Dietary zinc intake of subjects with a body weight at the 97.5th percentile of reference body weights (i.e., 79.4 kg for men and 68.1 kg for women).
3
The median body weight of 18- to 79-y-old women is based on measured body heights of 19,969 women in 13 European Union Member States and assuming a BMI (in kg/m2) of 22 (118). At this body weight, the physiologic zinc requirement is 2.9 mg/d.

The median body weight of 18- to 79-y-old men is based on measured body heights of 16,500 men in 13 European Union Member States and assuming a BMI of 22 (118).
