Vitamin C and the Treatment of COVID-19


There are thousands of studies in the peer reviewed literature about the use of varying doses of Vitamin C to combat viruses like COVID-19.  Vitamin C supports your immune system and helps to kill viruses, reducing infection symptoms. In laboratory experiments, Vitamin C has successfully killed every virus that it has been tested against, including influenza, Epstein Barr Virus and poliovirus.  There is now preliminary data confirming its benefit in COVID-19 patients.


Since the 1930’s doctors have used vitamin C to prevent and treat infection. There are over 64,000 published studies on vitamin C and the vast majority of the research is positive.  A dose as low as 200 mg has been shown to decrease mortality by 80% in hospitalized elderly patients with pneumonia. Vitamin C is even more effective in higher doses given intravenously. Intravenous vitamin C has been proven to decrease the risk of death from severe infection (sepsis & septic shock) from 40% down to 8%!  


A hospital in New York is already helping patients with high dose Vitamin C (HD IVC).  In a series of YouTube videos released within the last two weeks, Richard Cheng MD, PhD, Chinese Edition Editor of the Orthomolecular Medicine News Service states there are at least three clinical trials in China studying the effects of high-dose IV vitamin C for the treatment of COVID-19. The Shanghai Medical Association has released an expert consensus statement on the comprehensive treatment of COVID-19 where they endorse the use of high-dose IV vitamin C for the illness.  The link above opens in Chinese but you can easily use your Chrome browser to select “English” to translate the entire page.


You can read Dr. Cheng’s published article about his patient data and results with COVID-19 patients using high dose Vitamin C here.


An online meeting of physicians and scientists took place on March 17 to discuss the use of HD IVC in the treatment of moderate to severe cases of COVID-19 infection.  The key speaker was Dr. Mao, Chief of Emergency Medicine and a member of the Senior Expert Team at the Shanghai Public Health Center. He co-authored the Shanghai Guidelines for the Treatment of COVID-19 Infection.   


Dr. Engian Mao has been using HD IVC to treat patients with conditions such as acute pancreatitis, sepsis and surgical wound infections for more than 10 years.  Soon after the world recognized the COVID-19 pandemic , Dr. Mao and colleagues recommended IHD VC for patients with moderate to severe symptoms from COVID-19. 


Dr. Mao stated that his group treated 50 moderate to severe cases of COVID-19 infection with HD IVC.  Patients with moderate symptoms were given 10,000 mg of HD IVC while patients with severe symptoms were given 20,000 mg daily for 7-10 days.  All patients who received HD IVC improved and there was no mortality in the group.  Those patients receiving HD IVC treatment had hospital stays 3-5 days shorter than the typical 30-day stay for patients not receiving HD IVC.  Dr. Wang, Professor of Critical Care Medicine in Shanghai, also stated that early and HD IVC is extremely helpful in treatment of the Covid-19 infection.


Not waiting for the clinical data to be finalized as patients are in desperate need of treatment, Dr. Andrew G. Weber, a pulmonologist and critical-care specialist affiliated with two Northwell Health facilities on Long Island, said his intensive-care patients with the coronavirus immediately receive 1,500 milligrams of intravenous vitamin C.  


“The regimen is based on experimental treatments administered to people with the coronavirus in Shanghai, China, Weber said.  “The patients who received vitamin C did significantly better than those who did not get vitamin C,” he said. “It helps a tremendous amount, but it is not highlighted because it’s not a sexy drug.”


Based on the promising preliminary data, four additional studies are underway in China, South Korea and Singapore.  Italy has started a clinical trial at one of its hospitals that will give 10,000 mg IV vitamin C to all COVID-19 patients.  There is no proven preventative treatment for COVID-19 as of this date, but if you or your loved one develops serious symptoms from a COVID-19 infection, please consider asking your provider about the use of HD IVC.  The safety risk of HD IVC is very low while its potential is very high. Something to consider.
