How Zinc May Boost Your Immunity

Zinc is a great way to boost our immune system! This natural element helps us stay healthy in many ways. By helping to boost our immune systems, we can fight off invading bacteria and viruses. Our bodies also use zinc to make proteins and DNA, the genetic material in all cells. Zinc is essential for our bodies to grow and develop properly. Plus, it also helps heal wounds and develop proper taste and smell.

This important chemical element is naturally found in the earth and also in some foods. Humans do not store Zinc, so we need to ingest it daily.
