Vitamin C for COVID-19
7th treatment shown to reduce risk in September 2020
*, now known with p = 0.000000098 from 67 studies, recognized in 10 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
3,800+ studies for 60+ treatments.
Retrospective 19 COVID-19 ECMO patients in South Korea, showing a higher rate of weaning from ECMO with vitamin C treatment, without statistical significance. Authors perform multivariate analysis but do not provide full results, only reporting p > 0.05.
This is the 9th of 67 COVID-19 controlled studies for vitamin C, which collectively show efficacy with p=0.000000098 (1 in 10 million). 18 studies are RCTs, which show efficacy with p=0.00088.
This study is excluded in the after exclusion results of meta analysis: very late stage, ECMO patients.
Study covers vitamin B12 and vitamin C.

Background: The COVID-19 pandemic has caused an epidemic of critical patients, some of whom have been treated with extracorporeal membrane oxygenation (ECMO). This purpose of study is to describe the clinical course of COVID-19 patients treated with ECMO. Methods: A multicentered study of critical patients with COVID-19 treated at six hospitals in Daegu was conducted between January and April 2020. Results: Among the 80 patients receiving mechanical ventilation support, 19 (24%) were treated with ECMO included (median age 63.0 years). Eight of the 19 patients (42%) were weaned off ECMO (9.8 days, IQR 7.0-13.7). Among them, four patients were also weaned off mechanical ventilation (33.4 days, IQR 29.3 -35.7), three were still receiving mechanical ventilation (50.9 days), and one expired after ECMO weaning. According to the univariate analysis, the factor that was associated with successful ECMO weaning was vitamin B12 treatment (p = 0.028). Conclusions: During the COVID-19 epidemic, ECMO weaning and mortality rates were 42% and 58%, respectively.
