About Folate
Folate (vitamin B9) is essential for DNA synthesis, cell division, and the formation of red blood cells. It is critically important in the first weeks of pregnancy — adequate folate prevents neural tube defects such as spina bifida, which is why supplementation (400 µg/day) is recommended for anyone who may become pregnant. Leafy greens, legumes, fortified foods, and citrus are rich sources. Cooking destroys 50–90% of folate — raw and lightly cooked vegetables retain more.
Megaloblastic anaemia (large, immature red blood cells), fatigue, and — in early pregnancy — neural tube defects in the developing fetus. Folate deficiency is the most common vitamin deficiency in the UK.
High folate intake from food is not harmful. However, high-dose folic acid supplements can mask the symptoms of vitamin B12 deficiency, allowing B12-related neurological damage to progress undetected — a particular risk on plant-based diets. The upper limit for folic acid supplements is 1,000 µg/day.
