If calcium or zinc deficiency occurs in children, it is better to take the following medications: First, children can be given zinc licorice granules because zinc licorice granules are rich in zinc, which can effectively supplement the symptoms of zinc deficiency in children. Secondly, children should be given calcium gluconate oral solution, which can play a good role in correcting the symptoms of calcium deficiency in children. Once again, children should be given zinc and calcium oral solution, which is made of zinc and calcium together and can play a role in zinc and calcium supplementation. Lastly, children should be given vitamin D. Since the effect of calcium supplementation is poor when children are deficient in vitamin D, the effect of calcium supplementation will be significantly enhanced when children are given vitamin D and calcium together.
