Is Caffeine Dangerous During Pregnancy? Here’s What Experts Say

Pregnancy comes with a long list of dos and don’ts, from sushi and soft cheese to herbal teas and deli meat. But one question continues to spark debate: Is caffeine dangerous during pregnancy?

Typically moderate caffeine consumption is generally considered safe, but it depends on amounts on a case by case basis.

What Research Says

According to the American College of Obstetricians and Gynecologists (ACOG), consuming less than 200 milligrams of caffeine per day, about one 12-ounce cup of coffee—is unlikely to pose a risk to pregnancy. That amount has not been linked to miscarriage or preterm birth in healthy individuals (ACOG Committee Opinion No. 462, 2010).

However, research also shows that excessive caffeine intake can affect fetal growth and may increase the risk of low birth weight. A 2020 study published in JAMA Network Open found that even low to moderate caffeine consumption was associated with slightly reduced infant size at birth.

The World Health Organization recommends limiting caffeine intake to less than 300 milligrams per day during pregnancy.

Caffeine Is Hiding in More Than Just Coffee

If you are curious about whether caffeine is dangerous during pregnancy, it is important to consider other areas where caffeine is found.

• Tea (especially black and green)

• Soda and energy drinks

• Chocolate

• Over-the-counter headache medications

• Some protein bars and supplements

Because caffeine can cross the placenta, your baby is exposed to it too, and the developing fetus metabolizes caffeine more slowly than adults do.

Every Body Reacts Differently

Some people may feel jittery or experience increased heart rate after even small amounts of caffeine. Others may have no symptoms at all. Pregnancy also alters how your body processes caffeine, making its effects more noticeable than usual.

If you have a history of high blood pressure, anxiety, or pregnancy complications, it’s especially important to talk to your doctor before continuing with daily caffeine.
