Vitamin A: Natural sources vs 'Golden' rice

Publication - 1 February, 2001
How much vitamin A do people need to prevent deficiency?

The FAO/WHO recommend a daily intake of 500 to 850 micrograms of vitamin A for adults (500 micrograms for females, 600 micrograms for males, 800 micrograms during pregnancy, and 850 micrograms during breast feeding), and a daily intake of 400 micrograms for a child between 1 to 3 years of age 1. This level of intake is set to prevent clinical signs of deficiency and to allow normal growth. Higher levels of vitamin A are needed during breast feeding, as the milk is the source of vitamin A for the baby.
