The optimal time to start taking folic acid is at least three months before you conceive and continuing until you're 12 weeks pregnant. This allows sufficient levels to build up in your body, significantly reducing the risk of neural tube defects in your baby.
Why Take Folic Acid Before and During Pregnancy?
Folic acid, a form of vitamin B9, is crucial for healthy cell growth and function, particularly during early pregnancy. It plays a vital role in the development of the neural tube, which forms the brain and spinal cord. Adequate folic acid intake helps prevent neural tube defects, serious birth defects that can occur during the first few weeks of pregnancy, often before a woman even realizes she's pregnant.

Recommended Dosage and Intake
The recommended daily dose is generally 400 micrograms (mcg). This can be achieved through a daily supplement or by incorporating folate-rich foods into your diet. However, it's important to note that dietary folate alone may not be sufficient to meet the necessary levels, hence the recommendation for supplementation. [Source: NHS, ACOG, Canada.ca]

Important Note: Always consult your doctor or midwife for personalized advice on folic acid supplementation, particularly if you have pre-existing health conditions or are taking other medications. [Source: NHS]
Sources of Folic Acid
While supplements are recommended, folate is naturally found in many foods such as leafy green vegetables, legumes, and citrus fruits. However, relying solely on dietary sources might not ensure sufficient levels, hence the importance of supplementation. [Source: CDC, WebMD]
