Breastfeeding women
Zinc is possibly safe when you are consuming within the recommended amounts while you are breastfeeding. But zinc can be possibly harmful when you use it in high doses for a longer period. Those women who are older than 18 years must not consume more than 40 mg of zinc daily and women between the age group of 14 to 18 years must not consume more than 34 mg per day while breastfeeding.
