What is Zinc?

An essential mineral your body needs for immune function, wound healing, growth, and many enzyme reactions.

Zinc is a mineral involved in immune defense, wound healing, growth, and the activity of many enzymes. Lower levels can be associated with poor intake or absorption and, over time, with issues such as slower wound healing or reduced immune function, though the blood test is an imperfect snapshot of the body's total zinc. Higher levels are usually related to supplement use. Most people in the United States get an adequate amount of zinc, so deficiency is not common here.
