Folic acid fortification and public health: Report on threshold doses above which unmetabolised folic acid appear in serum

Table 1 Mean red cell (μg/L) and serum folate (μg/L) concentrations at recruitment (n = 19).

This table illustrates mean baseline red cell (μg/L) and total serum folate concentrations (μg/L) at recruitment (n = 19). No subjects had detectable serum folic acid at baseline (>0.312 μg/L).
Normal reference range for red cell folate is in the range of 150–1000 μg/L and for total serum folate is 2.7–20 μg/L
