Question
My son is 6.5 years old, 1.2 meters tall, and weighs 21.5 kilograms. He has a poor appetite, and the examination found that he lacks calcium and needs supplementation.
Answer
It is recommended to supplement iron from food sources, such as eating more animal liver and other iron-rich foods. Usually, heme iron in meats and internal organs is more easily absorbed by the body and is beneficial for iron digestion. Additionally, getting more sun exposure can help improve absorption rates and enhance resistance.
