- Zinc influences the acquired immune system through T-lymphocyte activation and regulation, Th1 cytokine production, B-lymphocyte function, and antibody production with subsequent immunoglobulin G formation.

- Zinc is also needed for skin and wound healing, cardiovascular function, mineral absorption, body temperature control, fertility, DNA synthesis, cell division, protein synthesis, growth, tissue repair, apoptosis, cytokine production, cancer resistance, and more
