Aluminum phosphate is a chemical compound found in womenâ€™ breast milk at low level concentrations ranging from 0.0092 to 0.049 mg/L. Only a small amount of this aluminum will enter the infantâ€™s body through breastfeeding. However, the Center for Disease Control (CDC) noted that in soy-based and milk-based infant formulas the concentrations range from 0.46â€“0.93 mg/L and 0.058â€“0.15 mg/L respectively.1 Researchers suggested that the concentrations of aluminum phosphate in infant formulas were too high, and could cause problems, including brain and bone diseases in infant with kidney problems.1,2 Thus, considering breastfeeding may be a healthier choice. Despite these remarks, the FDA considers aluminum phosphate used as food additives safe. Sources: 1.
