- 11,462 participants
Participants completed an interview, health examination, and a 24hr dietary recall
- In 2003–2006, 53% of the US population used dietary supplements; 34.5% used dietary supplements that contained folic acid.
- Total folate intake (in dietary folate equivalents) was higher for men than for women and higher for non- Hispanic whites than for Mexican Americans and non-Hispanic blacks; 29% of non-Hispanic black women had inadequate intakes.
- Total folate and folic acid intakes are highest for those aged over 50 y, and 5% exceed the Tolerable Upper Intake Level.
- No (with confidence) – for women of childbearing age and non-Hispanic black women
- Total folate is an umbrella term used to represent the different forms of the B vitamin.
- Folic acid supplementation in the periconceptional period decreases the occurrence of neural tube defects
