You may have heard the news that a small trial carried out at the Cleveland Clinic in the US showed that vitamin C and zinc are useless against covid-19.
The results of the trial, called the ‘COVID A to Z’ trial, now published in JAMA Network is one of several studies being undertaken by the Cleveland Clinic on covid-19, and the only one involving the oral use of nutritional supplements.

Trial design: looking the business

The single-centre, prospective, randomised trial involved around 200 subjects and compared symptom severity, duration and hospitalisation in 4 different groups of patients with COVID-19 visiting the Clinic as outpatients.
The 4 groups of around 50 each received standard care, vitamin C (8 grams in 3 divided doses with meals) alone, zinc (50 milligrams as zinc gluconate at bedtime) alone, or both vitamin C and zinc (doses as previous). Treatments were initiated on confirmation of disease with a positive PCR test and continued for 10 days.
