Children need zinc supplementation if they have the following characteristics: First, if they consume too little animal food. If the child usually eats mainly green vegetables and fruits and consumes significantly less meat food, this can cause zinc deficiency in children and should be treated with zinc supplementation in a timely manner. Second, children with chronic diarrhea. If a child has chronic diarrhea, a large amount of zinc is lost through the intestinal tract and should be supplemented in a timely manner. Zinc supplementation can also promote the repair of the intestinal mucosa. Again, if a child has chronic kidney disease, zinc should also be supplemented in a timely manner. Finally, if a child suffers from a large area of burns, which can cause excessive zinc loss, it is also important to give the child appropriate zinc supplementation, which can be done with zinc glycyrrhiza granules or zinc gluconate.
