Question
A parent has questions about vitamin supplementation for their four-year-old child, wondering whether supplementation is needed and for how long it should be continued.
Answer
The duration of vitamin supplementation can be divided into two stages: under one year and over one year. During the infancy stage, it can be taken long-term, primarily to supplement vitamins A and D. However, not everyone needs additional vitamin supplementation, as a balanced diet usually provides sufficient vitamins. Only in special cases, such as in hair loss patients, is it suitable to supplement vitamins B2 and B6. It is recommended to establish a correct concept and scientifically supplement vitamins, which is beneficial and harmless to health.
