What is folic acid?

Folic acid, also known as folate or vitamin B9, is a water-soluble vitamin that is essential for various bodily functions. It plays a crucial role in the production and maintenance of new cells, including the synthesis of DNA, RNA, and proteins.

Folic acid is particularly important during periods of rapid growth and development, such as pregnancy and infancy. It helps in the formation of the neural tube in the developing fetus, which eventually becomes the baby’s brain and spinal cord. Adequate intake of folic acid by pregnant women can help prevent certain birth defects, such as spina bifida.

In addition to its role in cell division and growth, folic acid is also involved in the production of red blood cells and in the metabolism of amino acids. It helps convert homocysteine, an amino acid, into methionine, which is essential for normal growth and development.

Folic acid can be obtained from various food sources, including leafy green vegetables, fruits, legumes, fortified cereals, and animal products. However, sometimes dietary intake may not be sufficient, especially during pregnancy or for individuals with certain medical conditions. In such cases, folic acid supplements may be recommended by healthcare professionals.

What is the difference between folic acid and folate?

Folic acid and folate are forms of vitamin B9 and are often used interchangeably. However, there are some differences between the two.

Folic acid is the synthetic form of vitamin B9 that is commonly found in fortified foods and dietary supplements. It is more stable and bioavailable, meaning it is easily absorbed and utilized by the body. Folic acid is converted into its active form, methyltetrahydrofolate (MTHF), in the liver and other tissues.

Folate, on the other hand, refers to the naturally occurring form of vitamin B9 that is found in foods such as leafy green vegetables, legumes, and liver. Folate is already in its active form, so it does not need to be converted by the body.

FDA approval of folic acid

Folic acid is not a specific medication or product name. It is a naturally occurring vitamin that is generally recognized as safe for consumption.

Active ingredient of folic acid

The active ingredient of folic acid is naturally occurring folic acid, which is a form of vitamin B9.

US brand name of folic acid and manufacturer

As folic acid is a naturally occurring vitamin, there is no specific brand name associated with it. Various manufacturers produce folic acid supplements, which are available under different brand names.

UK brand name of folic acid and manufacturer

Similarly, in the UK, there is no specific brand name associated with folic acid as it is a naturally occurring vitamin. Folic acid supplements may be available under different brand names from various manufacturers.

Prescription requirement for folic acid

Folic acid is widely available as an over-the-counter supplement and does not typically require a prescription. However, higher dosage forms of folic acid may require a prescription in certain cases, such as in the treatment of certain medical conditions.

Availability of folic acid in the UK with NHS prescription

Folic acid supplements are available without a prescription in the UK and can be obtained from pharmacies, supermarkets, and other retail outlets.

Uses of folic acid

Folic acid is primarily used for the treatment and prevention of folic acid deficiency (folate deficiency), which can occur due to poor dietary intake, certain medical conditions, or pregnancy. Adequate folic acid levels are crucial for healthy cell division, DNA synthesis, and red blood cell production.

How does folic acid work?

Folic acid is essential for various metabolic processes in the body, including the synthesis of DNA, RNA, and certain amino acids. It plays a critical role in cell division, growth, and the formation of red blood cells:

  • Folic acid is essential for the production and maturation of red blood cells. It helps in preventing certain types of anemia, such as megaloblastic anemia, by aiding the synthesis of DNA and RNA
  • Folic acid is crucial during pregnancy for the prevention of neural tube defects (NTDs) in newborns. Regular consumption of folic acid before conception and during early pregnancy can help prevent conditions like spina bifida and anencephaly, which affect the baby’s brain and spinal cord
  • Folic acid helps lower homocysteine levels, an amino acid that, when elevated, can increase the risk of heart disease and stroke. By reducing homocysteine, folic acid supports cardiovascular health and protects against the development of various heart-related conditions

Forms of folic acid available

There are dietary sources rich in folic acid:
Whole oranges, orange juice, grapefruits, lemons, and other citrus fruits are not only high in vitamin C but also provide a good amount of folic acid. Enjoying these fruits as part of a balanced diet can help increase your folic acid intake. Many grain products, such as bread, pasta, and breakfast cereals, are fortified with folic acid. Leafy vegetables such as spinach, kale, collard greens, and other dark leafy greens are excellent sources of folic acid. These vegetables are not only high in this nutrient but also provide a wide range of vitamins and minerals.If you don’t get enough folic acid from the foods you eat, you can also take it as a dietary supplement. Folic acid is available in various forms, including folic acid supplements and multi-vitamin supplements containing folic acid.

Dosage of folic acid

The recommended daily dosage of folic acid varies depending on age, sex, and life stage. In general, for adults, the recommended daily amount of folic acid is 400 to 800 micrograms (mcg). However, certain individuals may have specific needs:

  • Pregnant women: It is recommended for pregnant women to take 600-800 mcg of folic acid daily to support the healthy development of the fetus
  • Breastfeeding women: Breastfeeding women are advised to take 500 mcg of folic acid daily to ensure sufficient levels for both mother and baby
  • Adults with certain medical conditions: Individuals with certain medical conditions, such as anemia or malabsorption issues, may require higher doses of folic acid as advised by their healthcare professional

If you have any specific concerns or questions about your folic acid intake, it is always best to consult with a healthcare professional for medical advice.

Directions for folic acid use

Folic acid supplements should be taken as directed by the healthcare provider or as indicated on the product packaging. It is typically taken orally with or without food. It is important to follow the instructions provided and not exceed the recommended dosage unless advised by a healthcare professional.

Warnings and precautions

  • Some individuals may be allergic to folic acid. Allergic reactions can manifest as skin rashes, itching, swelling of the face, tongue, or throat, and difficulty breathing. If you experience any of these symptoms after taking folic acid, it is important to seek medical help immediately
  • Folic acid supplements can sometimes cause gastrointestinal problems such as nausea, bloating, gas, and even diarrhea. If you experience persistent digestive issues after taking folic acid, it is advisable to consult your healthcare provider
  • Folic acid can interact with certain medications, including antiepileptic drugs, methotrexate (a medication used for cancer and autoimmune diseases), and some antibiotics. These interactions can reduce the effectiveness of these medications or cause other adverse effects. Therefore, it is crucial to inform your healthcare provider about all the medications you are taking before starting folic acid supplementation
  • Folic acid can mask the symptoms of vitamin B12 deficiency, which is more common in older adults. Vitamin B12 deficiency can lead to neurological problems, so it is important to be aware of this potential interaction. If you are taking folic acid and experience any neurological symptoms such as numbness or tingling in the hands or feet, difficulty walking, memory problems, or confusion, it is important to consult with your healthcare provider to determine if further testing for vitamin B12 deficiency is needed

Drug interactions 

Folic acid supplements generally have a low risk of interactions with other drugs. However, certain medications, such as antiepileptic drugs and methotrexate, may interact with folic acid. It is important to inform the healthcare provider about all medications and supplements you are taking to minimize the risk of interactions.

Side effects of folic acid

Folic acid is generally considered safe when taken as directed. However, high doses of folic acid may cause certain side effects, including:

  • Nausea
  • Bloating
  • Gas
  • Bitter taste in the mouth
  • Sleep disturbances

If you experience any persistent or severe side effects, it is important to seek medical attention.
