Interaction guide

Zinc and copper balance

Long-term high-dose zinc can reduce copper status, so zinc labels need a total-dose and duration check instead of a simple yes/no answer.

Default spacing rule

Add up zinc from standalones, multis, lozenges, and immune products. If high-dose zinc is chronic, review copper context with a clinician.
