How do you calculate dietary folate?
Method for calculating folic acid intake taking into account the lower availability of mixed folates in food compared with synthetic tetrahydrofolate used in food enrichment and supplements. 1 µg DFE = 1 µg food folate or 0.6 µg synthetic folate; total DFE = µg food folate + 1.7 times µg synthetic folate.
Why is there a unit of measure for folate known as dietary folate equivalent DFE )?
The measure of mcg DFE is used because the body has an easier time absorbing folic acid than folate. A %DV is shown for the total amount of folate in a product, and if any of the total folate comes from folic acid, that amount of folic acid is listed in mcg in parentheses.

Vitamin B12 is an especially important vitamin for maintaining healthy nerve cells, and it helps in the production of DNA and RNA, the body’s genetic material. Vitamin B12 works closely with vitamin B9, also called folate or folic acid, to help make red blood cells and to help iron work better in the body.
How much folate is equivalent to folic acid?
Folic acid can be measured in mcg DFE or in mcg (1.67 mcg DFE is the same as 1 mcg of folic acid). Based on this, to prevent anemia, women who are not pregnant or breastfeeding should consume 400 mcg DFE (100% daily value (DV) for folate), which is equal to 240 mcg folic acid.
