What is the Recommended Dietary Allowance for folate and folic acid for adults?
The Recommended Dietary Allowance (RDA) is the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97 to 98 percent) healthy individuals in each life-stage and gender group 10. The 1998 RDAs for folate and folic acid are expressed in a term called the Dietary Folate and Folic Acid Equivalent. The Dietary Folate and (Folic Acid) Equivalent (DFE) was developed to help account for the differences in absorption of naturally occurring dietary folate and the more bioavailable synthetic folic acid11.
