Food Fortification Initiative (FFI) is an organization that focuses on reducing micronutrient deficiencies by helping country leaders plan, implement and monitor fortification programs.
A review by GiveWell concluded that effective micronutrient fortification programs could be as cost-effective as their top-rated programs. Due to difficulties in assessing FFI's causal role in implementing their programs, however, GiveWell has not attempted an explicit cost-effectiveness analysis of this organization's impact. Because of these uncertainties, GiveWell currently rates FFI a standout charity—an organization with exceptional potential for impact which does not fully meet all of their criteria to be rated a top charity. As GiveWell believes that further research is unlikely to resolve these uncertainties, it does not plan to conduct additional investigations on FFI for the time being (GiveWell 2016).
