Folic Acid – Why Is It Vital and How Does It Affect the Body?

What Is Folic Acid and Why Is It Important for the Human Body

Folic acid is a type of water-soluble vitamin belonging to the B-vitamin group. It is also known as vitamin B9.
It naturally enters the body through food and is synthesized by bacteria living in the intestines.
It is essential for the bone marrow. It participates in the synthesis of neurotransmitters that support normal appetite, sleep, and mood, and help reduce the development of oncological diseases.

Folic acid deficiency increases the risk of anemia, fatigue, weakness, irritability, and shortness of breath.

What Is Folic Acid and Why Is It Important for the Human Body

Folic acid is a water-soluble vitamin from the B-vitamin group that plays a role in cellular metabolism, DNA and RNA synthesis, and the formation of red blood cells.

Folic acid is essential for the normal functioning of our nervous system, immune defense, and energy metabolism.

It helps prevent anemia, supports tissue growth, and improves brain function.

In the human body, folic acid is converted into its active form, tetrahydrofolate, which participates in many biochemical processes.

Our body needs a constant supply of folic acid. This vitamin cannot be produced independently in sufficient amounts. It is important to be aware of this.

Folic acid deficiency can have serious consequences. These include impaired hematopoietic function, digestive problems, weakened immunity, and even cognitive disorders.

Adequate intake of folic acid is especially important for pregnant women, as deficiency can negatively affect the proper development of the fetus.

What Is the Difference Between Folic Acid and Folate?

Folic acid is the synthetic form of vitamin B9.
The natural form of this vitamin, which we obtain from food, is called folate.However, many people absorb the synthetic vitamin better when taken as a supplement.
That is why these terms are often used interchangeably when discussing folic acid.
The daily intake of folic acid is 400 mcg.
Vitamin deficiency is significantly more important.

How Does Folic Acid Work in the Body

Want to feel more energetic? Check whether you may need folic acid.
Your body needs folic acid for cell growth and reproduction, creating essential building blocks.
Folic acid is responsible for the production of genetic material.
Research has found that proper intake of folic acid may help protect against heart disease, stroke, and certain types of cancer. A deficiency of this vitamin may lead to anemia or depression.
We are not able to store large amounts of folic acid in our bodies, so it is important to consume it every day — either through food or supplements.

The recommended daily intake for adults is 400 mcg.

Why Is Folic Acid Essential During Pregnancy

Folic acid is especially important for pregnant women.
Taking the right amount of vitamin B9 is especially important for women, as it is essential for the normal development of the fetal nervous system during pregnancy.

Folic acid deficiency can lead to serious fetal developmental disorders and may affect the baby’s development even before the mother realizes she is pregnant.

That is why doctors recommend not relying only on natural B9 intake, but also taking 400 mcg of folic acid as a supplement.

During pregnancy, this amount may increase to 600 mcg, as prescribed by the attending physician.

Folic Acid When Planning Pregnancy and During Pregnancy

Vitamin B9 deficiency in pregnant women may cause fetal malformations such as spina bifida (spinal cord defect) or anencephaly (absence of cerebral hemispheres).

Taking the proper amount of folic acid helps protect the baby from birth defects.

In addition, B9 deficiency during pregnancy increases the risk of preeclampsia, premature birth, and low birth weight.

Folic acid helps maintain normal cardiovascular function in the mother and may help prevent premature birth.

It also helps reduce the risk of miscarriage and the birth of a low-weight baby.

We can confidently say that adequate levels of folic acid are crucial for the health of the expectant mother and the proper development of the baby.

The Importance of Folic Acid for Hormonal Balance in Women

Folic acid helps balance a woman’s hormones, which in turn supports emotional well-being.
This vitamin is effective even during PMS, when the body experiences significant hormonal imbalance.
The body of women in their forties and fifties undergoes major hormonal changes.
Folic acid supports hormonal balance.
Folic acid supports the production and regulation of reproductive hormones, including estrogen and progesterone. These hormones are essential for ovulation, embryo implantation, and maintaining a healthy early pregnancy.

