2. Justification Home fortification with MNP has proved to be efficacious and effective in reducing the prevalence of iron deficiency anaemia in young children. Today, MNP are successfully used in 45-50 countries worldwide. Based on the large body of evidence available, the WHO strongly recommends the use of MNP containing at least iron, vitamin A and zinc to improve iron status and reduce anaemia in children 6-23 months of age where the prevalence of anaemia in children under two years or under five years of age is 20% or higher.
