This 30mg zinc tablet lands right at the top of the clinically studied range for immune support — and it's the well-absorbed glycinate-chelated form, so your body actually takes up most of what's on the label. **Zinc** has strong meta-analysis backing for immune function and wound healing, and 30mg daily covers it comfortably.
One thing to know for daily long-term use: zinc competes with copper for absorption, and sustained intakes near this level can gradually lower copper stores. If you're taking this every day for months, pairing it with 1–2mg of copper keeps that balanced. For short-term immune support, it's not a concern.
