Folate
Folate (vitamin B9) is a B vitamin needed for cell division and the formation of red blood cells.
Folate, or vitamin B9, is a B vitamin the body needs for making DNA, for cell division and for forming red blood cells. It works closely with vitamin B12. The level in the blood mostly reflects recent intake. Retesting shows how it changes over time.
Intake of leafy greens, legumes and fortified foods is the main factor. Alcohol lowers folate, the need is higher during pregnancy, and some medicines affect it. Folic acid supplements raise the level.
Foods that help
Leafy greens such as spinach and kale, legumes, avocado, beetroot, citrus fruit, whole grains and eggs.
Foods to limit
Alcohol reduces folate uptake. Large doses of folic acid supplements raise the level well above what food provides.
