Problems in children have not been reported with intake of normal daily recommended amounts.
Problems in older adults have not been reported with intake of normal daily recommended amounts. There is some evidence that the elderly may be at risk of becoming deficient in zinc due to poor food selection, decreased absorption of zinc by the body, or medicines that decrease absorption of zinc or increase loss of zinc from the body.
It is especially important that you are receiving enough vitamins and minerals when you become pregnant and that you continue to receive the right amount of vitamins and minerals throughout your pregnancy. The healthy growth and development of the fetus depend on a steady supply of nutrients from the mother. There is evidence that low blood levels of zinc may lead to problems in pregnancy or defects in the baby. However, taking large amounts of a dietary supplement in pregnancy may be harmful to the mother and/or fetus and should be avoided.
It is important that you receive the right amounts of vitamins and minerals so that your baby will also get the vitamins and minerals needed to grow properly. However, taking large amounts of a dietary supplement while breast-feeding may be harmful to the mother and/or baby and should be avoided.
