Folate is a B vitamin. Natural sources are found in green leafy vegetables, nuts, meat, poultry, beans, fruit, seafood, eggs, grains, liver, spinach, asparagus and Brussels sprouts. Some cereals and other foods are fortified with a form of the vitamin called folic acid. It is necessary to make DNA. It also prevents birth defects in the brain and spina bifida. It is critical that pregnant women and women who intend to become pregnant get adequate levels of folate in their diets. A supplement may be recommended. Prenatal vitamins for women often contain approximately 400 micrograms of folic acid. People who suffer from alcoholism or who have malabsorptive disorders like celiac disease or inflammatory bowel disease (IBD) may suffer from folate deficiency. Ask your doctor if a supplement is in order if you have these conditions.
