Zinc, vitamin C supplements does not decrease duration of COVID-19 symptoms: study

Taking zinc or vitamin C supplements does not significantly decrease the severity or duration of symptoms in COVID-19 patients, when compared to standard care, according to a study. Researchers at Cleveland Clinic in the U.S. noted that zinc is known to be important for immune function, with a role in antibody and white blood cell production and fighting infections. Vitamin C, an antioxidant, can help reduce damage to cells, and has shown to be immune-boosting, they said.
