Many people get enough vitamins through eating a healthful and varied diet. However, women have slightly different nutritional needs to men, and these needs can change during the various stages of a woman’s life.
In this article, we look at what vitamins and other nutrients a woman needs at different stages in her life.
Recommended dietary allowances (RDA)
In the United States, the Food and Nutrition Board (FNB) provide guidance on nutrition and set the RDAs and adequate intakes (AIs) for vitamins.
The FNB set the RDA for a specific vitamin when there is enough scientific evidence to establish a daily dietary intake.
This happens when the vitamin is shown to meet the nutritional requirement of 97 to 98 percent of healthy people within a particular group.
If the FNB do not have sufficient scientific evidence to establish an RDA, they usually recommend an AI instead.
