31 Mar 2020 --- Northwell Health, New York state’s largest healthcare provider, is administering large doses of vitamin C to some COVID-19 patients in its hospitals. A spokesperson for Northwell Health tells NutritionInsight that the provider is “exploring many therapies at this time, including utilizing vitamin C.” While the spokesperson declined to elaborate, the New York Post reports that intensive-care patients are immediately receiving 1,500 mg of intravenous vitamin C, which is then re-administered three or four times a day. The news comes as a clinical trial with vitamin C is underway in China, examining to what extent coronavirus symptoms can be treated.
