Folate / Folic Acid – Benefits and Information
Folate, often mistakenly referred to as folic acid, is a collective term for a group of water-soluble vitamins that occur in various forms. Chemically, folate consists of pteridine derivatives containing p-aminobenzoic acid and different residues of the amino acid glutamate. The name "folate" is derived from the Latin word "folium" for "leaf," as folates are found primarily in green leafy vegetables.
Health Benefits of Folate
Folate contributes to numerous important bodily functions:
- Growth of maternal tissue during pregnancy: Folate is essential for cell division and the growth of maternal tissue. This is especially important for fetal development and the health of the expectant mother.
- Normal amino acid synthesis: Folate plays a key role in the synthesis of amino acids, the building blocks of proteins, thereby supporting the body in building and maintaining tissue.
- Normal blood formation: Folate supports the production of red blood cells and helps prevent anemia. Adequate folate intake is therefore important for healthy blood formation.
- Homocysteine metabolism: Folate regulates homocysteine levels, a metabolic product of protein breakdown that can damage cell structures. Lowering homocysteine contributes to heart health.
- Mental function: Folate is important for the normal function of the nervous system and can help maintain mental health by reducing tiredness and fatigue.
- Immune system function: Folate supports the immune system and helps protect the body against disease.
- Cell division: Folate is essential for DNA synthesis and cell division, which are important for tissue growth and repair.
A folate source should contain at least 15% of the recommended daily intake of 200 µg folic acid.
Sources of Folate
The best natural sources of folate include:
- Green leafy vegetables (e.g., spinach, kale)
- Legumes (e.g., lentils, chickpeas)
- Oranges and orange juice
- Whole grain products
- Avocados
- Eggs
Regular consumption of these foods can ensure adequate folate intake.
Scientific Support
Studies have shown that folate plays a crucial role in supporting cell division, blood formation, and mental health. For more information and scientific evidence, see the National Institutes of Health (NIH) and the European Food Safety Authority (EFSA).
Additional Information about Folate
Folate is the natural form of the vitamin found in foods, while folic acid is the synthetic form commonly used in supplements and fortified foods. Biomedically relevant folates include:
- Folates: The naturally occurring forms of folate in foods, which differ in the residues bound to the nitrogen atoms 5 and 10.
- Folic acid: A synthetic, very stable compound that is quickly and almost completely absorbed by the intestinal wall.
- Tetrahydrofolic acid (THF): The biologically active form of folate that acts as a coenzyme and transfers one-carbon groups.
Folic acid is involved in more than 20 metabolic reactions, mainly in the metabolism of amino and nucleic acids. It is essential for normal amino acid synthesis and cell division and helps regulate homocysteine levels. Folate is also very sensitive to heat and oxygen, which can lead to losses during storage and preparation.
Good to know!
The availability of different forms of folate varies. Synthetic folic acid is almost completely absorbed, while the folates found in foods, often as polyglutamates, are only partially bioavailable. The conversion for folate equivalents is as follows:
- 1 µg folate equivalent (FE) = 1 µg dietary folate = 0.5 µg synthetic folic acid.
- 1 µg FE = 0.5 µg synthetic folic acid (taken on an empty stomach) = 0.6 µg synthetic folic acid (taken with a meal).
Conclusion
Folate is an indispensable vitamin for overall health and particularly important during pregnancy. By consuming at least 15% of the recommended 200 µg folic acid daily, you can support your cell division, blood formation, and mental health.
