How to Properly Take Folic Acid During Pregnancy: Recommendations and Tips

Highlights

• Folate (also known as folic acid) is one of the B vitamins that supports healthy growth and development.
• Folate is found naturally in foods, and it is known as ‘folic acid’ when added to foods or included in dietary supplements.
• Your baby needs folate for brain, spine, and nerve development.
• Taking folic acid supplements during pregnancy helps prevent birth defects.
• Folic acid supplements are widely available — ask your healthcare provider about the dose that’s right for you.

Folate and Folic Acid

Folate, or vitamin B9, is an essential nutrient needed for healthy growth and development. It occurs naturally in foods such as leafy greens, fruits, and legumes. When used in supplements or added to foods, it is called folic acid. This vitamin is crucial for cell division and DNA formation, which makes it especially important during pregnancy.

Folic acid is the synthetic form of folate commonly used in supplements and fortified foods. It is efficiently absorbed, providing a reliable way to increase folate intake, particularly if dietary sources are insufficient.

Importance of Folate During Pregnancy

Folate plays a key role in preventing neural tube defects, such as spina bifida. Neural tube defects occur early in pregnancy, often before a woman knows she is pregnant.

Adequate folate levels before conception and during early pregnancy are essential for reducing this risk. It is recommended to begin folic acid supplementation before becoming pregnant and continue through the first trimester.

Foods Containing Folate

Many foods naturally contain folate. Including these in your diet helps maintain healthy folate levels:

• Vegetables: Broccoli, spinach, Brussels sprouts, cabbage, cauliflower, green beans, zucchini, lettuce
• Fruits: Oranges, avocados, bananas, strawberries, grapefruit
• Legumes: Chickpeas, lentils, kidney beans, soybeans, peas
• Eggs
• Nuts
• Juices: Especially citrus juices
• Fortified foods: Some bread, cereals, and grain products

Folate can be degraded by heat, so steaming, microwaving, or eating raw vegetables can help preserve it.

Starting Folic Acid Supplements

Ideally, folic acid supplements should be started at least one month before trying to conceive. This helps the body build sufficient folate levels. Continuing supplementation through the first trimester is recommended.

If supplementation was not started before pregnancy, it should begin as soon as pregnancy is confirmed.

Folic acid supplements are commonly available in a variety of doses.

Recommended Dosage of Folic Acid

A standard recommended dose when trying to conceive or during early pregnancy is at least 400 micrograms (mcg) per day. Many supplements contain 500 mcg and are considered safe and effective.

It is important to avoid excessive intake from multiple supplements. A healthcare provider can help determine the right dose based on your needs.

High Dose of Folic Acid

A higher dose may be recommended for individuals at increased risk of neural tube defects. Risk factors can include:

• A personal or family history of neural tube defects
• A previous affected pregnancy
• Diabetes or obesity
• Using certain medications
• Conditions that reduce nutrient absorption

In such cases, a high-dose supplement (often 5 mg per day) may be advised before pregnancy and through the first trimester.

Excessive Folic Acid Intake

Folic acid is water-soluble, and excess amounts are generally excreted. However, long-term overconsumption may mask signs of vitamin B12 deficiency, which can delay diagnosis and cause neurological issues.

If you suspect excessive intake, contact a healthcare professional for guidance.
