Personal information
Iron needs vary by age, sex, and pregnancy status
Diet & iron intake
Chai with meals is a major Indian risk factor for low iron
Women's health factors
Medical & absorption factors
Surgery, childbirth, blood donation, or GI bleeding in the past 6 months counts as recent blood loss
Symptoms (select all that apply)
These symptoms can overlap with thyroid, B12, and vitamin D deficiencies—lab testing confirms iron status.
How this Iron Deficiency / Anemia Risk Calculator works
Enter your age, sex, diet type (vegetarian, non-vegetarian, or vegan), red meat consumption, tea or coffee habits with meals, vitamin C pairing with iron foods, women's health factors (heavy periods, pregnancy, breastfeeding), medical factors (recent blood loss, GI conditions, antacid use), and any symptoms (fatigue, pale skin, shortness of breath, dizziness, brittle nails, restless legs, ice craving, hair loss).
We apply an ICMR-aligned weighted scoring system for the Indian population—higher risk points for reproductive-age women, heavy menstruation, pregnancy, vegetarian/vegan diet, tea with meals, low vitamin C, GI conditions, and classic anemia symptoms. Results include risk level (Low, Moderate, High, Very High), top risk factors, estimated daily iron need in mg, Indian food sources, and iron absorption tips. If your result is High or Very High, we prompt you to book a CBC and serum ferritin test—only lab values confirm deficiency; this tool screens lifestyle and symptom risk.

NFHS-5 data show over 57% of Indian women aged 15–49 are anemic—iron deficiency is the leading cause. Vegetarian diets, chai with meals, heavy menstruation, pregnancy, and GI blood loss drive widespread deficiency. Our free Iron Deficiency / Anemia Risk Calculator uses an ICMR-aligned weighted scoring system to estimate your risk level, identify top risk factors, calculate estimated daily iron need in mg, recommend Indian food sources, provide absorption tips, and prompt blood testing when risk is High or Very High.
Pair results with our Micronutrient Deficiency Risk Calculator, Vitamin D Deficiency Calculator, and Period & Menstrual Cycle Calculator for a complete picture of nutrition and women's health.
Why Assess Iron Deficiency / Anemia Risk?
Iron is essential for hemoglobin production, oxygen transport, energy metabolism, immunity, and cognitive function. Your body cannot make iron—it must come from food or supplements. When stores deplete, iron deficiency develops first (low ferritin), then iron deficiency anemia (low hemoglobin). In India, vegetarian diets, tea with meals, menstrual blood loss, and pregnancy sharply increase risk.
The Indian Council of Medical Research (ICMR) recommends 17 mg/day iron for adult men, 21 mg/day for premenopausal women, and 35 mg/day during pregnancy. Deficiency is often silent until fatigue, pallor, or breathlessness appear. A CBC and serum ferritin blood test (₹300–800 at most Indian labs) is the gold standard—but this calculator helps you understand whether testing is urgent based on lifestyle risk factors.
1What You Enter
Personal & diet inputs
- Age — reproductive age, pregnancy, and elderly have higher needs
- Sex — women have 2–3× higher anemia rates in India
- Diet type — Vegetarian / Non-Vegetarian / Vegan
- Red meat consumption — Never / Sometimes / Regularly
- Tea or coffee with meals — tannins block iron absorption
- Vitamin C with iron meals — enhances non-heme iron uptake
Health factors & symptoms
- Heavy menstrual bleeding — leading cause in Indian women
- Pregnancy / breastfeeding — sharply increases iron demand
- Recent blood loss — surgery, donation, GI bleeding
- GI conditions — celiac, IBD, ulcers
- Antacid / PPI use — reduces iron absorption
- Symptoms checklist — Fatigue, pallor, breathlessness, pica, restless legs, and more
Example (Very High risk — woman, 32, Mumbai)
Age 32, female, vegetarian, no red meat, heavy periods, chai always with meals, rare vitamin C, fatigue + pale skin + ice craving → Very High risk, ~21 mg/day estimated need, get-tested prompt.
Example (Low risk — man, 40, non-veg)
Age 40, male, non-vegetarian, regular red meat, rarely drinks tea with meals, no symptoms → Low risk, ~17 mg/day estimated need.
2Scoring Logic — ICMR-Aligned Weighted Risk Factors
High-weight risk factors
The score increases most for: currently pregnant (+20 pts), heavy menstrual bleeding (+18 pts), recent significant blood loss (+16 pts), vegan diet (+14 pts), GI conditions (+14 pts), female sex (+10 pts), and daily tea/coffee with meals (+10 pts). Moderate weights apply to vegetarian diet, no red meat, breastfeeding, daily PPI use, rare vitamin C pairing, and classic anemia symptoms.
