What The Numbers Mean
Many of the terms you see on labels or supplement web sites can help you understand how much of the vitamin or mineral you should take. For example, here are some guidelines set up by the Institute of Medicine: The RDA (Recommended Dietary Allowance) and the AI (Adequate Intake) are the amounts of a vitamin or mineral you need to keep healthy and stay well-nourished. For certain nutrients, the higher you go above the UL, the greater the chance you’ll have problems.
Separate from the RDA and the UL, the Food and Drug Administration uses a different measure for the nutrients you need: The DV (Daily Value) is the only measurement you’ll find on food and supplement labels. That number is the amount of a vitamin or nutrient that you should get for top health from a diet of 2,000 calories a day. The DV is sometimes the same as the RDA.

(Note: The FDA initially gave large manufacturers and small manufacturers until July of 2018 and 2019, respectively, to update their labels with the new DVs. However, in September 2017, it extended these deadlines to January 1 of 2020 and 2021, respectively.

Return to table 3 footnote 14 referrer Table 3 footnote 15 Although AIs have been set for choline, there are few data to assess whether a dietary supply of choline is needed at all stages of the life cycle, and it may be that the choline requirement can be met by endogenous synthesis at some of these stages.
Return to table 3 footnote 15 referrer Table 3 footnote b In view of evidence linking the use of supplements containing folic acid before conception and during early pregnancy with reduced risk of neural tube defects in the fetus, it is recommended that all women capable of becoming pregnant take a supplement containing 400μg of folic acid every day, in addition to the amount of folate found in a healthy diet.
