A member of the vitamin B family that stimulates the hematopoietic system. It is present in the liver and kidney and is found in mushrooms, spinach, yeast, green leaves, and grasses (POACEAE). Folic acid is used in the treatment and prevention of folate deficiencies and megaloblastic anemia.
A nutritional condition produced by a deficiency of FOLIC ACID in the diet. Many plant and animal tissues contain folic acid, abundant in green leafy vegetables, yeast, liver, and mushrooms but destroyed by long-term cooking. Alcohol interferes with its intermediate metabolism and absorption. Folic acid deficiency may develop in long-term anticonvulsant therapy or with use of oral contraceptives. This deficiency causes anemia, macrocytic anemia, and megaloblastic anemia. It is indistinguishable from vitamin B 12 deficiency in peripheral blood and bone marrow findings, but the neurologic lesions seen in B 12 deficiency do not occur. (Merck Manual, 16th ed)
Congenital malformations of the central nervous system and adjacent structures related to defective neural tube closure during the first trimester of pregnancy generally occurring between days 18-29 of gestation.

Condition in which the plasma levels of homocysteine and related metabolites are elevated (>13.9 µmol/l). Hyperhomocysteinemia can be familial or acquired. Development of the acquired hyperhomocysteinemia is mostly associated with vitamins B and/or folate deficiency (e.g., PERNICIOUS ANEMIA, vitamin malabsorption). Familial hyperhomocysteinemia often results in a more severe elevation of total homocysteine and excretion into the urine, resulting in HOMOCYSTINURIA. Hyperhomocysteinemia is a risk factor for cardiovascular and neurodegenerative diseases, osteoporotic fractures and complications during pregnancy.

VITAMIN B 6 refers to several PICOLINES (especially PYRIDOXINE; PYRIDOXAL; & PYRIDOXAMINE) that are efficiently converted by the body to PYRIDOXAL PHOSPHATE which is a coenzyme for synthesis of amino acids, neurotransmitters (serotonin, norepinephrine), sphingolipids, and aminolevulinic acid. During transamination of amino acids, pyridoxal phosphate is transiently converted into PYRIDOXAMINE phosphate. Although pyridoxine and Vitamin B 6 are still frequently used as synonyms, especially by medical researchers, this practice is erroneous and sometimes misleading (EE Snell; Ann NY Acad Sci, vol 585 pg 1, 1990). Most of vitamin B6 is eventually degraded to PYRIDOXIC ACID and excreted in the urine.
Derivatives of folic acid (pteroylglutamic acid). In gamma-glutamyl linkage they are found in many tissues. They are converted to folic acid by the action of pteroylpolyglutamate hydrolase or synthesized from folic acid by the action of folate polyglutamate synthetase. Synthetic pteroylpolyglutamic acids, which are in alpha-glutamyl linkage, are active in bacterial growth assays.
A nutritional condition produced by a deficiency of VITAMIN B 12 in the diet, characterized by megaloblastic anemia. Since vitamin B 12 is not present in plants, humans have obtained their supply from animal products, from multivitamin supplements in the form of pills, and as additives to food preparations. A wide variety of neuropsychiatric abnormalities is also seen in vitamin B 12 deficiency and appears to be due to an undefined defect involving myelin synthesis.

Thiamine deficiency is prevalent in a selected group of urban Indonesian elderly people. (1/4015)

This cross-sectional study involved 204 elderly individuals (93 males and 111 females). Subjects were randomly recruited using a list on which all 60-75 y-old-people living in seven sub-villages in Jakarta were included. The usual food intake was estimated using semiquantitative food frequency questionnaires. Hemoglobin, plasma retinol, vitamin B-12, red blood cell folate and the percentage stimulation of erythrocyte transketolase (ETK), as an indicator of thiamine status, were analyzed. Median energy intake was below the assessed requirement. More than 75% of the subjects had iron and thiamine intakes of approximately 2/3 of the recommended daily intake, and 20.2% of the study population had folate intake of approximately 2/3 of the recommended daily intake. Intakes of vitamins A and B-12 were adequate. Biochemical assessments demonstrated that 36.6% of the subjects had low thiamine levels (ETK stimulation > 25%). The elderly men tended to have lower thiamine levels than the elderly women. The overall prevalence of anemia was 28.9%, and the elderly women were affected more than the elderly men. Low biochemical status of vitamins A, B-12 and RBC folate was found in 5.4%, 8.8 % and 2.9% of the subjects, respectively. Dietary intakes of thiamine and folate were associated with ETK stimulation and plasma vitamin B-12 concentration (r = 0.176, P = 0.012 and r = 0.77, P = 0.001), respectively. Results of this study suggest that anemia, thiamine and possibly vitamin B-12 deficiency are prevalent in the elderly living in Indonesia. Clearly, micronutrient supplementation may be beneficial for the Indonesian elderly population living in underprivileged areas.  (+info)

Plasma total homocysteine and cysteine in relation to glomerular filtration rate in diabetes mellitus. (2/4015)

BACKGROUND: The plasma concentrations of total homocysteine (tHcy) and total cysteine (tCys) are determined by intracellular metabolism and by renal plasma clearance, and we hypothesized that glomerular filtration is a major determinant of plasma tHcy and tCys. We studied the relationships between the glomerular filtration rate (GFR) and plasma tHcy and tCys in populations of diabetic patients with particularly wide ranges of GFR. METHODS: We measured GFR, urine albumin excretion rate (UAER), plasma tHcy, tCys, methionine, vitamin B12, folate, C-peptide, and routine parameters in 50 insulin-dependent diabetes mellitus (IDDM) and 30 non-insulin-dependent diabetes mellitus (NIDDM) patients. All patients underwent intensive insulin treatment and had a serum creatinine concentration below 115 micromol/liter. RESULTS: Mean plasma tHcy in diabetic patients (0.1 micromol/liter) was lower than in normal persons (11.1 micromol/liter, P = 0.0014). Mean plasma tCys in diabetic patients (266.1 micromol/liter) was also lower than in normal persons (281.9 micromol/liter, P = 0.0005). Seventy-three percent of the diabetic patients had relative hyperfiltration. Plasma tHcy and tCys were closely and independently associated with GFR, serum folate, and serum B12. However, plasma tHcy was not independently associated with any of the 22 other variables tested, including age, serum creatinine concentration, UAER, total daily insulin dose, and glycemic control. CONCLUSIONS: Glomerular filtration rate is an independent determinant of plasma tHcy and tCys concentrations, and GFR is rate limiting for renal clearance of both homocysteine and cysteine in diabetic patients without overt nephropathy. Declining GFR explains the age-related increase in plasma tHcy, and hyperfiltration explains the lower than normal mean plasma tHcy and tCys concentrations in populations of diabetic patients.  (+info)

Effect of MTHFR 677C>T on plasma total homocysteine levels in renal graft recipients. (3/4015)

