This article outlines the development and use of the Sight and Life Multiple Micronutrient Supplements (MMS) Supply toolkit. After using the toolkit, it is expected that countries will be able to: determine whether MMS would need to be imported or
produced in the country for use in public health programs; document in-country capacity to procure ingredients and produce an MMS product that can be delivered to the end consumer or institutional buyer (e.g., Ministry of Health); provide guidance on actions needed to ensure competitive and affordable sources of an MMS supply; and assess the impact of shifting from import to local production of MMS and vice versa on countries or regions.
