Question

Compared to children of the same age, my baby is shorter and has a poor appetite. Examination shows a deficiency in both calcium and zinc. I am worried about the effects of supplementing both at the same time. Which should be supplemented first? What are the reasons?

Answer

After a medical examination, it was found that the child is deficient in both calcium and zinc. Calcium and zinc should not be supplemented simultaneously, as calcium, being a macromolecule with strong activity, will compete with zinc for carrier proteins, affecting zinc absorption. It is recommended to first supplement zinc, then calcium, to promote bone cell differentiation and ensure effective calcium deposition.
