Weekly Iron and Folic Acid Supplementation
On this page
Direct answer
Monday is iron day in India's adolescent health calendar: the Weekly Iron and Folic Acid Supplementation (WIFS) programme gives every adolescent aged 10-19 years — school-going and out-of-school — one supervised IFA tablet (100 mg elemental iron with 500 micrograms of folic acid) every week through the year, complemented by biannual albendazole deworming, screening of the anaemic, and nutrition education. Launched nationally in 2012-13 and carried later under the Rashtriya Kishor Swasthya Karyakram and Anaemia Mukt Bharat umbrella, it attacks an anaemia prevalence that NFHS-5 put at roughly 57 per cent among women aged 15-49 and about 59 per cent among adolescent girls — a burden that silently carries into maternal anaemia and adverse birth outcomes a decade later. The weekly (not daily) schedule is the conceptual heart: iron given once a week synchronises with intestinal mucosal turnover, improving absorption and tolerability while maintaining a steady supply to the marrow.
What you must remember
- The regimen: one IFA tablet weekly — 100 mg elemental iron plus 500 micrograms folic acid — for 52 weeks a year, supervised consumption (the "fixed day" strategy), for ages 10-19.
- Deworming attached: albendazole 400 mg twice a year, ideally six months apart, since soil-transmitted helminths feed the same iron-deficiency cycle.
- Coverage groups: school-going adolescents through teachers (classes VI-XII) and out-of-school adolescents through anganwadi centres and ASHAs — the exam expects both channels.
- Screening and referral: adolescents with pallor or suspected severe anaemia are tested and referred; the programme is supplementation with a detection layer, not treatment.
- The weekly-dose logic: gastrointestinal mucosal cells renew every few days, so weekly dosing rides the "mucosal block" physiology — better absorption, fewer side-effects, better compliance than daily iron.
- Prevalence anchors: NFHS-5 (2019-21) — anaemia among women 15-49 about 57 per cent, adolescent girls 15-19 around 59 per cent, children 6-59 months about 67 per cent.
- Programme home: launched 2012-13; now nested in RKSK (2014) and Anaemia Mukt Bharat (2018), which extended iron supplementation across six beneficiary age groups.
A school's Monday, and why weekly works
Picture a government high school's assembly-line Monday: class teachers under the principal's oversight hand each adolescent a tablet, watch swallowing, record the register, and repeat the nutrition message; twice a year the same machinery delivers albendazole. Out-of-school adolescents meet the same schedule at the anganwadi. The supervision is the intervention — unsupervised weekly iron historically meant tablets in pockets and side-effect rumours in the village.
The physiological justification is viva gold. Daily iron saturates duodenal enterocytes, which then block further absorption (the mucosal block concept) and produce the nausea and constipation that wreck compliance; a weekly dose arrives as the mucosal lining has turned over, meeting fresh, hungry enterocytes — so absorption fraction rises, gastrointestinal intolerance falls, and haemoglobin response remains adequate for prevention. Add the programme's second insight: adolescents are the catchment precisely because girls enter marriage and pregnancy soon after, and pre-pregnancy iron stores are cheaper to build than maternal anaemia is to treat. WIFS is thus a lifecourse intervention disguised as a tablet distribution scheme — a framing that separates policy understanding from list-recitation.
Where students slip
The numbers get shuffled: 100 mg elemental iron with 500 micrograms folic acid weekly for adolescents, versus 100 mg daily for 100 days (twice, after the first trimester) in pregnancy, versus iron syrup or dispersible tablets for young children under Anaemia Mukt Bharat — three regimens, three audiences, one exam. Second, the target: WIFS covers 10-19 years regardless of school status, and forgetting the out-of-school anganwadi channel is the classic omission. Third, candidates blur WIFS with Anaemia Mukt Bharat: AMB (2018) is the umbrella strategy across six age groups with six interventions and institutional mechanisms, while WIFS is the adolescent-specific supplementation programme absorbed within it. A favourite viva probe is the weekly-versus-daily rationale — mucosal turnover and the block to absorption — and an answer that explains the physiology rather than asserting "weekly is easier" earns the top band.
Frequently asked questions
What dose does WIFS provide and to whom?
One supervised tablet of 100 mg elemental iron plus 500 micrograms folic acid weekly, for 52 weeks a year, to all adolescents aged 10-19 — school-going and out-of-school.
Why weekly rather than daily iron?
Intestinal mucosal cells turn over every few days, so weekly dosing meets fresh enterocytes, improves fractional absorption, reduces gastrointestinal side-effects and sustains compliance.
What deworming accompanies WIFS?
Albendazole 400 mg twice yearly, about six months apart, delivered through the same school and anganwadi platforms to break the hookworm-driven iron loss.
How prevalent is anaemia among Indian adolescents?
NFHS-5 found roughly 59 per cent of adolescent girls aged 15-19 anaemic and about 57 per cent of women aged 15-49 — the burden WIFS exists to reduce before childbearing.
How does WIFS relate to Anaemia Mukt Bharat?
WIFS (2012-13) is the adolescent supplementation programme; Anaemia Mukt Bharat (2018) is the broader strategy across six age groups that subsumes and strengthens it with testing, treatment and food fortification interventions.
