Key takeaways
- What matters is elemental iron, not tablet weight. Most adults need 60–120 mg of elemental iron a day to treat a confirmed deficiency.
- The free Anemia Mukt Bharat IFA tablet (60 mg iron + folic acid) from your PHC is bioequivalent to branded ferrous sulfate and is the right first choice for most women.
- Take iron with vitamin C (lemon, amla, orange) and away from tea, coffee, milk, calcium and antacids — this single habit can double absorption.
- Alternate-day or once-daily dosing often absorbs more total iron than three-times-a-day, except in pregnancy or severe deficiency where daily dosing is used.
- If oral iron is not tolerated or not working, IV iron (iron sucrose or ferric carboxymaltose) is safe, effective and often covered by Ayushman Bharat or insurance.
- Iron tablets are a leading cause of accidental child poisoning — lock them away, never call them 'sweets'.
Iron salts and bioavailability: what actually matters
Iron supplements are not all the same. They contain different chemical forms of iron (iron salts), with different amounts of usable iron per tablet, different absorption rates, and very different prices and side-effect profiles.
The number that matters is elemental iron — the actual iron available for absorption, not the total tablet weight. A 200 mg ferrous sulfate tablet provides about 65 mg of elemental iron (roughly 33 percent). A 300 mg ferrous fumarate tablet provides about 100 mg (also ~33 percent). A 300 mg ferrous gluconate tablet provides only about 35 mg (~12 percent). Always compare products by elemental iron, not by the bigger-looking number on the box.
Ferrous salts (sulfate, fumarate, gluconate) are the most studied, cheapest and most effective options. They release iron in the stomach, which is then absorbed in the duodenum. In a deficient woman, about 10–20 percent of a 60–100 mg dose is absorbed. Side effects — nausea, constipation, metallic taste, dark stools — come from free iron irritating the gut.
Iron polymaltose complex (IPC) binds iron to a polymaltose carrier and is absorbed by a gentler route. Efficacy is similar to ferrous salts but many women tolerate it better, at a slightly higher cost (around Rs 150–300 a month). Brands include Orofer XT and Tonoferon.
Carbonyl iron is fine elemental iron absorbed gradually, which means fewer gut side effects but slower correction of deficiency. Iron amino-acid chelate (bisglycinate) binds iron to the amino acid glycine for improved tolerance; it is the basis of many 'gentle' formulations such as Florafer (around Rs 200–500 a month). Heme iron polypeptide and sucrosomial iron are very well tolerated but expensive and only patchily available in India.
Absorption is easy to sabotage. An empty stomach gives 2–3 times higher absorption than a full one. Vitamin C (50–100 mg with the dose) can boost it 2–4 fold. Tea and coffee within an hour cut absorption by 60–80 percent. Calcium (milk, dairy, supplements), antacids, and acid-reducing PPIs (omeprazole, pantoprazole) all reduce it. Iron also blocks the absorption of thyroxine and several antibiotics, so these must be separated by a few hours.
Newer dosing evidence: the old habit of three tablets a day is no longer ideal. Each iron dose raises hepcidin (an iron-blocking hormone) for about 24 hours, which limits the next dose. So alternate-day or single daily dosing often absorbs more total iron for non-pregnant women. Pregnancy and severe deficiency still usually use daily dosing because correction is time-sensitive.
The Indian brand guide: what to ask your pharmacist
Free government options (first choice for most women): the Anemia Mukt Bharat IFA tablet — 60 mg elemental iron + 500 mcg folic acid — is free at every PHC, Anganwadi, ASHA and government school, including a weekly version for adolescent girls under the WIFS programme. Jan Aushadhi pharmacies sell generic ferrous sulfate 200 mg (65 mg iron) for around Rs 15–50 per 100 tablets. For anyone watching cost, these should be tried first.
Ferrous sulfate / fumarate branded tablets (cheap, effective, moderate tolerability): common names include Fefol (ferrous sulfate + folic acid), Livogen (ferrous fumarate + folic acid), Autrin, Iberet Folic 500 and Hemfer, typically Rs 50–200 a strip. These are the everyday workhorses prescribed across India.