BACKGROUND: Hyperhomocysteinemia is an established, independent risk factor for vascular disease morbidity and mortality. The 5,10-methylenetetrahydrofolate reductase (MTHFR) gene polymorphism C677T has been shown to result in increased total homocysteine concentrations on the basis of low folate levels caused by a decreased enzyme activity. The effect of this polymorphism on total homocysteine and folate plasma levels in renal transplant patients is unknown. METHODS: We screened 636 kidney graft recipients for the presence of the MTHFR C677T gene polymorphism. The major determinants of total homocysteine and folate plasma concentrations of 63 patients, who were identified to be homozygous for this gene polymorphism compared with heterozygotes (N = 63), and patients with wild-type alleles (N = 63), who were matched for sex, age, glomerular filtration rate (GFR), and body mass index, were identified by analysis of covariance. The variables included sex, age, GFR, body mass index, time since transplantation, folate and vitamin B12 levels, the use of azathioprine, and the MTHFR genotype. To investigate the impact of the kidney donor MTHFR genotype on total homocysteine and folate plasma concentrations, a similar model was applied in 111 kidney graft recipients with stable graft function, in whom the kidney donor C677T MTHFR gene polymorphism was determined. RESULTS: The allele frequency of the C677T polymorphism in the MTHFR gene was 0.313 in the whole study population [wild-type (CC), 301; heterozygous (CT), 272; and homozygous mutant (TT), 63 patients, respectively] and showed no difference in the patient subgroups with various renal diseases. The MTHFR C677T gene polymorphism significantly influenced total homocysteine and folate plasma concentrations in renal transplant recipients (P = 0.0009 and P = 0.0002, respectively). Furthermore, a significant influence of the GFR (P = 0.0001), folate levels (P = 0.0001), age (P = 0.0001), body mass index (P = 0.0001), gender (P = 0.0005), and vitamin B12 levels (P = 0.004) on total homocysteine concentrations was observed. The donor MTHFR gene polymorphism had no influence on total homocysteine and folate levels. Geometric mean total homocysteine levels in patients homozygous for the mutant MTHFR allele were 18.6 micromol/liter compared with 14.6 micromol/liter and 14.9 micromol/liter in patients heterozygous for the MTHFR gene polymorphism and those with wild-type alleles (P < 0.05 for TT vs. CT and CC). Geometric mean folate levels were lower in CT and TT patients (11.2 and 10.2 nmol/liter) compared with CC patients (13.6 nmol/liter, P < 0.05 vs. CT and TT). CONCLUSIONS: This study demonstrates that homozygosity for the C677T polymorphism in the MTHFR gene significantly increases total homocysteine concentrations and lowers folate levels in kidney graft recipients, even in patients with excellent renal function (GFR more than median). These findings have important implications for risk evaluation and vitamin intervention therapy in these patients who carry an increased risk for the development of cardiovascular disease.  (+info)

Endothelial dysfunction by acute hyperhomocyst(e)inaemia: restoration by folic acid. (4/4015)

Recent evidence demonstrates that hyperhomocyst(e)inaemia is a novel risk factor for cardiovascular diseases. In patients with chronic hyperhomocyst(e)inaemia, endothelial function is impaired. However, whether hyperhomocyst(e)inaemia per se is a cause or an epiphenomenon of endothelial dysfunction remains unknown. In this study, we examined the effects of methionine-induced acute hyperhomocyst(e)inaemia on human endothelial function. In healthy volunteers we administered methionine (0.1 g/kg body weight, per os), a substrate of homocyst(e)ine, with or without folic acid (20 mg, per os) and examined flow-mediated vasodilatation of the brachial artery by high-resolution ultrasonography as a non-invasive measure of endothelial function. We also measured plasma levels of homocyst(e)ine before and 3, 8 and 24 h after methionine loading. Methionine administration increased plasma levels of homocyst(e)ine by four times the basal level at 8 h (P<0.0001, ANOVA). The plasma levels returned to baseline at 24 h. Flow-mediated vasodilatation was significantly decreased to half of the baseline value at 8 h and returned to baseline at 24 h (P<0.0001, ANOVA), whereas endothelium-independent vasodilatation by glyceryl trinitrate was not affected by the methionine loading. Co-administration of folic acid did not attenuate methionine-induced hyperhomocyst(e)inaemia but completely prevented endothelial dysfunction. Our results suggest that in humans a methionine-rich diet may acutely impair endothelial function, which can be prevented by folic acid supplementation.  (+info)

Influence of haemodialysis on plasma total homocysteine concentration. (5/4015)

BACKGROUND: The high prevalence of hyperhomocysteinaemia in uraemic patients is of interest because of the cardiovascular risk associated with increased plasma total homocysteine (tHcy) concentration. Treatment with folic acid lowers tHcy in haemodialysis patients, however, in most patients not to normohomocysteinaemic levels. With possible tHcy-lowering modifications in mind, we studied the influence of standard haemodialysis on tHcy. METHODS: In 56 folate-loaded haemodialysis patients, tHcy and parameters of dialysis adequacy were measured. In six patients, interdialytic curves of tHcy and serum creatinine concentrations were obtained and in five patients, the amount of homocysteine (Hcy) in dialysate was determined. RESULTS: tHcy (21.8+/-14.4 micromol/l) correlated significantly with Kt/V (r=0.32, P<0.05), total Kt/V (r=0.29, P<0.05), nPCR (r=0.30, P<0.05) and serum concentrations of albumin (r=0.28, P<0.05) and cobalamines (r=-0.27, P<0.05). In a multiple linear regression analysis, only serum albumin concentrations significantly predicted tHcy (r=0.34, P < 0.05). During dialysis, tHcy decreased by 28% and remained constant for at least 8 h after treatment. The amount of Hcy recovered in dialysate was 63 micromol (12-158 micromol). There was no difference in tHcy between those who had residual renal function and those who had not. CONCLUSIONS: The direct relationship between tHcy and Kt/V seemed to be mediated by the serum albumin concentration. The shape of the interdialytic tHcy curve suggested facilitated Hcy removal for at least 8 h after dialysis possibly due to reduced levels of inhibitory activities against relevant enzyme(s). The dialysed amount of Hcy did not seem to contribute significantly to Hcy removal. Thus, modifications of standard dialytic regimens are not likely to be effective from a tHcy-lowering point of view whereas convective procedures such as haemofiltration or haemodiafiltration might be more effective.  (+info)

An estimation of the requirement for folic acid in gestating sows: the metabolic utilization of folates as a criterion of measurement. (6/4015)

Sows at their second parity were randomly distributed in five groups of seven animals each to determine the dietary concentration of folic acid that optimizes the metabolic utilization of the vitamin during gestation. The groups differed by dietary supplement of folic acid: 0, 5, 10, 15, or 20 ppm. Sows were fed 2.5 kg of diet each day. The response of serum folates and folate binding capacity to treatments and the excretion of urinary folates after an i.v. injection of folic acid were measured. The total daily excretion of urinary folates was corrected according to the response to one i.v. injection of saline on the day preceding the i.v. injection of folic acid. The decrease of total serum folates throughout gestation was less pronounced in the groups fed 15 and 20 ppm of dietary folic acid (supplement x period interaction, P<.06) than it was in the other three treatments. The proportion of i.v. folic acid not recovered in sow urine (injected - excreted) decreased as the amount of dietary folic acid increased to reach a minimum, which differed according to the period (supplement x period interaction, P<.02); it was 15 ppm during wk 1 of gestation and 10 ppm for the other periods studied. The unrecovered folates increased over a dietary concentration of 15 ppm. These minimum values correspond to the most appropriate feed concentration that covered the whole body utilization (tissue and cell metabolism, catabolism, and storage) of folates by the sows and could be interpreted as a reliable index of the requirement.  (+info)

MTHFR polymorphism, methyl-replete diets and the risk of colorectal carcinoma and adenoma among U.S. men and women: an example of gene-environment interactions in colorectal tumorigenesis. (7/4015)

Our studies on interactions of a folate-metabolizing gene polymorphism and dietary intake in colorectal tumorigenesis demonstrate the potential importance of studying interactions between genotype and environmental exposure in relation to cancer risk. We observed an inverse association of a polymorphism (667C --> T, ala --> val) in the methylenetetrahydrofolate reductase (MTHFR) gene with colorectal cancer but not with colorectal adenomas. The inverse association of methionine and adverse association of alcohol with colorectal cancer were stronger among val/val individuals. These interactions were not present in studies of colorectal adenomas. Our studies illustrate that studying gene-environment interactions in relation to cancer can be of importance in clarifying cancer etiology as well as pointing to preventive dietary modifications.  (+info)

Hyperhomocyst(e)inaemia in children with chronic renal failure. (8/4015)

BACKGROUND: Hyperhomocyst(e)inaemia has been identified as a significant risk factor for the occurrence of atherosclerosis in adults with chronic renal failure. Because of its presumed direct toxic effect on the vascular wall, long-standing hyperhomocyst(e)inaemia in children with chronic renal failure might have an important influence on their risk of future development of atherosclerosis. Hitherto no data on hyperhomocyst(e)inaemia in children with renal failure have been published. METHODS: We investigated 16 children with chronic renal failure on conservative management, 12 children on haemodialysis and 17 children with a renal transplant. Age-matched controls were used for comparison. Plasma homocyst(e)ine levels after an overnight fast were determined by HPLC. Glomerular filtration rate was estimated by the Schwartz formula. RESULTS: Mean plasma homocyst(e)ine levels were 12.6 +/- 5.2 micromol/l in the conservatively managed group, 22.2 +/- 13.5 micromol/l in the haemodialysed group, 14.2 +/- 2.1 micromol/l in transplanted children with an estimated GFR > 60 ml/min/1.73 m2 and 17.5 +/- 5.1 micromol/l in transplanted children with a lower estimated GFR. In all groups homocyst(e)ine levels were significantly elevated as compared to controls. Homocyst(e)ine levels were significantly correlated with age and negatively correlated with estimated GFR and serum folate levels. CONCLUSIONS: Hyperhomocyst(e)inaemia is a feature of chronic renal failure in children as well as in adults. Elevated homocyst(e)ine levels can already be demonstrated in children with renal failure before end-stage renal disease has developed and persist after renal transplantation. Whether treatment of hyperhomocyst(e)inaemia in children with renal failure decreases the risk for future atherosclerosis remains to be proven.  (+info)

