Iron deficiency anaemia is India's most prevalent — and most preventable — nutritional crisis. According to NFHS-5 (2019–21), 57% of Indian children under 5, 67% of pregnant women, and 53% of non-pregnant women of reproductive age are anaemic. Despite decades of government supplementation programs, the numbers have barely moved. The reason? Most people don't understand how iron actually works — what blocks absorption, what enhances it, and what type of iron supplement actually gets absorbed.
This guide covers everything you need to know to address iron deficiency effectively in the Indian context.
Haem iron (from animal sources) is absorbed at 15–35%; non-haem iron (plant sources) at only 2–20%. Combining iron-rich plant foods with vitamin C dramatically increases absorption. Iron supplements work — but choosing the right form (ferrous bisglycinate over ferrous sulphate) determines tolerability and effectiveness.
How to Recognise Iron Deficiency
Iron deficiency progresses through stages — you can be iron-depleted before becoming clinically anaemic. Early signs include: persistent fatigue and weakness (even with adequate sleep), pale inner eyelids and pale nail beds, frequent headaches or dizziness, cold hands and feet, brittle nails that chip easily, hair loss (telogen effluvium), shortness of breath on mild exertion, poor concentration and brain fog, unusual food cravings (especially ice or clay — called pica), and restless leg syndrome at night.
The only definitive diagnosis is blood work — ask your doctor for CBC (complete blood count), serum ferritin, and TIBC. Critically: serum ferritin below 30ng/mL indicates depleted iron stores even if haemoglobin is normal. Most Indian women walk around with ferritin in the 10–20 range and feel chronically exhausted — this is treatable.
Why India's Iron Deficiency Is So Persistent
Several factors make iron deficiency uniquely challenging in India. Vegetarian diets: the majority of Indians consume predominantly plant-based diets — non-haem iron from plants is inherently less bioavailable than haem iron from meat. Phytates: whole grains and legumes (dal, rice, wheat) contain phytic acid which binds to iron in the gut and blocks absorption — the very staples of the Indian diet are iron absorption inhibitors. Calcium timing: dairy consumed at the same meal as iron-rich foods (common in Indian meals — curd with dal-rice) inhibits iron absorption significantly. Tea consumption: tannins in chai (particularly strong morning tea) dramatically reduce iron absorption — drinking tea within 1 hour of meals is one of India's biggest hidden contributors to anaemia. Parasitic infections: hookworm and other intestinal parasites cause chronic blood loss and are still endemic in parts of rural India.
Best Iron-Rich Indian Foods
Animal Sources (Haem Iron — Highest Absorption)
For non-vegetarians: chicken liver (13mg iron per 100g — the single richest iron food available in India), mutton (3mg/100g), chicken (1.3mg/100g), eggs (1.8mg/100g — not as high as commonly believed, but the haem form is well-absorbed), and fish (especially sardines and mackerel — 3–4mg/100g).
Plant Sources (Non-Haem Iron — Enhance with Vitamin C)
The richest plant sources in Indian cooking: horse gram (kulthi dal) — 7mg/100g, the highest iron content of any Indian legume; sesame seeds (til) — 14.6mg/100g, exceptionally iron-dense; pumpkin seeds (8.8mg/100g); dried apricots — 6mg/100g (popular as khumani); kala chana (black chickpeas) — 6.6mg/100g; rajma — 5mg/100g; methi (fenugreek) leaves — 1.9mg/100g fresh; amaranth (rajgira) leaves — 3mg/100g; jaggery (gud) — 11mg/100g (but eat in moderation given sugar content); lotus seeds (makhana) — 1.4mg/100g; and dried figs (anjeer) — 2mg/100g.
How to Maximise Iron Absorption From Food
The 3 golden rules for iron absorption: (1) Pair non-haem iron foods with vitamin C: eating a small amla (Indian gooseberry — 600mg vit C/100g), lemon squeezed over dal, or tomatoes alongside iron-rich food converts non-haem iron to a more absorbable form and can increase absorption 2–3-fold. (2) Avoid iron blockers at the same meal: tea, coffee, calcium-rich dairy, and high-phytate foods eaten simultaneously reduce iron absorption. Have chai at least 1 hour before or after meals. (3) Soak and sprout legumes: soaking dal overnight and cooking it reduces phytate content by 50–70%, dramatically improving iron bioavailability. Sprouted moong is one of the best bioavailable iron sources in vegetarian diets.
Iron Supplements: Which Form Is Best?
Not all iron supplements are created equal. Ferrous sulphate (the cheapest and most commonly prescribed form in government programs) has 20% absorption but causes significant GI side effects — constipation, nausea, and dark stools — which lead to poor compliance. Ferrous bisglycinate (iron glycinate) is chelated to glycine, giving it 4–5x better absorption than ferrous sulphate with minimal side effects. This is the gold standard for iron supplementation if compliance is a concern. Ferric pyrophosphate (micronised, dispersible form) — increasingly used in food fortification and newer supplements, good GI tolerability. Liposomal iron — encapsulated in lipid for protection and absorption, minimal GI side effects, ideal for those with very sensitive stomachs.
Dosing: therapeutic correction of anaemia typically requires 100–200mg elemental iron per day for 3–6 months. Note: elemental iron content differs from the total compound dose. For example, ferrous sulphate 325mg contains only 65mg elemental iron. Take iron supplements on an empty stomach with water and a squeeze of lemon — absorption is significantly better than with food.
Top Iron Supplements Available in India (2026)
Evidence-backed options: Feronia XT Syrup (ferrous ascorbate + folic acid, widely prescribed), Zyntra / Orofer XT (ferrous bisglycinate — excellent for those with constipation on standard iron), Wellbeing Nutrition Iron+ supplement (ferrous bisglycinate chelate, plant-derived, good tolerability), Nature's Velvet Iron Bisglycinate (cost-effective chelated form), and Sunova Bioslim Iron (for women preferring food-based formulations). Always pair iron supplements with 500mg vitamin C for maximal absorption.
