DRI values change per a person’s age and biological sex, and include:
- Recommended Dietary Allowance (RDA): This is the average daily intake level, sufficient to meet the nutritional requirements of almost every healthy person.
- Adequate Intake (AI): This intake level ensures adequate nutrition and is set when there is insufficient proof to develop an RDA.
- Estimated Average Requirement (EAR): This is the average daily intake level that is estimated to satisfy the needs of 50% of healthy people.
- Tolerable Upper Intake Level (UL): This is the highest intake level a person can consume which would unlikely have a negative health effect.
RDAs for vitamin A are typically shown as Retinol Activity Equivalents.
This is because the body converts the different compounds in vitamin A into retinol.
Due to this:
1 microgram (mcg) RAE is equivalent to:
- 1 mcg retinol
- 2 mcg supplemental beta-carotene
- 12 mcg dietary beta-carotene
- or 24 mcg dietary alpha-carotene or beta-cryptoxanthin
The following table shows the
|0–6 months||400 mcg RAE||600 mcg|
|7–12 months||500 mcg RAE||600 mcg|
|1–3 years||300 mcg RAE||600 mcg|
|4–8 years||400 mcg RAE||900 mcg|
|9–13 years||600 mcg RAE||1,700 mcg|
|14–18 years||900 mcg RAE (male) 700 mcg RAE (female)||2,800 mcg|
|19–50 years||900 mcg RAE (male) 700 mcg RAE (female)||3,000 mcg|
|51+ years||900 mcg RAE (male) 700 mcg RAE (female)||3,000 mcg|
For those who are pregnant or breastfeeding, the following RDAs apply:
|Age||RDA in pregnancy||RDA if breastfeeding||UL in pregnancy||UL if breastfeeding|
|14–18 years||750 mcg RAE||1,200 mcg RAE||2,800 mcg||2,800 mcg|