The Food and Drug Administration mandated that by 1998, all enriched cereal grain products (ECGP) be fortified with folic acid in order to prevent the occurrence of neural tube defects. The Institute of Medicine established the tolerable upper intake level (UL) for folic acid (1000 µg/day for adults) in 1998. We characterized U.S. adults with usual daily folic acid intake exceeding the UL. Using NHANES 2003-2010 data, we estimated the percentage of 18,321 non-pregnant adults with usual daily folic acid intake exceeding the UL, and among them, we calculated the weighted percentage by sex, age, race/ethnicity, sources of folic acid intake, supplement use and median usual daily folic acid intakes. Overall, 2.7% (standard error 0.6%) of participants had usual daily intake exceeding the UL for folic acid; 62.2% were women; 86.3% were non-Hispanic whites; and 98.5% took supplements containing folic acid. When stratified by sex and age groups among those with usual daily folic acid intake exceeding ...
Periconceptional supplementation with folic acid - the synthetic form of the B-vitamin folate - reduces the occurrence of adverse pregnancy outcomes such as spina bifida. The underlying biochemical mechanisms for how folic acid affects health outcomes however are unknown. The naturally occurring form 5-methyltetrahydrofolate (5-MTHF) is now available and discussed as an adequate substitute to folic acid. This study aims to determine the effect of folic acid compared to 5-MTHF on cellular mechanisms. Stable isotope tracer protocols will be used that allow determining the effect of folic acid on the dynamics of metabolic pathways in the human body.. Hypothesis: Supplementation with high-dose folic acid alters the turnover rate of folate dependent pathways in healthy humans; but 5-MTHF does not. Genetic variations in a key enzyme of the folate metabolism will aggravate the effect of folic acid on the metabolic pathways. ...
Background: Additional folic acid treatment appears to have a neutral effect on reducing vascular risk in countries that mandate fortification of food with folic acid (e.g. US and Canada). However, it is uncertain whether folic acid therapy reduces stroke risk in countries without folic acid food fortification.. Objective: To comprehensively evaluate the efficacy of folic acid therapy on stroke prevention in countries without folic acid food fortification.. Methods: Pubmed, EMBASE, and Clinicaltrials.gov from January 1966 to August 2015 were searched to identify relevant studies. Relative risk (RR) with 95% CI was used as a measure of the association between folic acid supplementation and risk of stroke, after pooling data across trials in a random-effects model.. Results: The search identified 14 randomized controlled trials involving treatment with folic acid that had enrolled 71,334 participants, all of which stroke was reported as an outcome measure. Across all trials, folic acid therapy vs. ...
BACKGROUND: Taking folic acid supplements before pregnancy to reduce the risk of a neural tube defect (NTD) is especially important in countries without universal folic acid fortification. The extent of folic acid supplementation among women who had antenatal screening for Downs syndrome and NTDs at the Wolfson Institute of Preventive Medicine, London between 1999 and 2012 was assessed. METHODS AND FINDINGS: 466,860 women screened provided details on folic acid supplementation. The proportion of women who took folic acid supplements before pregnancy was determined according to year and characteristics of the women. The proportion of women taking folic acid supplements before pregnancy declined from 35% (95% CI 34%-35%) in 1999-2001 to 31% (30%-31%) in 2011-2012. 6% (5%-6%) of women aged under 20 took folic acid supplements before pregnancy compared with 40% of women aged between 35 and 39. Non-Caucasian women were less likely to take folic acid supplements before pregnancy than Caucasian women; ...
To better understand the effects of folic acid supplements on the body, British researchers reviewed the results of all large randomized studies through 2010 that included folic acid supplements. The combined studies had about 50,000 participants.. From their analysis, researchers found that taking a daily folic acid supplement for up to five years didnt increase a persons risk for cancer. Taking these supplements even longer and at higher doses also seemed to show no significant rise in cancer risk. In fact, people who took folic acid supplements daily were just as likely to be diagnosed with cancer as those who did not take them.. And some studies suggest that folic acid may help prevent cancer, particularly colorectal cancer. But more research is needed to verify this link..

Women of childbearing age, people who abuse alcohol, anyone taking anti-convulsants or other medications that interfere with the action of folate or folic acid, individuals diagnosed with anemia from folate or folic acid deficiency, and individuals with malabsorption, liver disease, or who are receiving kidney dialysis treatment may benefit from a folic acid supplement. Folic acid is very important for all women who may become pregnant. Adequate folate and folic acid intake during the periconceptual period, the time just before and just after a woman becomes pregnant, protects against a number of congenital malformations including neural tube defects21. Neural tube defects result in malformations of the spine (spina bifida), skull, and brain (anencephaly)10. The risk of neural tube defects is significantly reduced when supplemental folic acid is consumed in addition to a healthful diet prior to and during the first month following conception5, 22, 23. Women who could become pregnant are advised ...

If youre pregnant or even planning to get pregnant, taking folic acid will help prevent serious birth defects in your baby. But what is folic acid? And how do you get it into your diet? As part of Folic Acid Awareness Week, ACCESS is shedding light on this essential supplement for women and babies.. What is folic acid?. To understand folic acid, lets start with folate. Folate is a form of vitamin B that helps cells in your body grow and develop normally. Folic acid is the synthetic man-made form of folate. Folic acid: why its important. It wasnt until the 1980s when researchers discovered that taking folic acid during pregnancy helped prevent brain and spine defects like spina bifida and anencephaly. Since then, its been considered an essential supplement for pregnant women. Because a lot of important brain growth happens in the first weeks before women know theyre pregnant, its recommended that all women of childbearing age (15-45) take folic acid, even if they dont plan on becoming ...
Folic acid (also called folate, folacin, or vitamin B9) is a vitamin that helps grow and protect cells. While folic acid is found is some foods, including fortified grains, lentils, chickpeas, oranges, brussel sprouts, and spinach, it is difficult to get enough folic acid from your diet alone.. Research shows that taking folic acid (in the pill form from the pharmacy) in the three months before pregnancy, can lower the risk of some birth defects, including open spinal cord (neural tube defect), facial clefts, congenital heart disease, limb defects, urinary tract problems, and some paediatric cancers. It is important that all women of child-bearing age take between 0.4 - 1.0mg of folic acid daily. At minimum, you should begin taking a folic acid supplement three months before trying to get pregnant, but because many pregnancies are unplanned, all women who could become pregnant should take a supplement daily. Talk to your health care provider about whether you are taking the right dose for you. ...

