之前专门发邮件问过他们公司,他们是这么说的,What you are describing sounds very much like the mineral premix we add to the toddler products.
This mineral premix is not added to the infant 1 and 2 formulas.The mineral pre-mix is the mixture of vitamins and other nutritional ingredients we add to the base powders of our product, all being suitable
for the different ages and stages of growing babies and toddles.
