High-dose vitamin C can counter severe Covid

Vitamin C can counter the worst symptoms of a Covid-19 infection, and even save lives, a new study has found.

Patients in critical care are more likely to survive if they are given IV (intravenous) doses of the vitamin—and those with less severe symptoms can also recover quicker if they take vitamin supplements.

Covid patients tend to have extremely low levels of the vitamin that are comparable to people with sepsis and septic shock, say researchers from the Institute for Optimum Nutrition.

They analysed 12 studies that had looked at the relationship between vitamin C levels and severity of a Covid infection.  

Critical patients need at least 2 to 3g of vitamin C every day—and for much longer than the two to four days the therapy is typically used in hospitals.  When patients do get high doses intravenously for longer periods, the severity of an infection can be reduced and can reduce mortality rates, the researchers found.  

High doses are especially vital in patients with any severe respiratory infection as the condition uses up large amounts that are in the body.