Study design was genotype-stratified, randomized, double-blind, placebo-controlled trials. The setting was a Japanese company in the chemical industry. Subjects were 203 healthy men after exclusion of those who took folic acid or drugs known to effect folic acid metabolism. Intervention was folic acid 1 mg/day p.o. for 3 months. The primary endpoint was plasma total homocysteine level (tHcy). In all three genotypes, there were ...
A study in Pediatrics suggests that pregnant women who eat grain products fortified with folic acid may also be helping to decrease some types of childhood cancer. Nutrients such as folic acid and other vitamins are commonly added to products we buy at the store such as bread and cereal-a process referred to as fortification.. To explore whether kids born to women exposed to folic acid-fortified food sources have lower cancer risk, researchers looked at the incidence of childhood cancers in kids up to four years old during the time period before food was fortified with folic acid and after 1996 when the US Food and Drug Administration required that all enriched grain products be fortified with folic acid.. Results showed that the rates of certain types of childhood cancers did, in fact, decrease after folic acid was added to foods, including the rates of Wilms tumors, which affect the kidney; primitive neuroectodermal tumors that affect the nervous system; and ependymomas, which affect the brain ...
Folic acid, folate, or vitamin B-9, is a water-soluble vitamin. It plays an important part in cell division and in making cells in the blood-forming organs and bone marrow. It also plays a role in the development of the fetal spinal cord during pregnancy. Like the other B vitamins, folic acid plays an important role in energy production. The body converts folic acid to tetrahydrofolic acid. Tetrahydrofolic acid plays an important part in cell division. Its involved in nucleic acid (DNA and RNA) synthesis. Folic acid deficiency causes larger-than-normal red blood cells and other abnormalities in white and red blood cells. This is called macrocytic anemia. Research suggests that folic acid supplements can reduce the incidence of neural tube defects (spina bifida) in newborn infants by up to 50%. For this reason, the National Institutes of Health and Centers for Disease Control and Prevention recommend that women of childbearing age take a minimum of 400 micrograms (mcg) of folic acid per day. To ...
A questionnaire was self administered by consenting women, attending three hospital-based antenatal clinics within the West Midlands region of the United Kingdom, who also provided a blood sample.4 Three questions assessed the use of folic acid supplements: (1) Have you taken folic acid at any point before or during this pregnancy? (2) Did you take folic acid before you got pregnant? (3) Are you taking folic acid at this moment? The questionnaires were administered during 1996-97 and also collected demographic and dietary information. Serum and red cell folate (RCF) measurements were made at a single laboratory with a standard test (BIO-RAD Quantaphase II B12/Folate radioassay) to minimise measurement error. The laboratory was blinded to patients use of folic acid supplements to avoid any bias. Data were reported by the laboratory in conventional units (μg/l) and converted to SI units (nmol/l) by multiplying by a conversion factor of 2.266.. The combinations of yes/no responses to the ...
CONTEXT: Blood homocysteine levels are positively associated with cardiovascular disease, but it is uncertain whether the association is causal. OBJECTIVE: To assess the effects of reducing homocysteine levels with folic acid and vitamin B(12) on vascular and nonvascular outcomes. DESIGN, SETTING, AND PATIENTS: Double-blind randomized controlled trial of 12,064 survivors of myocardial infarction in secondary care hospitals in the United Kingdom between 1998 and 2008. INTERVENTIONS: 2 mg folic acid plus 1 mg vitamin B(12) daily vs matching placebo. MAIN OUTCOME MEASURES: First major vascular event, defined as major coronary event (coronary death, myocardial infarction, or coronary revascularization), fatal or nonfatal stroke, or noncoronary revascularization. RESULTS: Allocation to the study vitamins reduced homocysteine by a mean of 3.8 micromol/L (28%). During 6.7 years of follow-up, major vascular events occurred in 1537 of 6033 participants (25.5%) allocated folic acid plus vitamin B(12) vs 1493 of

Methods 36 healthy 6-week-old Wistar male rats, weighing (160±10 g), after being fed adaptable for one week, were randomly divided into control group (n=12), Hhcy group (n=12), folic acid treatment group (n=12). The control group was fed with AIN-93G diet. The Hhcy group was fed with high-methionion diet, consisting of AIN-93G diet plus 1.7% methionion. The folic acid treatment group was fed with high-methionion plus folic acid-rich diet, consisting of AIN-93G diet plus 1.7% methionion and 0.008% folic acid. After be maintained for 18 weeks on the previously described diets, the Hcy and folic acid concentrations in the plasma was measured with the IMX assays. The thoracic aorta was harvested for morphology (electron microscopy). The DNA methyltransferase activity was determined using EpiQuik DNA Methyltransferase (DNMT) Activity/Inhibition Assay Kit. The methylation status of LINE-1 was assessed by the combined bisulphite restriction analysis (COBRA) method.. ...
Increased total plasma homocysteine concentration is an independent risk factor for premature atherosclerosis. Elevated levels of homocysteine may reflect low levels of folate, decreased vitamin B12 or vitamin B6 levels, or inherited abnormalities of certain essential enzymes. Folic acid in dosages of 1 to 10 mg can lower homocysteine levels. Lobo and associates studied a combination of daily low-dose folic acid supplement combined with vitamins B12 and B6 to reduce homocysteine levels in patients with coronary artery disease.. Ninety-five patients with coronary artery disease were nonrandomly assigned to one of four groups: placebo, 400 μg of folic acid, 1 mg of folic acid or 5 mg of folic acid daily. Patients receiving supplemental folic acid also received additional vitamin B6 (12.5 mg) and vitamin B12 (500 μg) daily. Treatment was administered for 90 days. Homocysteine, folate, vitamin B12 and vitamin B6 levels were determined before enrollment in the study and at 30 or 90 days after ...
In this study, maternal and postweaning folic acid supplementation at the level equivalent to the average postfortification total folate intake in North America significantly increased the incidence of mammary adenocarcinomas in the offspring. Furthermore, maternal folic acid supplementation significantly accelerated the development of mammary adenocarcinomas and increased the multiplicity of mammary adenocarcinomas in the offspring, whereas a nonsignificant trend toward the same effects was observed for postweaning folic acid supplementation. No significant interaction between maternal and postweaning folic acid supplementation was observed for any of the tumor endpoints in the offspring. The mammary tumor promoting effect was more consistent and greater with maternal folic acid supplementation than with postweaning supplementation.. We posited that maternal and postweaning folic acid supplementation would increase global DNA methylation in the offspring, thereby reducing the risk of developing ...
Folic acid is a B vitamin that promotes cell growth and helps prevent certain birth defects. It is Folic Acid Awareness Week - a great time to become familiar with how this vitamin can help you and your baby.. Your body needs to make new cells every day for blood, skin, hair and nails. Folic acid also plays an important role in helping red blood cells carry oxygen from your lungs to all parts of your body.. How can folic acid help your baby?. Folic acid helps prevent birth defects of the brain and spine, called neural tube defects, if taken before pregnancy and during the first few weeks of pregnancy. So it is helpful to get in the habit of taking a multi-vitamin with at least 400 micrograms of folic acid every day, before you become pregnant.. Even if you are not planning to become pregnant, your body needs folic acid for normal growth and development.. What if youre already pregnant?. Most pregnant women need to take a multi-vitamin with 600 micrograms of folic acid. Talk with your prenatal ...
Association between low-dose folic acid supplementation and blood lipids concentrations in male and female subjects with atherosclerosis risk factors - Order reprints #889087
The concentration of folate in erythrocytes was determined using a two-phase ligand-binding radioassay procedure described previously for measuring serum folate. The mean (± SD) folate concentration in erythrocytes of 20 normal subjects was 210 ± 57 ng/ml. In 12 patients clinically folate deficient who had normal serum B12 concentration, the mean (± SD) erythrocyte folate was 71 ± 39 ng/ml. Incubation of the lysed erythrocytes for 2 hr prior to boiling increased the radioassayable folate. The radioassayable folate decreased rapidly if the whole blood was stored at 4°C without ascorbate. Extracts of blood prepared with ascorbate could be stored at -20°C for several days. The radioassayable concentration of erythrocyte folate was similar to the values obtained using Lactobacillus casei when the concentration was 200 ng/ ml or less. With values higher by L. casei, the radioassayable folate was significantly lower even though the normal and folate-deficient groups were distinctly separated. ...
Short-term use of folic acid supplements is unlikely to increase peoples risk of developing cancer, new research has shown.. Scientists at the University of Oxford looked at previous trials of folic acid supplementation, involving almost 50,000 people.. Overall, they found that people who took daily folic acid supplements for five years or less - up to around 40mg per day - did not have a significant increase in their risk of developing cancer, compared with those who took a placebo (dummy treatment).. There was also no significant increase in the risk of specific forms of the disease, including bowel, lung, breast and prostate cancers.. Lead author Dr Robert Clarke, whose findings are published in the Lancet medical journal, said: The study provides reassurance about the safety of folic acid intake, either from supplements or through fortification, when taken for up to five years.. However, longer studies are needed to shed light on the effects of longer-term supplementation.. Folic acid ...
Importance: Presently, 81 countries mandate the fortification of grain products with folic acid to lessen the risk of neural tube defects in the developing fetus. Epidemiologic data on severe mental illness suggest potentially broader effects of prenatal folate exposure on postnatal brain development, but this link remains unsubstantiated by biological evidence.Objective: To evaluate associations among fetal folic acid exposure, cortical maturation, and psychiatric risk in youths.Design, Setting, and Participants: A retrospective, observational clinical cohort study was conducted at Massachusetts General Hospital (MGH) among 292 youths 8 to 18 years of age born between January 1993 and December 2001 (inclusive of folic acid fortification rollout ±3.5 years) with normative results of clinical magnetic resonance imaging, divided into 3 age-matched groups based on birthdate and related level of prenatal folic acid fortification exposure (none, partial, or full). Magnetic resonance imaging was ...

