Quizplus · Accepted Answer

Adequate folate is most important during the first four weeks of pregnancy because this is the time when the neural tube is forming and the risk of neural tube defects is highest. Folate helps in the proper development of the neural tube and the prevention of these defects. It is recommended that women of childbearing age take a daily supplement of 400-800 micrograms of folic acid, even if they are not planning to become pregnant, to ensure adequate folate levels.
