Iron and folic acid tablets: Uses, types, and who needs them

More than half of Indian women of reproductive age, 57%, are anaemic, and the figure is higher still in pregnancy and adolescence (National Family Health Survey-5, 2019-21). That single statistic is why India runs one of the world's largest supplementation programmes around a single combination: iron and folic acid, given together rather than separately. This piece explains why the two are paired, how much you actually need, and who typically ends up taking one.

What is an iron and folic acid (IFA) tablet?

An iron and folic acid (IFA) tablet combines a source of elemental iron with folic acid in a single dose, rather than requiring two separate supplements. It is the standard combination used in India's public health anaemia programmes and is also widely sold over the counter and by prescription.

The logic behind combining them is nutritional, not marketing: both nutrients are needed to make healthy red blood cells, and a shortfall in either one can show up as anaemia, tiredness, and reduced work or study capacity. Treating just one when both are low is a common reason supplementation doesn't fully resolve someone's anaemia.

Worth knowing: the NIH Office of Dietary Supplements notes that folate "is needed for the production and maintenance of new cells," a role that sits alongside iron's role in haemoglobin, the oxygen-carrying part of red blood cells (NIH ODS, as of July 2026). Together, not separately, is how the body actually uses them for this job.

Why are iron and folic acid paired together?

Iron and folate act on different steps of the same process. Iron is the core component of haemoglobin, the protein in red blood cells that carries oxygen; without enough iron, the body makes smaller, paler red cells that carry less oxygen (iron-deficiency anaemia). Folate is needed for DNA synthesis during cell division, including the division that produces new red blood cells; without enough folate, red cells grow abnormally large and don't mature properly (megaloblastic anaemia).

A population can have both gaps at once, and India does: NFHS-5 (2019-21) records anaemia in 57% of women aged 15-49, 52.2% of pregnant women, 59.1% of adolescent girls, and 25% of men aged 15-49. Iron deficiency is the larger single driver of anaemia at a population level, but folate deficiency is common enough (see our folic acid tablets guide for the 37% figure) that pairing the two is more effective public health policy than an iron-only programme.

How much iron and folic acid do you need a day?

Life stage	Iron RDA (ICMR-NIN 2020)	Folate RDA (ICMR-NIN 2020)
Adult man	19 mg/day	300 µg/day
Adult woman	29 mg/day	220 µg/day
Pregnancy	40 mg/day	570 µg/day (DFE)
Lactation	23 mg/day	330 µg/day

Two things are worth noticing in this table. First, the pregnancy iron RDA (40 mg) is the highest figure here, which tracks with the extra blood volume and foetal iron transfer pregnancy requires. Second, the lactation figure (23 mg) is actually lower than the non-pregnant adult woman's baseline (29 mg), which isn't a typo: it reflects ICMR-NIN's 2020 methodology, which accounts for the reduced menstrual iron loss most women experience while breastfeeding, on top of milk production's own iron cost. Third, these are general population RDAs, not a treatment dose: someone with a confirmed iron-deficiency diagnosis is usually prescribed a therapeutic dose well above the RDA, for a defined period, under medical supervision, which is a different number from the table above and not one to self-select.

For the fuller folate-specific picture, including the pregnancy pre-conception window, see our folic acid tablets guide and pregnancy dose guide; this page focuses on the iron side and the combined product.

Who typically needs an iron and folic acid tablet?

• Menstruating women, since regular blood loss is a major driver of the higher female iron RDA and a common reason for iron-deficiency anaemia.
• Pregnant and lactating women, where both iron and folate needs rise and India's national programme specifically targets this group (see the pregnancy dose guide).
• Adolescent girls and boys, covered by India's Weekly Iron-Folic Acid Supplementation (WIFS) programme, since rapid growth increases both nutrient needs.
• Vegetarians, since plant-based (non-haem) iron is less readily absorbed than the iron in meat and fish, and vegetarian diets can also run lower in folate depending on food choices.
• Anyone with a doctor-confirmed iron-deficiency or folate-deficiency diagnosis, based on an actual blood test, not a symptom checklist.

This is general educational context, not an instruction to start supplementing; whether you personally need iron, folic acid, or both, and at what dose, is a conversation with your doctor, ideally backed by a simple blood test.

What forms does the iron come in, and does it matter?

Iron supplements use different iron salts, and the milligram number on the front of the pack is not always the elemental iron your body actually gets. Common forms include ferrous sulfate (roughly 20% elemental iron by weight), ferrous fumarate (roughly 33% elemental iron), and ferrous ascorbate (elemental iron content varies by formulation; often paired with vitamin C to aid absorption). A tablet listing "300 mg ferrous fumarate," for instance, does not mean 300 mg of elemental iron, since only part of that weight is iron itself.

This matters for two reasons: it affects how much iron you're actually getting relative to the RDA table above, and different salts vary in gut tolerability, some people find one form easier on the stomach than another. Neither form is universally "better"; a doctor or pharmacist can help match the form to your tolerance and your prescribed elemental-iron target.

What does India's national IFA programme actually give people?

India's Anemia Mukt Bharat strategy, under the Intensified National Iron Plus Initiative, supplies different IFA tablets to different beneficiary groups rather than one universal dose:

Beneficiary group	Typical IFA dose	Frequency
Pregnant and lactating women	60 mg elemental iron + 500 µg folic acid	Daily, for 180 days (antenatal), plus 180 days postnatal
Adolescents (10-19 years)	60 mg elemental iron + 500 µg folic acid	Weekly (Weekly Iron-Folic Acid Supplementation, WIFS)
Children (6-59 months)	20 mg elemental iron + 100 µg folic acid (syrup)	Biweekly

Source: MoHFW/National Health Mission, Anemia Mukt Bharat / Intensified National Iron Plus Initiative guidelines.

