A safe folic acid boost from flour
March 22, 2007Public consumption of folic acid from fortified flour at current mandated US levels (100micro-gram/day) and at double this amount is probably safe, at average intakes, according to an article published today in the open access journal BMC Public Health. The research has implications for the UK and Republic of Ireland, which plan to follow the US by adding folic acid to flour to help prevent neural tube defects in the near future.
Dr Mary Rose Sweeney and her colleagues from Trinity College Dublin commissioned a local bakery to bake three batches of bread, with different levels of folic acid. Single slices from the three batches contained 50micro-grams, 100micro-grams and 200micro-grams folic acid. The authors pre-saturated subjects first with daily 400micro-grams folic acid supplement, and subsequently tested them with a regime of two slices per day of the specially-prepared breads. Hourly blood tests determined whether folic acid was fully metabolised, and how long it remained in the blood.
Folic acid in bread at the 50micro-gram and 100micro-gram levels consumed twice with a 4-hour interval in between slices was fully metabolised each time. However a 400micro-gram supplement or 200micro-gram consumed once in a single slice of bread lead to metabolised folic acid in test subjects blood Long-term surveillance of the population is required to see whether folic acid accumulates, and to assess and potential safety implications.
Professor John Scott said: "this is good news in that it is possible to have optimum protection from a neural tube defect affected birth without having exposure to un-metabolised folic acid".
In fact the levels consumed currently in the US are thought to be in the range of 215-240micro-grams due to overage (the practice of adding a little extra to meet the mandate). Consumers may also get folic acid from other dietary sources, such as fortified cereals. The recommended dose for women of childbearing age in the UK is 400micro-grams per day.
Neural tube defects include spina bifida and anencephaly, which is fatal. Sufficient folic acid before and during pregnancy averts most neural tube defects. The neural tube develops in the first four weeks of pregnancy, often before many women know they are pregnant.

Anti-epilepsy drug risk on cognitive function for unborn children
Interim results of a study being conducted by scientists at the University of Liverpool suggest that children aged three years and younger, who are born to women taking the anti-epileptic drug sodium valproate whilst pregnant, are likely to have an IQ of six to nine points lower than average.
Irish-led research team rule out link between specific antibodies and spina bifida
New research, published today in the New England Journal of Medicine, shows that a woman's risk of having a child with a neural tube defect (NTD), such as Spina Bifida, is not linked to folic acid related auto-antibodies.

Some neural tube defects in mice linked to enzyme deficiency
Women of childbearing age can reduce the risk of having a child born with a neural tube defect such as spina bifida by eating enough folate or folic acid. However, folate prevents only about 70 percent of these defects.

Nature Made Folic Acid 600 mcg with DHA - 300 Softgels by Nature Made Folic acid, also known as folate and folacin, is essential in cell division, DNA synthesis, and the manufacturing of brain chemicals, or neurotransmitters in the body. Without adequate levels of folic acid, cells do not divide properly. Folic acid is vital to the development of the nervous system of a fetus. A deficiency of folic acid during pregnancy has been linked to several birth defects, such as the neural tube defect spina bifida. Therefore, it is critical for women of child-bearing age to consume 400 mcg of folic acid per day. In addition, folic acid may also play a significant role in heart health. It does so by helping to keep homocysteine levels down in the blood. Homocysteine is a substance that formed when Vitamin B12 and folic acid levels are low, and research has indicated... |

Ortho Molecular Products - Folic Acid 5 mg - 120 Capsules by Ortho Molecular Products For many seeking high doses of Folic Acid, a Folic supplement containing 5 mg has been previously available only through prescription, even though Folic has never been a pharmacy-only ingredient. A required component for the conversion of Homocysteine to methionine, Folic Acid supplementation reduces Homocysteine levels as demonstrated in many clinical studies. Regardless of initial Homocysteine levels, increased folic acid supplementation (up to 800 mcg) has been shown in research to enhance an increased Homocysteine lowering effect. Those with higher initial Homocysteine levels had greater lowering effects with Folic Acid. Low levels of daily Folic Acid intake have been associated with high serum Homocysteine levels, especially in the elderly. Current research is showing that aggressive... |