These observations do not prove a causal link between folic acid fortification and increased rates of CRC in North America in the mid-1990s. Whether the increased rate of CRC between 1996 and 2000 was due to the institution of folic acid fortification is a matter of speculation based on a temporal association between the two phenomena and a supportive literature that indicates that high intake of folic acid can accelerate the growth of established neoplasms. Because it is estimated that 35% to 50% of Americans over the age of 50 years harbor one or more colorectal adenomas (33) and that the vast majority of these growths lack any associated signs or symptoms, we suggest that the addition of substantial quantities of folic acid into the food supply in the mid-1990s may have facilitated the transformation of adenomas into cancers, or small cancers into larger ones: in each instance this would make the lesions more evident at the time of a routine screening colonoscopy. In addition, accelerating ...
Folic acid reduced risk for heart disease, stroke and cut birth defects in children whose mothers had adequate levels of this essential nutrient. In a heart study, researchers recruited 46 men and women with coronary artery disease and high levels of homocysteine, a risk factor for the illness. Some participants also had a genetic defect (T-allele) that raises homocysteine. After eight weeks of taking 400 mcg of folic acid per day or a placebo, those in the folic acid group had lower homocysteine levels and homocysteine decreased most in those with T-allele. In a stroke study, researchers analyzed eight recent clinical trials and found that compared to those who had not taken folic acid, those who had were 18% less likely to have a stroke. Those who had taken folic acid for more than 36 months were 29% less likely to have a stroke. Researchers concluded that folic acid can prevent stroke. In a birth defect study published in the New England Journal of Medicine, researchers tracked 1.9 million ...
Deficiencies in nutrients such as folic acid and vitamin B12 may play a role in fetal growth restriction (FGR). However, whether folic acid, vitamin B12, or homocysteine is associated with FGR in Chinese populations remains unclear. This study investigated the relationship between these nutrient deficiencies and FGR in pregnant Chinese women. We selected 116 mother and infant pairs, and categorized the neonates into the FGR, appropriate for gestational age, and large for gestational age groups. Birth weight, body length, head circumference, body mass index (BMI), and Rohrers body index of the newborns were measured. Serum folic acid, vitamin B12, and homocysteine levels were measured in mothers during the first three days of their hospital stay. Results showed that the FGR group exhibited reduced folic acid and vitamin B12 levels and elevated homocysteine levels than those in the other two groups. Folic acid and vitamin B12 levels were positively correlated with birth weight, head ...
Emerging evidence has suggested that folic acid-containing multivitamins may markedly reduce the risk of gestational hypertension or preeclampsia. We examined whether maternal supplementation with folic acid alone during early pregnancy can prevent the occurrence of gestational hypertension and preeclampsia. The data are from a large population-based cohort study established to evaluate the effectiveness of the campaign to prevent neural tube defects with folic acid supplementation in China. We selected participants who were registered in 2 southern provinces, had exact information on folic acid use, and were not affected by chronic hypertension or diabetes mellitus before 20 weeks gestation. A logistic regression model was used to adjust for the effects of the main potential confounders, including age, body mass index, education, occupation, parity, and multiple births. The study size had 99.9% power (α=0.05) to detect a decrease of 10% over the unexposed rate of 9.4% for gestational ...
INTRODUCTION: In 2012, the Government of Kenya amended the Food, Drug and Chemical Substances Act to mandate the fortification of maize and wheat flour with folic acid. We assessed folate deficiency, awareness, and folic acid use among pregnant women receiving antenatal care (ANC) at a clinic at Pumwani Maternity Hospital, Kenya, 2015. METHODS: we conducted a cross-sectional survey at Pumwani Maternity Hospital between October and November 2014. We enrolled pregnant women who received ANC, and interviewed them using a semi-structured questionnaire after obtaining informed consent. Blood samples were collected from all study participants and serum folate level was analyzed by electrochemiluminescence immunoassay. Folate deficiency was defined as serum folate of < 10nmols/L and borderline folate deficiency was defined as serum folate of between 10nmols/L and 15nmols/L. RESULTS: among the 247 study participants, two (1%) had folate deficiency. One hundred and seventy-nine (73.4%) had heard about folic acid

Neural tube defects (NTDs) result from failure of the neural tube to close during early embryogenesis (between 21 and 27 days of gestation2) and are the most common serious congenital neurologic malformations seen in humans. Of all NTDs, 50% are spina bifida cystica (myelomeningocele, meningocele, encephalocele), and about 40% are anencephalies.2 The causative role of folate deficiency in NTDs has been suspected for more than 25 years.3 Two recent multicentre studies demonstrated this role through prospective, randomized, placebo-controlled trials.3,4 A recent study by Motherisk5 showed that women who gave birth to children with NTDs knew very little about the role of folic acid. Also, it has been shown that more than 25% of pharmacists in the Toronto area are unaware of the importance of periconception folic acid supplementation and, consequently do not recommend or advise folic acid supplementation to their female customers.6 These data suggest that 4 years after the role of folate deficiency ...
Countries across the world insist on the addition of folic acid to various food items. It is because folate supplements, rich in vitamin B, help reduce the number of birth defects and other folate deficiency diseases. Folate supplements can be beneficial in preventing and treating several diseases and illnesses.
In hypertension baroreceptor-mediated modulation of heart rate is impaired, resulting in a decreased vagal control. Reactive oxygen species produced locally in the vasculature decrease baroreceptor sensitivity. Folic acid has antioxidant properties. Therefore, the aim of this study was to test whether folic acid improves baroreceptor function in hypertension. Twenty-one male patients with hypertension not taking any drugs for 2 weeks participated in the study and were randomized to folic acid 5 mg or matching placebo. Cardiac and vascular sympathetic baroreceptor functions were tested before and after a single dose of folic acid or placebo with two different methods: the alpha-coefficient method and the phenylephrine (PE) and sodium nitroprusside (SNP) bolus method. In the folic acid group both methods showed significantly improved cardiac and vascular sympathetic baroreceptor sensitivity compared with placebo. This study provides evidence that folic acid improves cardiac and vascular ...
Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies (NDA) derived Dietary Reference Values (DRVs) for folate. The Panel concludes that an Average Requirement (AR), as well as a Population Reference Intake (PRI) assuming a coefficient of variation (CV) of 15 % to account for the additional variability associated with the higher requirement for folate in individuals with the methylene-tetrahydrofolate reductase (MTHFR) 677TT genotype, can be derived from biomarkers of folate status. Several health outcomes possibly associated with folate intake/status were also considered, but data were found to be insufficient to establish DRVs. For adults, the AR is determined from the folate intake required to maintain folate adequacy characterised by serum and red blood cell folate concentrations of ≥ 10 and 340 nmol/L, respectively. An AR of 250 µg dietary folate equivalents (DFE)/day and a PRI of 330 µg DFE/day are derived. For infants aged 7-11 ...
Neural tube defects (NTD) are among the most common birth defects and the leading cause of infant mortality. NTDs occur when the neural tube fails to close during early fetal development. The two most common types of NTD are spina bifida and anencephaly. NTDs result in lifelong complications like musculoskeletal deformities and loss of strength. The etiology of NTDs is complex and involves still unclear environmental and genetic factors. However, one of the well-established risk factors of NTDs is folic acid deficiency. The prevalence of NTDs can be lowered by an adequate intake of folic acid in the periconceptual period. In 1996, the Food and Drug Administration mandated that 140 micrograms of folic acid be added to 100 grams of bleached grain products with the goal of reducing the prevalence of NTDs. In the years following this fortification mandate, studies have shown that blood folate levels have more than doubled on average, that there are demographic and socioeconomic disparities in blood folate
Folic acid is a B vitamin that allows every cell in your body to grow and develop normally. Folic acid is especially important to women of childbearing age. You can easily find folic acid in your everyday multivitamin pill, and taking it can reduce a babys risk for neural tube defects, a birth defect that leaves the spinal cord exposed, and causing serious medical complications. Folic acid helps to prevent these and other serious birth defects only when taken before pregnancy and in the first few weeks after conception - often before a woman even knows she is pregnant. It is vital that any woman of childbearing age take folic acid, even if she doesnt plan on becoming pregnant.. Learn more about the importance of folic acid from the March of Dimes. ...
KMD BOTANICALS Folic Acid is an organic supplement that contains natural herbs and plants including Spirulina and Alfalfa, which have a natural source of folic acid. Folic Acid also contains B-complex vitamins; this is needed by the body to manufacture red blood cells. A deficiency of this vitamin causes certain types of anemia (low red blood cell count). Pregnant Women and Women of childbearing age should take B vitamin every day as part of a healthy nutrition. This may help reduce the risk of having a child with brain or spinal cord defects. Folic Acid, B12 and B6 provide dietary support for the cardiovascular system.. Folic Acid, also known as B9, is one of 8 B vitamins that help in converting carbohydrates into fuel (glucose). These B vitamins - often referred to as B complex vitamins- also help the body use fats and protein. B complex vitamins are needed for healthy skin, hair, eyes, and liver in addition to helping the nervous system function properly. The Folic acid formula is the natural ...

