Sample size: up to 550 at midline, up to 800 at endline. Testing constraints maximise the number of tests per day to 5/ day. We will test the maximum number of children available per the number of slots available per day.

-Is aged 8 months (+/-14 days) at the time of randomisation
-Is not expected to leave the study site (leave local village or the Rupganj area) for more than 1 week over the next 3 months, or for more than one month over the next 12 months.
-Has a legally acceptable representative capable of understanding the informed consent document and providing consent on the participant’s behalf.
Minimum age
8 Months
Maximum age
8 Months
Sex
Both males and females
Can healthy volunteers participate?
Yes
Key exclusion criteria
Children meeting any of the following criteria will be excluded from the study:
- Has a capillary Hb at screening of <8.0g/dL at the time of screening
- Drinking water iron level >1gm/L
- Has an established diagnosis of any homozygous or compound heterozygous haemoglobinopathies (i.e. beta thalassaemia major, HbE-beta thalassaemia).
- Current infective illness with fever (respiratory infection, diarrhoea); however, children will be screened again after recovery and recruited as long as the meet the age eligibility criteria at second screening.
- Legal guardian unwilling or unable to provide written informed consent.
- Has not received iron supplements or iron-containing multiple micronutrient powders in the previous month. Families who self-procure iron/MMP during or after the intervention period will not be dropped from the study, but we will record the dose and duration and continue monitoring
- Known congental anomaly, developmental disorder or severe developmental delay
- It is not possible to test the child due to physical or behavioural problems
- Children of multiple birth e.g. twin, triplets

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Blinding will be achieved through the use of identical packaging which will carry the code. Allocation concealment will be achieved through use of central randomisation and use of number pouches containing study medications.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A statistician not involved in the study will generate a random sequence using a computer program to undertake randomisation and will hold the codes until the study ends. The study will use individual block randomization, with stratification by sex and sub-centre to maintain balance between intervention arms.
Masking / blinding

Who is / are masked / blinded?

Efficacy
Statistical methods / analysis
The primary analysis will be by intention-to-treat and in accordance with International Conference on Harmonization E9 statistical principles. A detailed statistical analysis plan with details of the proposed analyses will be finalised before the trial database is locked for final analysis. Analyses will be undertaken on an intention-to-treat basis. Descriptive statistics will be presented for all outcomes, by treatment groups across the follow-up time points. Outcomes will be assessed using regression models, with placebo as the reference, and incorporating key confounders and unbalanced baseline factors into the model.
