Function
Dations for vitamin A, as well as other nutrients, are provided in the Dietary Reference Intakes (DRIs) developed by the Food and Nutrition Board at the National Academies of Sciences, Engineering, and Medicine. Dri is a term for a set of reference intakes that are used to plan and assess the nutrient intakes of healthy people.
An RDA is an intake level based on scientific research evidence. Adequate Intake (AI): This level is established when there is not enough scientific research evidence to develop an RDA. Dietary reference intakes for vitamin A:
Infants (AI)
0 to 6 months: 400 micrograms per day (mcg/day)
7 to 12 months: 500 mcg/day
The Recommended Dietary Allowance (RDA) for vitamins is how much of each vitamin most people should get each day.
