Intake Recommendations. Most women need 2,333 International Units, or 700 micrograms, of vitamin A each day, while men need 3,000 IU or 900 micrograms, according to the Linus Pauling Institute. Because vitamin A plays such an important role in a developing babyâs development, pregnant and breastfeeding mothers need more vitamin A -- 2,567 IU and 4,333 IU, respectively.
66% of all vitamin A intake in the American diet comes from retinol or preformed vitamin A added to foods (mostly as retinyl palmitate). Vitamin A is also found in supplements (as retinyl palmitate and retinyl acetate). Tolerable upper limit: 10,000 IU daily (see more below).
