IF VITAMIN C CAN PROTECT YOU FROM COVID -19?
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 keeps your skin healthy by boosting collagen production, helping the skin serve as a functional barrier to keep harmful compounds from entering your body. Vitamin C in the skin can also promote wound healing.
The vitamin 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.
In studies of its effectiveness against viruses that cause the common cold, vitamin C doesn’t appear to make you any less likely to get a cold — but it may help you get over a cold faster and make the symptoms less severe.
There’s also some evidence from animal research and case studies in humans that high dose or IV vitamin C can reduce lung inflammation in severe respiratory illnesses caused by H1N1 (“swine flu”) or other viruses.
However, these doses were far above the DV, and there’s not enough research to support the use of high dose vitamin C for lung inflammation at this time. You shouldn’t take high doses of vitamin C supplements — even orally — because they can cause side effects like diarrhea .
Vitamin C is an important nutrient found in fruit and vegetables that may help shorten the duration and severity of colds. High doses are being studied for their potential to decrease lung inflammation, but more research is needed.
In an article published in the Chinese Journal of Infection Diseases, the Shanghai Medical Association endorsed the use of high dose vitamin C as a treatment for hospitalized people with COVID-19.
Doses that are magnitudes higher than the DV are recommended to be given through IV to improve lung function, which may help keep a patient off of mechanical ventilation or life support.
Additionally, a review found that both oral and IV high dose vitamin C treatment may aid people admitted to intensive care units (ICUs) for critical illnesses by reducing ICU stay length by 8% and shortening the duration of mechanical ventilation by 18.2%.
Chinese researchers have also registered a clinical trial to further study the effectiveness of IV vitamin C in hospitalized people with COVID-19.
However, it’s important to note that vitamin C is not yet a standard part of the treatment plan for COVID-19 because evidence is still lacking.
Though high dose IV vitamin C is currently being tested to see if it can improve lung function in people with COVID-19, no evidence suggests that high doses of oral vitamin C supplements can help with the disease. In fact, they can cause complications like diarrhea.
High dose IV vitamin C has been used in China to help improve lung function in people with COVID-19. However, vitamin C’s effectiveness is still being tested. There’s no evidence to support the use of oral vitamin C supplements for COVID-19.
Currently, no evidence supports the use of oral vitamin C supplements to prevent COVID-19.
