Is it necessary to stop taking folic acid after three months?

Folic acid supplementation should not cease after just three months. Folic acid is a crucial nutrient during pregnancy and preconception, and it is recommended to continue taking it for the three months before pregnancy and throughout the entire pregnancy period. Folic acid helps prevent neural tube defects in fetuses, and women may have different intake needs at different stages. It is advisable to supplement folic acid under the guidance of a healthcare professional.

1. Why Folic Acid is Needed: Folic acid, also known as vitamin B9, is an essential element for synthesizing nucleic acids and cell growth and division. Pregnant women have an increased demand for folic acid due to the extensive cell division and growth required for fetal development. Experts point out that adequate folic acid intake can effectively prevent neural tube defects in fetuses, such as spina bifida and anencephaly.

2. When to Start Supplementing with Folic Acid: It is recommended that women start supplementing with folic acid at least three months before planning to get pregnant and continue supplementing during the early stages of pregnancy, particularly the first trimester. The U.S. Centers for Disease Control and Prevention recommends a daily intake of 0.4 to 0.8 milligrams of folic acid for pregnant women to provide sufficient folic acid during the critical period of neural tube formation.

3. Folic Acid Supplementation During Pregnancy: Although the first trimester is the most critical period for folic acid supplementation, moderate supplementation is also needed throughout pregnancy and even lactation to support the health of both the mother and fetus. Sources of folic acid are not limited to supplements; various natural foods, such as green leafy vegetables, citrus fruits, and whole grain products, are also rich in folic acid. The duration of folic acid supplementation should be determined based on individual needs and specific health conditions. Continuous folic acid supplementation throughout pregnancy not only supports healthy fetal development but also helps reduce the risk of pregnancy complications. To avoid folic acid deficiency and ensure the health of pregnant women and fetuses, it is best to adjust folic acid intake under medical guidance and consider folic acid sources in daily diet.
