There are no data on the excretion of multivitamin with iron into human milk. Vitamins are naturally present in breast milk. Several reports suggest that iron supplementation during lactation does not significantly affect the total concentration of iron in human milk. Multivitamin with iron preparations are generally considered safe for the infant by most clinicians as long as doses do not exceed the recommended dietary allowance (RDA) for lactation designated for each active ingredient.
