In 1993 there was proposed a new system of monographs for vitamins, replacing the RDA (Recommended Daily Allowance). This system is called the Dietary Reference Intakes.
The DRI includes four subcategories, as follows:
Recommended Dietary Allowance/RDA - Daily average intake of a vitamin to meet the needs of most of a given life stage/gender group in good health (97-98%). This is a goal for intake, not assessing a diet.
AI/Adequate Intake Level - Used when EAR cannot be scientifically determined, this is based on observations of the nutrient intake of relatively healthy people; assumed to be adequate.
Tolerable Upper Intake Level/UI - Estimated maximum level at which a nutrient is thought to be safe. Increased risk goes up as ingestion goes above this level.
Estimated Adequate Intake (EAR) - This is the average daily nutrient intake level estimates to meet the requirement of 50% of the individuals in a particular life stage/ gender group. It is population weighed and is considered to be the most accurate reflection of food-nutrient needs of a group, excluding young children and pregnant/lactating women, whose needs differ greatly.
It is important to note before closing that the RDA & AI may not be adequate for people recovering from deficiencies, or for those in a diseased or compromised state. They are used, rather, as a tool for planning and assessing a population's healthy diet.
