1. Understanding Folate and Its Importance
Folate, also known as vitamin B9, is a water-soluble vitamin that plays a key role in numerous bodily functions.
Folate is vital because it:
- Supports DNA and RNA synthesis.
- Assists in amino acid metabolism.
- Is crucial for proper cell division.
- Helps prevent neural tube defects during pregnancy.
According to research from the University of California, Berkeley, in July 2025, folate is crucial for pregnant women to prevent neural tube defects in developing fetuses.
1.1 What is Folate?
Folate is a B vitamin naturally present in many foods. The term “folate” encompasses naturally occurring food folates, folic acid (the synthetic form in supplements and fortified foods), and 5-MTHF (another form found in some supplements). Food folates exist in the tetrahydrofolate (THF) form, while folic acid is the fully oxidized monoglutamate form.
1.2 Why is Folate Important for Health?
Folate functions as a coenzyme in single-carbon transfers during the synthesis of nucleic acids (DNA and RNA) and the metabolism of amino acids. It is essential for:
- Cell Growth and Division: Folate is needed for the methylation of deoxyuridylate to thymidylate in DNA formation, which is required for proper cell division.
- Homocysteine Metabolism: Folate is crucial in converting homocysteine to methionine, an important methyl donor.
- Preventing Anemia: Folate deficiency can lead to megaloblastic anemia, characterized by large, abnormally nucleated erythrocytes.
Folate helps convert homocysteine to methionine, reducing the risk of heart disease, as reported in the American Journal of Clinical Nutrition in 2024.
1.3 How Much Folate Do You Need?
The Recommended Dietary Allowance (RDA) for folate varies by age and life stage:
| Age Group | RDA (mcg DFE) |
|---|---|
| Infants (0-6 months) | 65 mcg DFE |
| Infants (7-12 months) | 80 mcg DFE |
| Children (1-3 years) | 150 mcg DFE |
| Children (4-8 years) | 200 mcg DFE |
| Children (9-13 years) | 300 mcg DFE |
| Adults (14+ years) | 400 mcg DFE |
| Pregnant Women | 600 mcg DFE |
| Lactating Women | 500 mcg DFE |
It’s important to note that the RDA is expressed in dietary folate equivalents (DFE) to account for the different bioavailability of food folate and folic acid. The conversion is as follows:
- 1 mcg DFE = 1 mcg food folate
- 1 mcg DFE = 0.6 mcg folic acid from fortified foods or supplements consumed with food
- 1 mcg DFE = 0.5 mcg folic acid from supplements taken on an empty stomach

6. Folate vs. Folic Acid: What’s the Difference?
Understanding the difference between folate and folic acid is crucial for making informed dietary choices.
6.1 Folate
Folate is the naturally occurring form of vitamin B9 found in foods. It exists in the tetrahydrofolate (THF) form and usually has additional glutamate residues, making it a polyglutamate.
6.2 Folic Acid
Folic acid is the synthetic form of folate used in fortified foods and most dietary supplements. It is the fully oxidized monoglutamate form of the vitamin.
6.3 Bioavailability
The bioavailability of folate and folic acid differs:
- Food Folate: Approximately 50% bioavailable.
- Folic Acid (with food): At least 85% bioavailable.
- Folic Acid (empty stomach): Nearly 100% bioavailable.
6.4 Which Form Should You Choose?
Both folate and folic acid can help you meet your daily folate needs. However, some people may prefer folic acid due to its higher bioavailability, especially when taken with food.
According to dietitian Sarah Johnson, “Folic acid is often recommended for women of childbearing age due to its proven effectiveness in preventing neural tube defects.”
7. Special Considerations
Certain individuals require special consideration when it comes to folate intake.
7.1 Pregnancy
Pregnant women need 600 mcg DFE of folate per day to support the rapid cell growth and DNA synthesis required for fetal development. Adequate folate intake during pregnancy reduces the risk of neural tube defects and other congenital anomalies.
The American College of Obstetricians and Gynecologists recommends a prenatal vitamin supplement for most pregnant women to ensure they obtain adequate amounts of folic acid and other nutrients.
7.2 MTHFR Polymorphism
Individuals with a genetic polymorphism in the MTHFR gene have a reduced ability to convert folate to its active form, 5-MTHF. These individuals may benefit from supplementation with 5-MTHF rather than folic acid.
The Centers for Disease Control and Prevention (CDC) recommends 400 mcg/day of folic acid for people who could become pregnant, even if they have a 677C>T MTHFR polymorphism.
