Background

With hundreds of thousands of new cases being reported every day, over a year after its onset, the coronavirus disease 2019 (COVID-19) pandemic is still making its presence felt worldwide. Although vaccines are available, alternative treatments are being explored for people who can not or do not want to be vaccinated. The drawbacks of the current anti‑viral drug used to treat COVID‑19 are that it requires intravenous delivery and that it is only administered to hospitalized patients. Therefore, there is a need for a remedy that is very safe and effective so that it can be used broadly to prevent and treat multiple respiratory infections. Many are looking towards nutritional supplements to address this need.