Iron polymaltose tablets (better tolerated, mid-price): Orofer XT, Tonoferon, Globac-Z and Maltofer, roughly Rs 100–500 a strip. A sensible switch if ferrous salts upset your stomach.
Liquids and syrups (for those who cannot swallow tablets or have severe nausea): Tot'hema (ferrous gluconate liquid, around Rs 200–400 a bottle) and Dexorange syrup (around Rs 100–250). Also used in children and adolescents.
Chelated and premium options: Florafer and other iron-bisglycinate products (around Rs 250–500) for a gentler tablet, plus women's multivitamins such as Femiplex and Centrum Women that combine modest iron (18–35 mg) with B vitamins. Convenient, but check the elemental iron is enough to treat true deficiency.
A simple hierarchy for a typical Indian woman: (1) free Anemia Mukt Bharat IFA from the PHC; (2) Jan Aushadhi ferrous sulfate; (3) a branded ferrous salt like Fefol or Livogen if you prefer; (4) iron polymaltose (Orofer XT) if ferrous salts cause side effects; (5) a liquid (Tot'hema, Dexorange) if you cannot swallow tablets; (6) iron bisglycinate (Florafer) as a premium gentle option; (7) IV iron when oral genuinely fails or a specific medical reason calls for it. The free PHC tablet is bioequivalent to the branded ones and deserves the first try.
If your deficiency comes from heavy periods, treating the bleeding matters as much as the iron — read more on heavy menstrual bleeding and its full treatment ladder. And if a vegetarian diet is part of the picture, see the non-pregnancy iron deficiency guide for Indian women.
How to take iron supplements correctly
Timing. Absorption is best on an empty stomach (1 hour before or 2 hours after food), but that also causes the most nausea. A practical compromise is a light snack — a banana, a biscuit, a small fruit. For ongoing supplementation, alternate-day dosing may absorb more total iron than daily dosing; pregnancy and severe deficiency stick to daily for faster correction.
The vitamin C trick. Taking iron with 50–200 mg of vitamin C can boost absorption 2–4 fold. Easy options: lemon water with the tablet, a glass of orange or amla juice, an orange afterwards, or a vitamin C tablet (Limcee, Celin). One amla provides around 600 mg of vitamin C. This is the single most powerful, free way to make any iron supplement work better.
What to keep away from your iron. Tea and coffee within an hour. Milk, paneer, curd and cheese within 2 hours. Antacids (Eno, Digene) and PPIs (Pan, Razo, Omez), which reduce the stomach acid iron needs. Multivitamins that contain calcium or magnesium.
Drug interactions worth knowing. Iron binds thyroxine (Thyronorm), so separate by about 4 hours; the same applies to quinolone antibiotics (ciprofloxacin, norfloxacin), tetracyclines (doxycycline) and bisphosphonates. If you take a regular medicine, ask your pharmacist about spacing.
Side-effect management. Nausea is the commonest complaint — take with a small snack, split a higher dose into morning and evening, try at bedtime, switch to iron polymaltose or a liquid, or move to alternate-day dosing. Most women settle within 2–4 weeks. Constipation responds to more water (2.5–3 litres), fibre, isabgol (psyllium husk) at bedtime, a daily walk, and gentle lactulose (Duphalac) if needed — avoid stimulant laxatives for long-term use. Metallic taste fades with time and is masked by vitamin C drinks.
Dark or black stools are normal and not bleeding. They are simply unabsorbed iron passing through. True intestinal bleeding looks different — sticky, tarry, foul-smelling, often with weakness or dizziness — and needs medical review. Liquid iron can stain teeth, so rinse with water or use a straw, and brush about 30 minutes later.
Store safely. Keep iron in a cool, dry place in its original pack, away from the bathroom — and well out of children's reach (see the safety section below).
Dose selection: treatment vs prevention vs pregnancy
Treating confirmed deficiency (ferritin below 30 mcg/L, or anaemia): the standard adult dose is 60–120 mg of elemental iron daily for 3–6 months, then re-test ferritin and haemoglobin. Mild cases often need one branded tablet a day; moderate-to-severe cases may need two (split morning and evening).
