According to a 2006 article by Florence Aslinia, M.D., and colleagues, published in the journal "Clinical Medicine & Research," if you are a person with a vitamin B12 deficiency caused by pernicious anemia, your serum folate levels will tend to be increased, presumably because the methionine synthase pathway -- methionine synthase is an enzyme in humans responsible for the production of methionine, an amino acid -- is impaired, allowing methyltetrahydrofolate, or the most common form of folate, to accumulate in your blood. Conversely, a longitudinal, population-based cohort of 35,059 pregnant Danish women and their children found no association between periconceptional folic acid or multivitamin use and ASD [53]. Am J Clin Nutr. One study included in the review among 709 women in Singapore found that compared with women with higher plasma folate concentrations (mean 40.4 nmol/L [17.8 ng/mL]) at 2628 weeks gestation, those with lower plasma folate concentrations (mean 27.3 nmol/L [12.0 ng/mL]) had a significantly higher risk of depression during pregnancy but not after giving birth [122]. Some, but not all, observational studies have shown associations between maternal use of folic acid and/or multivitamin supplements before and/or during pregnancy and lower risk of ASD in the womens offspring.
