DRI Tables and Application Reports


The Dietary Reference Intakes (DRIs) are developed and published by the Institute of Medicine (IOM). The DRIs represent the most current scientific knowledge on nutrient needs of healthy populations. Please note that individual requirements may be higher or lower than the DRIs.
