You might have noticed the supplement with vitamin C segment looking empty these days or you may have seen the reports on social media that vitamin C can cure COVID-19. Whereas the effects of high intravenous ( IV) vitamin C on the new coronavirus are being examined by doctors and researchers, no treatment, including vitamin C, can prevent or treat COVID-19. This article discusses what vitamin C is, how it impacts immunity, how it is being used in a hospital environment for COVID-19 care and whether it is helpful to take an oral supplement.

What is vitamin C?

Vitamin C is a necessary nutrient in your body which has several roles. It’s a potent antioxidant, which means it can neutralize unstable compounds throughout your body called free radicals and help prevent or invert cellular damage from these compounds. This also participates in a variety of biochemical processes, many of which are associated with immune function.

Meeting your vitamin C needs through your diet is pretty easy, as long as you eat a variety of fruits and vegetables. For example, 77 per cent of DV is provided by a single medium orange, and 112 per cent of DV is provided by 1 cup (160 grams ) of cooked broccoli.

How does it affect immunity?

Vitamin C has a multiple effects on your immune system. The antioxidant activity can minimize inflammation, which can further strengthen the role of your immune system. Vitamin C also helps to keep the skin safe by stimulating the development of collagen and helping the skin act as a functional shield to prevent harmful substances from reaching the body. Vitamin C can also promote wound healing in the skin.

The vitamin also enhances phagocyte function, immune cells which can “swallow” harmful bacteria and other particles. Furthermore, it stimulates lymphocyte growth and spread, a type of immune cell that raises the circulating antibodies, proteins that can target foreign or harmful compounds in the blood.

Vitamin C does not appear to make you any less likely to get cold in studies of its efficacy against viruses that cause the common cold — but it may help you get through a cold faster and make symptoms less severe.

There is also some evidence of animal research and case studies in humans which high dose or IV vitamin C in serious respiratory diseases caused by H1N1 (“swine flu”) or other viruses may minimize lung inflammation. Both levels were well above the DV however, and at this point there is not enough evidence to justify the use of high-dose vitamin C for inflammation of the lungs. You should not take high doses — even orally — of vitamin C supplements because they can cause side effects such as diarrhea.

Vitamin C and COVID-19

The Shanghai Medical Association approved the use of high-dose vitamin C as a therapy for people hospitalized with COVID-19 in an article published in the Chinese Journal of Infection Diseases. Doses higher than the DV are advised to be given by IV to enhance lung capacity, which can help keep a patient away from artificial ventilation or life-support. In addition, a 2019 study showed that oral and IV high-dose vitamin C therapy could benefit people admitted to intensive care units ( ICUs) for serious diseases by reducing the length of stay in ICU by 8% and by shortening the mechanical ventilation time by 18.2%.

Chinese researchers have also reported a clinical trial to further study. The efficacy of IV vitamin C in people with COVID-19 in hospital. It is important to remember, however, that vitamin C is not yet a normal part of the COVID-19 treatment plan. Because there is still a lack of evidence.
