation, which may help improve your immune function. Vitamin C also boosts the activity of phagocytes, immune cells that can “swallow” harmful bacteria and other particles. In addition, it promotes the growth and spread of lymphocytes, a type of immune cell that increases your circulating antibodies, proteins that can attack foreign or harmful substances in your blood. Vitamin C appears to exert a multitude of beneficial effects on cellular functions of both the innate and adaptive immune system.

Although vitamin C is a potent antioxidant protecting the body against endogenous and exogenous oxidative challenges, it is likely that its action as a cofactor for numerous biosynthetic and gene regulatory enzymes plays a key role in its immune-modulating effects. Vitamin C stimulates neutrophil migration to the site of infection, enhances phagocytosis and oxidant generation, and microbial killing. At the same time, it protects host tissue from excessive damage by enhancing neutrophil apoptosis and clearance by macrophages, and decreasing neutrophil necrosis  and NETosis. Thus, it is apparent that vitamin C is necessary for the immune system to mount and sustain an adequate response against pathogens, whilst avoiding excessive damage to the host.