The Importance of Folic Acid for the Female Body

• Folic acid participates in the production of platelets, white blood cells, and red blood cells;
• Supports the repair of damaged tissues;
• Stimulates the formation of new cells and cell division;
• Participates in amino acid synthesis;
• Participates in DNA reproduction.
Folic acid is an important nutrient for maintaining women’s health, influencing fertility and proper fetal development.

How Else Does Folic Acid Benefit Women Over 30, 40, and 50?

Folic acid is the foundation of immunity.
Folic acid, or B9, participates in the synthesis of immunoglobulins — proteins that activate the body’s defenses against viruses and bacteria.
Stimulates brain function.
Vitamin B9 acts as a nootropic: it improves mental performance, memory, and concentration, increasing productivity.

Relieves nervous tension.

Folic acid participates in the synthesis of neurotransmitters that regulate mood, appetite, and sleep. It helps maintain balance during emotional instability and increases resistance to stress.
Improves the condition of the skin, hair, and nails.


It protects the skin from UV rays and age spots. It also promotes the growth of nails and hair, making them stronger and preventing breakage.
Supports a slimmer figure.
It stimulates metabolism and fat burning, helping women maintain a slim and toned body in a healthy way.

The Importance of Folic Acid for Breastfeeding Women

• Stimulates breast milk production;
• Helps prevent postpartum depression;
• Provides the newborn with the necessary folate.

What Are the Symptoms of Folic Acid Deficiency?

The main symptoms of folic acid deficiency include:
pale mucous membranes, anxiety, fatigue, insomnia, depressive states, memory impairment, digestive disorders, skin peeling and redness, stomatitis, as well as folate-deficiency anemia.

What Are the Risks of Folic Acid Deficiency?

Impaired folic acid metabolism in the body leads to elevated levels of total homocysteine in the plasma, which may increase the risk of thrombosis and the development of coronary heart disease, myocardial infarction, and stroke.
High homocysteine levels are associated with pregnancy complications (recurrent miscarriages, placental insufficiency, fetal growth restriction, intrauterine death, placental abruption, premature birth) and fetal malformations (Down syndrome, encephalomeningocele, myelomeningocele, etc.).

How Is Folic Acid Deficiency Diagnosed?

A blood test is required.

• It is important to prepare properly for the procedure to ensure reliable blood test result
• Blood should be drawn for analysis in the morning before 11:00 AM on an empty stomach (at least 8 hours without food; water is allowed).
  
• Consult your doctor in advance regarding the appropriateness of testing while taking medications or the possibility of stopping them before the test.
  
• Avoid alcohol the day before the test and do not smoke for 1 hour before testing.
  
• It is recommended to avoid physical or emotional stress the day before the test.
  
• After arriving at the laboratory, rest for 10–20 minutes before the blood sample is taken.
  
• It is not recommended to donate blood for laboratory testing shortly after physiotherapy, diagnostic procedures, or other medical treatments.
  

In the early stages, symptoms of vitamin B9 deficiency are often subtle and nonspecific. They are easily ignored or attributed to fatigue, stress, or dietary mistakes.

The first clear symptoms of B9 deficiency include:
• lack of energy and constant fatigue;
• digestive problems including loss of appetite, nausea and vomiting, diarrhea, and abdominal pain;
• glossitis – inflammation of the tongue;
• stomatitis – inflammation of the oral mucosa;
• headaches;
• difficulty concentrating;
• pale skin.

Long-term folic acid deficiency can lead to serious complications.
Complications that may develop due to vitamin B9 deficiency include:
• folate-deficiency anemia – a condition in which the number of red blood cells decreases while the number of megaloblasts, their precursors, increases, making them unable to effectively deliver oxygen to tissues and organs;
• depression;
• peripheral neuropathy – pain, weakness, and loss of sensation in the hands and feet.
• In rare cases, folate deficiency may lead to psychosis, delirium, and other serious neuropsychiatric disorders.
