Enter values above and click Calculate — results will appear here with the formula explained.
RDA for zinc is 11mg men, 8mg women 19+. This checks intake vs RDA.
Meat, shellfish, legumes are sources. Phytates in grains reduce absorption.
To use the Zinc Intake Calculator, enter age, sex, daily zinc (mg) above for an instant result with full breakdown and formula (RDA: M 11mg, F 8mg (19+); % = intake/RDA*100). Adjust values live to compare scenarios, then check the worked example and FAQs below for practical tips and costly mistakes to avoid.
