MAINTENANCE

15-30mg elemental zinc daily

For zinc oxide specifically, note that elemental zinc is ~80% of total weight (e.g., 50mg zinc oxide ≈ 40mg elemental zinc). Take with food to minimize nausea. For antibiotic interactions, separate by 2-3 hours. For long-term supplementation above 25mg/day, consider adding 1-2mg copper to prevent deficiency.
