What is Folic Acid used for?
Generally, Folate is found in citrus fruits and dark green vegetables. The artificially created vitamin B9 is termed Folic Acid. The general folic acid function includes creating genetic material, human body development and red blood synthesis. The four significant Folic acid uses in our daily life can be classified under four heads:
a) Folic Acid for Pregnancy
b) Folic Acid benefits for men
c) Folic Acid benefits for skin
d) Folic acid benefits for hair
a) Folic Acid for Pregnancy:
One of the major folic acid benefits is enriching the foetus and preventing defects at the time of giving birth. The intake of folic acid during pregnancy guards the baby against neural tube defect, miscarriage, low birth weight, premature birth and weak growth in the womb.
b) Folic Acid benefits for Men:
Folic acid is a very essential ingredient from the men’s health perspective. It stabilizes the sperm count which eventually assists in the procedure of conception. Hence, Folic acid is a must for would-be fathers.
c) Folic Acid benefits for Skin:
Folic acid encourages the maintenance of the natural beauty of the skin. The main folic acid functions in the skin include its role as anti-ageing, antioxidant and moisturizer material. The quality of the skin is enhanced by the application of Folic acid. Acne and dead cells are treated by folic acid. The dead cells are removed very effectively by it. Hence, the skin remains healthy with a natural glow.
d) Folic Acid benefits for Hair:
Folic acid plays a crucial role in the growth of hair. The procedure of blood circulation in the scalp is regulated by Folic acid. Premature greying of hair and hair loss is caused by the deficiency of Folic acid or folate.
e) Other uses of Folic Acid are:
Gives support to the digestive system.
Cures depression.
Restricts diabetes.
Folic acid is an important ingredient in preventing cancer and memory loss.
Different infections such as gum infection are cured by folate.
It is good for the heart.

What is the difference between Folic Acid and Folate?
Different types or forms of vitamin B9 are termed folic acid and folate. The natural form of vitamin B9 in food is called folate whereas the synthetic form of the same is termed folic acid. The basic difference between the two is that a folic acid is an artificial form of vitamin B9 which is manmade while folate is the naturally found vitamin B9.
What is the Dosage of Folic Acid?
Folic acid, as already mentioned before, is a synthetic product available in the form of tablets in the market. The naturally occurring folic acid, or folate to be precise, can be taken through food. The recommended dietary allowance of folic acid for an adult is 1mcg. The following table contains the dietary folate requirements:
Did You Know?
Hair loss can be prevented by the regular intake of Folic acid. Doctors have suggested after various researches that folic acid can be a significant supplement for the growth of hair. The basic folic acid function is maintaining healthy cell growth. Cells are found in skin tissues, hair and nails and they do not differ from each other. Thus folic acid can be considered as a possible hair growth treatment measure. When it comes to cells, the red blood cells are also nurtured by this particular compound.
The folic uses are myriad. Thus it is one of the essential nutrients that must be taken according to the RDA and foods rich in this nutrient should be included in the daily diet.
FAQs on Uses of Folic Acid in Human Health and Biochemical Processes
1. What are the main uses of folic acid?
The main uses of folic acid (vitamin B9) are to support DNA synthesis, red blood cell formation, and prevent neural tube defects during pregnancy. It is commonly used for:
- Treatment and prevention of megaloblastic anemia caused by folate deficiency
- Prenatal supplementation to reduce the risk of spina bifida and other neural tube defects
- Supporting cell division and growth
- Lowering elevated homocysteine levels in the blood
- Managing folate deficiency due to poor diet, malabsorption, or certain medications
Because folic acid is essential for rapidly dividing cells, it is especially important during pregnancy and infancy.
2. What is folic acid and what is its chemical formula?
Folic acid is a water-soluble B-vitamin (vitamin B9) with the chemical formula C19H19N7O6. It is chemically known as pteroyl-L-glutamic acid and consists of:
- A pteridine ring
- p-aminobenzoic acid (PABA)
- A glutamic acid residue
In the body, folic acid is converted into its active form, tetrahydrofolate (THF), which participates in one-carbon transfer reactions essential for DNA synthesis.
3. How does folic acid help in DNA synthesis?
Folic acid helps in DNA synthesis by forming tetrahydrofolate (THF), which transfers one-carbon units required for nucleotide production. Specifically, THF is involved in:
- Synthesis of purine bases (adenine and guanine)
- Conversion of dUMP to dTMP in thymine formation
- Rapid cell division and replication
Without adequate folic acid, DNA synthesis is impaired, leading to abnormal cell division and conditions like megaloblastic anemia.
4. Why is folic acid important during pregnancy?
Folic acid is important during pregnancy because it prevents neural tube defects (NTDs) in the developing fetus. During early embryonic development:
- The neural tube forms within the first 28 days
- Adequate folate ensures proper DNA synthesis and cell division
- It reduces the risk of spina bifida and anencephaly
Women of childbearing age are often advised to take folic acid supplements before and during early pregnancy.
5. What is the difference between folic acid and folate?
The main difference between folic acid and folate is that folic acid is the synthetic form, while folate is the naturally occurring form in foods. Key differences include:
- Folic acid: Synthetic, used in supplements and food fortification
- Folate: Naturally found in leafy greens, legumes, and fruits
- Folic acid must be converted in the liver to tetrahydrofolate (THF) to become biologically active
Both forms ultimately function in one-carbon metabolism and DNA synthesis.
6. How does folic acid prevent megaloblastic anemia?
Folic acid prevents megaloblastic anemia by enabling normal DNA synthesis in red blood cell precursors. In folate deficiency:
- DNA replication is impaired
- Cell division slows down
- Large, immature red blood cells (megaloblasts) are formed
Supplementing folic acid restores proper nucleotide synthesis, allowing normal maturation of red blood cells in the bone marrow.
7. Can folic acid lower homocysteine levels?
Yes, folic acid lowers homocysteine levels by converting homocysteine into methionine in a methylation reaction. In this process:
- 5-methyltetrahydrofolate donates a methyl group
- Homocysteine is converted to methionine
- Vitamin B12 acts as a cofactor
Reducing elevated homocysteine may help decrease the risk of cardiovascular diseases.
8. What foods are rich in folic acid or folate?
Foods rich in folate include leafy green vegetables, legumes, and fortified grains. Common sources are:
- Spinach, kale, and broccoli
- Lentils, chickpeas, and beans
- Citrus fruits
- Fortified cereals containing folic acid
A balanced diet with these foods helps maintain adequate folate levels for normal cellular and metabolic functions.
9. What happens if you have a folic acid deficiency?
A folic acid deficiency leads to impaired DNA synthesis and can cause megaloblastic anemia and developmental defects. Common effects include:
- Fatigue and weakness
- Pale skin due to anemia
- Glossitis (inflamed tongue)
- In pregnancy, increased risk of neural tube defects
Long-term deficiency may also result in elevated homocysteine levels.
10. How is folic acid chemically activated in the body?
Folic acid is chemically activated by reduction to tetrahydrofolate (THF) via the enzyme dihydrofolate reductase (DHFR). The activation occurs in two steps:
- Folic acid → dihydrofolate (DHF)
- DHF → tetrahydrofolate (THF)
THF then participates in one-carbon transfer reactions essential for amino acid metabolism and nucleotide synthesis.
