What is the effect of children taking cod liver oil?

Patient's question:

No

Doctor's answer:

Taking cod liver oil can prevent and treat rickets. When the child is around 18 months old, the development of the digestive organs gradually matures, and all the milk teeth have also erupted. At this time, the food the child eats is usually varied, and the sources of various nutrients are richer. The opportunity to receive sunlight increases, so cod liver oil is generally not needed to be taken.
