Folic Acid (fertility)

What is Folic Acid (fertility)?

Folic acid, also known as vitamin B9, is an essential water-soluble vitamin that plays a crucial role in the body's cell growth and division. It is especially important for women planning to become pregnant, as it helps prevent neural tube defects in the unborn child. Folic acid is also necessary for the early development of the embryo, making it critical to obtain sufficient amounts even before conception.

How does it work in the body?

Folic acid functions by supporting the production of DNA and RNA, as well as aiding in the formation of red blood cells. It helps reduce homocysteine levels, which is important for cardiovascular health. In relation to fertility, folic acid plays a central role in ensuring healthy cell growth and development, which is vital during the early stages of pregnancy.

Scientific benefits

Several studies have shown folic acid as an important factor in pregnancy outcomes. According to a study published in The Lancet, folic acid intake reduces the risk of neural tube defects by up to 70%. Other studies have shown that women who receive adequate amounts of folic acid have a higher chance of a successful pregnancy. It has also been suggested that folic acid may improve egg quality in women undergoing fertility treatments.

• Neural tube defects: Folic acid reduces the risk of defects in the brain and spinal cord.
• Pregnancy outcomes: Increases the chances of a successful pregnancy.
• Egg quality: Improves egg quality in women seeking fertility treatment.

Dosage and recommendations

The recommended daily dose of folic acid for women planning to become pregnant is 400 micrograms (µg) per day. This should begin at least one month before conception and continue throughout the first trimester. For women with a previous pregnancy resulting in neural tube defects, higher doses, up to 5 mg per day, may be recommended.

Best sources and forms

Folic acid is found in many foods, including:

• Green leafy vegetables (e.g., spinach, broccoli)
• Legumes (e.g., lentils, beans)
• Whole grain products
• Nuts and seeds
• Citrus fruits

Folic acid is also available as a dietary supplement, which can be useful for women who have difficulty obtaining sufficient amounts through diet.

Side effects and warnings

Folic acid is generally considered safe when taken at recommended doses. However, high doses can mask vitamin B12 deficiency, which may lead to neurological problems. It is important to consult a doctor before starting supplements, especially if there is a history of vitamin deficiencies.

Frequently asked questions

1. When should I start taking folic acid if I plan to become pregnant?

It is recommended to start taking folic acid at least one month before conception and continue during the first trimester.

2. Can I get enough folic acid through diet?

Yes, many foods contain folic acid, but it can be difficult to get sufficient amounts from diet alone. Supplements may be necessary.

3. What happens if I miss a dose of folic acid?

If you miss a dose, take it as soon as possible. If it is almost time for the next dose, skip the missed dose and continue with your regular schedule.

4. Are there any risks of taking too much folic acid?

High doses of folic acid can mask vitamin B12 deficiency and lead to neurological problems, so it is important to follow recommended doses.

5. Is folic acid good for men who want to become fathers?

Although folic acid primarily focuses on female health during pregnancy, some research suggests that folic acid may support sperm quality.
