Maternal mineral supplements pose no risk to breastfed infants when taken in normal doses, although their use should be unnecessary unless the mother’s nutritional status indicates a mineral deficiency.
Sevelamer is used as a phosphate binder and has negligible absorption by the mother. It carries a theoretical risk of reducing maternal vitamin absorption and hence reducing vitamin levels, especially fat-soluble vitamins (A and D), in milk.
