Estimated Energy Requirement (EER)

estimate of the energy (kcal) intake needed to match the energy use of an average person in a specific life stage

Tolerable Upper Intake Level (UL)

maximum chronic daily intake level of a nutrient that is unlikely to cause adverse health effects in almost all people in a specific life stage
