Green tea is generally considered safe to drink during pregnancy when consumed in moderation, typically 1 to 3 cups per day. It contains caffeine, about 28 mg per 8-ounce cup, and catechins, which may interfere with folic acid absorption if consumed excessively. Moderate intake of green tea can provide antioxidant benefits and mild energy boosts, but high consumption can pose risks such as reduced folate levels that are important for fetal development, and excessive caffeine intake which may impact fetal growth. It is recommended to keep caffeine intake below 200 mg per day during pregnancy to reduce risks such as miscarriage and low birth weight. Pregnant people should balance green tea intake with prenatal vitamins to ensure adequate folate and avoid overconsumption. Consulting a healthcare provider about individual circumstances is advised.

• Catechins in green tea may reduce folic acid absorption
• Excessive consumption may risk fetal development issues
• Benefits include antioxidants and mild energy boost without jitteriness
• Prenatal vitamins can mitigate folate absorption concerns
• Always consult a healthcare provider for personalized advice
