In the current study, the presence of detectable circulating folic acid is high, and its concentration is elevated compared with other populations. Age, smoking, lower concentration of vitamin B6 and genetic variant are associated with increased levels of circulating FA. Further researches are needed to acknowledge and guarantee the safety of exposure to folic acid, especially in countries which have mandatory fortification.
