Zinc supplementation for babies can be obtained in two ways, one is through dietary modification and the other is through taking medication. If zinc supplementation is only needed for growth and development, it is best to supplement through the daily diet. Generally, you can give your child foods that are high in zinc, such as egg yolk, beef, pork liver, kelp, sea fish and shrimp. These foods contain high levels of zinc and can supplement your child’s daily needs. However, if your child already has low immunity, slow growth and loss of appetite, the zinc content in the body may be relatively low and you need to take your child to the hospital to check the trace elements and choose the medication to supplement according to the zinc deficiency.
