Is Green tea safe during pregnancy?
About 29 mg caffeine per 8-oz cup — lower than coffee, but it still counts toward the 200 mg/day limit.
What the sources say
ACOG says moderate caffeine — under 200 mg a day from all sources — is not linked to miscarriage or preterm birth. Mayo Clinic lists brewed green tea at about 29 mg per 8 oz; FDA lists about 37 mg per 12 oz. Green tea extract supplements are different from the drink and are not covered here — ask your clinician before taking them. While breastfeeding, CDC considers up to about 300 mg/day (2–3 cups of coffee) low to moderate; newborns and preterm babies clear caffeine slowly, so less may be better.
