Which mineral is essential for the production of protein and genetic material, wound healing, reproductive maturity, and immune health?

• A. Calcium
• B. Iron
• C. Zinc
• D. Selenium

Answer: (C)

Zinc is the mineral that fits all four roles because it acts as a key cofactor in many enzymes involved in protein synthesis and DNA replication, helping cells divide and genes be expressed correctly. It supports wound healing by promoting collagen formation and the rapid proliferation of skin and other tissues needed for repair. For reproductive maturity, zinc is essential for normal growth and development and influences hormone metabolism, with deficiency able to delay puberty and impair reproductive function. In immune health, zinc is crucial for the development and function of immune cells, helps maintain barrier defenses, and modulates inflammatory responses.

Other minerals support different roles: calcium mainly for bones and signaling; iron for oxygen transport; selenium for antioxidant defenses and thyroid function. But the combination of protein/DNA production, tissue repair, growth maturation, and immune support aligns best with zinc.
