Folic acid, vitamin B9 can be found both in food sources and as dietary supplements.

Folate deficiency during gestation can result in neural tube defects like spina bifida. Furthermore, anemia increases due to insufficient red blood cells carrying oxygen to body tissues.

What is Folate?

Folate is a B vitamin found naturally in leafy green vegetables and fruit, as well as in processed food with added folic acid. Your body can also produce its own folate through other sources like choline and the amino acid tetrahydrofolate (THF).

Folate is essential in producing DNA and maintaining health; when consumed through diet or supplements in adequate amounts, your blood levels increase, helping your cells make DNA more efficiently. But too little folate can be harmful – megaloblastic anemia being one such problem which manifests with fatigue, difficulty concentrating, irritability and open sores in the mouth or tongue. Folate deficiency often occurs among those who don’t eat enough folate-rich foods or who don’t absorb it as effectively due to malabsorption syndromes).

Folic acid and other B vitamins help lower homocysteine levels, which have been linked to an increased risk of cardiovascular disease. Folic acid in particular is especially crucial during pregnancy as it reduces risks such as spina bifida and anencephaly in babies born through neural tube birth defects.

How is Folate Synthesized?

Folates are a group of compounds which supply one-carbon units to reactions involved in nucleic acid synthesis and amino acid metabolism, as well as acting as donors (together with B9 and B12 vitamins they form the “methyl group donors”). Animals must obtain folate through diet; however bacteria, yeast and fungi produce some forms of it directly.

Folic acid is the most biologically active form of vitamin B9. It can be found naturally in many foods, including dark leafy greens like broccoli, brussels sprouts and spinach as well as fruits, legumes pulses eggs meat dairy products seafood flour (1). Furthermore, certain grain products such as bread pasta rice ready-to-eat cereals must contain fortified with folic acid to lower risk of neural tube defects in infants (2).

Folate deficiency interferes with DNA synthesis, cell growth and proliferation, amino acid metabolism and is particularly vital during periods of rapid cell division such as infancy and pregnancy (3). Severe folate deficiency symptoms include megaloblastic anemia, macrocytic anemia, polyneuropathy diarrhoea as well as elevated homocysteine levels (5).

What is the Role of Folate in the Body?

Folate is an essential nutrient with several essential functions. It plays an essential part in cell division and tissue growth, brain development and spinal cord health, red blood cell production with vitamin B12 production as well as helping form red blood cells for anemia prevention. A deficiency can result in anemia which leaves your body without enough healthy red blood cells to carry oxygen throughout.

Folic acid can be found naturally in many foods, particularly dark green vegetables like broccoli and brussels sprouts, fruits like avocado, legumes such as beans and peas, and eggs. Supplements or fortified food items containing it such as flour, bread, ready-to-eat cereals, rice pasta or some meat products also contain it.

Studies have linked elevated homocysteine levels with an increased risk for heart disease and stroke; however, no clinical trials have demonstrated that taking folate-based supplements reduces heart disease risk.

What is the Role of Folate in Pregnancy?

Folate is one of the B vitamins essential for proper cell growth. It can be found naturally in foods like leafy green vegetables, fruits and juices, beans and peas as well as fortified breads and cereals; additionally it is included as an integral component in most prenatal vitamins manufactured synthetically as folic acid.

Folic acid intake before and during gestation can significantly lower the risk of serious birth defects, particularly to the brain and spine (neural tube defects). Folic acid can also help prevent spina bifida, in which spinal cord does not form properly, by supporting proper development of its spinal cord.

All women of childbearing age should consume at least 400 micrograms of folic acid daily from diet supplements or fortified foods in addition to getting folate from a balanced diet, but some women may require higher dosages under medical supervision. Folate deficiency is rare but can result in megaloblastic anemia – anemia in which red blood cells do not form correctly – leading to fatigue, weakness, difficulty concentrating and irritability symptoms.

What is the Role of Folate in the Postpartum Period?