Vitamin B12Vitamin B12: According to a review, folate supplementation might mask vitamin B12 deficiency (113; 408). In older persons with low vitamin B12 status, high serum folate was associated with anemia and cognitive impairment (409). Some authors suggest adding 1mg cobalamin to folate supplements (141). In American seniors with a serum vitamin B12 concentration ,148pmol/L, the presence of detectable circulating unmetabolized folic acid was related to lower cognitive test scores and lower mean cell volume (410). Vitamin B12 and folate may have increased effects on homocysteine levels over folate alone (411; 412; 413). A combination of B12 and folate had a lack of improvement on cognitive function in older adults (414) or vascular function (415). Post folic acid fortification, the proportion of individuals with low serum vitamin B12 concentrations without macrocytosis is higher in some (416) but not all (417) studies. Vitamin B12 may increase the preventive effects of folate on neural tube ...
For pregnant women who are continuing to take folic acid supplements even after their first trimester is over, here is a word of caution from researchers who studied the relation of folic acid in late pregnancy and the chances of developing asthma in children.. Lead by Dr. Michael Davies, of the University of Adelaide, Australia, researchers conducted a study on 400 children whose mothers had been followed since pregnancy. It was revealed that 12 percent of the children had developed asthma by age 3 and the same percentage showed signs of the respiratory problem by age 5.. What the doctor pointed out though, that this does not contradict with the use of Folic Acid supplement in early pregnancy, specifically during the first trimester.. It is actually very important for expectant mothers to take 400 micrograms of folic acid daily to ensure the fetus does not have any neural tube defects. These birth defects of the spine and the brain include an anomaly called Spina bifida in which the spinal ...
Various hormones have been studied as regards prediction of pregnancy outcome after infertility treatment, but no ideal candidate has been found. Folate and genetic variations in folate metabolism have also been associated with infertility, but it remains unclear how these factors affect IVF pregnancy outcome. It is known that infertility is associated with active folic acid supplement use, but the effect of socioeconomic and lifestyle factors on folic acid supplement use in infertile women has not been well investigated. The overall aim of this work was to obtain information on the prediction of live birth, and to study factors affecting the role of folate and folic acid intake in relation to IVF pregnancy outcome. Infertile women with various infertility diagnoses were studied. Healthy, fertile non-pregnant women were used as controls in three of the studies. Blood samples were taken for assay of eight different hormones, folate and homocysteine, and for genomic DNA extraction. A questionnaire ...
Concerns about risks for older people with vitamin B12 deficiency have delayed the introduction of mandatory folic acid fortification in the UK. We examined the risks of anaemia and cognitive impairment in older people with low B12 and high folate status in the setting of voluntary fortification in the UK. Data were obtained from two cross-sectional studies (n 2403) conducted in Oxford city and Banbury in 1995 and 2003, respectively. Associations (OR and 95 % CI) of cognitive impairment and of anaemia with low B12 status (holotranscobalamin | 45 pmol/l) with or without high folate status (defined either as serum folate |30 nmol/l or |60 nmol/l) were estimated after adjustment for age, sex, smoking and study. Mean serum folate levels increased from 15.8 (sd 14.7) nmol/l in 1995 to 31.1 (sd 26.2) nmol/l in 2003. Serum folate levels were greater than 30 nmol/l in 9 % and greater than 60 nmol/l in 5 %. The association of cognitive impairment with low B12 status was unaffected by high v. low folate status (
The main finding of the current study was the significant lower level of serum folic acid in women with PTB and folic acid level was associated with lower risk of PTB. This goes with the previous studies where Chen et al., have reported that higher plasma folate concentrations were associated with a longer gestational age and associated with lower risk of PTB [9]. Likewise Furness et al., have shown that women who had a lower Red blood cells (RBCs) folate level in early (12-14 weeks) pregnancy were 5.4 times at higher risk to have PTB [11]. In a large clinical trial, it has recently been shown consumption of folic acid/ other micronutrient in the first trimester lead to a 41%-45% risk reduction for PTB [17].. In contrast to our findings, it has recently been reported that supplemental folate intake was not significantly associated with the risk of PTB [12]. Interestingly, women who received folic acid supplementation more than 8 weeks before conception were at increased risk for PTB compared ...

Birth defects are a major cause of infant mortality and disability in many parts of the world. Neural tube defects (NTDs) are one of the most common types of birth defects. In 2001, the Chinese population and family planning commission initiated a national intervention program for the prevention of birth defects. A key step in the program was the introduction of folic acid supplementation. Of interest in the present study was to determine whether folic acid supplementation has the same protective effect on NTDs under various geographical and socioeconomic conditions within the Chinese population and the nature in which the influence of environmental factors varied after folic acid supplementation. In this study, Heshun was selected as the region of interest as a surrogate for helping to answer some of the questions raised in this study on the impact of the intervention program. Spatial filtering in combination with GIS software was used to detect annual potential clusters from 1998 to 2005 in Heshun,

AU - Rijksen, G. AU - Schornagel, J H. PY - 1989/4/15. Y1 - 1989/4/15. N2 - We have isolated variants of L1210 cells (L1210B) expressing, in addition to the classical high affinity/low capacity system for reduced folate uptake, high levels of a membrane-associated folate binding protein. This folate binding protein was expressed in L1210 cells grown at low physiological folate levels (less than 0.5 nM), but down-regulated after transfer in standard high folate (2 microM) medium. The binding capacity of L1210B cells for [3H]folic acid and [3H]-methotrexate was identical (5-11 pmol/10(6) cells) but affinities were different. The affinities relative to folic acid were 0.5 for 5-methyltetrahydrofolate, 0.25 for 5-formyltetrahydrofolate, 0.08 for 10-ethyl-10-deazaaminopterin, and 0.05 for methotrexate, ...
Background: Clinical studies suggest that mild methylenetetrahydrofolate reductase (MTHFR) deficiency and high dietary folate may reduce the risk for colorectal cancer. There is concern, however, that high folate intake (a consequence of food fortification) may enhance tumour growth in individuals with pre-existing tumours or genetic predisposition to tumorigenesis.. Aim: To determine if Mthfr deficiency and low dietary folate influence tumorigenesis in mice genetically predisposed to form numerous intestinal adenomas (Apcmin/+).. Methods: Male Apcmin/+ mice were mated with Mthfr+/− and/or Mthfr+/+ females. Diets with variable folate content were administered either pre-natally or at weaning; tumours were counted in offspring at 10 weeks of age. Plasma homocysteine and levels of apoptosis, DNA methylation and nucleotide ratios (dUTP:dTTP) in normal (pre-neoplastic) intestine were measured.. Results: Apcmin/+ mice fed high folate diets from weaning developed more adenomas than those fed the ...
Low blood folate levels result in hyperhomocysteinemia, which has been associated with increased risk for cardiovascular disease, neural tube defects and cognitive deficits. Intake of dietary folates is the chief determinant of blood folate levels. Molecular defects in the intestinal absorption of dietary folates that precipitate low blood folate levels and hyperhomocysteinemia have not been investigated previously. Dietary folates are a mixture of polyglutamylated folates which are digested to monoglutamyl folates by the action of folylpoly-gamma-glutamate carboxypeptidase (FGCP), an enzyme that is anchored to the intestinal brush border membrane and is expressed by the glutamate carboxypepidase II (GCPII) gene. We cloned GCPII cDNA from human intestine and identified both a full-length transcript and a 93 bp shorter transcript lacking exon 18, consistent with the presence of a splice variant. In addition, we identified an H475Y polymorphism in GCPII in DNA samples from a healthy Caucasian population

