From the very beginning of the pandemic, there has been widespread discussion about which vitamins and micronutrients should be taken to reduce the risk of infection or speed up recovery. In particular, it is believed to be very beneficial to take zinc supplements, ascorbic acid (vitamin C), or a combination of both. However, there has been no scientific basis for such recommendations so far, although it is known that both of these substances really have a positive effect on the functioning of the immune system.

To understand this issue, the study authors recruited 214 patients with confirmed coronavirus infection. All of them were treated at home. The participants were randomly divided into four groups: for ten days, the first group received a zinc gluconate supplement (50 milligrams), the second – Vitamin C (8,000 milligrams), the third was a combination preparation with zinc and vitamin C, and the fourth received standard treatment.

As a result, the experiment had to be stopped due to its meaninglessness, since no significant difference was observed either in the severity of symptoms or in the duration of the disease between participants from different groups.

Despite the apparent uselessness of zinc and vitamin C supplements for covid, scientists continue to hope that they will still be able to find those vitamins and trace elements that can help prevent and treat infection, so research in this direction continues.