Folate (also known as vitamin B9) is essential to cell health and development, playing an essential role in producing red blood cells, DNA and RNA as well as helping prevent birth defects like spina bifida in pregnancy. Furthermore, folate plays an integral part in cell metabolism and producing amino acids for protein synthesis.

Folate can be found in dark green leafy vegetables, beans, peas and nuts; it is also included in multivitamins and prenatal vitamins as folic acid; an alternative synthetic form called 5-methylfolate (5-MTHF) can also be taken orally as dietary supplement; for those with MTHFR C677T gene variant who have difficulty processing folic acid this form may be better absorbed than its traditional equivalent.

The Recommended Dietary Allowance (RDA) of folate/FA is 400 micrograms a day for non-pregnant adults and 600 mcg daily during gestation. Unfortunately, many pregnant women cannot consume enough folate/FA from diet alone and therefore the American College of Obstetricians and Gynecologists advises them to take prenatal vitamins with folic acid in order to decrease the risk of neural tube defects.

What is the Role of Folate in the Elderly?

Folate is known to contribute to DNA formation, and may also help suppress certain forms of cancer; however, studies relating to its relationship to carcinogenesis have yielded mixed results.

Folate deficiency has been linked with elevated concentrations of the amino acid homocysteine in blood, which has been associated with an increased risk of cardiovascular disease and stroke. While some observational studies show a correlation between higher intakes of folate-rich diets or multivitamin supplements and decreased cardiovascular disease risk, however randomized trials need to take place first to prove if lowering homocysteine with folate and other B vitamins reduces this risk.

Elderly adults are at greater risk for folate deficiency due to poor dietary practices and physiological changes that reduce food absorption. It is recommended that elderly individuals consume 400 micrograms of folate daily through foods like dark leafy greens, liver, beef, oranges or fortified cereals or supplements; but before making any decisions based on supplements alone without consulting with their healthcare provider first is also advised. Folate supplements can also be taken directly, however before doing so it is advised to first speak to your healthcare provider or health provider first if taking medications that interact with folate such as anticoagulants which interfere with its absorption.

What is the Role of Folate in the Workplace?

Folate, commonly referred to as vitamin B9, plays an essential role in DNA synthesis and amino acid metabolism. Coenzyme Q10 serves as a cosubstrate in several single-carbon transfer reactions, such as the conversion of homocysteine to methionine and formation of deoxyuridylate-thymidylate ester bonds – key processes for DNA replication and cell division. Folate is essential in producing red blood cells and works in harmony with vitamin B12. Without it, megaloblastic anemia could occur, where too few healthy red blood cells are produced to deliver oxygen around the body. Folate is found naturally in food and supplements under the name of folic acid. To decrease congenital disability risks associated with low folate intakes during gestation and breastfeeding, the Food and Drug Administration requires that folic acid be added to enriched grain products during production to meet this FDA mandate.

What is the Role of Folate in the Diet?

Folate is an essential B vitamin that promotes cell growth, DNA synthesis and heart health risk management by helping metabolize homocysteine. Research suggests that getting enough folate may even help prevent Alzheimer’s.

Food sources of folate include leafy green vegetables (especially dark greens), fruits, berries, citrus fruits, legumes and peas; nuts; eggs; meat; fish; dairy products and fat-free/low-fat grains. Since 1998, the FDA has required that synthetic forms of folate such as folic acid be added to many grain products for pregnant women to help lower their risk for neural tube defects during gestation.

Folate requirements increase dramatically during gestation and breastfeeding, so it is essential that we obtain sufficient folate either through our diets or supplements. A lack of folate can lead to megaloblastic anemia – a condition characterized by fatigue, difficulty concentrating, irritability, changes in skin coloration, hair and fingernail color as well as changes in hair and nail growth – leading to changes in color of skin, hair and fingernails as well as higher risks of fetal abnormalities and low birth weight infants (3).
