Function/Recommended Dietary Allowance:
Zinc is an essential trace mineral for DNA synthesis, cell division, collagen formation, protein synthesis, and immune function - all necessary processes for tissue regeneration and wound repair. Zinc is necessary to develop and activate T-lymphocytes, which are important for the immune system. Alterations in immune function increase the risk of infection, especially in the elderly and the very young.
