Although zinc deficiency is rare in developed countries, elderly and pregnant individuals sometimes experience it, notes Mayo Clinic.

As of 2015, the recommended dietary allowance in supplement form is 8 milligrams daily for females age 19 and older, 11 milligrams for males 19 years old and older and pregnant women, and 12 milligrams daily for lactating women 19 and older.
