Methods	Design: randomised controlled trial comparing multiple micronutrient powder containing 15 micronutrients vs a micronutrient supplement containing 3 micronutrients Unit of randomisation: individual randomisation
Participants	Setting: Palestine Sample size: target sample size of 200; unclear how many enrolled Age range: 5 months + 2 weeks Inclusion criteria Aged 5 months + 2 weeks Normal z scores (> −2 to < 2 standard deviations) of weight‐for‐age, length‐for‐age, and head circumference‐for‐age Birthweight of 2.5 to 4 kg Appropriate for gestational age (between 10th and 90th percentiles) Blood level of haemoglobin of 11 g/dL Breastfed for at least 4 months United Nations Relief and Works Agency (UNRWA) clinics for vaccination and/or routine child's growth follow‐up Exclusion criteria Preterm infants (< 37 weeks) History of chronic disease Infants of diabetic mothers History of complications during delivery (aspiration, trauma) History of congenital or acquired neurological diagnosis
Interventions	Individuals randomised to 2 groups: Intervention (100 participants): micronutrient powder with national micronutrient supplement containing 15 vitamins and minerals (unclear dose), produced by DSM (MixMe) Control (100 participants): national micronutrient supplement containing vitamin A, vitamin D, and iron (unclear dose) Administration: both groups given 3 sachets/week for 12 months
Outcomes	Primary Anthropometric measurements Haemoglobin concentration (capillary assessment using colorimeter) Secondary Calorie intake, assessed via 24‐hour recall Nutrient intake, assessed via 24‐hour recall Timing of outcome assessment: anthropometrics assessed at baseline and throughout the study period (every 3 to 6 months); haemoglobin concentration assessed secondary outcomes assessed at baseline, 6 months of intervention, and end of the intervention period; secondary outcomes assessed at baseline, end‐line, and 3 months after the end of the intervention
