Folic Acid Deficiency: What 85% of Women Miss ?
If you are a woman of reproductive age in the UK, there is a significant chance your diet may not provide enough of a critical vitamin for a healthy pregnancy. The latest UK National Diet and Nutrition Survey, published in June 2025, reveals a concerning reality: 83% of women aged 16-49 have folate levels below the threshold recommended for preventing neural tube defects (NTDs). Folate is fundamental for healthy cell growth and DNA synthesis. To combat this widespread nutritional gap, the UK government has mandated that non-wholemeal wheat flour be fortified with folic acid by the end of 2026, a landmark public health measure aimed at preventing hundreds of devastating birth defects. [1][2] .
More Than a Pregnancy Nutrient:
Folate’s Role in a Balanced Diet
Folate is a vital nutrient with several health benefits officially recognised by the Great Britain Nutrition and Health Claims (NHC) Register. Its importance extends far beyond pregnancy, contributing to fundamental bodily processes. From supporting a healthy immune system to its role in blood formation, folate is a cornerstone of everyday nutritional wellbeing, underscoring the need for a diet rich in this essential vitamin.
Contributes to Normal Blood Formation: Folate is essential for producing healthy red blood cells. A deficiency can lead to megaloblastic anaemia, a condition where red blood cells are oversized and inefficient, causing fatigue, weakness, and shortness of breath. [3] .
Supports Normal Immune System Function: A well-functioning immune system is your body’s first line of defence. Adequate folate levels are crucial for the production and maintenance of immune cells, helping you stay resilient. [3] .
Contributes to the Reduction of Tiredness and Fatigue: By playing a key role in energy metabolism, folate helps your body convert food into usable energy, combating feelings of tiredness and fatigue.
Has a Role in the Process of Cell Division: Folate is a fundamental building block for DNA synthesis and repair. This process is essential for the growth, repair, and maintenance of every single cell in your body. [3] .
Understanding these functions highlights why a folate-rich diet is crucial for everyone. For those seeking to build a comprehensive nutritional strategy, exploring our complete range of Vitamins and Minerals can help ensure your body gets the synergistic support it needs.
“The UK’s decision to mandate folic acid fortification of flour is a landmark public health measure. It will prevent hundreds of devastating birth defects and improve the health of the nation, particularly that of women and their children.”

Are You at Higher Risk? Nutritional Factors That Increase Your Need For Folate
While mandatory flour fortification is a crucial step, it may not be sufficient for everyone. Certain lifestyle and health factors can significantly increase your body’s demand for folate, making a proactive nutritional approach essential.
Women of Childbearing Age
Increased folate demand for potential pregnancy; deficiency is highest in this group.
The neural tube forms in the first 28 days of pregnancy, often before a woman is aware she is pregnant. This makes pre-conception nutritional status absolutely critical. The NHS strongly advises a daily 400 mcg folic acid supplement for all women who could become pregnant to build adequate reserves.
Individuals with Poor Diets
Low intake of folate-rich foods like leafy green vegetables, legumes, and fortified grains.
Modern diets, often high in processed foods, can easily lack sufficient folate. Even with the upcoming flour fortification, a balanced diet rich in whole foods remains the cornerstone of good health and is essential for obtaining a wide range of nutrients.
Individuals with Malabsorption Issues
Conditions like coeliac disease or Crohn’s disease impair nutrient absorption from food.
For these individuals, even a folate-rich diet may not be enough to meet their body’s needs. Supplementation, often at a higher dose prescribed by a doctor, is typically necessary to maintain adequate nutritional status.
The NHS Recommendation: A Clear, Evidence-Based Nutritional Directive
The National Health Service (NHS) provides a clear, evidence-based directive: all women and people who could get pregnant should take a daily supplement of 400 micrograms (mcg) of folic acid before conception and continue for the first 12 weeks of pregnancy. This crucial public health guidance is aimed at preventing neural tube defects such as spina bifida and is based on extensive research into maternal and fetal nutritional needs. [4] .
“Taking folic acid before and during pregnancy is one of the most important things a mother can do for her baby. The evidence is clear that it significantly reduces the risk of life-altering neural tube defects.”

