Why You Need Zinc

Zinc plays a critical role in hundreds of body processes, including cell growth, wound healing, sexual maturation, and even everyday taste and smell. In fact, zinc is used by every cell in the body, and studies show it plays a role in fighting everything from acne, to ADHD, diabetes and age-related vision loss. But perhaps best known for its role in the immune system, zinc helps to protect the body against colds, flu, conjunctivitis, and other infections. It’s one of the most crucial components of a strong immune system; people who are low in zinc have a harder time fending off garden-variety infections. Yet a surprising number of Americans don’t get enough of this nutrient. Because your body does not produce zinc, it depends on external sources for its supply.