Risk level thresholds
- Low — 0–18 points
- Moderate — 19–38 points
- High — 39–58 points
- Very High — 59+ points
Estimated daily iron need (mg)
Adult men & postmenopausal women: 17 mg/day · Premenopausal women (15–49): 21 mg/day · Pregnancy: 35 mg/day · Breastfeeding: 21 mg/day. ICMR RDAs assume adequate absorption— vegetarians with tea at meals may need more dietary iron or supplementation under medical guidance.

Blood Test Reference — Hemoglobin & Ferritin
| Test | Normal range | Deficient / anemic |
|---|---|---|
| Hemoglobin (men) | 13–17 g/dL | <13 g/dL |
| Hemoglobin (women) | 12–15 g/dL | <12 g/dL |
| Hemoglobin (pregnancy) | ≥11 g/dL | <11 g/dL |
| Serum ferritin | 30–300 ng/mL (varies by lab) | <15–30 ng/mL |
| MCV (red cell size) | 80–100 fL | <80 fL (microcytic) |
Low ferritin with normal hemoglobin = iron deficiency without anemia. Both low ferritin and low hemoglobin = iron deficiency anemia. This calculator screens risk—it does not replace these lab tests.
Symptoms of Iron Deficiency — What to Watch For
Early / mild signs
- Fatigue and reduced stamina
- Pale skin, lips, or inner lower eyelids
- Mild shortness of breath on stairs
- Headache and poor concentration
- Cold hands and feet
Moderate / severe signs
- Restless legs syndrome (especially at night)
- Craving ice, clay, or starch (pica)
- Brittle or spoon-shaped nails (koilonychia)
- Hair thinning or increased shedding
- Rapid heartbeat, chest pain, or fainting (urgent)
Many symptoms overlap with thyroid disorders, vitamin D deficiency, and B12 deficiency—blood tests help distinguish causes.
Understanding Iron Deficiency vs. Anemia
Iron deficiency means depleted body iron stores (low ferritin) before hemoglobin drops. Iron deficiency anemia means low hemoglobin with small, pale red blood cells. You can be iron deficient without anemia—especially early on. Both conditions benefit from dietary changes and, when confirmed by labs, iron supplementation under medical guidance.
Other anemia types exist—B12/folate deficiency, chronic disease, thalassemia trait, and hemolysis. This calculator screens iron deficiency risk specifically; your doctor may order additional tests (B12, folate, reticulocyte count) if iron studies are normal but anemia persists.
Indian Food Sources of Iron
Non-Vegetarian
- Chicken/mutton liver — highest heme iron
- Red meat — mutton, beef (2–3×/week)
- Fish — bangda, surmai, sardines, prawns
- Egg yolks — 1–2 daily when tolerated
- Chicken and turkey — moderate heme iron
Vegetarian
- Green leafy vegetables — palak, methi, drumstick leaves
- Legumes — masoor dal, chana, rajma, sprouts
- Paneer, tofu, sesame (til), jaggery, dates
- Fortified atta and breakfast cereals
- Amla + lemon with every dal meal
Vegan
- Legumes and lentils — masoor, chana, sprouted moong
- Fortified plant milks and tofu
- Pumpkin seeds, flaxseed, dark leafy greens
- Fortified cereals and whole grains
- Iron supplements often needed (clinician-guided)
Maximizing Iron Absorption — Indian Diet Tips
Heme iron (from meat, fish, eggs) is absorbed 15–35%. Non-heme iron (from plants) is absorbed only 2–10%—but you can triple uptake with the right habits. The classic Indian lunch of dal + sabzi + roti becomes far more iron-efficient with a squeeze of lemon or amla and no chai for one hour after.
