Micronutrients — vitamins and minerals like iron, vitamin D, B12, and zinc — are essential for a child’s growth, energy, mood, immunity, and concentration. A deficiency can quietly affect appetite, skin and hair, the gut, and overall wellbeing.

Common signs that may prompt a check include persistent tiredness, poor appetite, frequent infections, pale skin, or slow growth. In children, iron and vitamin D deficiencies are among the most common, especially with limited or picky diets.

The first-line approach is always a balanced, varied diet rich in whole foods. Where a deficiency is suspected, a doctor can assess your child and arrange appropriate testing if needed, then advise on diet changes or supplements. Supplements should only be given on medical advice, as too much of some nutrients can be harmful.

If you’re concerned your child may have a nutrient deficiency, a pediatric consultation can assess their growth and symptoms.
