With no proven vaccine to date, your immune system is key to keeping the COVID-19 coronavirus from infecting you and others around you since it helps prevent viruses, germs and bad bacteria from making you sick. One way of doing this is by practicing a healthy diet full of natural nutrient-rich food sources. However, with social distancing and home quarantine measures in place, you may have little time and space to buy those. Instead, there are products currently available online that are packed with essential immunity-boosting vitamins and minerals that your body need.
