Overview

• Studies cited in the latest coverage find little proof that routine supplements improve health or prevent illness in otherwise healthy children.
• Fat‑soluble vitamins such as A, D, E and K can accumulate to toxic levels, with overdoses from some vitamins reported as severe and potentially fatal.
• Many children’s products are sweetened or flavored, introducing added sugars and artificial ingredients that can undermine healthy eating habits.
• Common staples like breakfast cereals, milk and bread are often fortified, helping even selective eaters obtain key nutrients.
• Supplementation is appropriate for diagnosed deficiencies or specific medical conditions, which should be managed under guidance from a GP or pediatric dietitian.
