The fortification program was expected to raise a person's folic acid intake level by 70–130 μg/day; however, an increase of almost double that amount was actually observed. This could be from the fact that many foods are fortified by 160–175% over the required amount. Much of the elder population take supplements that add 400 μg to their daily folic acid intake. This is a concern because 70–80% of the population have detectable levels of unmetabolized folic acid in their blood, a consequence of folic acid supplementation and fortification. However, at blood concentrations achieved via food fortification, folic acid has no known cofactor function that would increase the likelihood of a causal role for free folic acid in disease development.
