Role and Effects of Micronutrients Supplementation in Immune System and SARS-Cov-2(COVID-19)

Main Article Content

Akibul Islam Chowdhury


COVID-19 is a serious disease caused by the virus SARS-CoV-2 which is easily transmitted to humans. There are no vaccines or drugs discovered yet to control its transmission and prevent the disease. In that case, it is important to find the methods of preventing and controlling it. To fight against the virus a well-functioning immune system is necessary. The immune system is always active but if an individual becomes infected then the activity of immune system is enhanced to fight against the virus and recover the body from infection. Adequate intake of micronutrients through diet (vitamins A, B-complex, C, D and zinc, selenium, copper, iron) can help to boost up the immune system as each of the nutrients named above has roles in supporting antiviral and antibacterial defense. Although the supplementation of micronutrients can be given, it is necessary to provide the right amount of supplements after assessing the nutritional status of each individual as supplementation of micronutrient have some adverse effects. Therefore, it is recommended to follow a healthy diet to prevent COVID-19 and also assess the nutritional status of COVID-19 patients before prescribing treatments.
