Maximum Fortification Level (MFL)

  • Assessment
  • Planning
  • Diet
  • Fortification
  • Supplementation


The level represents the upper limit of the micronutrient content to be achieved by the fortification process. MFL is given by increasing the TFL (Target fortification level) by an amount equivalent to two coefficients of variation of the measured micronutrient content of a fortified food at the factory.
