Folic Acid During Pregnancy: Essential Guide for Pregnant Women

“Are you taking folic acid?” is often one of the first questions you hear when you mention that you wish to become pregnant or are pregnant. Why, you might ask, when your mother didn’t take it and you were born perfectly healthy? Since the 1990s, a wealth of scientific research has been conducted to determine the best ways to support women who wish to conceive and those who are pregnant. Based on this data, the Health Council issued advice in 2021, placing folic acid at the top of the list. Here’s why: let’s delve in! 

What is Folic Acid?   

Folic acid is a water-soluble vitamin, also known as vitamin B11. It plays a crucial role in your body and is necessary for the production of red blood cells and the proper functioning of the nerves. B11 comes in two forms: folic acid and folate. Folate is the natural form found in foods such as bananas, oranges, legumes, milk, whole grains, and leafy green vegetables. Folic acid is the synthetic version. Although the terms are often used interchangeably, it is important to remember that folate is more easily absorbed by the body.

Why is Folic Acid Important During Pregnancy?   

Folic acid is essential for women who are pregnant or planning to become pregnant. It contributes to healthy blood formation, the development of the placenta, and the growth of your baby. In the early weeks of pregnancy, it is crucial for the development of your baby’s central nervous system. It can reduce the risk of birth defects such as spina bifida, provided that you start taking it at least 4 weeks before conception. A deficiency can lead to symptoms such as anaemia, dizziness, fatigue, and digestive issues.  

When to Start Taking Folic Acid Before Pregnancy?   

The Health Council stresses the importance of starting folic acid and vitamin D supplements early when planning a pregnancy, at least 4 weeks before conception. Although this is not new information, studies show that many pregnant women either do not take these supplements or start too late. An unnoticed folic acid deficiency can lead to anaemia, while during pregnancy, up to 50% more blood production is needed to support your baby’s growth. Besides folic acid, the Health Council also advises starting vitamin D early. It can reduce the risk of preterm birth, gestational diabetes, low birth weight, and asthma-like symptoms in your baby. It is therefore wise to take these supplements.  

How Much Folic Acid to Take Per Day Before and During Pregnancy?    

From the moment you wish to conceive, it is advisable to start taking 400 to 500 mcg of folic acid per day. Many women use a pregnancy multivitamin that already contains the right dosage of folic acid, as well as other nutrients such as vitamin D, iron, and calcium, to prevent deficiencies. This pregnancy multivitamin can be used before, during, and after pregnancy. 

Until When Should You Take Folic Acid During Pregnancy?   

To help prevent neural tube defects, folic acid is beneficial up to 10 weeks after conception, as by this time, your baby’s nervous system has developed. If you are using a pregnancy multivitamin, which we encourage to optimally support your body, you can continue taking it.
