Folate, a.k.a. folic acid or folacin, is a water-soluble B vitamin. Dietary sources include green leafy vegetables, meat, organ meats, poultry, seafood, legumes, seeds and whole grains.
A sufficient supply of folate is especially important for women of child-bearing age to help prevent neural tube defects in embryos during pregnancy.
As with all other water-soluble vitamins, excess intake of folate is excreted and not stored in the body.
