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.
A good vitamin D intake is 400 IU per day or even 800 IU per day. Although up to 2,000 IU per day is regarded as safe, in most cases you don't need to take that much. Most people get ample vitamin D via the Sun.
