At what age should a one-year-old baby take calcium, iron, and zinc?

Patient's question:

No

Doctor's answer:

Generally, symptoms such as poor appetite, geographic tongue, short stature, low immunity, poor intelligence, and yellow, thin hair may indicate a need for zinc supplementation. For children confirmed to be zinc deficient, zinc supplements can be administered. Zinc preparations include zinc gluconate, zinc sulfate, zinc glycyrrhizinate, and zinc acetate, etc.
