How Much Caffeine Crosses the Placenta and What Are Safe Limits During Pregnancy?
Learn how caffeine crosses the placenta, safe daily limits during pregnancy, and potential risks of excess intake for fetal health.
80 views
Caffeine can cross the placenta, and because a fetus's metabolism is still developing, it can take longer for it to process caffeine. The recommended limit is up to 200 mg per day (about one 12-ounce cup of coffee). Exceeding this guideline may increase the risk of complications such as low birth weight or preterm birth. To be cautious, try to monitor your daily caffeine intake from all sources, including tea, chocolate, and certain medications.
