- This table illustrates mean total serum folate (μg/L) concentrations in a group of healthy adult subject (n = 19) exposed to a folic fortified bread for 1-week. Subject were pre-saturated with folic acid supplements for 14-weeks prior to the bread. The bread was fortified with 50 μg folic acid per slice, which was administered twice a day for seven days. The samples shown here were collected on the 7th day of bread consumption pre-prandially and post-prandially. Standard deviations and confidence intervals are also shown. Serum folic acid was not detectable at any sampling points
