When Should You Start Folic Acid Before Pregnancy?

Folic acid (folate) is a B vitamin that helps the body make new cells. It is especially important in the first weeks of pregnancy, when the baby's brain and spinal cord are forming, often before a woman even knows she is pregnant.

When to start

Health authorities generally recommend that women who are planning a pregnancy, or who could become pregnant, start a daily folic acid supplement at least one month before conception. Starting early means folate levels are already good when they are needed most.

How long to continue

Folic acid is usually continued through at least the first 12 weeks of pregnancy. Many doctors then switch women to a complete prenatal vitamin for the rest of pregnancy and breastfeeding. Some women need a higher dose, so follow your doctor's advice.

Why vitamin B12 matters too

Folate and vitamin B12 work closely together in making red blood cells and new cells. Low B12 is more common in vegetarians, older adults and people with some digestive conditions, so many formulas combine both.

Food sources of folate

• Dark leafy greens such as spinach and molokhia
• Lentils, chickpeas and beans
• Oranges and citrus fruits
• Fortified bread and cereals

Food alone is often not enough before and during early pregnancy, which is why a supplement is recommended.

Choosing a supplement

Bio Trifol combines folic acid with vitamin B12 and vitamin B6 in one daily tablet, suitable for the pregnancy-planning stage. For a complete formula during pregnancy and breastfeeding, see Bio Pregnant.
