Tudy, the bioavailability of B12 and folate, fasting and postprandially, was measured in 30 pregnant women for two prenatal multivitamin/multimineral supplements (Stuartnatal Plus and Materna, Wyeth-Ayerst Pharmaceuticals, Philadelphia, PA) and a placebo. The maximum postabsorption serum level was multiplied by the total body plasma levels to obtain the total rate of body absorption. The absorption peak of both vitamins occurred at 3 hours after ingestion of a supplement.
The total body absorption of the two vitamins was greater during fasting than it was postprandially. Similarly, there was 117% greater folate absorption fasting for Stuartnatal Plus (163 +/- 15 vs. 75 +/- 15 nmol, p < or = 0.001) and 57% greater absorption for Materna (207 +/- 21 vs. 132 +/- 13 nmol, p < or = 0.01). The absorption of both vitamins was significantly less when ingested after the test meal than when fastin.

S in pregnancy have adverse effects on fetal brain development with consequent impaired cognitive function in childhood. We therefore used the Avon Longitudinal Study of Parents and Children to test the hypothesis that cognitive outcomes in childhood are reduced if their mothers consumed a diet low in vitamin B12 during pregnancy. A detailed exposome analysis was used to identify 9 factors independently associated with low vitamin B12 intake.
These were taken into account in each of 26 outcome analyses. There were no such significant adjusted associations for reading or spelling abilities, or for verbal or full-scale IQ (Intelligence Quotient) at 8 or at 15. Thus, we have confirmed that there are adverse effects on the child’s development if the pregnant woman has a low intake of vitamin B12, and we have shown that these are specific to certain speech and mathematical abilitie.

However, it is unclear whether deficiencies of vitamin B12 prenatally are harmful to the developing fetus. These were taken into account in each of 26 outcome analyses.
Results showed that the children of women with the lowest 10% intake of B12 were at increased risk of poor vocabulary at 24 months, reduced ability at combining words at 38 months, poor speech intelligibility at 6 years, poor mathematics comprehension at school years 4 and 6 (ages 8-9 and 10-11 years), and poor results on the national mathematics tests (age 13). Thus, we have confirmed that there are adverse effects on the child’s development if the pregnant woman has a low intake of vitamin B12, and we have shown that these are specific to certain speech and mathematical abilitie.
