Is it true that B vitamins are not suitable for children?

Children who are deficient in B vitamins can take B vitamins as needed, but children who are not deficient are not suitable for B vitamins and should take B vitamin supplements under the guidance of a doctor.
Common B vitamins include thiamin, riboflavin, niacin, folic acid and other micronutrients, which are essential micronutrients for the body. If a child is found to be deficient in B vitamins during a routine physical examination or nutritional level check, he or she may be prescribed a supplement of the appropriate B vitamin for the deficiency.
However, if the child is not deficient in B vitamins or if the daily dietary intake of B vitamins meets the body’s needs, unauthorized supplementation of B vitamins is not recommended, as excessive intake of B vitamins may cause metabolic stress on the liver or kidneys, which can lead to varying degrees of body damage.
Children should consult their physician before taking B vitamin supplements, and should be cautious not to take unauthorized medications.