Prevention in non-pregnant women: the Anemia Mukt Bharat approach uses one weekly 60 mg tablet, which is enough for women who are not deficient and have normal periods. Adolescent girls receive the same weekly dose through the WIFS programme.
Pregnancy: from the second trimester (after 12–14 weeks), the standard is 60 mg elemental iron + 500 mcg folic acid daily for at least 180 days, continuing through lactation, with higher doses if anaemia is present. First-trimester care usually focuses on folic acid; for couples planning ahead, see folic acid before conception.
Postpartum: delivery blood loss (300–500 mL for a vaginal birth, more for a caesarean) plus breastfeeding deplete stores, so continue daily iron for at least 6 months — longer if you were anaemic in pregnancy. Iron also helps the energy and recovery covered in postpartum nutrition.
Heavy periods: take 60–120 mg of elemental iron daily while the underlying bleeding is assessed and treated, and continue for at least 6 months after it settles.
Preconception: aim to optimise iron in the 3–6 months before conception. Check ferritin and supplement if it is below about 50 mcg/L, alongside folic acid.
Severe deficiency or urgent correction — haemoglobin under 7 g/dL, third-trimester pregnancy with low haemoglobin, before major surgery, after bariatric surgery, or with inflammatory bowel disease — is where IV iron is preferred for speed and reliability.
Duration: keep taking oral iron for about 3 months after haemoglobin normalises, to refill the stores ferritin measures. A full course is usually 4–6 months, with annual re-checks for women who keep losing iron.
IV iron: iron sucrose, ferric carboxymaltose and isomaltoside
Intravenous iron has transformed care for women who cannot tolerate or absorb oral iron, or who need rapid correction. The main options in India are iron sucrose (the workhorse), ferric carboxymaltose (the convenient single-dose option) and iron isomaltoside (a newer alternative).
When IV iron is chosen over oral: intolerance despite trying several formulations; severe anaemia needing fast correction; third-trimester pregnancy with low haemoglobin; correction before major surgery; failure of oral iron despite good compliance (a clue to malabsorption); inflammatory bowel disease; after bariatric surgery; chronic kidney disease on erythropoietin; heart failure with iron deficiency; and severe postpartum anaemia. Anaemia in late pregnancy is a common reason — see anaemia in pregnancy and the Anemia Mukt Bharat protocol.
Iron sucrose (Resofer, Ferium, Sucrofer and others) costs around Rs 800–2,000 a dose. It is given as 100–200 mg per session, usually over several sessions across 1–3 weeks to deliver the full deficit. Each session takes 30–60 minutes with a short observation period afterwards. It is well tolerated; serious reactions are very rare.
Ferric carboxymaltose (Ferinject, Encicarb FCM and others) costs around Rs 4,000–8,000 a dose but delivers 1,000–1,500 mg in a single 15–60 minute infusion — often the whole deficit in one or two visits, with haemoglobin rising 2–3 g/dL within four weeks. It can cause transient low phosphate, usually without symptoms.
Iron isomaltoside (Monofer) is a newer single-dose option (around Rs 6,000–12,000), available mainly in specialty centres.
What an infusion is actually like: you book a slot at a hospital day-care or infusion centre, have your vitals checked, a cannula placed, the infusion run over 15–60 minutes, then 15–30 minutes of observation. Most women go home the same day; some hospitals offer home infusions for elderly or less mobile patients.
Cost and access: total iron-sucrose courses run roughly Rs 4,000–12,000; ferric carboxymaltose is a single Rs 4,000–8,000 dose, plus day-care charges. Ayushman Bharat PMJAY covers IV iron for eligible families, CGHS/ECHS/ESI for government and insured employees, and most health insurance when there is a documented indication. Government tertiary hospitals (AIIMS, PGI, JIPMER, CMC, KEM) provide it free or at minimal cost, and most private chains offer it too.
After IV iron: re-check haemoglobin and ferritin at 4–6 weeks, keep a low maintenance oral dose if appropriate, and treat the underlying cause — heavy periods, gut bleeding or malabsorption — so the deficiency does not simply return.
