Taking immune-boosting micronutrients, such as vitamin C, vitamin D3 and zinc, does not reduce the risk of dying from COVID-19, the results of a large meta-analysis including over 5,6 thousand people in total have shown. sick.
Vitamins for COVID-19?
In the “Clinical Nutrition ESPEN” (https://dx.doi.org/10.1016/j.clnesp.2021.12.033), researchers from the University of Toledo described their meta-analysis of 26 peer-reviewed studies from around the world, including over 5,6 thousand COVID-19 patients. They showed that – contrary to the suggestions of some communities – taking dietary supplements that strengthen immunity, e.g. vitamin C, vitamin D3 or zinc preparations, does not cause a milder course of the disease and does not reduce the risk of death.
“At the start of the pandemic, doctors tried various micronutrients as potential therapies for the new disease. We now know that there is no evidence that such strategies work. Despite this, we still see a lot of interest in them, and some even promote the use of supplements as an alternative to safe and proven vaccines, »says Dr. Azizullah Beran, lead author of the publication.

«Many people have the misconception that taking zinc, vitamin D3 or vitamin C will help improve the clinical picture of COVID-19. Meanwhile, it has not been proven in any way »- adds the scientist.
A thorough review of 26 importantly prior peer-reviewed scientific publications by Beran and colleagues found no reduction in mortality in those treated with vitamin D3, vitamin C, or zinc compared to patients who did not receive one of the three supplements.
Instead, the analysis showed that vitamin D3 treatment may be associated with lower intubation rates and shorter hospital stays, but the researchers say more rigorous studies are needed to confirm this finding.
Vitamin C and zinc were not associated in any way with shorter hospitalization or a reduction in the likelihood that the patient would be connected to a ventilator.
The main part of this study looked at patients who started taking supplements while they were already sick with COVID-19. Additionally, the researchers analyzed a smaller subgroup of people who had taken vitamin D before contracting the virus. And they also found no significant difference in the mortality rate of this population.
«It is important for people to understand that taking large amounts of these supplements does not translate into better results » – points out prof. Ragheb Assaly, co-author of the article. «The second important message is that the answer to COVID-19 is only a vaccine for now. No supplements or micronutrients will compensate for the lack of vaccinations or make the vaccine unnecessary ».
The researchers also warn that their study should not be interpreted as saying that vitamin and mineral supplements are bad and should be avoided. This just underlines the fact that they are not effective in preventing COVID-19 related deaths.
“We would like to emphasize that if a person does not need these supplements from a medical point of view – they should not take them thinking they protect against COVID-19,” concludes Dr. Beran. “They will not stop you from getting infected, or from being killed.”
