How to Choose a Zinc Lozenge Supplement
Early lozenge trials used 75–92 mg/day; do not exceed labels to copy them.
Check elemental dose and excipients; labels cannot establish ionic release.
Follow label limits. Research spans 5–7 days; chronic intake above 40 mg/day risks copper deficiency.
Nausea occurs. Ask about antibiotic/penicillamine spacing. Avoid intranasal zinc: smell-loss risk. Keep away from young children.
Read dietary zinc supplement guide and cold-season immune supplements.
