Recommended Dietary Allowance
Recommended Dietary Allowance (RDA): Average daily level of intake sufficient to meet the nutrient requirements of nearly all (97%–98%) healthy individuals; often used to plan nutritionally adequate diets for individuals.
μg-rae/day: milligram retinol activity equivalent per day
Adequate Intake
Adequate Intake (AI): Intake at this level is assumed to ensure nutritional adequacy; established when evidence is insufficient to develop an RDA.
μg-rae/day: milligram retinol activity equivalent per day
Estimated Average Requirement
Estimated Average Requirement (EAR): Average daily level of intake estimated to meet the requirements of 50% of healthy individuals; usually used to assess the nutrient intakes of groups of people and to plan nutritionally adequate diets for them; can also be used to assess the nutrient intakes of individuals.
μg-rae/day: milligram retinol activity equivalent per day
Tolerable Upper Intake Level
Tolerable Upper Intake Level (UL): Maximum daily intake unlikely to cause adverse health effects.
μg-rae/day: milligram retinol activity equivalent per day