The report also said that it is difficult to estimate the impact folic acid fortification have on the prevalence of NTDs in New Zealand because there is no reliable data on the current prevalence of NTD pregnancies.. The general folate status of New Zealand women of child-bearing age is very good. It is the same as, or better than, that of women in the US after the introduction of mandatory fortification,​ Smith and Refsum said.. Based on the best evidence available, we suggest that fortification may prevent no more than 6 NTD pregnancies per year, but quite possibly none, ​they said.. Very few other benefits​. The report also suggested that there are rather few population studies on other possible beneficial effects of folic acid fortification.. The data on other congenital defects is inconsistent and this may in part be due to changes in diagnostic practice over time. Some defects appeared to be more common after fortification, while others may have decreased, ​they said.. The ...
Over three years have passed since an increase in the intake of folic acid among women planning a pregnancy was shown to prevent most neural tube defects.1 The evidence is conclusive; prevention is effective for women who have not had a pregnancy in which the fetus had a neural tube defect as well as for those who have.2 National authorities have recommended that women planning a pregnancy should increase their intake of folic acid.3 4 5 The extra folic acid needed for a reasonable protective effect is 0.4 mg a day, twice the current average dietary intake of 0.2 mg. If no screening was carried out for neural tube defects (with subsequent abortions) about 1500 affected children would be born each year in Britain. Over 1000 of these defects could be prevented by women consuming extra folic acid. Sadly, most people are still not aware of the importance of folic acid in the prevention of neural tube defects.6 7 A public health initiative is urgently needed; the tragedy of a pregnancy in which the ...

Many microorganisms and plants possess the ability to synthesize folic acid derivatives de novo, initially forming dihydrofolate. All the folic acid derivatives that serve as recipients and donors of one-carbon units are derivatives of tetrahydrofolate, which is formed from dihydrofolate by an NADPH-dependent reduction catalyzed by dihydrofolate reductase (FolA). This review discusses the biosynthesis of dihydrofolate monoglutamate, its reduction to tetrahydrofolate monoglutamate, and the addition of glutamyl residues to form folylpolyglutamates. Escherichia coli and Salmonella, like many microorganisms that can synthesize folate de novo, appear to lack the ability to transport folate into the cell and are thus highly susceptible to inhibitors of folate biosynthesis. The review includes a brief discussion of the inhibition of folate biosynthesis by sulfa drugs. The folate biosynthetic pathway can be divided into two sections. First, the aromatic precursor chorismate is converted to paminobenzoic acid
Results A total of 112 children receiving antiepileptic monotherapy for ,6 months were enrolled. Hyperhomocysteinaemia was present in 54 children (90%) receiving phenytoin, 45 children (90%) receiving carbamazepine therapy and 17 (34%) controls (p,0.05). Mean plasma homocysteine concentrations were significantly higher (18.9±10.2 vs 9.1±3 µmol/L) and serum folic acid concentrations (10.04±8.5 ng/ml vs 12.6±4.8 p,0.001) and vitamin B12 concentrations (365±155 pg/mL vs 474±332 pg/mL, p=0.02) were significantly lower in the study group compared with the control group. Duration of antiepileptic drug therapy correlated significantly with elevated homocysteine and reduced folic acid concentrations (p,0.05). Supplementation with folic acid for 1 month led to a reduction in plasma homocysteine concentrations in the study group (from 20.9±10.3 µmol/L to 14.2±8.2 µmol/L, p,0.05). ...
Hispanic women are about 20 percent more likely than other women to have babies with those conditions[neural tube defects], and they continue to have far lower levels of folic acid intake, either through diet or supplements, NBC News shared.. The FDA could approve the use of a food additive only after conducting a scientific safety review of the information provided in the petition to ensure that the additive is safe for the general population. With regard to folic acid, the FDA evaluated the projected human dietary exposure, toxicological data, and other relevant information, including whether folic acid remained stable in corn masa flour.. The FDA worked with the petitioners throughout the review process to obtain data needed to address safety questions as expeditiously as possible. Based on that data, the FDA concluded that the petitioned addition of folic acid to corn masa flour at a level not to exceed 0.7 milligrams of folic acid per pound of corn masa flour is safe.. Exposure estimates ...
Methotrexate is an antineoplastic anti-metabolite. Anti-metabolites masquerade as purine or pyrimidine - which become the building blocks of DNA. They prevent these substances becoming incorporated in to DNA during the S phase (of the cell cycle), stopping normal development and division. Methotrexate inhibits folic acid reductase which is responsible for the conversion of folic acid to tetrahydrofolic acid. At two stages in the biosynthesis of purines and at one stage in the synthesis of pyrimidines, one-carbon transfer reactions occur which require specific coenzymes synthesized in the cell from tetrahydrofolic acid. Tetrahydrofolic acid itself is synthesized in the cell from folic acid with the help of an enzyme, folic acid reductase. Methotrexate looks a lot like folic acid to the enzyme, so it binds to it quite strongly and inhibits the enzyme. Thus, DNA synthesis cannot proceed because the coenzymes needed for one-carbon transfer reactions are not produced from tetrahydrofolic acid ...

Dr. Roy Gravel, also a co-author of the study and member of the Alberta Childrens Hospital Research Institute says this study provides a tremendous opportunity to look at the prevention of diseases like spina bifida. The work began as a study of a gene called Mtrr in mice. The goal was to shed light on how a mutation in Mtrr would affect folate metabolism. The multigeneral effect we observed was completely unexpected, says Gravel. The Mtrr gene encodes an enzyme that is key to the metabolism of folic acid and, when mutated, causes similar effects to dietary folic acid deficiency. The researchers found that when either the maternal grandmother or the maternal grandfather had this Mtrr mutation, their genetically normal grandchildren were at risk of a wide spectrum of developmental abnormalities, even if the mutated gene was not inherited through to the next generations. These developmental abnormalities were also seen in the fourth and fifth generations of mice. Through a series of ...

Neural tube defects (NTDs) are malformations of the cranium, spine, and nervous system; types of NTDs include anencephaly, spina bifida, encephalocele, and meningocele. Neural tube defects are a major cause of mortality in newborns and have been estimated to affect 0.5 to 8 per 1000 live births. Health Canada has estimated that 195 Canadian infants are born each year with NTDs. Overall, NTDs affect approximately 300 000 infants worldwide.. Epidemiological studies that associate folate supplementation with a decreased risk of NTDs date back to the 1960s. The most definitive research addressing the benefits of folic acid supplementation in decreasing the risk of NTDs was the multicentre, randomized, double-blind trial by the Medical Research Council in the United Kingdom. 1 The aim of this trial was to evaluate the efficacy of 4-mg doses of folic acid in preventing recurrent NTDs in women who had previously delivered children with NTDs. The trial showed that women randomized to take folic acid ...
The campaigns story is outlined, from the MRCs groundbreaking results, through the recommendation in favour of flour fotification by the Committee on Medical Aspects of Nutrition (COMA), and the UK-wide health education campaign on folic acid, to the refusal of the Food Standards Agency (FSA) to recommend fortification in 2003, and a possible change of heart in 2006.. The cases for and against fortification are summarised, including the significant fall in NTD pregnancies in nations that have fortified, and the allegation that folic acid might mask anaemia symptoms in older people with vitamin B12 deficiency. Meanwhile, over 1,200 NTD pregnancies are continuing to occur annually in the UK.. ASBAHs activities have included lobbying politicians, enlisting the support of experts and organisations, seeking media publicity, and liaising with key government agencies. ...

