A recent study from Iran examines the effect of vitamin supplementation on disease severity and inflammatory responses in intensive care unit (ICU) patients suffering from COVID-19. Conducted in the form of a randomized clinical trial, a total of 30 patients were given a combination of vitamins A, C, D, E, and B complex. A further 30 patients functioned as the control group and received neither vitamins nor a placebo. At the end of the study, after evaluating the results and noting that not a single participant given the vitamins had died, the researchers confirmed that vitamin supplementation could improve the inflammatory response and decrease the severity of disease in ICU patients afflicted with COVID-19. The trial adds to the already impressive and growing volume of evidence that vitamins are powerful health-promoting tools in the fight against the coronavirus pandemic.
Conducted at the Imam Khomeini Hospital in Tehran, the stated goal of the study was to evaluate whether multivitamin supplementation could improve the laboratory and clinical outcomes of COVID-19 patients admitted to a hospital ICU. All of the patients taking part in the trial were informed about this goal and signed forms indicating their consent to participate. The study is published in the open access peer-reviewed medical journal Trials.
Saving lives and reducing hospital stays
Noting the synergistic effect of vitamins in strengthening immune system function, the researchers gave the patients in the intervention group the following supplement dosages during the 7-day study period:
