Iron deficiency in children: signs, testing and treatment

Why is iron so critical for children?

Iron is an essential mineral required to produce haemoglobin, the protein inside red blood cells that transports oxygen from the lungs to every organ in the body, including the growing brain. During childhood and adolescence, rapid blood volume expansion and muscle growth demand a constant supply of dietary iron.

Common signs of iron deficiency in children

Mild iron deficiency often goes unnoticed in early stages. As body iron stores fall, parents may notice:

• Unusual fatigue and low stamina: Getting tired quickly during playground games or sports.
• Paleness: Noticeable in the conjunctiva (inner lower eyelids), lips, tongue, or nail beds.
• Decreased attention and memory: Difficulty focusing during schoolwork or frequent irritability.
• Poor appetite: Paradoxically, low iron often dampens appetite, creating a vicious cycle where the child refuses food.
• Pica: Craving non-food items such as ice, chalk, clay, or raw rice.
• Frequent minor infections: Due to suboptimal immune cell responses.

How is iron deficiency tested?

Never guess or start high-dose iron without diagnostic confirmation. A paediatrician will typically order:

• Complete Blood Count (CBC / Hemogram): Measures haemoglobin, haematocrit, and red cell indices (MCV and MCH, which show small, pale red blood cells in iron deficiency).
• Serum Ferritin: The gold standard test for measuring the body’s stored iron reserves. A low ferritin confirms iron depletion even before haemoglobin drops.

Dietary sources of iron in Indian households

Iron in food comes in two forms: heme iron (found in poultry, meat, and fish; highly absorbable) and non-heme iron (found in plant foods). In vegetarian Indian diets, non-heme iron can be boosted by serving:

• Lentils, chickpeas (chana), rajma, and sprouted beans.
• Dark leafy greens such as spinach (palak), methi, and amaranth.
• Jaggery (gur), dates, raisins, and dried figs.
• Whole grains such as bajra, ragi, and fortified flours.

Absorption tip: Always pair plant iron with vitamin C (lemon juice on dal, sliced tomatoes, or an orange) and keep milk or tea away from meals, as calcium and tannins hinder iron absorption.

When are iron supplements needed?

When a blood test confirms low iron reserves or anaemia, dietary changes alone are rarely fast enough to rebuild depleted marrow stores. A paediatrician will prescribe an iron supplement for 2 to 3 months.

For children who refuse traditional bitter iron syrups, Chubears Iron Gummies provide 13 mg of elemental iron per 2 gummies as ferric pyrophosphate (SunActive® Fe), a gentle form with zero metallic taste and no liquid tooth staining.
