Should I give my child vitamins or supplements?

Most healthy children who eat a reasonably varied diet do not need a daily multivitamin. However, some children may benefit: very picky eaters, children on restricted diets (vegan, dairy-free), children with chronic conditions that affect absorption, or those with limited sun exposure (vitamin D). If you do give a vitamin, choose one formulated for children and treat it as medicine — gummy vitamins look and taste like candy, and overdose is a real risk (especially iron and vitamin A). Store them out of reach. Vitamin D (600 IU daily) is the most commonly recommended supplement for children, especially in northern climates. Avoid megadoses of any vitamin, as more is not better and can be harmful. Consult your pediatrician before starting any supplement — they can check for actual deficiencies with a blood test.
