Zinc
The Immune System's Essential Trace Mineral
Overview
Zinc is critical for the development and function of immune cells. It's required for the activity of over 300 enzymes and plays a vital role in T cell maturation, NK cell function, and the production of antibodies. Zinc deficiency significantly impairs immune function.
Key Benefits
- Essential for T cell development and function
- Supports NK cell activity
- Required for wound healing
- Has antiviral properties
- Supports thymus gland function
How It Works
Zinc is required for thymulin, a hormone produced by the thymus gland that's essential for T cell maturation. It also acts as a signaling molecule for immune cells and can directly inhibit viral replication. Zinc fingers are structural motifs in many immune-related proteins.
Typical Dosage
RDA is 8-11mg for adults. Supplemental doses typically range from 15-30mg daily. Higher doses (up to 50mg) may be used short-term during illness. Balance with copper (2mg copper per 15mg zinc) for long-term use.
