Learn why folic acid is essential for your health during pregnancy. Discover top folic acid foods, benefits and how to meet daily needs.
Folic acid is an essential B vitamin that plays a critical role in everything from red blood cell production to healthy pregnancies, and it’s one of the most impactful public health nutrition strategies in the U.S.
Yet despite its importance, many Americans still don’t fully understand what folic acid is, why it matters, or how to get enough of it.
What Is Folic Acid?
Folic acid is the synthetic (man-made) form of folate, also known as vitamin B9.
- Folate occurs naturally in foods like leafy greens and beans
- Folic acid is added to supplements and fortified foods like bread and cereal
Both forms help your body:
- Aid proper brain and spinal cord development in early pregnancy
- Produce healthy red blood cells
- Support DNA production and cell growth
Why Is Folic Acid Important?
1. Supports Healthy Pregnancy and Prevents Birth Defects
Folic acid is best known for its role in preventing neural tube defects (NTDs), serious birth defects of the brain and spine, including spina bifida and anencephaly. These develop within the first few weeks of pregnancy, often before someone even knows they’re pregnant.
That’s why the Centers for Disease Control & Prevention (CDC) recommends that all women of childbearing age get enough folic acid daily — not just those actively trying to conceive. If all women met the recommended intake, up to 70% of neural tube defects could be prevented.
2. A Proven Public Health Success
Since the U.S. required folic acid fortification of enriched grain foods in 1998, neural tube defects have decreased by about 35%, equating to roughly 1,300 fewer cases each year. The CDC even named folic acid fortification one of the top public health achievements of the early 21st century.
Not bad for something as simple as enriched flour.
3. Helps Prevent Anemia and Supports Cell Growth
Folic acid plays a key role in producing red blood cells, which carry oxygen throughout the body. Without enough, you may develop folate deficiency anemia, leading to fatigue, weakness and difficulty concentrating
It also supports rapid cell growth, making it essential during periods like pregnancy, adolescence and overall tissue repair.
4. Many People, Especially Women, Don’t Get Enough
Despite widespread fortification, gaps still exist. The National Institutes of Health (NIH) reported that 17–19% of women under 30 don’t meet folate requirements and about 23% of non-Hispanic Black women have inadequate intake.
Add in the fact that over half of U.S. pregnancies are unplanned, and the need for consistent folic acid intake becomes even more critical.
Top Folic Acid Foods: How to Get Enough
The CDC recommends that all women get 400 micrograms (mcg) of folic acid each day. This can be achieved through fortified foods, natural sources or supplements.
Since 1998, the Food and Drug Administration (FDA) has required food manufacturers enrich and fortify flour with higher levels of folic acid than were originally present in an initiative to help combat nutrient deficiencies in the population. Folic acid is ideal for food fortification (adding nutrients to food) because it is more stable than natural forms of folate.
Best Sources of Folic Acid:
- Ready-to-eat cereals
- Enriched bread, pasta and rice
- Enriched flour and cornmeal products
- Leafy greens (spinach, romaine)
- Beans and lentils
- Citrus fruits
- Avocados
Folic acid is essential for cell growth, red blood cell production and healthy pregnancies. Thanks to enriched grain foods, many Americans are getting more than ever. If you want a simple, effective way to support your health, keep enriched grains in your diet, balance them with whole foods and aim for consistency over perfection.
Because when it comes to nutrients like folic acid, small daily choices add up in a big way.