The adolescent tablet is colour-coded blue ("iron ki neeli goli") specifically to distinguish it from the red tablet given to pregnant and lactating women, a deliberate design choice to reduce mix-ups in the field. Doses for confirmed anaemia (rather than routine prevention) are higher and time-bound, and are set by a doctor, not by this table.

Is iron and folic acid supplementation safe? Any side effects?

At standard preventive doses, iron and folic acid supplementation is well tolerated by most people. The most common side effects are gastrointestinal, gastric upset, constipation, nausea, or darker stools, and taking the tablet with food can reduce these for most people (NIH ODS, as of July 2026). NIH ODS sets the tolerable upper intake level for iron at 45 mg/day for adults from supplements and fortified food combined; the government IFA tablet's 60 mg dose exceeds this general adult UL, which is why it is issued through a targeted, time-bound public health programme with medical oversight, not as an untargeted everyday product.

One safety point genuinely differs between the two nutrients: unlike folate, iron carries a real overload risk over time, particularly for men and post-menopausal women, whose iron losses are typically lower, so extra iron without a confirmed deficiency is generally discouraged rather than harmless. A blood test, not a hunch, is what should trigger iron supplementation for anyone outside the specifically targeted groups above.

What should you look for in an iron and folic acid tablet?

• The elemental iron content, not just the salt's total weight, since this is what actually counts towards your dose.
• A dose that matches an actual, doctor-identified need, rather than a number picked because it sounds substantial.
• The iron salt form your stomach tolerates, since gut side effects are the main reason people stop taking iron supplements partway through a course.
• FSSAI-licensed manufacturing and clear labelling, with a real batch number and expiry date.
• Whether you need iron at all, since taking iron you don't need carries more downside than taking folic acid you don't strictly need.

Can food alone cover iron and folate needs?

Diet contributes meaningfully to both nutrients but rarely closes the gap entirely for the groups most affected by anaemia in India. Iron-rich foods include meat, fish, and poultry (haem iron, more readily absorbed) and dals, legumes, and leafy greens (non-haem iron, less readily absorbed, but improved by pairing with vitamin-C-rich foods like citrus or tomatoes). Folate-rich foods overlap with the same leafy greens, dals, and citrus, covered in more depth in our folic acid tablets guide.

Given how widespread anaemia remains at a population level in India (57% of women, per NFHS-5), diet alone is rarely treated as sufficient by public health policy, which is exactly why the fortification and IFA supplementation programmes exist alongside dietary advice, not instead of it.

Where does active folate (5-MTHF) fit if iron isn't your issue?

Not everyone who needs more folate also needs more iron. If a blood test shows your iron status is fine but your folate intake or status is the actual gap, a standalone folate product, whether standard folic acid or active folate (5-MTHF), is the more direct choice than an iron-folic acid combination you don't need the iron half of.

Q6, Express Melts' active-folate oral strip, is one option here: 570 µg of 5-MTHF per strip, dissolving on the tongue with no water needed. It addresses the folate side of this pairing specifically; it is not an iron product and is not a substitute for an iron-folic acid tablet where iron deficiency has actually been diagnosed. Which product, and which nutrient, is the right target for you is a question for your doctor, ideally informed by a blood test rather than symptoms alone.

Who this is for, and when to see a doctor

This piece is for anyone trying to understand why iron and folic acid come bundled together so often in Indian healthcare, rather than guessing at the reason. It is educational information, not a personalised recommendation or a diagnosis. Talk to your doctor before starting, changing, or stopping any iron or folate supplement, especially if you are pregnant, managing a chronic condition, have a family history of iron overload disorders, or have not had a blood test confirming an actual deficiency.

Frequently Asked Questions

What is an iron and folic acid tablet used for?

It's used to support red blood cell production where either or both nutrients fall short, since iron builds haemoglobin and folate supports the cell division behind new red cells. It's the standard combination in India's national anaemia-prevention programmes.

How much iron and folic acid should an adult take per day?

ICMR-NIN sets adult RDAs at 19 mg/day iron for men and 29 mg/day for women, alongside 300 µg and 220 µg folate respectively. Pregnancy and lactation carry different, programme-specific doses; your own requirement should be confirmed by a doctor or blood test.

Can I take an iron and folic acid tablet without a doctor's advice?

For folic acid alone, most healthy adults can, at standard doses. For iron specifically, it's better to confirm an actual deficiency first, since iron carries a real overload risk that folate doesn't, particularly for men.

What color is the government iron and folic acid tablet in India?

India's national programme uses colour-coding to reduce mix-ups: a blue tablet (60 mg iron plus 500 µg folic acid, weekly) for adolescents, and a red tablet (the same dose, daily) for pregnant and lactating women.

Why does India pair iron with folic acid instead of giving them separately?

Because anaemia in India is rarely caused by just one nutrient gap; NFHS-5 data shows widespread deficiency risk across the population, and both nutrients feed into red blood cell production through different pathways, so treating both together is more effective public health policy.

Does Q6 contain iron?

No. Q6 is an active-folate (5-MTHF) strip, not an iron product. It addresses the folate side of this pairing only; anyone with a confirmed iron deficiency needs an iron-containing product or a combination tablet, not Q6 alone.
