Absorb Folic Acid Eat good food sources of folic acid every day. Some good sources are asparagus, brussels sprouts, spinach, romaine lettuce, colard greens, and broccoli. Other good sources are black-eyed peas, cantaloupe, orange juice, oatmeal, whole grain cereals, wheat germ, and liver and other organ meats. Eat fresh, raw fruits and vegetables often. Don't overcook food.
Heat destroys folic acid.
Take the daily vitamin supplement your doctor suggests or prescribes. Don't drink alcohol. It interferes with absorption of folic acid. Some cereals also have vitamin B-12 added to them. The cause for this needs to be identified and treated.
