When it comes to pregnancy and fetal development, folate and folic acid are two of the most important nutrients for preventing serious birth defects. Understanding their role and ensuring adequate intake before and during pregnancy can dramatically reduce the risk of neural tube defects and promote healthy growth for your baby.
This article explains the difference between folate and folic acid, their critical role during pregnancy, and practical ways to incorporate them into your diet.

What Are Folate and Folic Acid?
- Folate is a naturally occurring B-vitamin (B9) found in various foods such as leafy green vegetables, legumes, nuts, and fruits.
- Folic acid is the synthetic form of folate used in dietary supplements and fortified foods.
Both forms are converted in the body into an active form that supports vital biological functions, especially DNA synthesis and cell division.
Why Folate/Folic Acid is Crucial During Pregnancy
Folate plays a fundamental role in the early stages of pregnancy, especially in the formation of the neural tube, which later develops into the brain and spinal cord. Proper folate levels:
- Prevent Neural Tube Defects (NTDs): Conditions such as spina bifida and anencephaly arise when the neural tube fails to close properly in the first 28 days after conception, often before many women know they’re pregnant.
- Support DNA and RNA synthesis: Essential for the rapid cell growth and division in the developing fetus.
- Promote healthy placental development: Aids in the formation of the placenta, which nourishes the fetus.
- Reduce risk of other birth defects: Some studies suggest folate also lowers risk of cleft lip and palate and heart defects.
Recommended Intake of Folate and Folic Acid
- Women planning to conceive or in early pregnancy: 400 to 800 micrograms (mcg) of folic acid daily is recommended to reduce the risk of NTDs.
- During pregnancy: The recommended daily intake increases to about 600 mcg.
- Women with previous pregnancies affected by NTDs: Higher doses (up to 4,000 mcg) may be advised under medical supervision.
When to Start Taking Folate/Folic Acid
Because neural tube development occurs within the first month after conception, it’s critical to start folic acid supplementation at least one month before pregnancy and continue through the first trimester.
Since many pregnancies are unplanned, all women of childbearing age are encouraged to maintain adequate folate levels through diet or supplements.
Dietary Sources of Folate
In addition to supplements, consuming folate-rich foods can help maintain sufficient levels:
- Leafy green vegetables (spinach, kale, romaine lettuce)
- Legumes (lentils, chickpeas, black beans)
- Citrus fruits (oranges, lemons)
- Avocado
- Broccoli and Brussels sprouts
- Fortified cereals, breads, and pastas
- Nuts and seeds
Folic Acid Supplementation
Prenatal vitamins typically contain folic acid to help meet daily requirements. Supplementation is especially important because:
- Dietary folate is sometimes insufficient, especially if food intake is limited.
- Folate from food is less stable and can be lost during cooking.
- Supplements provide a reliable, measurable dose.
Risks of Folate Deficiency
Folate deficiency during pregnancy can lead to:
- Increased risk of neural tube defects in the fetus
- Elevated homocysteine levels, linked to miscarriage and pregnancy complications
- Maternal anemia and fatigue
Can You Get Too Much Folate?
Excessive intake of folic acid from supplements above 1,000 mcg daily can mask vitamin B12 deficiency and may have other unknown risks. It’s important to follow recommended dosages and consult a healthcare provider before taking high doses.
Conclusion
Folate and folic acid are indispensable nutrients in the prevention of serious birth defects and the support of healthy fetal development. Starting supplementation before conception and continuing through early pregnancy, combined with a folate-rich diet, gives your baby the best chance for a healthy start.
If you’re planning a pregnancy or are pregnant, talk to your healthcare provider about the right folic acid supplement and dietary plan tailored to your needs. With the right folate intake, you’re taking a crucial step in protecting your baby’s future health.
