Eleanor Crook Foundation outlines where it is concentrating its philanthropic contributions for scaling up multiple micronutrients supplementation (MMS). The Eleanor Crook Foundation intends to strategically invest in three main areas to support MMS scaling: (1) implementation to enhance MMS delivery at scale in key East African countries; (2) research on demand creation for MMS using creative solutions; and (3) country-level advocacy for inclusion of MMS delivery as the antenatal standard of care in national guidelines.
