Folate (vitamin B9) and its synthetic form folic acid play essential roles in DNA synthesis, cell division, and the production of red blood cells. The distinction between the two matters practically: folate is the naturally occurring form found in food; folic acid is the synthetic form used in supplements and food fortification, which has a higher bioavailability than food folate.
Why Folate Matters: The Neural Tube Story
Folate's most clinically significant role is in the prevention of neural tube defects — serious birth defects affecting the brain and spinal cord (including spina bifida and anencephaly) that develop in the first 28 days of pregnancy, often before a pregnancy is confirmed. Adequate folate intake in the weeks before and after conception significantly reduces neural tube defect risk.
The UK Chief Medical Officers advise that all women who could become pregnant take a daily 400 microgram folic acid supplement, and continue this through the first 12 weeks of pregnancy. Women at higher risk (previous neural tube defect pregnancy, taking certain medications, or with BMI over 30) are advised to take 5mg daily on medical advice.
Folate Beyond Pregnancy
Outside of pregnancy, folate is important for: homocysteine metabolism (elevated homocysteine is associated with cardiovascular disease risk); red blood cell production (folate deficiency causes megaloblastic anaemia); and cognitive function (particularly in older adults, where folate and B12 deficiency together are associated with cognitive decline).
Best Food Sources of Folate
Folate is found in highest concentrations in: dark leafy green vegetables (spinach, kale, broccoli, Brussels sprouts); legumes (lentils, chickpeas, black beans); liver (the richest source per gram, but avoid in pregnancy due to vitamin A content); fortified breakfast cereals; eggs; and citrus fruit. The UK government considered mandatory folic acid fortification of flour for many years and began a phased introduction from 2024 — this will increase population intake from staple foods.
MTHFR and Methylfolate
Some people carry variants in the MTHFR gene that reduce their ability to convert folic acid to the active form (methylfolate/5-MTHF). For these individuals, methylfolate supplements may be more effective than standard folic acid. If you have had a neural tube defect-affected pregnancy despite adequate folic acid supplementation, genetic testing for MTHFR variants may be worth discussing with your GP.