Pregnancy and postpartum: special considerations
Pregnancy roughly doubles iron needs (about 35 mg a day) to build the mother's expanded blood volume, the placenta and the baby — a total cost of around 1,000 mg. Diet alone rarely covers this in Indian women, which is why universal supplementation matters. Pairing tablets with the right foods helps, as set out in iron-rich foods in Indian pregnancy.
Antenatal supplementation follows the Anemia Mukt Bharat protocol: 60 mg elemental iron + 500 mcg folic acid daily from the second trimester for at least 180 days, free at every PHC and Anganwadi. Side-effect counselling is key, because compliance is the real bottleneck.
First-trimester iron is debated — routine iron is not standard before 12–14 weeks because it can worsen morning sickness, while folic acid is universal. Severe anaemia at booking may need earlier treatment, often IV iron to avoid nausea.
Treating anaemia in pregnancy: mild (Hb 10–11) usually responds to standard daily iron; moderate (Hb 8–10) needs higher doses with monthly monitoring; severe (Hb under 8, or under 9 in the third trimester) is an indication for IV iron, and sometimes transfusion. IV iron sucrose and ferric carboxymaltose are both used safely from the second trimester.
Postpartum and lactation: continue daily iron for at least 6 months after delivery, longer if antenatal anaemia was significant, with a haemoglobin check around 6 weeks. Adequate iron supports energy, mood and breastfeeding; low iron is also one of the contributors to postpartum hair loss in Indian women.
Birth spacing: pregnancies less than 24 months apart do not let iron stores recover, so WHO and India's RMNCH+A guidance recommend at least 24 months between births, with contraceptive counselling at the 6-week visit.
Why it matters: good iron status lowers the risk of low birth weight, preterm birth and postpartum haemorrhage. Untreated severe anaemia raises the risk of haemorrhage and infection for the mother and growth restriction for the baby — anaemia contributes to a significant share of maternal deaths in India, which is exactly why the free programme exists.
Safety: iron poisoning in children and adults
Iron is one of the leading causes of accidental child-poisoning deaths in India and worldwide — and it is under-recognised. Antenatal and Anemia Mukt Bharat programmes have put iron tablets into millions of homes where curious toddlers can reach them.
Why a few tablets are dangerous. Around 20–60 mg of elemental iron per kg can cause moderate toxicity, and above 60 mg/kg can be severe or fatal. A 12 kg toddler can be seriously poisoned by 240–720 mg — as little as 4–12 adult tablets, easily swallowed from a bottle left within reach. Sweet coatings make them look like candy.
How poisoning unfolds: vomiting (sometimes bloody), diarrhoea and abdominal pain within the first 6 hours; a deceptive 'recovery' phase; then, 12–48 hours in, acidosis, shock and liver injury; with gut scarring possible weeks later. Apparent improvement does not mean the child is safe.
Prevention is everything. Store iron in its original child-resistant container, in a locked cabinet or high shelf — never in a bedside drawer, handbag or low cupboard. Brief everyone in the home, including grandparents and helpers. Never call iron tablets 'sweets'. Dispose of leftover tablets safely once a course is finished.
If you suspect a child has swallowed iron, do not wait for symptoms. Take them straight to the nearest emergency with the strip or bottle, and call 102 or 108 if they are unwell or far from a hospital. Do not induce vomiting unless told to. The AIIMS National Poison Information Centre runs a 24/7 helpline on 011-26593677 / 1800-116-117.
In adults, standard prescribed doses have a wide safety margin and do not cause chronic iron overload in a deficient woman. The risk is a large deliberate or accidental overdose, which needs the same emergency care. Also avoid stacking multiple iron-containing products (an 'iron tonic' plus IFA plus a multivitamin) — add up the elemental iron so you are not unknowingly over-dosing.
For joint families where several women may be on iron at once, a single locked family medicine cabinet is the simplest way to keep all tablets away from children.
