This review of micronutrient policy processes in South Africa serves as a companion piece to two parallel studies in Malawi and Zambia. All three studies employ the Kaleidoscope Model of policy change to trace the causal forces leading to key micronutrient policy decisions in each of the three countries. After outlining the overall micronutrient policy process in South Africa, the study focuses on policy decisions regarding vitamin A supplementation, fortification with iodine, iron and multinutrient fortificant, and the reduction of sodium in foods.
