29 Vitamin B9 Foods Great for Physical & Mental Health

Vitamin B9 Foods

Vitamin B9, or folate, belongs to the B-complex family, which includes eight vitamins. They are all responsible for energy metabolism, meaning they help the body produce energy by breaking down carbohydrates, fats, and protein and converting them into usable energy.

If you keep on reading, you will find out more about other vital roles of folate and how you can improve your health with vitamin B9 foods. All in all, since it is indispensable to have a balanced diet, make sure you include all the essential nutrients.

What Is Vitamin B9?

As we have already said, vitamin B9 is also known as folate. This vitamin is water-soluble, which means that it is carried through the bloodstream and excreted in the urine if not used. The term folate, or vitamin B9, refers to several compounds (folates) naturally found in food, added to some food products, and found in dietary supplements.

Folate vs. Folic Acid

A folic acid is also a form of this vitamin, but it doesn’t exist in nature. Instead, it is synthetically made and usually used as a supplement. Folate is a coenzyme that is of great importance for several reactions in our body. One of its most important functions is its role in the metabolism of amino acids and DNA and RNA synthesis.

Vitamin B9 Benefits

Apart from participating in RNA and DNA synthesis, vitamin B9 contributes to cell division and growth. It is also responsible for the production of red blood cells and improving brain health. Besides these critical functions, the benefits of folic acid, in particular, include preventing several medical conditions.

Although further research is needed to confirm this link, there is a connection between folic acid and an autism spectrum disorder. Namely, taking a folic acid supplement before conception and during pregnancy may decrease the risk of this developmental disorder.

Vitamin B9 and other B vitamins are also known for lowering the levels of homocysteine — a common amino acid that can mediate the formation of cardiovascular disease. According to a recent study, supplements of folic acid can also reduce the risk of stroke.

Folic Acid and Pregnancy

As vitamin B9 plays a significant role in synthesizing DNA, pregnant women are often advised to increase their intake of this vitamin. Moreover, folic acid has been proven to prevent neural tube defects (NTDs). Since they happen in the first month of pregnancy, it’s recommended that women take a folic acid supplement before and during pregnancy.

Furthermore, vitamin B9 might reduce the risk of preterm birth and minimize the risk of congenital disabilities, especially heart defects. Therefore, in addition to consuming sufficient amounts of foods rich in vitamin B9, women are advised to continue taking supplements of folic acid during pregnancy. Make sure you keep this in mind when planning for pregnancy.

Folate Recommended Daily Intake

The Food and Nutrition Board (FNB) devised the Dietary Reference Intakes, which lists the recommended daily values for all the nutrients, including folate.

Below you can see the Recommended Dietary Allowances (RDAs) for folate. They are expressed in mcg of dietary folate equivalents (DFEs), which can be converted to mcg of food folate or mcg of folic acid as follows:

  • 1 mcg DFE = 1 mcg food folate
  • 1 mcg DFE = 0.6 mcg folic acid from fortified foods or dietary supplements taken with food
  • 1 mcg DFE = 0.5 mcg folic acid dosage from dietary supplements taken on an empty stomach

RDAs for vitamin B9 vary depending on age:

  • from birth to 6 months — 65 mcg DFE
  • from 7 to 12 months — 80 mcg DFE
  • from 1 to 3 years — 150 mcg DFE
  • from 4 to 8 years — 200 mcg DFE
  • from 9 to 13 years — 300 mcg DFE
  • 14+ years — 400 mcg DFE

It’s important to emphasize that pregnant women should take 600 mcg DFE, and breastfeeding women need 500 mcg DFE.

Vitamin B9 Deficiency

A poor diet lacking folate can result in a deficiency in this nutrient. Besides a low intake of vitamin B9, alcohol use disorder and malabsorptive disorders may also lead to vitamin B9 deficiency. That’s why people with a deficiency in vitamin B9 are usually deficient in other nutrients as well.

This type of deficiency can cause megaloblastic anemia, with symptoms as follows:

  • weakness
  • fatigue
  • headaches
  • problems with concentration
  • heart palpitations

Other folate deficiency symptoms include:

  • ulcerations on the tongue
  • mouth sores
  • pigmentation changes
  • higher levels of homocysteine
  • gastrointestinal problems

Women with lower concentrations of folate are more likely to give birth to infants with NTDs. In addition, they are at higher risk of preterm delivery and giving birth to infants with low birth weight.

