Zinc is found in cells throughout the body. It helps the immune system fight off invading bacteria and viruses. Zinc is essential for our immune system because it affects how our cells respond to infections. It can also help keep inflammation under control.
Zinc increases the activation of cells in the body that are responsible for fighting infection. It also activates enzymes that break down proteins in viruses and bacteria to reduce the chances of spreading.
Due to its direct antiviral properties, it can be assumed that safe zinc administration is likely beneficial for most of the population, especially those with suboptimal zinc status.
