When zinc combines with certain foods it may not be absorbed into your body and it will do you no good. If you are taking zinc, the following foods should be avoided or taken 2 hours after you take zinc:
Phosphorus-containing foods such as milk or poultry
Whole-grain breads and cereals
Do not take zinc supplements and copper, iron, or phosphorus supplements at the same time. It is best to space doses of these products 2 hours apart, to get the full benefit from each dietary supplement.
