Zinc

Key trace element for immunity, wound healing, and growth.

Definition

Zinc is an essential trace element and cofactor for over 300 enzymes. It is indispensable for immunity, wound healing, growth, fertility, and taste and smell functions.

How it works

Zinc activates T lymphocytes and NK cells, accelerates wound healing, participates in testosterone synthesis, and is essential for taste and smell. Deficiency causes immunosuppression, alopecia, hypogeusia (reduced taste), and growth retardation.

Role

Immunity, wound healing, DNA synthesis, growth, male fertility, sensory functions.

Examples

  • Oysters (16-30mg/100g)
  • Red meat (5mg)
  • Legumes (3mg)
  • Pumpkin seeds (7mg)

Recommendations

RDA: 10-11mg/day. Phytates in plant-based foods reduce absorption — soaking legumes improves bioavailability.

Key takeaway

Zinc is the mineral of immunity — early supplementation reduces the duration of the common cold by 33%.
