Abstract

An amino acid supplement containing 700 mg of cystine and 280 mg of theanine was administered to 4 patients during the treatment of SARS-CoV-2 virus infection. Negative reactions on polymerase chain reaction (PCR) testing were promptly obtained. Oral ingestion of cysteine and theanine (C/T) may promote SARS-CoV-2 virus elimination.
