Daily Requirement of Vitamin A (Retinol)
The Recommended Dietary Allowance (RDA) is a measure of how much of a nutrient different people should get every day. For Vitamin A (Retinol), the RDA is:
- 400 micrograms a day for infants 0-6 months old.
- 500 micrograms a day for infants 7-12 months old.

Also, the RDA is higher for women when pregnant or breastfeeding. The RDA for vitamin A is increased to 770 micrograms a day during pregnancy, and 1300 micrograms a day while breastfeeding.
Vitamin A deficiencies are rare in developed countries, but are regularly seen in some poorer regions. The daily requirement of vitamin A is generally easy to get with a balanced and varied diet that includes adequate amounts of fruits and vegetables.
The RDA values are established by the National Academy of Sciences.
