Folic Acid: What It Does and Why You Need It

One small vitamin can prevent major problems during pregnancy — that’s folic acid. It helps your body make new cells, supports healthy red blood cells, and lowers the risk of neural tube defects in developing babies. You don’t need a medical degree to use it smartly; a few practical steps go a long way.

How much should you take?

For most adults, 400 micrograms (mcg) of folic acid daily is a good target. If you’re trying to get pregnant or are in early pregnancy, doctors usually recommend 400–800 mcg daily because this is the window when neural tube defects occur. Pregnant women often take around 600 mcg total from diet and supplements combined. Don’t self-prescribe very high doses — synthetic folic acid above 1,000 mcg daily can mask vitamin B12 deficiency and should only be used under medical advice.

If you have conditions or take medicines that affect folate (like certain anti-seizure drugs or methotrexate), your doctor may suggest a different dose. Some people carry an MTHFR gene change that makes it harder to convert folic acid into its active form. In that case, a form called L-methylfolate may be recommended by a healthcare provider.

Food sources and simple tips

Get folate from food first. Good sources include leafy greens (spinach, kale), legumes (lentils, chickpeas), fortified cereals and bread, oranges, and liver. A quick plate idea: toss cooked lentils into a salad with spinach and orange segments — that’s a folate boost without pills.

Want an easy routine? Take one standard prenatal or multivitamin with 400 mcg of folic acid every morning with breakfast. If you’re a woman of childbearing age, start this even before trying to conceive — the neural tube forms very early, often before you know you’re pregnant.

Watch for signs of low folate: tiredness, pale skin, mouth sores, or unusual shortness of breath. Those can also signal other issues, so get a simple blood test (serum or red blood cell folate) if you’re worried.

Quick safety notes: don’t assume more is always better. High supplemental folic acid can hide B12 deficiency and may interfere with some medications. If you take prescription drugs or have a chronic condition, check with your clinician about the right dose and form.

Bottom line: folic acid is a tiny nutrient with big benefits, especially before and during early pregnancy. Eat folate-rich foods, take a 400 mcg supplement if you might become pregnant, and talk to your doctor if you have health concerns or take interacting medicines.
