                                While globally, iron and vitamin D are two of the most common nutrient deficiencies in children, the question of 'What's the most important vitamin for kids?' is fundamentally flawed. A child's growth and development rely on a complex interplay of many essential vitamins and minerals, not just one single 'super' nutrient.