READY TO TAKE THE MOST IMPORTANT STEP FOR A HEALTHY PREGNANCY?
Our Folic Acid 400mcg supplement provides the exact daily dose recommended by the NHS, supporting maternal tissue growth and healthy fetal development during early pregnancy.
*While the NHS recommends a 400mcg folic acid supplement for most women who could become pregnant, individual nutritional needs can vary. Factors such as a family history of NTDs or specific health conditions may require a different approach. Our 800mcg option is available for those who, after consulting with a healthcare provider, determine a higher intake is appropriate.
What To Expect: A Pre-Pregnancy Timeline To Optimal Folate Status
Achieving optimal folate levels is a process that requires consistent nutritional intake before and during early pregnancy. Here is a general timeline of what you can expect as your body builds its folate reserves:
3 Months Before Pregnancy: Building Nutritional Reserves
Starting folic acid supplementation at least three months before trying to conceive is key. This period allows your body to build sufficient folate stores, which are crucial for the very early stages of fetal development, particularly neural tube formation.
During the first four weeks of pregnancy, folate plays a vital role in the closure of the neural tube. Having adequate levels is essential during this critical window, which often occurs before pregnancy is even confirmed.
Weeks 4-12: Supporting Maternal and Fetal Growth
Continued folic acid intake throughout the first trimester supports rapid cell division, maternal tissue growth, and overall fetal development, laying a strong nutritional foundation for a healthy pregnancy.
WHEN TO SEE A DOCTOR?
If you are planning a pregnancy, it is always a good idea to speak with your GP to discuss your individual nutritional needs. They can provide personalised advice and assess if you have any risk factors that may require a higher dose of folic acid.

1. How do I know if my diet is low in folate?
Symptoms of folate deficiency can be subtle, including fatigue or weakness. Since it’s hard to be certain from symptoms alone, the most reliable way to know your status is a blood test from your GP. However, if your diet is low in leafy greens, beans, and citrus fruits, you may not be getting enough.
2. What’s the difference between folate and folic acid?
Folate is the naturally occurring form found in foods like spinach and broccoli. Folic acid is the synthetic (man-made) form used in supplements and for food fortification. Folic acid is more easily absorbed by the body than folate from food sources, which is why it’s used for supplementation.
3. Can I take too much folic acid?
While folic acid is a water-soluble vitamin, taking excessively high doses (above 1,000 mcg per day) over a long period is not recommended. Always stick to the dose recommended by your healthcare provider to ensure safe and effective supplementation.
4. Should I take folic acid with food?
You can take folic acid with or without food, but taking it at the same time each day helps make it a consistent habit. The most important factor is ensuring you take it daily to maintain adequate levels.
5. Can I get enough folate from my diet alone in the UK?
While a healthy, balanced diet is rich in folate, it is very difficult to get enough to meet the specific needs of a developing baby through food alone. That is why the NHS recommends supplementation for all women who could become pregnant, even those with a healthy diet.
6. How long does it take for folic acid supplements to build up in my body?
It is recommended to take folic acid supplements for at least three months before conception. This allows your body to build up sufficient stores to support the critical early stages of fetal development, with continued intake through the first trimester.
Folate is a non-negotiable nutrient for a healthy pregnancy and overall wellbeing. With the vast majority of UK women having suboptimal folate levels, relying on diet alone is often not enough. The UK’s mandatory folic acid fortification and clear NHS supplementation guidance provide an evidence-based strategy to prevent devastating birth defects. By understanding your nutritional needs and following this advice, you are taking a simple, proactive step. A daily, high-quality folic acid supplement is a safe and effective way to protect your future child and support your own health.
