Zinc is an essential nutrient that individuals need to support their immune system to help fight off viruses and bacteria. Zinc also helps our bodies make protein, and produce genetic materials in our cells. While you can get zinc from a variety of foods in your everyday diet - you can also take a supplement if you're deficient. Zinc is present in almost all multivitamin/mineral supplements. It is also available alone or combined with calcium, magnesium or other ingredients in supplements. For more ways to boost your immune health, check out this link.
