Foods High In Folate: 9 Best Sources For 2025
Boost your intake of this essential B vitamin with these nutrient-packed foods to support cell growth and prevent deficiency.
Folate, also known as vitamin B9, is a water-soluble B vitamin essential for DNA synthesis, red blood cell formation, and overall cell growth and function. It plays a critical role in preventing neural tube defects during pregnancy and supporting heart health.
What Is Folate?
Folate is the natural form of vitamin B9 found in foods, while folic acid is the synthetic version added to fortified foods and supplements. The body absorbs folic acid more efficiently than natural folate. Since 1998, the U.S. FDA has mandated folic acid fortification in enriched grain products like breads, cereals, and pastas, reducing neural tube birth defects by 28%.
Adults need 400 mcg DFE (dietary folate equivalents) daily, with pregnant individuals requiring 600 mcg DFE. One mcg DFE equals 1 mcg food folate or 0.6 mcg folic acid from fortified foods/supplements.
Why You Need Folate
Folate supports healthy cell division, prevents anemia, and lowers homocysteine levels to protect cardiovascular health. It’s vital in early pregnancy to avoid birth defects like spina bifida. Deficiency risks include poor diet, malabsorption (e.g., celiac disease), or increased needs during pregnancy/lactation.
Signs of deficiency: fatigue, weakness, pale skin, mouth sores, and elevated homocysteine. Toxicity is rare from food but possible from excess supplements (>1,000 mcg/day).
Foods High in Folate
Incorporate these folate-rich foods into your diet. Values are approximate mcg DFE per serving; check labels for fortified items.
1. Leafy Green Vegetables

How to Get Enough Folate
Aim for a varied diet with greens, legumes, and fortified grains. Pregnant people: 400–800 mcg folic acid daily via supplements/foods. Cooking tip: Folate is heat-sensitive; steam or eat raw when possible.
Frequently Asked Questions (FAQs)
What is the difference between folate and folic acid?
Folate is natural in foods; folic acid is synthetic, better absorbed, and used in fortification/supplements.
How much folate do I need daily?
Adults: 400 mcg DFE; pregnant: 600 mcg; lactating: 500 mcg.
Can I get enough folate from food alone?
Yes, with a balanced diet, but fortification helps meet needs. Supplements recommended for pregnancy.
Who is at risk for folate deficiency?
Pregnant women, those with malabsorption (celiac, IBD), poor diets, or alcohol use.
Is too much folate harmful?
Food sources are safe; excess folic acid (>1,000 mcg) may mask B12 deficiency.