| Do this | Effect | Indian example |
|---|---|---|
| Add vitamin C at meals | +2–3× absorption | Lemon on dal, amla chutney, orange after lunch |
| Avoid tea/coffee 1 hr around meals | +50% absorption | Shift chai to 11 AM or 4 PM—not with lunch |
| Soak & sprout legumes | Reduces phytates | Overnight soaked chana, sprouted moong |
| Cook in cast-iron kadai | Small iron boost | Traditional iron tawa for rotis and sabzi |
| Separate calcium from iron | Less blocking | Don't take milk + iron tablet together |
Iron Deficiency & Anemia in India — Key Statistics
- Women: NFHS-5 reports 57% of women aged 15–49 are anemic nationwide
- Children: ~67% of children 6–59 months are anemic—iron deficiency is a leading cause
- Diet: ~30% of Indians are vegetarian; plant iron has much lower bioavailability
- Tea culture: Daily chai with meals is a major modifiable absorption blocker
- Pregnancy: Iron demand rises 2× in pregnancy—deficiency risks low birth weight and preterm birth
- Hidden loss: Menorrhagia and GI bleeding are often underdiagnosed until hemoglobin drops severely
Risk Scoring Points Reference
| Factor | Points | Why it matters |
|---|---|---|

| Ice craving (pica) | +8 | Hallmark sign of iron deficiency |
| Daily PPI/antacid | +10 | Acid suppression blocks iron conversion |
Deficiency Risk Tiers (Educational)
| Level | Score | Action |
|---|---|---|
| Low | 0–18 | Maintain iron-rich diet; test if symptomatic |
| Moderate | 19–38 | Improve diet & absorption habits; consider testing |
| High | 39–58 | Get CBC + ferritin; discuss supplements with doctor |
| Very High | 59+ | Urgent testing; medical evaluation before supplementation |
Worked Example — Step-by-Step
A 32-year-old vegetarian woman in Mumbai: no red meat, heavy periods, chai always with meals, rare vitamin C, reports fatigue, pale skin, and ice craving:
- Age 32, female: +8 pts (reproductive age) + 10 pts (female) = +18 pts
- Vegetarian + no red meat: +8 + 10 = +18 pts
- Heavy menstrual bleeding: +18 pts
- Tea always with meals: +10 pts
- Rare vitamin C: +8 pts
- Fatigue + pale skin + ice craving: +4 + 6 + 8 = +18 pts
- Total score: ~82 points → Very High risk
- Estimated need: ~21 mg/day; get-tested prompt shown for CBC + ferritin
How to Prepare for Iron Blood Tests
- Request CBC (complete blood count) and serum ferritin together
- Fasting is usually not required for ferritin—confirm with your lab
- Avoid iron supplements 24–48 hours before retesting if checking treatment response
- Morning appointments are fine—no special timing needed
- Bring previous reports for trend comparison if available
- Cost: approximately ₹300–800 at Thyrocare, Dr Lal PathLabs, SRL, Metropolis
- Results typically available in 24–48 hours
- Your doctor may also order serum iron, TIBC, or transferrin saturation
Iron Supplements in India — What to Know
| Type | Common brands | Notes |
|---|---|---|
| Ferrous sulfate | Fefol, Orofer, Autrin | Most common; may cause constipation |
| Ferrous fumarate | Fersoft, various generics | Often better tolerated than sulfate |
| Ferrous ascorbate | Ferium, Orofer XT | Combined with vitamin C for absorption |
| Iron + folic acid | Fefol, Livogen | Standard in pregnancy; ANC protocol |
| IV iron | Hospital/clinic only | For severe deficiency or oral intolerance |
Never start high-dose iron without confirmed deficiency and doctor's guidance. Take on empty stomach or with vitamin C if tolerated. Space 2 hours from tea, milk, calcium, and thyroid medication. Black stools are normal on iron supplements.
ICMR Daily Iron Requirements by Group
| Group | RDA (mg/day) | Key note |
|---|---|---|
| Adult men (19+) | 17 | Lower baseline loss |
| Women 19–49 | 21 | Accounts for menstrual losses |
| Pregnancy | 35 | ANC iron-folic acid supplementation standard |
| Breastfeeding | 21 | Continue until lactation ends or as advised |
| Children 1–9 years | 8–12 | Rapid growth increases demand |
When to Get Tested & See a Doctor
Book a blood test if
- Calculator result is High or Very High
- Multiple anemia symptoms present
- Heavy menstrual bleeding or recent blood loss
- Pregnant or planning pregnancy
- Persistent fatigue despite adequate sleep
Seek urgent care if
- Severe weakness, chest pain, or fainting
- Rapid heartbeat or breathlessness at rest
- Black or bloody stools
- Soaking through pads hourly during periods
Who Is at Highest Risk in India?
Lifestyle risk
- Reproductive-age women with heavy periods
- Strict vegetarians and vegans without fortified foods
- Chai/tea drinkers with every meal
- Pregnant and breastfeeding women
Medical risk
- Celiac disease, IBD, or chronic ulcers
- Long-term PPI or antacid use

Common Mistakes When Managing Iron Status
- Taking calcium or antacids with iron supplements — they block absorption
- Drinking chai immediately after dal-based lunch — tannins reduce uptake by half
- Self-prescribing high-dose iron without blood tests — excess iron is harmful
- Ignoring heavy periods as "normal" — menorrhagia is a treatable cause of anemia
- Not retesting ferritin after 8–12 weeks of supplementation to confirm correction
