Supplement with 500 milligrams of vitamin C increases survival chances in life-threatening covid by a factor of 5
A daily dose of 500 milligrams of vitamin C increases the survival chances of critically ill covid patients.
Study
In December 2021, a group of doctors from Iran published a trial in Frontiers in Virology in which 120 seriously ill covid patients who were in the ICU participated. 31 of them took 500 milligrams of vitamin C every day for 14 days through their enteral feeding.
The other patients received no extra vitamins.
Results
After 2 weeks of supplementation, 16.1 percent of the subjects in the vitamin C group were still alive. In the control group, only 2.9 percent of the subjects survived.
The patients in the vitamin C group survived an average of 8 days, the patients in the control group only 4 days.
Mechanism
"Vitamin C could possibly improve the treatment of patients with COVID-19 by enhancing the immunological response against viral infections and the direct effect against viral replication", the Iranians write.
"It also suppresses cytokine storm through its antioxidant and anti-inflammatory effects. In addition, vitamin C increases interferon production and stimulates lymphocyte proliferation, thereby improving the host antiviral immune response."
Conclusion
"Daily supplementation of 500 mg vitamin C resulted in an increase in the survival duration of the patients", summarize the researchers. "Further clinical studies are needed to confirm the effect of vitamin C on COVID-19."
