Does Folate Help You Conceive?

The key message

Start taking folate three months before you begin trying to conceive. It can take up to three months to fully replenish folate stores, and around 35% of women of reproductive age in the UK have a folate deficiency. If you have been taking the oral contraceptive pill, folate levels may also take up to three months to return to normal after stopping.

This matters because the neural tube develops in the first 28 days of pregnancy, often before you know you are pregnant. Folate also supports DNA creation and repair, healthy placenta growth, and helps manage homocysteine levels. Folate-rich foods are helpful, but diet alone may not be enough, so speak to a healthcare professional before starting a supplement.

Introduction

One of the most widely studied and essential nutrients for fertility is folate.

This article explores why it is critical for women to start taking folate three months before they begin trying to conceive.

What Is Folate?

Folate is a B-vitamin that is crucial for numerous bodily functions. It is naturally present in foods like leafy greens, lentils, and whole grains. The synthetic version, known as folic acid, is commonly found in over-the-counter supplements and is also added to processed foods.

Around 35% of women of reproductive age in the UK have a folate deficiency. It can take up to three months to fully replenish folate stores, which is essential for a healthy pregnancy.

Did you know that taking the oral contraceptive pill can reduce folate levels? It may take up to three months after discontinuing the pill for folate levels to return to normal.

Why Is Folate So Important During Pregnancy?

1. Prevention of Neural Tube Defects: One of the key reasons folate is recommended before and during early pregnancy is to prevent neural tube defects (NTDs), which are serious birth defects affecting the brain and spine. These defects often develop very early in pregnancy, before many women even know they are pregnant.
2. Supports DNA Synthesis: Folate is vital for DNA creation and repair. This process is especially important for the developing egg, which matures over three months prior to ovulation. During early pregnancy, rapid cell division and DNA replication occur, so maintaining optimal folate levels helps ensure proper cell development.
3. Folate is involved in placenta formation, which provides vital nutrients to the growing baby during pregnancy.