Monitoring response and when to switch
Re-check at 3 months. With effective, well-absorbed iron, haemoglobin should rise about 1–2 g/dL per month. Ferritin recovers more slowly and may take 4–6 months to climb back above 50 mcg/L from a depleted state.
Signs it is working: rising haemoglobin and ferritin, more energy and exercise tolerance, and improving hair quality from around 2–3 months.
If there is no response, look for a reason before blaming the iron: poor compliance (the commonest cause), wrong timing (with tea, coffee, milk or calcium), interacting drugs (PPIs, antacids, thyroxine), ongoing blood loss exceeding intake, malabsorption (coeliac disease, IBD, post-bariatric, atrophic gastritis), inflammation, or a different diagnosis altogether — such as a B12 deficiency, folate deficiency or thalassaemia trait.
Useful tests for non-response include a stool occult-blood test, coeliac serology, B12 and folate levels, thyroid function, an inflammatory marker (CRP), and haemoglobin electrophoresis if the cells are small without true iron deficiency. Upper GI endoscopy or colonoscopy is indicated when bleeding is suspected.
When to switch the oral formulation: persistent intolerable side effects after 2–4 weeks despite good timing. A sensible sequence is ferrous sulfate → iron polymaltose (Orofer XT) → liquid (Tot'hema, Dexorange) → iron bisglycinate (Florafer) → IV iron if all oral options fail.
When to investigate the cause rather than just treat: any iron deficiency in a postmenopausal woman (always exclude gut cancer), recurrent deficiency despite treatment, deficiency with weight loss or abdominal symptoms, or a family history of bowel cancer.
Long-term and at-risk women. After correction, some women need ongoing maintenance — daily low-dose, weekly, or alternate-day — depending on continued blood loss and diet. Women who are pregnant, breastfeeding, vegetarian, athletes, frequent blood donors, or who have heavy periods benefit from an annual haemoglobin and ferritin check to catch depletion early.
Special situations: vegetarians, PCOS, surgery, CKD and IBD
Vegetarians have lower iron stores and a higher deficiency risk, so lifelong attention helps: an iron-rich diet (ragi, kala chana, soybean, jaggery, sesame, drumstick leaves) paired with vitamin C, the weekly AMB tablet as a baseline, annual ferritin checks, and treatment doses when deficiency develops. Vegan women usually also need B12. Adequate protein supports recovery too — see protein needs for Indian vegetarian women.
PCOS often brings iron deficiency through heavy or irregular periods, so the bleeding needs managing alongside the iron — read about PCOS treatment options in India. PCOS frequently coexists with vitamin D and B12 deficiency, which are worth checking together; vitamin D deficiency is very common in Indian women.
After bariatric surgery, iron absorption drops sharply because the duodenum is bypassed and stomach acid falls; many women need periodic IV iron and lifelong monitoring.
Inflammatory bowel disease (Crohn's, ulcerative colitis) makes oral iron poorly absorbed and can worsen gut inflammation, so IV iron is preferred while the disease itself is controlled.
Chronic kidney disease mixes iron deficiency with EPO-resistant anaemia and inflammation, and usually needs IV iron alongside erythropoiesis-stimulating agents, with a higher ferritin target than usual and nephrology input.
Heart failure with iron deficiency — even without anaemia — does better with IV ferric carboxymaltose, which improves exercise capacity and reduces hospital stays.
Female athletes lose iron through foot-strike, sweat and gut losses and often need supplementation even when not anaemic, with an annual ferritin target above about 50 mcg/L. Regular blood donors lose 200–250 mg of iron per donation and benefit from supplementation between donations. Elderly women often have mixed iron, B12, folate and chronic-disease anaemia and may tolerate IV iron better than oral.
Iron deficiency is also a major, treatable cause of restless legs syndrome in Indian women — worth checking ferritin if your legs are restless at night.

Iron supplement myths in India, corrected
Myth: branded iron is more effective than the free PHC tablet
- Fact: the Anemia Mukt Bharat IFA tablet (ferrous sulfate ~65 mg elemental iron + folic acid) is bioequivalent to most branded ferrous sulfate products.
