Zinc for immune support: how it helps prevent infections

Zinc helps immune cells develop and communicate, and it supports skin and wound healing. Low zinc is linked to more frequent and longer infections.

Food first, then supplements

Oysters, beef, beans, pumpkin seeds and fortified cereals are good sources. Lozenges started within 24 hours of a cold may shorten it slightly.

Too much zinc blocks copper absorption and can interact with antibiotics. Check with our pharmacists before adding a high-dose supplement.
