According to the American College of Obstetricians and Gynecologists (ACOG), pregnant women should limit their caffeine intake to 200mg per day (ACOG, 2020)[1]. This is equivalent to about one 12-ounce cup of coffee. Understanding these limits is crucial for maintaining a healthy pregnancy.

How Caffeine Affects Pregnancy

Research has shown several ways caffeine can impact pregnancy (Greenwood et al., 2014)[2]:

  • Caffeine crosses the placenta and reaches the fetus
  • It can affect fetal heart rate and metabolism
  • May impact nutrient absorption and blood flow
  • Can influence maternal blood pressure and heart rate

Potential Risks and Complications

Studies have identified several potential risks associated with high caffeine consumption during pregnancy (Chen et al., 2016)[3]:

  • Increased risk of miscarriage
  • Low birth weight
  • Preterm birth
  • Developmental delays
  • Sleep disturbances in newborns

Caffeine-Free Alternatives

1. Safe Beverage Options

There are many caffeine-free alternatives that are safe during pregnancy (Mayo Clinic, 2023)[4]:
