What Is Folate?
Folate is a B vitamin that helps the body make DNA and other genetic material and supports normal cell division.
It is naturally found in many foods, particularly leafy green vegetables, beans, peas, and some fruits.
Folate is especially important during periods of rapid cell growth, including pregnancy.
The term folate generally refers to the forms of vitamin B9 that naturally occur in food, while folic acid is a form commonly used in fortified foods and dietary supplements.
Understanding the difference can make nutrition labels and food choices easier to interpret.
Why Does the Body Need Folate?
Folate contributes to several normal functions.
It is involved in:
- DNA production
- Normal cell division
- Red blood cell formation
- Amino acid metabolism
- Normal tissue growth
Because cells constantly need to divide and renew themselves, folate is required throughout life.
Is Folate the Same as Folic Acid?
They are related but not exactly the same.
Folate refers broadly to naturally occurring forms of vitamin B9 found in foods.
Folic acid is a form of vitamin B9 used in:
- Dietary supplements
- Fortified foods
- Some enriched grain products
Both contribute to the body’s folate status, but they are chemically different forms.
Which Foods Contain Folate?
Folate can be found in many foods.
Good sources include:
- Spinach
- Broccoli
- Asparagus
- Beans
- Lentils
- Chickpeas
- Avocado
- Oranges
- Peas
- Peanuts
- Liver
Fortified grain products can also provide folic acid.
Folate in Leafy Green Vegetables
Leafy green vegetables are well-known sources of naturally occurring folate.
Examples include:
- Spinach
- Romaine lettuce
- Kale
- Collard greens
- Other dark green vegetables
Including different vegetables in the diet can therefore help provide folate along with fiber, vitamin C, vitamin K, and other nutrients.
Folate in Beans and Lentils
Legumes can provide meaningful amounts of folate.
Examples include:
- Lentils
- Chickpeas
- Black beans
- Kidney beans
- Other beans
This is another reason legumes can be useful foods: they can provide protein and fiber while also contributing micronutrients such as folate.

Folate in Fruits
Some fruits provide folate.
Examples include:
- Oranges
- Avocado
- Papaya
- Bananas
- Certain other fruits
Fruits also provide other nutrients and plant compounds, making variety more useful than relying on a single fruit.
Folate in Fortified Foods
Some foods have folic acid added during processing.
Fortified foods can include certain:
- Breakfast cereals
- Breads
- Flours
- Pasta
- Grain products
Fortification policies differ between countries.
The nutrition label is therefore the best way to determine whether a particular product contains added folic acid.
Folate and Pregnancy
Folate is particularly important during pregnancy because it is involved in rapid cell division and development.
Adequate folate intake before and during early pregnancy is important for reducing the risk of certain neural tube defects.
Because pregnancy nutrition is an important medical topic, people who are pregnant or planning pregnancy should follow guidance from a qualified healthcare professional regarding folic acid supplementation and dietary intake.
Why Is Folate Important Before Pregnancy?
The neural tube develops very early in pregnancy, sometimes before a person knows they are pregnant.
This is one reason health authorities commonly recommend that people who could become pregnant obtain adequate folic acid.
The specific supplementation recommendation can vary by country and individual circumstances.
For personalized advice, professional guidance is appropriate.
Folate and Red Blood Cells
Folate contributes to normal red blood cell formation.
Insufficient folate can contribute to a type of anemia called megaloblastic anemia.
However, anemia has many possible causes.
For example:
- Iron deficiency
- Vitamin B12 deficiency
- Folate deficiency
can all affect blood-related functions in different ways.
Therefore, anemia should not automatically be attributed to one nutrient.
Folate and Vitamin B12
Folate and vitamin B12 are different B vitamins, but they are closely connected in several metabolic processes.
Both are involved in normal cell function and blood formation.
This is why folate and B12 are often discussed together.
However, they are not interchangeable.
A deficiency in one cannot simply be assumed to be solved by consuming more of the other.
Folate and DNA Production
Every cell needs genetic material to function and reproduce.
Folate participates in processes involved in producing DNA and other genetic material.
This is particularly important during periods of rapid cell division.
It helps explain why folate is important throughout life, even though pregnancy receives particular attention.
How Much Folate Do People Need?
Folate requirements vary according to:
- Age
- Sex
- Life stage
- Pregnancy
- Breastfeeding
Different authorities may express recommendations differently, including in micrograms of dietary folate equivalents.
Rather than treating one number as a universal target, it is useful to understand the major dietary sources and how folate needs change across life stages.
What Happens If You Don’t Get Enough Folate?
Inadequate folate can affect normal cell division and red blood cell formation.
Prolonged inadequate intake may contribute to megaloblastic anemia.
During pregnancy, inadequate folate is associated with an increased risk of neural tube defects.
However, symptoms such as tiredness are not specific to folate deficiency.
A suspected deficiency should be evaluated appropriately rather than diagnosed from symptoms alone.
Can You Get Too Much Folate?
Food naturally provides folate in amounts that are generally part of normal diets.
The situation is different with concentrated supplements and fortified foods containing folic acid.
Very high intake of folic acid can be problematic, particularly because it can complicate the recognition of vitamin B12 deficiency.
This is another example of why taking very large amounts of a nutrient is not automatically better.
Folate From Food vs. Supplements
Folate can come from:
Natural food sources
- Leafy green vegetables
- Beans
- Lentils
- Fruits
- Peanuts
- Liver
Fortified foods
- Certain cereals
- Breads
- Grain products
Supplements
- Folic acid supplements
- Multivitamins
The appropriate source depends on the person’s dietary pattern and individual circumstances.
How Can You Include More Folate in Your Diet?
Practical options include:
- Add leafy greens to meals.
- Include beans or lentils.
- Eat a variety of fruits.
- Include avocado.
- Choose fortified grain products when appropriate.
- Add peas or broccoli to meals.
- Include peanuts or other suitable foods.
Variety is more useful than relying on one “folate superfood.”
A Simple Folate-Rich Meal
Consider a meal containing:
- Lentils
- Spinach
- Avocado
- Brown rice
- Orange slices
This meal provides a combination of:
- Folate
- Fiber
- Plant protein
- Vitamin C
- Carbohydrates
- Other vitamins and minerals
It also demonstrates how different foods can complement one another nutritionally.
Is Folate Found in Meat?
Some animal foods contain folate, but plant foods are important dietary sources.
Liver is particularly rich in folate.
However, liver also contains very high amounts of preformed vitamin A, so it should not simply be eaten in large quantities to obtain folate.
This is a useful example of why individual nutrients should be considered within the whole food.
Is Folate Found in Whole Grains?
Some whole-grain foods can contribute folate, but the amount varies by food.
Fortified or enriched grain products may contain added folic acid.
Therefore, “whole grain” and “fortified with folic acid” are not the same thing.
A product can be one, both, or neither.
Checking the nutrition label provides more useful information than relying on the product category alone.
Does Cooking Affect Folate?
Folate can be sensitive to heat and water.
Some folate may be lost during cooking, particularly when foods are boiled for long periods and the cooking water is discarded.
This does not mean vegetables should not be cooked.
Different cooking methods can preserve different nutrients, and cooked vegetables can still be highly nutritious.
The Simple Takeaway
Folate is vitamin B9 and plays an important role in DNA production, cell division, and normal red blood cell formation.
Remember:
- Folate is a B vitamin.
- Folic acid is a form of vitamin B9 used in supplements and fortified foods.
- Leafy greens, beans, lentils, peas, and some fruits provide folate.
- Fortified grain products can provide folic acid.
- Folate is especially important during pregnancy and early development.