- Fact: AMB tablets are quality-controlled to Indian Pharmacopoeia standards through the Central Drugs Standard Control Organisation.
- Fact: branded products may have nicer packaging and marketing — but the same active ingredient.
- Fact: iron polymaltose (Orofer XT) may be gentler than ferrous sulfate, but it is not 'stronger' in iron delivered.
- Fact: for most women, the free AMB tablet is the right first choice; a branded alternative makes sense only if you cannot tolerate it.
Myth: IV iron is dangerous and only for emergencies
- Fact: modern IV iron (iron sucrose, ferric carboxymaltose) is very safe, with serious-reaction rates well under 0.01 percent.
- Fact: it is used routinely in pregnancy, postpartum, before surgery, and in kidney disease and IBD — not only in emergencies.
- Fact: a single ferric carboxymaltose infusion can replace months of oral iron with better tolerability.
- Fact: it is often covered by Ayushman Bharat PMJAY and most health insurance.
- Fact: if oral iron is not tolerated or not working, ask your doctor about IV iron — it is an excellent option.
Myth: iron tablets must be taken on a completely empty stomach
- Fact: an empty stomach absorbs 2–3 times more, but if it makes you nauseous, taking it with a light snack is worth the small trade-off for being able to continue.
- Fact: the biggest driver of success is taking the tablet consistently — a perfectly timed tablet you cannot tolerate fails worse than a slightly less-ideal one you take every day.
- Fact: pair it with vitamin C (lemon water, orange) regardless of meal timing to boost absorption.
- Fact: still avoid tea, coffee, milk, calcium and antacids within 2 hours of the dose.
- Fact: find the routine that works for you and keep it up.
Myth: it is fine to keep all the family's medicines together
- Fact: iron tablets are a leading cause of child-poisoning deaths — store them separately and securely.
- Fact: even 4–12 adult tablets can seriously poison a 12 kg toddler.
- Fact: original child-resistant packaging, a locked cabinet and a high shelf are essential.
- Fact: never call iron tablets 'candy' or 'sweet', and brief every adult in the home.
- Fact: keep the AIIMS National Poison Information Centre number handy — 011-26593677 / 1800-116-117.
Frequently asked questions
Which iron supplement is best for Indian women?
For most women, the free Anemia Mukt Bharat IFA tablet from a PHC or a Jan Aushadhi generic ferrous sulfate is the best value and works as well as branded options. If ferrous salts upset your stomach, switch to iron polymaltose (Orofer XT) or a liquid (Tot'hema). The 'best' supplement is the one you can take consistently.
How long does it take for iron tablets to work?
Energy often improves within 2–4 weeks, and haemoglobin usually rises about 1–2 g/dL per month. Ferritin (your iron stores) recovers more slowly, so continue iron for about 3 months after haemoglobin normalises — a full course is usually 4–6 months. Always re-test before stopping.
Why are my stools black after starting iron — is it bleeding?
Black stools are normal and expected with iron — they are simply unabsorbed iron, not blood. True intestinal bleeding looks different: sticky, tarry and foul-smelling, often with weakness or dizziness. If you are genuinely unsure, a stool occult-blood test can tell the difference.
Can I take iron with milk or tea?
No — both reduce absorption. Tea and coffee (tannins) cut it by 60–80 percent, and milk and dairy (calcium) compete with iron. Keep them at least 1–2 hours away from your dose, and instead take iron with vitamin C such as lemon water or amla.
When do I need IV iron instead of tablets?
IV iron is considered when oral iron is not tolerated despite trying several formulations, when it is not working despite good compliance, when anaemia is severe or correction is urgent (such as late pregnancy or before surgery), or in conditions like IBD, kidney disease or after bariatric surgery. It is safe and often covered by insurance or Ayushman Bharat.
Is it safe to take iron during pregnancy?
Yes — iron is recommended for almost all pregnant women in India, usually 60 mg elemental iron plus folic acid daily from the second trimester. It lowers the risk of low birth weight, preterm birth and postpartum haemorrhage. If tablets cause severe nausea or anaemia is significant, your doctor may use IV iron from the second trimester.
