Folic acid, iron, calcium, vitamin D, and a ceiling on vitamin A. Today you read the prenatal vitamin label and check the numbers.

Four weeks and three days. Today is five minutes with a bottle and its tiny print: what's in it, how much, and what's not supposed to be.

Your baby

About 2mm long and growing rapidly (NHS). Folic acid is today's subject because its work is happening now: taken before and during pregnancy, it reduces the risk of spina bifida, anencephaly, and some heart defects (MedlinePlus), and neural tube defects form in the first few weeks of pregnancy, often before a person knows they are pregnant (CDC).

Your body

The numbers change once you're pregnant. During pregnancy you need 600 mcg of folate a day from foods and/or vitamins, and most people need a supplement to reach it (MedlinePlus). Iron goes to 27 mg a day because your blood volume rises; calcium is 1,000 mg a day for adults and 1,300 mg for pregnant teenagers aged 14 to 18; vitamin D is 600 IU a day (MedlinePlus). The NHS puts it more simply: 400mcg of folic acid daily until at least week 12, and consider vitamin D (NHS). The Office on Women's Health says 400 to 800 mcg of folic acid, continued throughout pregnancy (OWH).

Most prenatal vitamins contain 800 to 1000 mcg of folic acid (MedlinePlus), so one pill usually covers it. Two cautions: only take vitamin and mineral supplements that a health care provider recommends (MedlinePlus), and the daily prenatal should contain no more than 5,000 IU of vitamin A (OWH).

Try today

  1. The prenatal vitamin label

    Time: 5 minutes, bottle in hand

    1. Find the folic acid line. Most prenatals list 800 to 1000 mcg (MedlinePlus); the pregnancy target is 600 mcg a day from food and vitamins together (MedlinePlus).

    2. Find iron: 27 mg a day is the pregnancy figure (MedlinePlus).

    3. Find vitamin A and check it's 5,000 IU or under (OWH).

    4. Anything else on the shelf, herbal remedies included, goes on a list for your provider; the AAP says to make sure your doctor knows about every other supplement you take (AAP).

    5. Take vitamins only in the doses your doctor recommends (AAP).

    Make it work:

    Food folate counts, but not equally: folate from foods like orange juice and leafy greens is not absorbed as well as folic acid (NICHD).

Watch for

  • Normal

    a queasy stomach after the pill; the iron in prenatal vitamins can irritate the stomach (MedlinePlus).

    Call your provider

    if you vomit blood or material that looks like coffee grounds, or lose more than 2 pounds (1 kilogram) in a week (MedlinePlus).

  • Normal

    needing more sleep than usual in the first trimester (MedlinePlus).

    Call your provider

    for tiredness that is overwhelming rather than just more; the CDC lists it among the urgent warning signs (CDC).

  • Normal

    tearfulness and mood swings from hormonal changes (NICHD).

    Call your provider

    if low mood or worry doesn't lift; anxiety during pregnancy is as common as depression, both can be treated, and the sooner you start the sooner you feel better (AAP).

For you

If the vitamin turns your stomach, move it. MedlinePlus's advice is to take prenatal vitamins at night and with food, since the iron can irritate the stomach (MedlinePlus). Same pill, better hour.

Don't add anything for the nausea on your own: "Do not take any medicines for morning sickness without talking with your provider first" (MedlinePlus).

If you're the partner: a bottle that lives next to the kettle gets taken; one in a drawer doesn't. Move it, and notice when it's running low.