Binding of 3H-folate in Triton X-100 solubilized human prostate homogenate was of a high-affinity type and displayed apparent positive cooperativity typical of specific folate binding. Radioligand dissociation was slow at pH 7.4, but rapid at pH 3.5. Gel chromatography reveled two major folate binding proteins (Mr≈100 and 25kDa), but only one single band (Mr ≈ 65-70 kDa) was detectable on SDS-PAGE and immunoblotting with rabbit-anti human milk folate binding protein. Concentration of folate binding protein in prostate homogenate expressed as maximum 3H-folate binding was 1.10 nmol/g protein, and the cross-reactivity with rabbit-anti human milk folate binding protein serum was 15% as determined by an enzyme-linked immunosorbent assay (median values; n = 6).. ...

PY - 1969/1/1. Y1 - 1969/1/1. N2 - Previous work on the diethylaminoethylcellulose chromatography of CH2O derivatives of tetrahydrofolic acid leading to the isolation of diastereoisomers, designated as 5,10-methylene derivatives, was repeated using formaldehyde-14C. The isolated material contained 0.7-0.8 mole of formaldehyde/mole of tetrahydrofolate rather than 1 required for the 5,10-methylene structure. This finding was verified by chemical determination of CH2O on the isolated material. Comparable experiments with CH2O derivatives of tetrahydroaminopterin yielded 0.7 mole of CH2O/mole of tetrahydropteridine. These results suggest that the compounds designated as diastereoisomers of 5,10-methylenetetrahydrofolate are actually complexes which contain 4 molecules of tetrahydropteridine and 3 molecules of ...
Aminopterin (4-Aminofolic acid), the 4-amino derivative of folic acid, is a folic acid antagonist. Aminopterin catalyses the reduction of folic acid to tetrahydrofolic acid, and competitively inhibits dihydrofolate reductase (DHFR) with a Ki of 3.7 pM. Aminopterin has anticancer and immunosuppressive activity. Aminopterin is used in treatment of pediatric leukemia. - Mechanism of Action & Protocol.

Defective closure of the neural tube during embryogenesis results in serious and common birth defects such as spina bifida and anencephaly. Neural tube defects (NTDS) occur at an average rate in the U.S. of 1 per 1000 live-births with selected ethnic groups having higher or lower prevalence rates. Several investigators have shown a marked decrease in the occurrence and recurrence rates of NTDs with the administration of periconceptional supplemental folic acid. Intracellular folates are believed to be responsible for the reduction in NTDs due to their role in facilitating single-carbon transfers in critical biochemical pathways leading to DNA synthesis. Alterations in the folate pathway could compromise DNA synthesis and cellular proliferation, potentially disrupting normal developmental events. To this end, the genetic regulation of folate internalization is being investigated. The reduced folate carrier (RFC) delivers 5-methyltetrahydrofolate from the folate receptors to the cytoplasm of the ...
In response to mounting evidence from observational studies and randomised trials of the benefits of periconceptional folic acid in reducing the risk of neural tube defects, the National Health and Medical Research Council (NHMRC) recommended that women planning a pregnancy or likely to become pregnant should be offered advice about dietary folate and periconceptional folic acid supplementation. Subsequently an NHMRC Expert Panel on Folate Fortification recommended voluntary folate fortification of foods.
Microbial metabolites, including B complex vitamins contribute to diverse aspects of human health. Folate, or vitamin B9, refers to a broad category of biomolecules that include pterin, para-aminobenzoic acid (pABA), and glutamate subunits. Folates are required for DNA synthesis and epigenetic regulation. In addition to dietary nutrients, the gut microbiota has been recognized as a source of B complex vitamins, including folate. This study evaluated the predicted folate synthesis capabilities in the genomes of human commensal microbes identified in the Human Microbiome Project and folate production by representative strains of six human intestinal bacterial phyla. Bacterial folate synthesis genes were ubiquitous across 512 gastrointestinal reference genomes with 13% of the genomes containing all genes required for complete de novo folate synthesis. An additional 39% of the genomes had the genetic capacity to synthesize folates in the presence of pABA, an upstream intermediate that can be obtained

Folate hydrolase 1 (FOLH1) gene encodes intestinal folate hydrolase, which regulates intestinal absorption of dietary folate. Previous studies on the association between polymorphisms rs202676 and rs61886492 and the risk of neural tube defects (NTDs) were inconclusive. A case-control study of women with NTD-affected pregnancies (n = 160) and controls (n = 320) was conducted in the Chinese population of Lvliang, a high-risk area for NTDs. We genotyped the polymorphic sites rs202676 and rs61886492 and assessed maternal plasma folate and total homocysteine (tHcy). Our results showed that in case group, plasma folate concentrations were 18 % lower compared with those of control group (8.32 vs. 6.79 nmol/L, p = 0.033) and tHcy concentrations were 17 % higher (10.47 vs. 12.65 μmol/L, p = 0.047). Almost all samples had the rs61886492 GG genotype (99.78 %). The result showed that the frequency of GG genotype in rs202676 was significantly higher in group with multiple NTDs than in controls (p = 0.030, OR = 2
Our results show that in the UK between 1998 and 2012, there was little, if any, change in the prevalence of pregnancies with an NTD, while in the USA, quickly following the introduction of mandatory fortification of flour with folic acid in 1998, there was an approximate 23% reduction in the occurrence of affected births.2-4 Given the evidence from the MRC Vitamin Study1 regarding the efficacy of folic acid in preventing NTDs, the failure of Britain to fortify flour with folic acid has had significant consequences.. The recent evidence that only 28% of pregnant women in England in 2012 took folic acid supplements at the correct time indicates that, in practice, recommending folic acid supplementation is largely ineffective.19 In addition, a recent report showed that the median level of serum folate in women from the UK aged 16-49 was 7.1 ng/mL in samples obtained from 2008 to 2012.21 This is in comparison with the median levels of 5 ng/mL observed in the samples collected from 1983 to 1991 from ...

These results suggest that folate supplementation might be useful to decrease Al accumulation in its main target organs, i.e., bone, kidney, and brain.
In 2009, Australia implemented mandatory folic acid fortification in wheat flour for bread-making. The primary aim was to improve folate status in reproductive-aged women to reduce neural tube defect incidence. However, folic acid consumption has consequently increased in all demographics. Blood folate is inversely associated with homocysteine levels, a risk factor for multiple diseases. Therefore ...
Periconceptional folic acid use can often prevent neural tube defects (NTDs). Variants of genes involved in folate metabolism in mothers and children have been associated with occurrence of NTDs. We identified Irish families with individuals affected by neural tube defects. In these families, we observed that neural tube defects and birth defects overall occurred at a higher rate in the maternal lineage compared with the paternal lineage. The goal of this study was to look for evidence for genetic effects that could explain the discrepancy in the occurrence of these birth defects in the maternal vs. paternal lineage. We genotyped blood samples from 322 individuals from NTD-affected Irish families, identified through their membership in spina bifida associations. We looked for differences in distribution in maternal vs. paternal lineages of five genetic polymorphisms: the DHFR 19 bp deletion, MTHFD1 1958G>A, MTHFR 1298A>C, MTHFR 677C>T, and SLC19A1 80A>G. In addition to looking at genotypes ...

Aim In order to reduce the risk of neural tube defects (NTDs) and iodine deficiency in pregnancy, the National Health and Medical Research Council recommends that pregnant women supplement their diet with folic acid and iodine. This study aimed to identify the knowledge, attitudes and practices of pregnant women regarding intake of these nutrients in order to assess whether women are adequately exposed to this health message. Methods One hundred and fifty-two conveniently sampled pregnant women residing in a regional area of New South Wales, Australia, completed a pretested questionnaire on knowledge and practices regarding nutritional supplement use during pregnancy and dietary sources of folic acid and iodine. Results Eighty-two per cent of women reported using supplements during their pregnancy, with the majority (67.7%) taking supplement brands containing both folic acid and iodine. Supplement use was significantly higher among women in the highest household income category (30.8 vs 69.2%; P = 0.001
