The Claim

Among critically ill patients with COVID-19 pneumonia, administration of high-dose intravenous vitamin C (6 g/day for 96 hours) was associated with a smaller increase in SOFA score over 96 hours (median change +1 vs. +3.5) and a reduction in ferritin levels (median decrease from 665 to 620 ug/L) compared to controls.

In plain English

In critically ill patients with COVID-19 pneumonia, intravenous vitamin C at 6 grams per day for four days was associated with a smaller rise in organ dysfunction scores and a modest drop in ferritin levels compared to patients who did not receive it.

See the scientific wording

Among critically ill patients with COVID-19 pneumonia, high-dose intravenous vitamin C (6 g/day for 96 hours) was associated with a smaller increase in SOFA score over 96 hours (median change +1 vs. +3.5) and a reduction in ferritin levels (median decrease from 665 to 620 ug/L) compared to controls, suggesting a potential modulatory effect on systemic inflammation and organ dysfunction.

Why this might work

High doses of vitamin C enter the bloodstream and soak up harmful molecules called reactive oxygen species that build up during severe infection. This stops a key signaling system from turning on genes that make too many inflammatory chemicals. With fewer inflammatory chemicals, blood vessels stay less leaky, organs don't get as damaged, and the body doesn't produce as much ferritin, a marker of inflammation.

    In very sick COVID-19 patients, giving high doses of vitamin C through an IV helped slow down the worsening of organ function and lowered a key inflammation marker, even though it didn’t make people leave the ICU sooner or reduce deaths.
