It was introduced in 1997 in order to broaden the existing guidelines known as Recommended Dietary Allowances (RDAs, see below). The DRI values differ from those used in nutrition labeling on food and dietary supplement products in the U.S. and Canada, which uses Reference Daily Intakes (RDIs) and Daily Values (%DV) which were based on outdated ...
For vitamin B12, the U.S. Recommended Dietary Allowance (RDA) for pregnancy is 2.6 μg/day, for lactation 2.8 μg/day. Determination of these values was based on a RDA of 2.4 μg/day for non-pregnant women plus what will be transferred to the fetus during pregnancy and what will be delivered in breast milk.

In recent times, [when?] Dietary Reference Values are under the interest of the European Food Safety Authority too, which intend to extend them at the EU level. EFSA is the equivalent of the Food and Drug Administration (FDA) in the USA, and acts as watchdog inside the European market in order to establish a common ground on food safety requirements and nutrition as well.
RDA for pregnancy equals 2.6 μg/day. RDA for lactation equals 2.8 μg/d. For infants up to 12 months, the adequate intake (AI) is 0.4–0.5 μg/day. (AIs are established when there is insufficient information to determine EARs and RDAs.) For children ages 1–13 years, the RDA increases with age from 0.9 to 1.8 μg/day.
For women, the values are 199, 153 and 459 μg/day, respectively. This means that fortification led to a bigger increase in folic acid intake than first projected, and that more than half the adults are consuming more than the RDA of 400 μg (as DFEs). Even so, fewer than half of pregnant women are exceeding the pregnancy RDA of 600 μg/day. [141]
The RDA during pregnancy is 1.4 mg/day and the RDA for lactating females is 1.6 mg/day. For infants up to the age of 12 months, the Adequate Intake (AI) is 0.3–0.4 mg/day and for children aged 1–13 years the RDA increases with age from 0.5 to 0.9 mg/day.
World Health Organization "Recommendations for preformed vitamin A supplements for mothers during pregnancy" states that "health benefits are expected for the mother and her developing fetus with little risk of detriment to either, from a daily supplement not exceeding 10,000 IU vitamin A (3000mcg RE) at any time during pregnancy."
