Vitamin C and Zinc Supplements not beneficial in treating symptoms of COVID 19
Vitamin C and zinc supplements are commonly used to fight off viral colds and flu. Since the pandemic began, both supplements have seen an increased market owing to people's belief that they can give the immune system a boost. But, in a recent study, researchers have found that treatment with high-dose zinc gluconate, ascorbic acid, or a combination of the 2supplements does not affect SARS-CoV-2 symptoms, even in a high dose. The study findings were published in the journal JAMA Network Open on February 12, 2021.
The consumption of Zinc and Ascorbic acid supplements have drastically increased since last year due to pandemic. The New York Times reported zinc sales of $134 million, and USA Today reported that vitamin C sales reached $209 million during the first half of 2020, up 76% compared with 2019. However, there is limited evidence regarding early treatment of novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection to mitigate symptom progression. To address this knowledge gap, researchers of Cleveland Clinic, Ohio, conducted a study, to examine whether high-dose zinc and/or high-dose ascorbic acid reduce the severity or duration of symptoms compared with usual care among ambulatory patients with SARS-CoV-2 infection.
