There are many foods that supplement vitamin A. If a child is deficient in vitamin A, parents should correct their child's picky eating habits. Animal livers, cod liver oil, egg yolks, and dairy foods are rich in vitamin A. In addition, liver and some soy foods also contain vitamins. If the intake is small or there is not enough vitamin content in the food, you can take vitamin A medicine to improve the vitamin deficiency. In addition, carotene and some fruits also contain appropriate amounts of vitamin A. Children who are deficient in vitamins should still pay attention to a balanced diet and eat more vegetables and fruits. In addition, lack of vitamin A can cause night blindness and vision loss in some children, so attention must be paid to this at home. How do children supplement vitamin A? Vitamin A can actually be taken from most foods, but children who are picky eaters, malnourished or have poor absorption can take vitamin A medicines to supplement, which will have a more obvious effect. In addition, if you choose medicines, you can choose OTC oral medicines, which are very helpful to the body.
