Zinc — useful, but balance matters
Zinc is involved in immune function, wound healing, taste, smell, and many enzymes. It is common in multis, immune blends, lozenges, and standalone products, which makes accidental stacking easy.

Evidence level
Strong for deficiency correction; limited for many broad wellness claims.
Common misunderstanding
People often treat zinc as harmless because it is common in immune products, but high chronic intake can disrupt copper status.
Practical tracking note
Track zinc across every product in your stack, especially during cold-season “immune” routines that combine multis, lozenges, and standalone zinc.
Safety note
Long-term high-dose zinc can cause copper deficiency and other issues. Zinc can also interact with certain antibiotics and other medications.
