England's Folate Gap: Declining Pre-Pregnancy Folic Acid Use and Fortification Plans

The Conversation reports a decline in folic acid use before pregnancy in England, with fewer than one in five women taking it now. The article notes this drop could hamper progress in preventing birth defects linked to low folic acid intake, even as December 2026 fortification of non-wholemeal flour with folic acid rolls out. It argues that fortification alone is not enough, since many pregnancies are unplanned and the fortification level may miss important staples. The piece calls for continuing daily folic acid supplements for those trying to conceive and during early pregnancy, plus targeted pre-pregnancy care and clear public messaging to avoid undermining supplement use.

• Folic acid before conception reduces neural tube defects
• Fortification improves population folate but won't reach all foods and demographics
• Many pregnancies are unplanned, so supplements stay essential
• Education and pre-pregnancy care are needed alongside flour fortification

Overview

The Conversation highlights a worrying trend: fewer than 20 percent of women in England are taking folic acid before pregnancy. This shift raises concerns about neural tube defects in newborns, even as the government prepares to mandate folic acid fortification in non-wholemeal flour starting in December 2026. The piece emphasizes that while fortification can raise folate levels across the population, it is unlikely to fully prevent birth defects on its own. It argues for a holistic approach that includes continuing daily folic acid supplementation for women who are trying to conceive and during the first trimester, alongside timely pre-pregnancy care and clear public messaging to ensure supplements remain part of women’s health planning.

UK Fortification Policy and its Expected Impact

The proposed UK policy adds a low level of folic acid to non-wholemeal wheat flour, specifically 0.25 mg per 100 g. Government projections estimate this could reduce neural tube defects by about 20 percent, preventing roughly 200 cases per year. While welcome, this level of fortification falls short of reductions observed in countries with higher fortification coverage. The approach also excludes wholemeal flour, some imported products, and many non-wheat staples, which means significant portions of the population may not receive adequate folate protection. England’s chief medical officer Chris Whitty has described fortification as a simple and effective measure, but stresses that supplements remain important for women who may become pregnant.

Uptake Gaps and Determinants

Uptake before pregnancy is consistently lowest among Black and Asian women and those living in deprived areas. Regional disparities exist, with uptake well below the national average in the north east and the west midlands. Several factors influence whether women take folic acid before pregnancy: not planning a pregnancy, not knowing when folic acid is needed, belief that a healthy diet suffices, or lack of access to pre-pregnancy care. Prior pregnancy experience does not necessarily boost supplement use; some women who have had healthy pregnancies previously are less likely to take folic acid in later pregnancies due to unplanned or later pregnancies and competing childcare responsibilities. The article suggests knowledge alone cannot close this gap.

Why Fortification Isn’t Enough

The timing of folic acid is critical because neural tube closure happens by about four weeks after conception, often before a woman knows she is pregnant. As many pregnancies are unplanned, relying on supplements alone fails to reach all at-risk women. Mandatory fortification is valuable because it does not depend on pregnancy planning and can raise folate levels across the population, including those who do not take supplements or who have unplanned pregnancies. Nevertheless, fortification at low levels cannot provide full protection, and there is a risk that people will assume supplements are unnecessary when flour is fortified. Canada, the US, Chile and Australia demonstrate how fortification can reduce neural tube defects, though the UK aims for partial protection rather than fully universal fortification.

Path Forward: A Combined Strategy

Experts argue that fortification should be complemented by timely education, pre-pregnancy care, and improved access to preconception services. England’s plan needs to be paired with robust public health messaging to avoid misinterpretation that supplements are no longer needed. The aim is a system that combines population-wide fortification with education and care before and between pregnancies, giving every woman the best possible protection against birth defects.

Conclusion

In sum, fortifying flour is a long overdue step toward population health, but it is not a panacea. A holistic approach that pairs fortification with education, pre-pregnancy care, and accessible health services is necessary to maximize protection against neural tube defects and ensure equitable outcomes across all groups.