Who Should Take Vitamin B9 Supplements?

Women of childbearing age are recommended to take folic acid supplements to lower the risk of NTDs and other congenital disabilities. Also, considering the importance of folic acid for pregnancy, pregnant women need to take multivitamins or dietary supplements with folic acid. This vitamin is crucial for nucleic acid synthesis — producing a complex organic substance present in living cells, especially RNA and DNA.

Not only do alcoholics have poor diets, but they also have problems with the absorption of folate because of alcohol. Therefore, they can benefit from taking supplements to either prevent or treat folate deficiency.

Furthermore, certain medical conditions can affect the levels of folate as well. For example, malabsorptive disorders, like celiac disease and inflammatory bowel disease, may cause nutrient deficiency. Also, people with MTHFR polymorphism should take supplements since this medical condition affects the conversion of folate to its active form.

Side Effects of Vitamin B9

Since a high intake of folate can alleviate some symptoms of vitamin B12 deficiency, there is a possibility that high doses of vitamin b9 supplements can “hide” this deficiency, which can cause neurological damage if not treated. Moreover, a large amount of folic acid may increase the risk of certain cancers.

If you take high doses of folic acid, your body might not be able to transform it into the active form of folate, which results in unmetabolized folic acid in the body. That can affect your immune system as unmetabolized folic acid may reduce the number and activity of natural killer cells.

The FNB provided Tolerable Upper Intake Levels for the synthetic forms of folate used in supplements and fortified foods. They don’t apply to those who take dietary supplements under medical supervision. That said, there isn’t conclusive evidence that folate from food sources can cause adverse effects on our health.


Folate is necessary for several vital functions in our body, such as producing red blood cells and synthesizing DNA. Another essential vitamin B9 function is the prevention of neural tube defects. Therefore, women of childbearing age and pregnant women are advised to increase their vitamin intake.

People with a healthy, balanced diet are unlikely to develop a deficiency as there is a wide range of folate foods, including meat, fish, dairy products, vegetables, and fruits.

That said, certain groups of people are recommended to take folic acid as a supplement. Still, you shouldn’t take dietary supplements without medical supervision as high doses may have side effects.


What does vitamin B9 do?

Vitamin B9, or folate, plays numerous crucial roles in our body. It is responsible for the production of red blood cells, the synthesis of DNA and RNA, and cell division and growth. Other B9 vitamin benefits include contributing to brain health and promoting normal fetal growth and development. That’s why it is of great importance to pregnant women and women planning to get pregnant.

Is vitamin B9 the same as folic acid?

Vitamin B9 is the umbrella term for many folates naturally found in food and folates found in fortified food products and supplements, including folic acid. Therefore, folic acid is just one form of vitamin B9, made synthetically.

Does folic acid have side effects?

It is believed that a high intake of folic acid can mask a vitamin B12 deficiency, which can pose a significant health risk since it’s imperative to treat this type of deficiency on time. Otherwise, it can lead to severe neurological damage.

Also, your body may not be able to transform high doses of folic acid into the active form of vitamin B9. Consequently, unmetabolized folic acid can damage your immune system.

What is vitamin B9 deficiency?

This deficiency is a medical condition characterized by low levels of folate. Some of the vitamin B9 deficiency symptoms are fatigue, mouth sores, and tongue swelling. Moreover, B9 deficiency can be caused by a poor diet, alcoholism, and malabsorptive disorders, such as celiac disease and inflammatory bowel disease. Sometimes, folate deficiency causes anemia. Its symptoms include weakness, shortness of breath, and irritability.

Who needs folic acid the most?

Women should take folic acid before pregnancy or during pregnancy, as it helps prevent severe congenital disabilities. In addition, you can get folic acid from food or supplements. Namely, it can be found in fortified rice, bread, pasta, and cereals.

How can I increase my folate intake?

You can quickly increase your folate intake by consuming foods rich in this vitamin. Thankfully, folate is easily found in many foods. Thus, people with various diets can cover their recommended daily intake without any problems.

What foods are high in vitamin B9?

Folate is naturally found in numerous foods, including meat, fish, seafood, eggs, dairy products, fruits, and vegetables. As for folic acid, it is often added to cereals, bread, pasta, rice, and flour.

Vitamin B9 foods that are exceptionally high in folate include various sorts of beans and peas, asparagus, spinach, turnip greens, and other green leafy veggies.
