Vitamin C for COVID-19
6th treatment shown to reduce risk in September 2020
*, now known with p = 0.000000087 from 70 studies, recognized in 11 countries.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.
4,000+ studies for 60+ treatments.
In Silico study showing significant interaction with SARS-CoV-2 targets for multiple vitamins.
12 preclinical studies support the efficacy of vitamin C for COVID-19:
Vitamin C has been identified by the European Food Safety Authority (EFSA) as having sufficient evidence for a causal relationship between intake and optimal immune system function EFSA, Galmés, Galmés (B). Vitamin C plays a key role in the immune system, supporting the production and function of leukocytes, or white blood cells, which defend against infection and disease, including the production of lymphocytes, which make antibodies, and enhancing phagocytosis, the process by which immune system cells ingest and destroy viruses and infected cells. Vitamin C is an antioxidant, protecting cells from damage caused by free radicals. Vitamin C inhibits SARS-CoV-2 3CLpro Malla, Đukić and inhibits SARS-CoV-2 infection by reducing ACE2 levels in a dose-dependent manner Zuo. Intracellular levels of vitamin C decline during COVID-19 hospitalization suggesting ongoing utilization and depletion of vitamin C Boerenkamp. Threonic acid, a metabolite of vitamin C, is lower in mild and severe cases, consistent with increased need for and metabolization of vitamin C with moderate infection, but more limited ability to produce threonic acid in severe infection due to depletion or existing lower levels of vitamin C Albóniga. Symptomatic COVID-19 is associated with a lower frequency of natural killer (NK) cells, and vitamin C has been shown to improve NK cell numbers and functioning Graydon, Vojdani.
Study covers vitamin D, vitamin C, vitamin A, vitamin B9, and vitamin B12.
