Preventing zinc deficiency, preventing (or surviving) covid

Because the readers of this web magazine are well informed, they know that zinc supplementation can be helpful for a faster recovery from the common cold. Recent scientific studies suggest that an adequate zinc status can also reduce the risk of corona and the risk of serious complications from corona.

Study
Doctors at the Dr. Rela Institute and Medical Centre, a teaching hospital in Chennai, India, determined the zinc concentration in the blood of 47 corona patients, and compared it with the zinc status of 45 people without covid.

In the patient group, the researchers also determined the severity of the disease.

Results
The zinc level of the corona patients was lower than that of the control group. 57.4 percent of corona patients had less zinc in the blood than is optimal according to nutrition scientists. In the control group, this percentage was only 11.1 percent.

In the group of corona patients, the researchers found links between the severity of the infection and the zinc level. A low zinc level seemed to increase the chances of a long hospital stay and the chance of death.

Mechanism
The researchers suspect that zinc inhibits the replication of the virus in human cells, while at the same time facilitating the production of the immune cells that fight the coronavirus.

Conclusion
"This study clearly demonstrated that COVID-19 patients were zinc deficient when compared to healthy adults", write the researchers. "It is convincing that low baseline zinc levels in these patients were associated with more complications, leading to prolonged hospitalization and increased mortality."

"It is not clear whether zinc supplementation after admission to hospital helps to reduce the severity of disease. It is worth exploring the exact role of zinc in COVID-19 patients and establishing the appropriate dosage to improve their survival."

"With more research, zinc could provide a cost-effective therapy for COVID-19, certainly the need of the hour in this pandemic."
