Folic acid was added to the diet as a simple means to increase serum folates in gestating sows. At weaning, 95 multiparous sows were randomly assigned to five treatments. Of these sows, 67 farrowed and were used for this trial. Three supplementation levels of folic acid added to a commercial diet at 3, 9 and 27 mg per kg were studied. A commercial diet without any supplementation of folic acid ...

Since the early 1990s, maternal folic acid supplementation has been recommended prior  to and during the first trimester of pregnancy, to reduce the risk of infant neural tube defects. In  addition, many countries have also implemented the folic acid fortification of staple foods, in order  to promote sufficient intakes amongst women of a childbearing age, based on concerns surrounding  variabl...

OBJECTIVE To assess the impact on birth size and risk of low birth weight of alternative combinations of micronutrients given to pregnant women. DESIGN Double blind cluster randomised controlled trial. SETTING Rural community in south eastern Nepal. PARTICIPANTS 4926 pregnant women and 4130 live born infants. INTERVENTIONS 426 communities were randomised to five regimens in which pregna...

BACKGROUND The efficacy of treatments that lower homocysteine concentrations in reducing the risk of cardiovascular disease remains controversial. Our aim was to do a meta-analysis of relevant randomised trials to assess the efficacy of folic acid supplementation in the prevention of stroke. METHODS We collected data from eight randomised trials of folic acid that had stroke reported as one o...

BACKGROUND To study the knowledge of a large city population on preconception folic acid supplementation and intention to seek for preconception care within an urban perinatal health program. METHODS Cross-sectional surveys run in Rotterdam, the Netherlands, in 2007 and annually from 2009 to 2014. A random sample of residents aged between 16 and 85 years was taken each year from the municipal...

BACKGROUND Open neural tube defects are among the most common severely disabling birth defects. Secondary prevention by early diagnosis during pregnancy and abortion of affected fetuses lead to a marked reduction of NTD incidence at birth. For primary prevention of these defects, in August 2000 the Israel Ministry of Health issued guidelines recommending a daily 0.4 mg folic acid supplement for...

Folate deficiency and hyperhomocysteinemia are found in most patients with alcoholic liver disease. Oxidative stress is one of the most important mechanisms contributing to homocysteine (Hcy)-induced tissue injury. However it has not been examined whether exogenous administration of folic acid attenuates oxidative stress and hepatic toxicity. The aim of this study was to investigate the in vivo...

INTRODUCTION folic acid is a water soluble vitamin, which is synthetically-produced and found in fortified foods and supplements. Folate is found naturally in plants, such as the dark green leafy vegetables. Folate is not synthesized de novo by humans, therefore the daily requirements are met from the dietary intake of folic acid supplements or food rich in this vitamin. Folate deficiency could...

Hyperhomocysteinemia is seen in patients with decreased bone mineral density. Cyclosporine can cause alveolar bone loss and osteopenia. It is also associated with elevated serum homocysteine levels. We aimed to investigate the effect of cyclosporine on serum homocysteine level, bone volume, and bone density, and determine whether folic acid had a protective effect against bone loss. In an exper...

OBJECTIVE To determine if folic acid supplementation improves vascular function (brachial artery flow-mediated dilation [FMD]) in professional dancers with known endothelial dysfunction. DESIGN Prospective cross-sectional study. SETTING Academic institution in the Midwestern United States. SUBJECTS Twenty-two professional ballet dancers volunteered for this study. MAIN OUTCOME MEASURES ...
