What is the recommended daily dose of folic acid during pregnancy?

1mg daily
5mg daily
10mg daily
15mg daily

The correct answer is: 5mg daily

The recommended daily dose of folic acid during pregnancy is typically 400 micrograms (0.4 mg) for most women, with an increased dose of 5 mg recommended for women with a higher risk of neural tube defects, such as those with a personal or family history of these conditions, or those with certain medical conditions. The choice of 5 mg as the answer reflects the guidelines issued by health organizations recommending this higher dosage in specific scenarios. It's essential to emphasize that although 1 mg is sometimes a general recommendation for women trying to conceive or early in pregnancy, it does not cover the increased risk population effectively. Similarly, doses of 10 mg and 15 mg are typically not recommended for routine use during pregnancy, as they exceed the necessary dietary supplementation for most women and can lead to unnecessary side effects. Folic acid’s role in preventing neural tube defects emphasizes the importance of adhering to these guidelines to ensure proper fetal development.
