What is the maximum recommended caffeine intake per day during pregnancy?

The maximum recommended caffeine intake during pregnancy is generally considered to be 200 mg per day. This guideline is supported by various health organizations, including the American College of Obstetricians and Gynecologists, which suggests that limiting caffeine can help reduce the risk of potential negative outcomes associated with pregnancy, such as low birth weight or miscarriage.

Caffeine can cross the placenta, potentially affecting fetal heart rate and development. Research indicates that higher levels of caffeine intake may be linked to adverse pregnancy outcomes, which is why recommendations are conservative. The threshold of 200 mg is also based on balancing the potential benefits of caffeine, such as improved alertness and mood, against the risks to both the pregnant individual and the fetus.

The other suggested amounts—400 mg, 300 mg, and 250 mg—exceed the generally recommended limit, which could increase the risk of complications during pregnancy. Thus, it’s prudent for individuals who are pregnant to stay within the advised limit to ensure both their safety and that of the developing fetus.
